Free Stuff (and one more)

by compoobah＠valleyimplants.com

In the off chance that someone might be able to use them, I have: 1 print head and carriage assembly 1 tractor assembly 1 drive rack (the gear type) for the printhead carriage all from a Okidata Microline 24-pin narrow-carriage printer. Also a Dell Latitude CPx LCD panel with a slightly torn connector pigtail. Personal IRIS TFLU skins - complete and a PI power supply. All in Renton, WA, but shipping should not be difficult, except perhaps for the skins. Big but light. Aha- a post-script: And The Big Boy: a Tektronix model 555 dual-beam oscilloscope, with twin dual-channel plugins (total of 4 traces!). Haven't used it in a while, so it needs a once-over before being plugged in. 110 Lbs for P/S and scope. Includes manual. No probes. It would be nice to get some sort of a trade for this.

Need help with two big Rescues

by jrkeys＠concentric.net

Great News!!! The Houston Computer Museum has been give two great collections, one in GA and one in KS. We need your help to cover travel expenses (fuel and truck rentals) for these two trips to collect these items, the estimated cost $1400 for GA and $1000 for KS (was cheaper trip but more items were added). If you can send a small or large donation to help, please send your check to our address below or go to our website www.houstoncomputermuseum.org and our donation page there to use your credit card. If just 2,400 people sent us one dollar each, we could add these wonderful items to our collections. Here's a partial listing of what is being offered: KS - SEL 810A computer, Data Control Station, Interface Cabinet, Dec LA12 printer, ASR-33 (2), manuals, software paper tapes, I/O cables, spare cards, DEC PDP 11/03, DEC 11/34, PDP manuals, and other goodies. Over 2000 lbs, so I need a 16' box truck. GA - IBM 083 card sorter, IBM 552 card interpreter (2), 029 and 129 key punches, IBM patch boards, repair parts for unit record equipment, Tektronix scope, multiple SWTP systems, and other goodies. For this load I'm looking at getting a 24' box truck. Any and all help will be greatly appreciated. Thanks John Mailing address Houston Computer Museum, 15827 Thistledew Dr., Houston, TX 77082.

Benchmark Modula-2

by Mark.Wickens＠valtech.co.uk

Hi All, Does anyone have a copy of Benchmark Modula-2 for the Amiga, originally published by Avante Garde software they could let me have? I've recently aquired an Amiga 1200 and it would be nice to use it again (from a hard disk rather than dual floppies this time!) My media has been lost in the ebbs of time, but I still have the original manual (what a fantastic one at that) and if necessary can therefore prove that a bought a copy many years ago. Is there anyone out there still using Modula-2 (or Oberon) for anything?

VOMs (WAS Re: SBC6120 (a build-it-yourself PDP-8 clone)

by compoobah＠valleyimplants.com

>sounds nice >but what is a "solid state vacuum tube" volt meter ??? > >I think it works like this--you take a 12AX7, and, using a diamond file, >carefully cut the tip off. Fill it with a good polyester resin and glue >the tip back on. Absolutely solid! Put that in your Eico! O.K. - enough already. I was in elementary school at the time. I thought I remembered them being called FETVOMs, but I figured everyone knew what a VTVM was, and since I was only pretty sure that they had FETs as their active component (it's the only type that makes sense, though), I called them "solid state VTVMs" so yes, I made that up - but I thought it would be descriptive.

OT-ish: Build-it stuff

by marvin＠rain.org

Another interesting publication for (ham) builders here in the US is QEX (published by the ARRL.) I have no idea how well known it is (I just happened to run across a copy at the ARRL table at the TRW swap meet) but I was impressed that it had some fairly technical stuff for builders that was more than some flashing LEDs. > two or three like you said. But that is still more than we have here. Nuts > and Volts is it and it is pretty basic. > > > > Billy >

OT-ish: Build-it stuff

by Billy.Pettit＠wdc.com

Tony Duell wrote: It must be really dire in the States, becasue your comments don't seem to apply to the UK that I live in. 10 years ago, we had a number of Maplin shops around the country. All they really sold were components and kits. Many a time when I was doing my Ph.D in Bristol, I'd take the bus up the Gloucester road to get some components I needed for my work. Maplin still exist, but they now sell mostly crap consumer electronics. There is a small selection of components in the catalogue, but very few of them are kept in the shops. You have to special-order them. Yes we have RS and Farnell, but they're effectively mail order only. It's not a problem to have to mail-order the main components for a project (microcontrollers, memroy, power transformers, etc). It's a right pain when you're half way through a design and find you've run out of 10k resistors :-) I live in London. In the entire London area (which I define as the bus pass zone, and is a lot larger than most people think of as London), I know of _one_ shop where I can pop in to get resistors, etc. To be fair they have a good selection of common semiconductors too, but such places are not at all common. The SU EMC directives, mis-applied by our glorious government, have effectively killed off the small kit market in the UK too. And magazines. 20 years ago there were many titles. Now I can think of 2 (Elektor and Everyday/Practical Electronics). One thing that's not helped are that ICs now come in hacker-unfriendly pacakges, and may require expensice programming software and hardware to do anything with. I can see why, I don't expect semiconductor manufacturers to cater for a very small market, but you know, it's a lot easier for the average home constructor to hand-wire 100 TTL chips in DIL pacakges than to do battle with a DGA packaed FPGA... -tony ---------------------------------------------------------------------------- ------------------------------------------------------------------------ Billy: Yes, things really suck in the US. I hit the shops around Silicon Valley and Orange County. It is a sad mix, except for one or two shops left - Weird Stuff and Halted. Nothing like ten years ago. I was in Boston in April and out on 128 and found nothing. That used to be a great place for computers and electronics. I'm probably showing my age, but when I lived in London, there were lots of nice little shops along the Edgeware Road. Another bunch were close to Paddington. I looked for them a couple of years ago and only found one open. Then were some more up near Buck and Ryan's, my number one stop whenever I go into London. What is the one place left in London? I go in to London from Colechester a few times a year. Would love to find a source of small lots. Maplin used to have a nice store in Southend, but honestly, I haven't been in it for ten years. Magazines are pretty much as you describe. I used to be able to pick up 8 or 10 different ones a month, with Wireless World being supreme. Now it's two or three like you said. But that is still more than we have here. Nuts and Volts is it and it is pretty basic. Billy

display scope options

by djg＠pdp8.net

> What options would I have for some kind of display scope for my PDP-8/e? > I have a VC8/I-like point plot controller that I built last spring and I > want a display for it. > The manuals I have list the Tek 602 (shows up on ebay cheap), Tek RM503 along with the DEC VR14. The 602 is a smallish scope size screen XYZ monitor. The 602 needs some components changed to use it (resistors and capacitors). If you need the info email me. Tek made a bunch of different models which others will probably work but don't know which specific ones. Don't know what the persistance of the 602 is. I also found a reference to using a storage monitor so picked up a Tek 611 (613 similar). It is a bigger screen. Haven't actually tried it yet though. It can be used storage or non storage. Storage tubes tended to not be very durable.

New acquisition: Powerbook 540c

by rcini＠optonline.net

All: I just got my hands on a Mac Powerbook 540c, a 68LC040 version (the last I believe). It seems to be in good condition with 12mb of RAM and a 230mb hard drive, but didn't come with any cables. So, I'm looking to accessorize a bit: I'd like a SCSI cable (HDI-30 to SCSI1 or SCSI2), more memory, and maybe a battery. If anyone has some spares/accessories they'd be willing to part with for a few $$$ and my eternal gratitude, please contact me off-list. Thanks!

OT-ish: Build-it stuff / elektor

by Billy.Pettit＠wdc.com

Tony Duell wrote: FWIW, in 1972 the UK magazine 'Practical Electronics' published a design (going over 10 issuses, I have the whole set) for a TTL-based 4-function desktop calcualtor. Not a computer, sure, but a lot of the principles were there. > Those who like to see something special should check it out : it is a > two-address machine, no instructions, but memory-mapped "functional > units". It even had hardware based multiply and divide ! I'd love to see that, but my Elektor collections starts at about the time of the first Elekturscope (and I don't have a complete run since then, alas) -tony ---------------------------------------------------------------------------- --------- Hah, I remember the PE calculator well. I actually built it, though I restructured the boards to match some proto PCBs I had. To make it easier, I copied out the articles and bound them together. I saw that binder in the last few weeks - may have it here in OC. I'll look tonight. It's not a great copy, but anyone is interested, I'll hit the Xerox at Kinko's. (I doubt there's enough interest to be worth scanning.) I have all the English editions of Elektor, but they are not easy to get to. My garage is a solid mass of books and electronics. When I retire next year, the top priority is to clean up that mess. eBay will be a full time occupation for many many months. Some of the stuff is spoken for - I've promised Al K. he can copy anything he wants before I sell it. I should probably donate all the software to the Museum, but I still don't feel positive about their permanence. Billy
