what's a floppy?
...sorry couldn't resist. i've used more than my share of 8" floppies
back when everything was on them. OS, data, tools, everything.

My first real programming language, and still my favorite, is Z80
assembler. That's one reason one of my hobby things is getting boards
fabricated for a retro computer known as the CPU280, which is
currently the only hobbyist-buildable and open-design Z280 computer
out there. Runs the amazingly modern CP/M 3 operating system, and can
run the Unix V7-semicompatible UZI280. No GUI, of course, but still a
fun little rig. 12MHz Z280 (16-bit enhanced Z80) with 4MB of RAM and
floppy interface (I use an HxC floppy emulator that uses disk images
on SD cards) with an ECB connector for an ECB backplane, and there is
an IDE interface available for that. Typically you then use
industrial 64MB to 128MB CF cards with an IDE to CF adapter.... lots
going on in this 'retrobrew' scene; check out
www.retrobrewcomputers.org for more! (including a PDP8-compatible
single board computer with CF storage using the decidedly retro
6120-based CPU chipset.... complete retro computers running inside
FPGAs..... new-old Z80 designs..... even a single-board 68030 that can
it was taking a 'long time' so i wrote it in assembly (intel). intel
has a special instruction to look for chars. that helped.
If you're really into the assembler scene on PCs, you gotta try
MenuetOS ( http://menuetos.net/ ) which is a modern, pre-emptive,
real-time, multiprocessor OS for the PC written entirely in 32/64 bit
assembly language. Full GUI and everything. The basic OS fits on a
single floppy. Several apps available, including a non-free media
player that can play DVD's, for a bit under $12.
