Does anybody know of anything interesting places to visit for CC type items in the Los Vegas area? A friend of mine will be visiting out there for a couple of weeks and wants to see what he can find. Since Nellis AFB and Groom Lake are close by are near by I'd think there would be some good scrap in the area. Joe

11/45 pictures & questions

by jwest＠classiccmp.org

I couldn't wait, had to get the 11/45 off the trailer and dig around in it. Upon first close inspection, the thing is FILTHY. It will take some very major cleaning before attempting to do anything with it. However, from a first looksee - it definitely doesn't look "beyond all recall", it looks like it will clean up nicely. While very dirty, I can't see any rust anywhere. Good sign. Some pictures are at http://www.ezwind.net/jwest/1145 Questions... There is a separate power supply at the back top of the rack, which powers a DEC brand backplane mounted "pins forward" in the front. There's also some lights & switches here. There's some flipchips in it, and lots of what look to be D/A cards. Does anyone have any clue what this was used for? I took extra pictures of this part - tried different focus settings & all so hopefully some will be clear. Looks like the machine has no FP option, and 8K of core memory. I haven't decided what OS I want to run on this thing yet, maybe RT11, or RSTS, but I was really hoping to run 2.9BSD or Unix 7 or some flavor of unix. That's not gonna happen with 8K of core. I have some RL02's I could put on it. Anyone want to trade the bits to make it use semiconductor memory in exchange for the core backplane and core boards? Is FP required for anything I've mentioned? I'll get it up and running on 8K to test & refurb, but definitely want to go the semiconductor memory route so I can run one of the above O/S's. Hey, can this thing use any of the memory boards I have in my 11/44? Thanks for any advice! Jay West

I agree with Fred, although the Beeb uses an Adaptec ACB4000 and in theory you might be able to hook the drive+ACB4000 up to a PC with a SCSI bus. However, you still have the problem of understanding the data. Stick to kermit. -- Pete Peter Turnbull Network Manager University of York

Mystery emulex unibis card

Yes, it's a comms card for unibus (CU). It's like a bigger version of a DZ11, ie a serial port multiplexer. Unfortunately you also need the panel(s) that goes with it, because some of the serial interfacing is on the panel. -- Pete Peter Turnbull Network Manager University of York

Mystery emulex unibis card

by TRASH3＠splab.cas.neu.edu

In all of my Emulex documentation, (plus past experience) makes me believe it is a communication controller, as the "c" series were comm devices, and usually it would be a CU11, but I can only find cc11 and cs11 devices in my emulex books. "S" devices were usually disk related, and "T" were tape. Joe Heck I could be mistaken...

Reply-to: kml(a)metrocast.net ---------- Forwarded message ---------- Date: Mon, 29 Dec 2003 08:15:49 -0500 From: Dan Morgan <kml(a)metrocast.net> To: vcf(a)vintage.org Subject: HP150 stuff Hello, I have a small van full of various HP150 etc to give away to anyone or anyorg that wants such. Includes HP150s, Harddrives, floppy drives, printers, portables hp100s, software etc, etc. Hate to see this stuff go off to the landfill if somebody can use/preserve it. Most all of it works, We are still using an HP150-two with an impact printer. Would dearly like to find replacement ribbons for the printer to keep that one on line. Any help there? Otherwise the rest can go. I'm located in NH.

MFM PC/XT HDD Controler

by classiccmp.org＠irrelevant.fsnet.co.uk

Spotted this on a UK auction site: http://sumo.ebid.co.uk/perl/objects/auction.cgi?auction=1067709373-87555-0&… Terrible description, though something of a bargain. (Seller has a few other old bits too.) But made me think, following on from a discussion of floppy formats recently, I have an old ST506 style 10Mb HDD buried in the cupboard for my BBC Micro system. Now I can't remember if it's got ADFS on it or an Econet server partition, but probably the latter - are there any tools out there that could read this if I hook it up to a PC, or am I best just connecting it back to a Beeb and kermit'ing it all over?

OT: new info on fuse

[hack...] There is a chance that after sitting all that time the filter cap has become unpolarized. Every time you turn the thing on the current surge required to charge the cap will blow a fast blow. What you might try is to get a variac, turn it down all the way, attach the laserdisk, turn it on and then slowly bring the variac to the full voltage. This will give the cap a chance to repolarize without pulling too much current. If the fuse still blows you probably blew the input rectifier or something else expensive... CRC

getting trs-80 basic programs into pc text files (hp2000 prog rams)

I took hp basic programs, downloaded them into my trs-80 (saved them as basic code..of course it wouldn't run on the trs-80, but the trs-80 would hold the code just fine)...these are on cassette. I know that several emulators for the trs-80 can take cassette input..what I'm looking for is a path to get the programs loaded from cassette with the final destination being a pc text file which I can then easily upload into my virtual hp-2000.
