Does anyone if its possible to install a MicroSphere Color Graphics board on an '84 series CP/M Kaypro that already has an Advent host adapter (for a RAM disk)? Thanks in advence, Jeff Wieland abp@j.cc.purdue.edu

Jeff, Our (limited) experience at Plu*Perfect Systems with MicroSphere add-on products for Kaypros has been that their software is not relocatable. Thus, although the Advent and MicroSphere hardware should be compatible, and the Plu*Perfect/Advent TurboRom software is relocatable, you may have a problem if you need to put their drivers anywhere other than the hard addresses for which they were assembled. --bridger

Bridger: I didn't think that software would be a problem, since as far as I can tell, one uses Z80 port i/o to talk to the uSphere Color Board. Of course, this could still be a problem if it and Advent's Ram disk happen to use the same port addresses. I'd probably better look into that, too. What I was originally concerned about was that Color Board uses the rear-most SIO chip (socket on a ribbon cable plugs in underneath the SIO), and that since the Advent Host Adapter comes up right next to this chip, it would be physically impossible to install it.
