RE: [N8VEM-S100:38] Re: Z80 and SIO board running
Kenro, I'm running all my S100Computers.com type boards here at 10MHz (+
two I/O wait states). Cannot speak for other boards.
As it turns out I have just revisited the IDE board we did this time last
year. I want to do a dual drive/ CD card version, so I have been thinking
about software for it again. Am redoing the diagnostic program right now.
As to a kind of plug & play approach the issue, is it becomes equation of
benefit/effort. If it's to help people get around the chicken/egg bringing
CPM up the first time from a PC I thinking perhaps dump everything on a
partitioned drive/CF card under MSDOS/windows and have a simple S-100
program suck it off one time to get CPM going. This allows each person to
fine tune their BIOS etc. first.
For regular transfers once up, I describe here how I do it over a serial
Not pretty, but works very well. Unfortunately I don't have the time to do
a proper Windows/CPM shared approach - I 'm hoping somebody else will.

I have the eprom/ram board working with 1M and have modified the monitor
program to work with the sio as the console. Last night I started checking
out the ide board and my Z80 board quit working.
After replacing a chip that died, it's running again. I tried an 8Mz osc and
things seem to work fine at that speed. Back to ide board. Any ideas on how
to load the flash drive from a pc?
