As Tony has pointed out, it's very easy to convert -- all the Astec and BSR SMPSUs that were used have a link you can make for 110V operation. -- Pete Peter Turnbull Dept. of Computer Science University of York

PDP-11/44 boot prompt

by hhacker＠gte.net

It is interesting that 5150 is also the numerical code attached to the process by which a person is involutarily committed to a mental ward. The first personal computer I ever saw was an IBM, though the number is not now known to me. However, it had a switch on the front which allowed for either execution of a BASIC interpreter, or execution of an APL interpreter. It was a little larger than an Osborne 1 but, its structure had a lot in common with the Osborne 1, or the Kaypro, etc. That a person does not have knowledge of a source of a "BIG IRON" machine, nor the ability to operate it has little to do with the definition of personal computer. In the early to mid 70's, I was an operator of 360 and 370 computers, and believe me, it is perfectly possible for a single operator to keep such machines in operation. William R.

Tandy 600 (was:Tandy MC5000)

Just how rare are they, and how much would one be worth? I had people trying to sell me non-working ones for $50 and over (I didn't buy them because I have a working one). Also on the topic of the 600, Does anyone have a modem cable and a printer cable for one (or a BASIC chip)? One last question... Is there any way to run non-ROM programs on the 600?

I have all of the above but I wouldn't be interested in parting with any of it. > > One last question... > Is there any way to run non-ROM programs on the 600? You could run programs from diskette. The machine has an 8086 chip in it I believe and I think there was an assembler available for it but I've never seen one. I just pulled mine from storage over the weekend and discovered that I had left the memory switch on several years ago when I put it up. Now it won't boot even under AC.

Acorn BBC Micros

On Tue, 3 Nov 1998 D. Peschel wrote> >NTSC -- smooth and flaky PAL -- flickery but more reliable > (still prone to interference, but fewer > color-related symptoms, based on my watching > Wimbledon from an old flat near Knightsbridge) For TV programmes, the flicker isn't really noticeable (though maybe it is if you're used to 60Hz NTSC pictures). The higher PAL vertical resolution and no 3:2 pulldown is better suited to films than NTSC. No hue problems on PAL either (no hue control at all). >VHF frequency bands: VHF frequency bands: >channels 2-13 ? >(1 was scrapped in short order) I think VHF has long been out of use for TV in the UK. The old VHF transmitters were turned off in 1979 (or thereabouts). >UHF frequency bands: UHF frequency bands: >channels 14-99? ? >(not sure -- little-used, many >conflicting terms and marketing) Don't know what channel numbers are used, though probably much the same as in the USA -- I managed to get a picture using my old US portable TV the other day (albeit in monochrome with no sound and slightly stretched picture). >Now, more sensible input scheme SCART which seems excellent AFAIK >on modern sets SCART is super for things like computers and game consoles, since it allows RGB input, something that apparently almost no US TVs do. >To keep this on the topic of the thread, I *am* interested in getting a BBC. >I guess I'd need a PAL monitor and a 220-volt, 50-hz power supply to run it >though. Does anyone have any ideas? Use a step-up transformer (110 to 220-240V), frequency probably irrelevant, though I'm no BBC expert. You should be able to find these in many places like Tandy/Radio Shack. You could hook the composite output up to a video monitor or TV. You might have to adjust the vertical hold and vertical size to get a decent picture. And this would be monochrome. Connect the TTL RGB o/p to a suitable monitor for colour. As long as the monitor has a v.hold control you should be able to get a stable picture. -- Mark

Classic != IBM AT

by SUPRDAVE＠aol.com

not sure about the 8533. there was a 9535 which of only a few were made which had a 90 day warranty only, and then there is the 9533 a PS/2E. very cool and although it's too new to discuss, WILL be a classic collectable. that's why i'm keeping mine and hopefully can get the one back that i gave to my brother. it was a 486slc and had one isa slot that usually had a pcmcia adaptor in it. In a message dated 98-11-05 16:31:15 EST, you write: << With nearly 40 of them here I'm sure they exist without a doubt. As for it being the last ISA, nope. There were even 386SX ISA machines in the PS/2 line, such as the 8533 (I think that was the model). The 2x, 3x and 4x models all had ISA slots. The 5x models and up were microchannel. >>

It was an ISA machine, and The HD plugged into One of you thinks the 8530 (PS/2 model 30) was an 8088, the other thinks it was an 80286. I claim you're both wrong. The model 30 was IBM's first (and to my knowledge only) machine to be based on the 8086. If I am wrong, and a 286 version did exist, no doubt flames will appear in great numbers. Philip.

cnet: "Fraud threatens auction sites"

by kaikal＠MICROSOFT.com

http://www.news.com/News/Item/0,4,28301,00.html?st.ne.fd.gif.f Extract: Online auctioneers smell a rat. Individuals who sell items over online auction sites like eBay <http://www.ebay.com/> and AuctionUniverse <http://www.auctionuniverse.com/> suspect that their bidding sessions are being artificially manipulated by phantom buyers known as "shielders" and "shills"--and that the auction sites are not doing all they can to discourage the fraud.

The 30-286 did exist. I just sold one, and have one torn apart in my basement. I *think* that they were the last ISA PS/2's. Not too sure about that, though. -Jason *********************************************** * Jason Willgruber * * (roblwill(a)usaor.net) * * * * http://members.tripod.com/general_1 * * ICQ#-1730318 * * /0\/0\ * * > Long Live the 5170! * * \___/ * ************************************************ > > One of you thinks the 8530 (PS/2 model 30) was an 8088, the other thinks it > was an 80286.
