IN my continuing Digitalker saga, I did find a couple not horribly priced Digitalker ICs online and purchased them.  As one arrived, I found that my original IC was actually OK, but the cable from the computer to the device has issues. I've traced it to what looks like a heavy duty 16 pin IC s

PDP-8/I vs 8/E EAE

Has anyone noticed a difference in DVI overflow behavior on the PDP-8/I EAE versus the PDP-8/E EAE? The 8/E EAE claims to be 8/I compatible in Mode A, and I think I agree, for the most part. At least, it's compatible for the parts that matter. When a DVI instruction results in overflow, the EAE im

I've got rights to a fairly nice system located in St. Louis.  It has working streaming tapes as well as half inch, all working. It is on till this coming weekend. The full system is a single bay, I've been told is 7' tall on casters.  I won't let it be scrapped if possible, but I'd like it
