Hi Dave, >Also, you've used ISA and put two slots on the boards. How did you arrive >at the decision of two slots? What compromises/benefits does this provide? >I imagine the cost of extra PCB size was a large element.
Yes, it was mainly the extra cost for a bigger PCB. And a little bit the idea of having a very compact QL system in a custom case. (Which has not materialized yet.) The Q40/Q60 mainboard electronics are designed to drive up to 5 extension slots though. A passive slot riser allows to use this feature. A few folks have their Q40/Q60 in an old Slimline case (they came with ISA slot risers) for this reason. All the best Peter
