Hi folks, A friend of mine in the UK is looking for any info on the following boards. The CPU board is marked ?VA 03-907023-00? and features a Z80 with 16K RAM and an 18.432MHz crystal. The backplane is also VA and has 11 132-pin slots that aren?t all identical implying usage for different cards in those locations. Voltages are +5/-5/+12V. Pics:
