Just a quick HP-1000 memory question while we're all discussing it... I have a single 12747H board in my 2113E.. is it correct to jumper it for 0-64K? That would be my guess, as it is the only memory present.. I'm thinking the fact that it was jumpered as 960K-1024K may have contributed to my machine's failure to work, heh.
