Hp85a

excellent condition Bill: Here are a couple of useful links: http://ftp.agilent.com/pub/mpusup/pc/old/s80_over.html This is Agilent's page giving some history and configurations of the series 80 machines, including the HP 85. http://www.ebbsoft.com/ This is Eric Bal's somewhat incomplete page that includes quite a bit of HP 85 info as well. You can hook up the HP-85a to certain HP floppy disk drives if you have the mass storage rom, the HP-IB interface and I think you need the I/O rom as well. One drive unit that will work, the HP 82901M, is currently up for auction on eBay at: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item= 1221920807 Current price only $10.49 but will probably end up in the $30-40 range. The tapes you need are DC100A's. HP sold them as either HP 98200's or HP 200 Series 9800. 3M and Scotch were also supliers. I have about 20 of these tapes, which probably date back at least 10-12 years (I don't think they are made any longer) and most have oxide layer loss problems. Therefore, I recommend the disk drive if you want to store programs with the view toward someday retrieving them. -W
