Perhaps they will show in the above quoted message, which I copied out of the digest. Bob

Unknown CDC unit , looks like a drum memory ?

by jos.dreesen＠greenmail.ch

Visited an older collector recently, and in his shed he has a strange thing, labeled CDC, that somehow looks like a drum memory, but then again not ( drum looks too small to be usefull ) The controller that goes with is? a transistor based? monster on countless small pluginboards. Pictures on? ftp://ftp.dreesen.ch/Unknown_CDC_Stuff Anyone can identify this ? Jos

Datasheet for Signetics spc16/10 ( Single chip Philips P800 processor ) ?

by jos.dreesen＠greenmail.ch

Subject says it all : anyone has datasheets for this obscure single chip Philips P800-type microprocessor ? Cant find anything but a student's report from 1981, and it is not listed in the Signetics databooks of the time ( +/- 1980) ( this is not related to the General Automation SPC16 family) Jos

Kaypro 2000 charging

by trash3＠splab.cas.neu.edu

Hi, I just found a Kaypro 2000 at the local recycler. No power supply. From what I can find online it has three(3) lead acid batteries. Any thoughts on getting it to fire up? I do not know the polarity of the power jack on the back. Once I get that, I was thinking of a 6 volt supply, more to just turn it on, rather than try to charge the batteries. Thanks. Joe Heck

ISO: DECtape controller

by derschjo＠gmail.com

I was fortunate enough to acquire a TU56 this week, along with a TD8E controller.? However, the TU56 lacks the G888 flip-chips necessary to work with the TD8E; I know these parts are in short supply, but in the unlikely event that anyone has (a) a set of 5 G888 boards, or (b) a TC01, TC08 or TC11 DECtape controller in any condition that they would be interested in selling/trading for, please drop me a line. Thanks as always! Josh

FS: PDP-11/23 + RL02

by ben＠bensinclair.com

I haven't gotten this all together yet, but thought I'd let people here know first that I have a PDP-11/23 for sale! I'm just trying to clean things out, and have decided to focus my collection a bit. I need to go down and inventory everything, but I have a PDP-11/23 with 64KW of memory (not sure on what boards I have to give it that yet). The machine itself works, thanks to some help from people on this list. I have not gotten around to getting the RL02 working, though I have the interface and what I believe is the proper cabling. It's a pretty clean drive, and does power on just fine. I boot the 11 via a TU-58 emulator, so other than the RL02 I don't have any physical drives or tapes. Not sure on the price yet, but thought I'd see if anyone is interested. Ideally this would be for pickup in Des Moines, Iowa. Thanks! -- Ben Sinclair ben at bensinclair.com

Thanks as always! Josh I have a similar problem. Has anyone re-engineered the G888?

by leolists＠seidkr.com

I have 4 AS/400s free to a good home. One is an S20, one is an 820, and 2 are 730. I also have several extra various cards, CRT consoles, cables, etc. for them. Please come get these as I have moved to a much smaller house and there is just no room for them. Private emails to leo42i[at]seidkr[dot]com Thanks! Philip
