The double 'r' in the spelling of my handle
is on purpose. Zerro is pronounced as zero.
I have used this handle since the 1980s, and the spelling is an inside joke from my youth
Apple II

Apple II

The Apple II series of computers are amaizing in there own way. They are the 8-bit computers I still use most for day to day stuff. They may not have the popularity of the likes of the Commodore 64, though they still have a huge following of there own.

Starting from the original Apple II in 1977, evolving through the Apple II Plus that added more memory and Applesoft BASIC as standard, and on through the IIe, IIc, and ending in the high end 16-bit Apple IIgs. Woz had it correct, a single series of backward compatible computers that are continously upgraded. Had this model been folowed instead of wasting time on so many side projects, Apple Computer would have likely outdone the PC Clones. Especially as the Laser 128 had showed the legal way to clone the Apple II, by licensing AppleSoft BASIC from MicroSoft.

While technically a 16-bit system with an 8-bit data bus, the Apple IIgs is the memeber of the series that I mostly use. Unfortunately I do not have a working IIgs at this time, so must use emulation. The Apple IIgs had everything going for it, it was very well backwards compatible with the rest of the Apple II line, and it was also as advanced as most 16-bit computers of its time.

One of the things I have always liked about the entire Apple II series of computers is that they do not have any Sprite HW, you have to do sprites in software, adding to the challenge, and making anything with sprites more fun to write. I do like the fill mode of the IIgs Super-HiRes modes, as it still presents a good challenge, while making solid color filled areas simple (such is used in flat shaded polygons in 3D graphics).

The older members of the Apple II series have very minimal sound ability as stock. Most people had some kind of sound board, usually a Mockingboard. Though with the IIgs we end up with a sound system easily as capable as any other home computer of the time, and better than most.


The chosen color scheme for the Apple II related pages is roughly modeled on the standard Apple IIgs border blue, with the common black background and light grey text used by most 65C816 Assemblers on the Apple IIgs.

For those that remember the old days;
