RE: [CAD_CAM_EDM_DRO] OT Re: Gecko connection to unipolar stepper??

Still available:
http://www.imsai.net/

They have a custom board with interface ports, firmware, USB ports and a
Zilog eZ80.
You can then add a full front-panel, a nine-slot S-100 bus and disk
controller.
Boots CP/M and runs all CP/M applications.

You also have the option to add a standard ATX motherboard - this allows
you to run CP/M as a terminal window in either Windows or Linux.

Full-blown system is about $2K but really tempting for the nostalgia
factor.
Plus it would be an awesome windows machine -- the front panel is also
controllable under Windows...


Fun times -- still is!

sister site to the CCED group, as many of the same members are there,
