I thought it might be a nice idea to bring some 8 bit British micros to VCF. Having measured my suitcase & dug out my roll of bubble wrap here's what I reckon I can bring. The machines won't be boxed but I will bring power supplies (220V) for those that won't work off a generic PSU (Dragon, QL). The BBC has a built in PSU, the electrons need 19V and the spectra 9V. I'm open to offers, either money or kit, my aim is more to defray my airfair than to make a profit. Of course, if anyone's looking for anything in particular that's more common in the UK than the USA do let me know. Best regards Rob 3 off Acorn Electrons - working 6 off Sinclair ZX Spectrum 48K rubber keys - 5 working, one with minor keyboard fault (B and N keys) 2 off Sinclair ZX Spectrum + 48K - one fully working, one with some keys not registering 2 off Dragon 32 - working 2 (or possibly 3) off Sinclair QL - all with some keys not registering. 1 off Acorn BBC Micro model B with DFS (floppy disk interface chip - less common) - working. I may be able to bring a drive as well. 1 off Cambridge Z88 Possibly 1 off Oric 1

Amusing book cover

by fmc＠reanimators.org

Moonlighting With Your Personal Computer Waxman, Robert J. World Almanac Publications, 1984 ISBN 0-345-31652-5 What's so amusing? The cover photograph is of a Fortune 32:16, and placed to the left of the title and blurb "An Insider's Advice on How You Can Earn Thousands of Extra Dollars". Oh well, I thought it was funny. -Frank McConnell

Vintage Scopes

by cmcnabb＠4mcnabb.net

Well, after the recent discussion of scopes for vintage computers, I've put together a web page with a couple of pictures of two of my scopes. One is a Kenwood SM-220 station monitor that I use with the Ham Radio stuff. The other is a Tektronix RM-503 dual channel scope that I use for troubleshooting the PDP-8/E and perepherals. In the photo, it is sitting on top of a currently non-operational Sykes 7200 Dual 8" Disk drive. Here is the URL: http://cmcnabb.cc.vt.edu/scopes.html

Favorite terminal

by mbg＠TheWorld.com

>DEC GT40. That's a PDP11/05 (with real core memory) and a VT11 vector >display board set in a desktop case with a monitor on top and a separate >keyboard). 3 user input devices -- the keyboard, a light pen and the >lights-n-switches panel. I wish I had one... I'm trying to get the hardware I need to at least put a VT11 on an 11/05 or 11/34a so I can get spacewar running... As I mentioned in a prior post, I found the DR11C which has the original spacewar control boxes we used at WPI back in the later 70s. I also found the source for the spacewar we played -- written by a friend of mine who was also a student at WPI... Megan

DEC stuff wanted..

by Fred.van.Kempen＠microwalt.nl

Hi all, Wheee.. thas been a loong weekend so far, trying to get all the piles of DEC stuff back into cabinets and in complete, working order... Then again, one can whine about that here, as we all do it, sometimes with grumbling wives and annoying kids in the dim background, but hey.. :) Anyway. Does anyone have (part of) the following items I could use to complete the 11/83 (BA123) box: - BA123 front plate saying "PDP-11/83" - mine says "MicroVAX II" - BA123 "front panel" switch set - I have one in, but kinda need two more, if they're around - *external* cable set for the tape unit - see below. I have an Emulex QT13 Pertec controller doing TSV05 emulation- runs well. However, for obvious reasons, the Cipher F880 tape drive is external, in a neat "tabletop" kind of box, even, with the two signal cables coming out and going into the back of the BA123, through one of the (now empty) faceplates. I'd like to replace that with a QT13 cab kit for BA123, and a cable I can plug into the Cipher and then into the cab kit thing, like I have for the (external) TK50 drive connected to my MicroPDP. I _know_ they exist, as I have seen them... just don't know where to look for these gadgets. Also, if anyone in Holland still has a couple of larger ESDI drives (600+ MB, similar to RA82) laying around.. pse contact me off-list.. I need one to emulate a RA82. Thanks, now back to my cabling issues here... :) --fred

(According to the sun.hardware.FAQ file.) Yes, it does. I had an SS1 and still have an SS1+ that both have 4MB SIMMs, and I've seen an SS2 with 4MB SIMMs. -- Pete Peter Turnbull Network Manager University of York

New acquisition, and question

by mbg＠TheWorld.com

Okay, it is a PDP-8/L, but I don't remember an -8/L with the kind of paddle switches this one has... I seem to remember them being the rocker kind like on a pdp-8/I Megan

Sun Sparc ID

Isn't that 96MB with a rare and expensive add-in board, and 128MB with an EVEN rarer and expensive daughter board for the rare and expensive add-in board. Zane (Sorry, I couldn't resist, but from what I've seen it's true (each of my Sparc 2's has 96MB)).
