The 3 core sets, accordind to your earlier post are the G110, G231, and
H214. these are 8kw each. Maybe the Monilithic will work and that might max
Think of the bipolar as very fast extra memory. It can sort of act like a
cache memory, and can help with processor throughput. I thought there were
2 controller boards and 4 G401s, but one is better than none. You can check
that on the top of the processor box in the module chart.
