A Colorful “Peek” at the Graphics Performance of the Apple II

This week Apple held a special event in which it announced a variety of new hardware and services, chief among them being a new model in the Macintosh lineup, the Mac Studio powered by the equally new 20-core M1 Ultra SoC, and the new 27-inch 5K Studio Display. The impressively powerful Mac Studio takes the form factor of a “tall” Mac mini (kind of a IIsi to the mini’s Mac LC). As such, it has gained the nickname “Fat Mac” here and there on the forums. Those who’ve been following the Macintosh scene since the beginning will recognize the colloquialism as a dusting off of the nickname bestowed upon the Macintosh 512K, a model introduced several months later the release of the original 128K Macintosh.

Ahead of their special events, Apple publicizes them with imagery featuring an artistic take on the Apple logo along with slogan. The March 8th event was dubbed the “Peek performance” event and the associated imagery featured a set of rainbow-colored layers that convey a kind of tunnel effect. I love it when Apple brings out the rainbow of olde on their logo in any manner. This one looked quite nice, to me.

While I’m sure that there’s little hardware out there that could render such a vibrant and colorful image better than the Mac Studio with its accompanying Studio Display, I thought I would see how good a job one of the Mac’s grandfathers — my trusty 128K Enhanced Apple IIe — could do. And, so, I reached to Bill Buckel’s Bmp2DHR image converter, which I detailed in a post several years ago, to get the job done.

I grabbed the “Peek performance” logo from Apple’s website, adjusted and reduced it in size to a true-color, 640×480 pixel BMP image file (one of the acceptable input formats of the b2d program), and on the command line had the program convert the BMP to a 16-color Double High-Res image file, 16K in size. I then used Jason Harper’s ][GIF image viewer to display the image on my Enhanced Apple IIe equipped with a VidHD graphics adapter from John Brooks.

In the image above (click for a closer look), the lower display is the Apple ColorMonitor IIe outputting NTSC video directly from the IIe’s video out jack, while the upper is a wide LG LCD display showing the image as generated by the VidHD interface, connected via HDMI.

There are lots of images / slideshows out there that show off Buckel’s conversion algorithms on the Apple II but, of them, I think that this is one of the most striking to behold. What a lovely retro-leaning rainbow glow. (Several comments on the image where I posted it on social media expressed serious doubts that the Apple IIe was actually generating the display…) It even looks great in black & white Atkinson dither in the Apple II’s High-Res mode (280×192 pixels) display, I have to say!

Those looking to do their own “modern to retro” image conversion for their Apple IIs can grab the aforementioned Bmp2DHR command-line toolset, but some may have an easier time with Dagen Brock’s Buckshot, a program which provides many of the features of Buckel’s converter, all wrapped in a nice UI with image preview and various other features.

Floppy disk

In an effort to “bring the rainbow to you,” I have created a bootable ProDOS disk image containing both the DHGR color and HGR black & white images along with the ][GIF viewer. Grab it and give it a look on your own Apple II, if you’ve got the hardware!

[ Thanks for the inspiration, Rich! ]

    I’d consider by now https://github.com/KrisKennaway/ii-pix the most advanced DHGR converter. However, it’s a REAL pain in the neck to install!
