The Software Results COMBOARD was a peripheral for the Unibus, Qbus or VAXBI bus with a 68000 (or 68010) on it. Since we spoke sync protocols out the serial port(s), we had either a COM5025 or a Zilog Z8530, so seeing a Z80-family UART on this board isn't all that strange. IIRC, the DMB32 has a 68000 as well. The other peripheral CPU I've commonly seen is the T-11 - DEC used it on several cards, as did Simpact (a Software Results competitor). I even have a Simpact card, but no software. So what sorts of connectors are coming off the top of the board? 40-pin Berg connectors were commonly used for serial ports (DL11E, DUP11, DUV11...) but with a 3rd party board, there's no standard. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 30-Jun-2004 02:40 Z South Pole Station PSC 468 Box 400 Temp -89.3 F (-67.4 C) Windchill -129.4 F (-89.7 C) APO AP 96598 Wind 10.1 kts Grid 082 Barometer 670.1 mb (11001. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
