Wanted all parts (excluding motherboard) for a Northstar Horizon preferably in the UK. Specifically: Any suitable S100 boards (Northstar originals if possible) Case/Chassis SA400 Floppy Drives Fortunately I can get the right PSU capacitors and a new 2 x 8v + 1 x 15v transformer wound to order. Not original but safer. Rod Smallwood

Selling Calcomp 565 plotter

by pat＠computer-refuge.org

I'm working on clearing out my warehouse, and I'm selling one of my Calcomp 565 plotters on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220550441602 It came with a load of DG Nova gear that I rescued, but I've never had the opportunity to test it out.

OT: Best Glue for Marble

by ploopster＠gmail.com

Apologies for the OT, but there seem to be quite a few people on this list who are familiar with the subject of glue. I need to attach two pieces of marble to each other. There is a tiny gap between the pieces. What would be the best glue to use for something this hard, smooth and impermeable? Peace... Sridhar

Anyone running RTE-M on an HP 21MX series M, E, or F?

They never stop: Yet another fradulent relisting of Ashley's TC11/TU55/RK05 rack

by wmaddox＠pacbell.net

He's at it again: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330411796683&ssPageName=… It's been reported to eBay, as well as to the ebay account owner and the fellow who's website was apparently hijacked to host part of the listing. I've expressed interest in buying the stuff. I wonder if he'll give me enough contact info to get him busted... --Bill

Sorcerer II progress...

by wh.sudbrink＠verizon.net

I rewired the transformer per Pete and Tony (thanks guys!) and replaced all of the electrolytic caps in the power supply. Looking at the Sorcerer One schematics and confirmed on the board, there is a big 10-watt resistor across the +5 regulator like the Altair 680 PS so I tested with the dummy load I made for the 680. All voltages were spot-on. Close examination of the logic board didn't show anything that looked bad so I hooked up a small LCD test display, held my breath and turned it on. I assumed I would get a screen full of garbage if anything, but it turns out the little display can detect and show PAL. The Sorcerer is up 100 percent. The RAM/stack report in the monitor start message indicates that the full 48K is there. I did some random poking around and the RAM looks basically functional. With my luck running this good, I went ahead and powered down and inserted the BASIC "8-track" ROM cartridge. Powered back up and there was Standard BASIC, fully operational. So, it looks like I have a lot less to do with this machine than I thought. I do want to convert the unit back to NTSC and I have not tested the serial or cassette ports though. Anyway, I'm going to do some cosmetics next. The keyboard is filthy, so a disassembly and wash is in order. Next, most of the perforated metal ventilation panels have fallen out. I have them all. It looks like they were glued in place with hot-melt glue. Is that how they were originally attached? Bill

Rather than drawing a disgram of the keycaps, wouldn't a picture taken by a digital or polaroid camera be easier and faster? Al
