It is a very nice machine, the only thing wrong with Further investigation shows that my estimate of 1983 was incorrect. The design of the model 320 dates from around 1985, and mine appears to have been built early in 1988. Just to keep the record straight. Philip.

Anyone have a used copy of this book?

by rcini＠email.msn.com

I'm looking for the following book. Does anyone have it? Amazon wants $80+ for it (I think that it's more of a text book than anything else). Thanks! Title: "An Introduction to the Intel Family of Microprocessors: A Hands-on Approach to Utilizing the 8088 Microprocessor" by James L. Antonakos. There are two publishing dates: 1992 and 1996.

Need Info: Sick PDP-8/f (Diode)

by mcquiggi＠sfu.ca

Hi All: I am working on a sick M8310 board from a PDP-8/f. I've found and removed a broken diode. It has a glass housing and resembles a germanium variety that I used to see often in my early days. The board has over a dozen diodes, all are the same. The diodes are not numbered but have three coloured bands: Orange, Black, Brown. Not having a suitable reference, any '8 owners out there that can tell me what kind of diode I should replace the broken one with? Thanks, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

OLD hard drives and enclosure need RESCUE!

by kyrrin2＠wizards.net

FW to: ClassicCmp(a)u.washington.edu CC: cyber(a)prismnet.com Can anyone give the hard drives and enclosures this fellow has a good home? The price is certainly right ($10 + shipping). What they are is two enclosures, each with a pair of Miniscribe 4022's (16 MB each, formatted) in them, and I've also been led to understand that the enclosures contain a SCSI-to-MFM bridge board.
