A Few Words from a “No Man’s Sky” Time Traveler

As those who follow me on any of my social feeds are quite aware, I enjoy the game No Man’s Sky. Actually, that’s something of an understatement. I’ve written quite a few words about the degree to which the boundless universe that Hello Games has given us to explore has captivated me in various blog posts over the past two and a half years. In the first of these, written three weeks after the game launched back in August 2016, I explained,

All my life I have dreamed of exactly this in gaming — an interesting, alternate universe, massive in scale, in which I can freely wander and explore at my own pace. That is what No Man’s Sky is to me, and it’s my observation that many others are similarly moved by the game. The fact that the universe is procedurally generated and that even the game’s creators can’t describe everything that’s out there to be encountered ads to the incredible sense of the unexplored, the alien. There is a lovely feeling of solitude to the whole experience of discovering a world, leaving your mark on it, and moving on to the next.

No Man's Sky Foundation ice worldI began playing the game on the PS4 back on its launch day in August 2016. I was so completely drawn into it that just a few weeks later I decided to build a high-end gaming PC — something I hadn’t done in many years — in order to get the best experience possible in the No Man’s Sky universe. The system I built was able to achieve a higher resolution at a higher frametrate than the PS4, as well as allowing mods to be run (which, in the end, I decided to stay away from in the interest of experiencing the gameplay as intended by the developers).

It wasn’t until a week ago, however, that it enabled me not only to travel across the vast and myriad galaxies within the universe at the heart of the game, but to travel back through time within that universe, as well.

Let me explain.

A Look at the Short-Lived 3-Inch Compact Floppy Disk

Compact Floppy Disk logoI was recently listening to the latest episode of Retro Computing Roundtable podcast during which there was mention of a 3-inch floppy disk. No, not 3.5-inch, but 3-inch. These disks are known as Compact Floppy Disks (also “CF2”) and were used in a number of systems outside the US, including some models of Amstrad, Tatung, and MSX machines. And, while the Sony-engineered 3.5-inch disks that those of us who don’t think that they are 3D-printed takes on the “save icon” know well are more or less square, these disks are rectangular. This was a curiosity discussed in the podcast at length.

Magazine ad for Amdisk-I driveThe Compact Floppy Disk form factor was engineered by Matsushita and Maxell and, in the states, it was offered for a variety of machines by Amdek as an standalone unit. The Amdek Amdisk-III was a dual-drive unit released in 1982 at an introductory price of $899, offered for the TRS-80 CoCo and the Model III as well as the Atari 8-bit line. Amdek also sold a single-drive Amdisk-I unit exclusively for the Apple II, billed as a perfect second-drive option. I saw an ad for the latter when I was using an Apple IIe as my main system and it appealed for it’s cool-factor, but was too expensive. Eventually I saw a close-out deal for the Amdisk-I at a price of about $75 and I went in on it. When it arrived it came with four blank 3-inch floppies and I plugged it into my Disk II controller card and installed the third and fourth floppy-sides of Ultima IV on it and played away. It was reliable and, as expected, pretty cool.

I sold the system it was attached to and moved to an Atari ST, but I kept one of the disks. After hearing the discussion on the RCR podcast about the oddness of its rectangular form-factor, I decided to dissect the disk I have on hand to see and share just what’s inside. Would there be a magical storage space for trinkets? Something special waiting for the adventurous user who decided to crack a disk open? As it turns out — no. There’s just a spring and an overall situation that presented no particular reason for it being non-square.

Having cracked open the disk, I present the photos here for posterity. I’ve been without a drive to read this disk for over 20 years, and so the destruction of the media is of little pain for me. The magnetic media of yesteryear (some even less common than these) is an interesting thing to examine, I think.

‘Twas No Post, But Poetry! (At 300 Baud)

It is not every day that BBSing moves a man to poetry….

Apple ColorMonitor IIe showing a BBS post that is a poem

But, there are occasions where it does, as reddit user u/droid_mike proved this past weekend as r/Retrobattlestations‘ BBS Week IV competition drew to a close. The competition rules required participants to make a post to the subreddit’s official BBS, Level 29, and show proof of the post by photographing the screen or a printout of the session. Mike’s post is a poem that harkens back to the recent holidays and tells the tale of hardship that is his (successful) attempt at getting his TRS-80 Model 100 dialed (over the telephone lines) into the BBS, and at 300 baud!

While I have provided a photo I took as soon as I encountered Mike’s moving post on Level 29 while logged in on my Apple IIe, I refer you to Mike’s competition entry subreddit post to read the complete text of his soul’s outpouring, a more detailed albeit less poetic account of his attempt, and to see his Model 100 online in all its glory.

I, myself, submitted an entry to the BBS Week IV competition in the form of a photo of my dual-screen, enhanced Apple IIe telnetted into the BBS at 9600 baud (thanks to my WiFi232 unit) and displaying the post I made there detailing the Apple IIe’s overall configuration. However, as the judge will be picking a winner in each of the following three categories: #1 Most cramped screen, #2 Most mechanical, #3 Most artsy fartsy message — I think Mike has a far better chance than I at walking away with a few of the coveted r/Retrobattlestations retro sicker prizes!

My First Taste of CGA “Composite Color”

As a long-time Apple II users I am quite familiar with the technique of generating color video by way of NTSC “artifact color” (also sometimes referred to as “composite color”). The 8-bit Apple II series is incapable of outputting any actual color pixels, so it takes advantage of idiosyncrasies of the NTSC composite video signal by displaying patterns of black and white pixels which are smeared together on-screen in a predictable fashion, resulting in colors that are not actually in the signal.

I’ve spent thousands of hours staring at the artifact colors of an Apple II display, but lately I’ve been exploring something that’s rather new to me: the world of IBM CGA (for Color Graphics Adapter) artifact colors.

I recently got turned on to the notion of putting together a little Tandy 1000HX system, so I looked around and over the Christmas holiday I found one for a very reasonable price on Craigslist, brought it home, and made a space for it in the Byte Cellar. It’s a lovely little machine with a lot of personality and it’s been fun putting through its paces. (I am about to install a variety of expansions to greatly increase its capabilities, and that will be the subject of a blog post to come.) Being a Tandy 1000, it features the enhanced graphics and sound capabilities that IBM introduced with the PCjr, and that puts it well beyond standard CGA as far as on-screen visuals for programs that support its enhanced video modes.

Back in the DOS days I was never much of a PC guy. I briefly drove a Tandy 1000TL in the late ’80s and, later, had the BridgeBoard PC-on-a-card in my Amiga 2000, so I was able to find a few old DOS floppies tucked away on the shelves. I’ve been firing these up on the HX and very few of what I have here support the PCjr/Tandy video modes and, so, I am reminded just how much I dislike standard CGA graphics. The typical palettes of cyan, magenta, white, black and red, green, yellow, black I have always found to be far less appealing than the Apple II’s 6-color hi-res palette.

Well, one of the games I had on floppy was Archon from Electronic Arts. I loaded it up and there was much cyan and magenta to be had on the RGB display, and things looked pretty busy with lots of pixel patterns making up dithered colors. Looking at the patterns, I recalled reading somewhere that it was a CGA game which utilized artifact color and that was written to be presentable both on an RGB monitor as well as via composite output. It occurred to me that the Tandy has a composite output, and the system was sitting next to my gaming TV which accepts composite, so I wired them up. I powered on the TV and, voila! I got my first taste of CGA artifact colors — and just how much better they looked than plain old RGB CGA!

The TI Goes A-Caroling for Holiday Music Week VI

The sixth annual Holiday Music Week is happening over at r/Retrobattlestations and this year, for my entry, I set the TI-99/4A to singing a song of the season, with some help from John McGinley who wrote the Christmas demo that can be seen, here, running on the TI. He wrote the demo in TI Extended BASIC (via XB256) earlier this month.

McGinley’s Christmas demo was part of my holiday demos roundup posted earlier this month.

Have a Helping of 8-bit Holiday Cheer! (2018 Edition)

‘Tis the season, and that means it’s time to push out the eighth annual Byte Cellar vintage computer Holiday demo roundup so everyone can feel that warm, fuzzy, pixellated holiday glow. With scanlines. Enjoy! I’ve been a computer geek for a long time now, but I’ve been enjoying The Holidays even longer… I got my first computer, a TI-99/4A, on Christmas morning in 1982. I was 10 years old and from that Christmas on, it was nothing but games and computer hardware that I wanted Santa to leave me under the tree. On through my teenage years, part of my ritual for getting into the Holiday spirit was downloading and watching Christmas demos on whatever system I had at the time. And, apparently I wasn’t alone in this, as Benj Edwards explains in his piece, “The Oddball, Nostalgia-Inducing Christmas Tech Art Of The 1980s And 1990s.” Enjoying these demos is a personal tradition that I had, sadly, long left behind until 2010 (the year before I began writing these posts) when I was inspired to seek out the demo I remember best, Audio Light’s 1985 musical slideshow for the Atari ST. With the help of an emulator, I captured it to share online with readers. A year later, I fired it up again and watched it run through it’s 16-color, pixellated images and 3-voice musical holiday greetings. As I watched, it occurred to me that it might be nice to gather a few of the other demos I remember from the good ole’ days and present them here, in order to try to share some of the holiday cheer that they used to inspire within me. The following list of demos ranges across a variety of platforms of olde and is sure to bring the warmth of the season to the hearts of any and all retrocomputing enthusiasts who behold it. Happy holidays, and I hope you enjoy the shows! Be sure to also have a look at the dozens of demos gathered through the years in the 2017 edition and the 2011 – 2016 edition of this post.

As God Is My Witness, I Thought Turkeys Could Fly

A turkey on the screen of three different home computers

When it comes to the holidays, I get rather sentimental as well as nostalgic, these days. Holidays as a kid are some of the best memories any of us have, really. And having been an avid computer geek during the home computer era, my holiday memories are always laced with fun times on the computer as a kid.

As such, I’ve been running my Holiday Demos post series around Christmas time for quite a few years and it seems I might’ve just started a new Byte Cellar tradition with my recent Halloween Demos post. Well, when I saw a reddit post from u/RogelioP demonstrating a BASIC Thanksgiving demo he typed in from the November 1983 issue of Family Computing magazine, Turkey by Joey Latimer, I had to get on board.

TURKEY.BAS program listingFamily Computing, along with many other computer magazines of the time, offered BASIC program listings in every issue, custom catered to various platforms of the day. (Back in the era of “home computers,” basically every system was its own world, one largely incompatible with the next — even the versions of built-in BASIC varied to such a degree that each platform needed its own particular version of the program in question.) And Family Computing was one of my favorite magazines out there at the time. As a CoCo 2 user, he typed in the CoCo version and brought a Thanksgiving turkey to life on his CRT. Inspired by this, I searched and found that issue on Archive.org and though I’d give it a try on a few systems sitting side by site in the Byte Celler: a TI-99/4A, an Atari 130XE, and an Apple IIgs. Thanks to RogelioP, much of my Sunday afternoon was spent keying a 35-year-old BASIC program into those three systems and recording the results to share. And, I have to say, DATA statements are a mess to debug, and I didn’t get things perfectly sorted, but we’ll just say that the various turkeys have “personality.”

Thanks for the inspiration, RogelioP, and all I can say from here to readers is Happy Thanksgiving!

Update: RogelioP stopped by in the comments and has gotten the Turkey demo running on his TRS-80 Model I, as well. Nice going!

Have a Helping of 8-bit Halloween Horrors!

Animated GIF of filled-vector jack-o-lanternI was at my Amiga 2000 the other night loading this and that scenedemo (demoscene productions) at random, many of which I’d not watched in years, when I ran across a little 40K intro featuring some nifty Halloween-themed elements. With Halloween just a few nights away, that seemed a rather appropriate use of pixellated vectors and it occurred to me to put together a collection of some of the Halloween-themed scenedemos out there for vintage systems, much as I’ve been doing for the past six years for Holiday / Christmas demos.

I’ve written a number of posts on this blog about computing memories around the ghoulish time of the year. For instance, there was the year that an Atari ST saved Halloween for me. I will certainly never forget the year that I plunged blade into pumpkin and created the sinister and ghastly iPod-o-Lantern. And I’ve taken part in several r/Retrobattlestations competitions designed to scare the bytes out of unsuspecting vintage computing aficionados, using an Amiga 1000 on two different occasions as well as an Apple //e.

Indeed, All Hallows’ Eve and vintage computing seem to go rather nicely together. So, without further ado, I hope you enjoy the demos I’ve chosen to scare share with you this season.

Enjoying High-Res Graphics on a Text-Only TRS-80 Model 4 from 1983

The TRS-80 Model 4, like the Model 3 which preceded it, is a curvy, all-in one computer with a 12-inch monochrome text-only display flanked on the right by two full-height 5.25-inch floppy drives, one atop the other. As a kid, nothing to me looked more COMPUTER. I just loved fiddling with them in the Radio Shack down at the mall back in the early ’80s. Ten years ago I won an eBay auction for one, put it on the desk, wired it up as a serial terminal to my Mac Pro, but before long I put it on the shelf to make room for other systems as I wasn’t really doing much with it. Fast forward 10 years and we’ve got these nifty little WiFi232 devices, and the like, as well as inexpensive flash-based floppy and hard disk emulators. So, the Model 4 came down from the shelf and is currently getting some long-needed love. And in my first gesture of love I have lavished the text-only machine with a full 640×240 pixel graphics display, thanks to Ian Maveric’s Improved Grafyx video board.

What inspired me to pull the Model 4 down off the shelf were a number of tweets from telnet BBS pals showing the system being put to great use logged into various systems across the web. Some of the screenshots showed the machine rendering ANSI “graphics” onscreen and I looked into it. As I suspected, the stock Model 4 is not capable of taking on a custom character set such as is needed by ANSI emulation, and I discovered the system had been equipped with a graphics board and the ANSI-supporting terminal program, ANSITerm, was rendering “text” to a graphics display; the character set was basically a software font.

And I just had to go there.

Putting the Atari ST and TI out Front for “Modern Touch Week” at r/Retrobattlestations

Just a quick post here to share a bit of what I was up to this past weekend. It was “Modern Touch Week” over at Reddit’s r/Retrobattlestations which was a competition to show a vintage system using recent / modern enhancement hardware (flash-based floppy emulators, graphics expansions, etc.) in the most extreme or over-the-top fashion possible.

Atari 520ST system photo

To meet the challenge I reached for my Atari 520ST which sports a recently-designed 4MB RAM expansion as well as an HxC 2001 SD-card-based floppy drive emulator that I built into an external floppy drive enclosure, as the original 520ST has no on-board disk drive (a design I prefer to the 1040ST and Falcon with their internal drives). I have never seen an HxC 2001 configuration like this and I consider it rather unique. The system stand / organizer shown is the A520 STation, a stand I had on my first Atari ST back in 1987 and one that that took me years to locate for my current collection.

TI-99 system photo

After submitting that entry it occurred to me that the ST’s neighbor (one to the left in the “Byte Cellar”) better matches the spirit of the challenge. The system I refer to is my fairly well expanded TI-99/4A (the ’99 was my first computer–Christmas 1982), featuring TI’s large, tank-like Peripheral Expansion Unit containing a 32K RAM expansion, a serial / parallel interface card, and a 5.25-inch disk drive and controller card.
