For people interested in building/repairing S-100 systems Andrew at N8VEM and I at 100Computers.com have just completed the construction and testing of an S-100 bus New Interrupt Controller and Real Time Clock Board. If you would like to read about this board please look here:-
There is a growing list of people getting interested in these S-100 systems. We get these bare boards produced in batches (typically $20-40, depending on demand). So if you would like to try this board you need to contact Andrew or I ASAP. It may be some time until the next batch.
