Which IBM IEEE card? There are at least 2, and they

different. I was given an IBM IEEE488 card which uses a pair of 9914
chips (one for data transfer, one to send commands, I think). The one in
the O&A Techref is based round a NEC 7210 chip.
My Brain Boxes card has a 7210 chip, plus the two IEEE bus
buffer chips and a bunch of PALs, buffers, etc. for the ISA
bus. There are six DIP-switches for the base address and
mode, plus some jumpers for IRQ and DMA settings.
