I am trying to bring up an SWP CoPower 88 board in my Kaypro 10 w/ TurboROM. Once I finally figured out that the daughterboard needed to be jumpered for ports 7E and 7F it's trying hard to work. The ramdisk program initializes properly, I can write files to the ramdisk and read them back. But, the screen fills with garbage at every access. Similarly, running MSDOS.COM to boot DOS 2.11 from floppy starts out encouragingly, but also writes garbage to the screen and dies with a complaint of bad command interpreter (it's not, I generated two different diskettes from two different sources). I actually have two CoPower board sets and the other 8088 board behaves the same way (I cannot use the second daughterboard. It's a 'Universal' variant with no port jumpers that isn't seen by the utilities).
So, the question is: Is the CoPower actually compatible with a K10 (4 Mhz. CPU) and TurboROM? Or, does it have dependencies on a slower host CPU speed and/or OEM firmware? Hard to find any hard information on this device so I'm hoping someone here can chime in. Many thanks for any input!
