Anyone can design a great computer on paper. Making a real, tangible part
is a lot more difficult.
Using cool sounding but almost impossible to find parts seems easy but it
makes the SBC practically worthless.
If you can make a low cost Z80 SBC that includes floppy IO, I would love to
see it. I'd even buy one or two.
But when you think about it, most early CP/M machines were
8 inch single density. Not much on a disk and that I think is
the basic format to look at. I think I seen a data separator
using a 16 bit counter at 4x? the data rate but I can't remember
where.
I look forward to seeing your design.
Thanks and have a nice day!
I can't say I am having a nice day.
I am still grumbling over not getting PAD's
PCB and LAYOUT software when I could in
the late 80's. I am looking to do a 16 bit
(2901) cpu using EEPROM (2kx8 250 ns)
and am still trying to find a schematic capture
and PCB layout program that I can afford
with through the whole parts.
Sadly all seem to be Australia. :(
