Tom what is a “Zeta type system”?

Doug and I are working on a version of the ROMwbw CPM that will require an updated rom-ram board. This will be a Zeta type system. So I hope we can get a new one in the que.

Tom.

Guys if there is enough interest I could do another version of the “EPROM” board. Of the 20 or so boards I have done so far it’s the one I’m least satisfied with. I think we could better splice of 8 bit ROMS, and 8/16 bit RAM/EPROMS/Flash on one board with less confusing jumpers etc. The problem is we would need about 20 boards to hit the $30 breakpoint

Doug, Tom, and Leonard;

Excited to hear about your new effort!

http://n8vem-sbc.pbworks.com/w/page/61752020/About%20my%20S-100%20activity

In your deliberations, would you please consider support for the 4MG RAM board (that recent joiners, including myself, have) in addition to the EPROM/RAM/Flash board that I have not (and falls into the unobtanium category at the moment)?

Perhaps the 4MG RAM board can be configured to work comparably so that this dual-support isn't a problem? Online documentation states "You will notice that the board accommodates both static RAM chips, Flash RAM chips and EPROMS (from 2716's all the way up to 27256's)."

I think that explicit support for the 4MG RAM board would open up your audience a bit (more) and aid some of us newbies :->.

Thank you!
