RE: 80 Series Newbie
HP-85B Update:
The tape drive is back after being refurbished by Larry Atherton at LA Tech Renewal. Got some orange printer belts, too. The unit had been dropped and I've straightened the back panel and repaired the minor case damage. Keyboard has been disassembled, cleaned, and DeOxified. GPIB card installed in vintage PC ready for HPDrive. Also joined the HP Series 80 group on Yahoo. Two questions: 1. Can I burn the Service ROM to a 2764 and plug it into the empty socket on the Logic Board? Just a rhetorical question 'cause I'll try it anyway after verifying the pinouts. 2. Does anyone have the I/O Exerciser Tape files with EDTEST to test the upper 32K of RAM? Dave |
