Looking for specs for a Misubishi 82C55AP-2

iCom Attache floppy schematics

by rcini＠optonline.net

All: I bought a couple iCom 5.25" external floppy cases on eBay but they come unassembled (i.e., no internal wiring harnesses). Does anyone have a copy of the schematic that they could scan for me? Thanks.

Books

by dgy＠DakotaCom.Net

I *think* most of the books listed so far have found homes. I'm awaiting confirmation on some. I'll dig through the list to see what has NOT been requested and repost them with the other books not yet listed. Thanks! --don

Preserving cassette tapes

> Obviously MP3 would be a bad file choice :^) I beleive this came up several months ago, and MP3s at a reasonable bit rate worked fine.

DN10000s

> *were these developed in-house, or sourced from elsewhere? It was an Apollo-designed processor. My housemate at the time was at Sun, and there was much concern that it would be a SPARC-killer (Apollo was Sun's major competition up until HP killed off Apollo). > No idea why they're so rare and forgotten about They came out just before HP bought them, who proceeded to bury it in favor of HP PA.

I just reread your post. If you can post pics I should be able to ID them. When I saw white cube with 8" floppy, I was thinking tower. It's probaby an 8" floppy for a Xerox 820. The keyboard is probably a later style one for a Star.

VERY interesting phone call re: HP 9845. Can you help?

by rigdonj＠cfl.rr.com

I just got a VERY interesting phone call from the US Department Of Defense Cybercrimes division. I don't think it would be prudent to disclose the details but this MAY turn out to be VERY important. They have several HP 9845 tapes that they need to read. Can anyone help? Yes I know all the problems about the HP tapes and tape drives. I'm the one that found most of them so let's not rehash that. What I'm looking for is a working HP 9845 with a working tape drive preferably in the Washington DC area. Also information about linking a 9845 to a PC or other modernish computer so that any readable data can be transferred to a modern format. I know there's been some discussion about trying to read HP tapes on other devices. Has anyone tried to do that yet? I have several 9845s but I haven't fired up any of them in a couple of years and I know none of them have a working tape drive. I have rebuilt the drives on other HP but never bothered to in the 9845s. Joe

Sorry for all these little messages. But, if I had to type everything into one BIG message, I would just decide it was too much work and toss the whole lot in the recycling bin! :-/ I'll try to cram more into each list...
