Computer Kit / Plans

When you say you want a kit, would plans do, or do you want to buy a "kit"
with all the trappings? Do you want to have software for it or do you want
to build your own from scratch?

I have some schematics that might be of interest.

If you want to do S-100, I'd STRONGLY recommend sticking with 8085 or Z-80.
I can send you a plan for an S-100 with some board-resident hardware, i.e.
an attached HDD and FDD. It's got some developmental gaps, though, like it
needs a bunch of drivers reworked.

For a 6502, which you can run up to 14MHz but which, for reasons relating to
the serial I/O I recommend you run at 12.288 MHz, I also have a schematic
you might consider. There's some resident firmware available, in the form
of a resident debugger, though I'd move the I/O to elsewhere in the memory
map than where it is in this application.

Do you want to use programmable logic (have you the tools to use it?) or do
you want off-the-shelf logic, which is getting to be less and less
off-the-shelf with each passing day?
