Have to look at my Sorcerer keyboard to check some of the locations of the special characters. I have an Aquarius emulator that treats the keyboard the same way, shift-2 is the " character, etc. I've asked if I can post the source on my Sorcerer pages. On a related note, some else in the UK has just send me a copy of a DOS Sorcerer emulator he has been working on. I'd like to see about getting this on my Sorcerer pages as well. Now if I can only get some drives and CP/M for my real live Sorcerer.... ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Free VAXStations, DC area

by CLASSICCMP＠enterprise.trailing-edge.com

As I "modernize" things here, I discover that I have some surplus equipment. The following is available immediately, for free, from my basement in Bethesda MD (just barely inside the Washington DC beltway). Pickup only, fist-come-first-served: Vaxstation 3100-30, maybe 16 Megs of memory, internal RZ23 scsi disk. Comes with VR319 19" monochrome monitor, keyboard, and mouse. Vaxstation 3100-38, 24 Megs of memory, no internal SCSI disk. Comes with VR260 15" color monitor, keyboard, and mouse. The systems have been running continuously here for a couple years, and were at TRIUMF before that, and are in functional (though maybe a little dinged up) condition. Both have internal floppy drives, but I never use them, so I don't know if they work. No CD-ROM drive either, but if you bring along a 500 Meg to 1 Gig SCSI drive and buy me lunch I'll install the hobbyist OpenVMS 7.2 distribution on it for you from my CD-ROM. Also available: several DEC Rainbows, Professionals, and matching color and black-and-white monitors. Most of this stuff is in pretty ratty condition, but I believe someone could piece together at least a couple of working systems. Also comes with boxes and boxes and boxes of Rainbow documentation and software on RX50's. Drop me an E-mail (shoppa(a)trailing-edge.com) or give me a call (301-767-5917) if you're interested. Again, pickup only, I can't ship. And if you show up here and I'm in a good mood, I might try to make you take some other stuff from the basement :-). -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Need U.S. source for belt for Amstrad PCW8256 3" drive

I can't remember if anyone replied to this; is there a US equivalent of CPC, or are they a US firm?

IBM CAD system help

by aw288＠osfn.org

RCS is about to get an IBM 7361 Fastdraft CAD system - apparently an S/I based, two headed, big white box. At least that is what we think. All we know so far is that it dates to the early 1980s. Does anyone have any information on this box? Stories? Rumors? Anything? William Donzelli aw288(a)osfn.org

Java Exidy Sorcerer Emulator

by dlw＠trailingedge.com

Philip M. Scull in the UK send me a link to add to my Exidy Sorcerer pages for a Sorcerer emulator he was working on in Java. It was pretty neat. Thought I'd pass it along to everyone here. URL is: http://www.liaquay.demon.co.uk/Sorcerer Comes up in BASIC and of course I/O is limited at the moment but he's still working on it. It runs as an applet in a Java-enabled browser. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

I guess I got spoiled by working at the university and at a local electronics trade school, and then later for a small embedded systems firm. I almost always had a scope of someone else's available to use. Now I don't, and I regret not picking up a dual-trace 15 or 20mHz scope when I'd see one available, cheap, from time to time. My favorite was the Tektronix storage display scope. Now, I just try to get by using a Rat Shack logic probe and a DVM. Plenty of soldering irons (one Ungar, one generic one-piece, one Wahl), and various hand tools. A manual wire-wrap pen somewhere. A CSC bread- board. A fair selection of components, new and used. -dq

Before I started all this I woudn't have dared doing things like chip swaps, de-soldering and re-soldering components, changing drive belts and general easily-spotted repairs. Now I'll attempt apple floppy drive repair, I found and fixed a bent pin on the mobo socket that stopped the brightness control working on a Colour Classic, found blown fuses, bad connections, oxidised chip pins etc and over a few months have acquired enough tools to do most things. Though I still haven't got the right size nut spinner for my Lisa's screen mountings :) Still can't troubleshoot dead chips either. a
