G'day $ALL. Quick question. I've just snaffled an M8190-AE with what I think is the 21-21853-06 FPU as an upgrade for either the 11/70 or 11/23Plus at home. I've seen reference to CIS microcode for these boards about the place and am extremely keen to have a go at it with macro. I'm not "actually" sure if it has it in the PROMS, but being handy with a EPROM programmer hopefully I can find it. Does anyone have any reading material on how to figure out if the CIS microcode is installed ? Al.
