[cctalk] Heurikon HK68/M10 (Multibus) information?

Does anyone have any manuals or other information on the Heurikon HK68/M10? Or the Hbug ROMs for it? The HK68/M10 is a Multibus 68010 board with serial, SCSI, parallel, timers, 1MB onboard RAM, 2- or 4-channel DMA, and an optional 68451 MMU. It's similar but not identical to the HK68/V10 (the VMEbus version) and so far I haven't been able to find much that would make one usable. I'm particularly interested in: An Hbug ROM. Pinouts for the top edge connectors, which provide the serial ports, the SCSI port, and the parallel port. Jumpering/strapping and other configuration information. And of course it'd be incredible to find the UniPlus+ distribution for it, but I'm not holding out much hope for that. I already know what's on Bitsavers—such as the brochure—and I've already looked at the MAME HK68/V10 emulation, so no need to point those out. -- Chris
