Pretty amazing stuff. Thanks. Yes, that is the same sort of thing. One difference (perhaps an improvement) in the Genrad digit-display modules is that the grain-of-wheat bulbs are just slid into tubes in the back of the module -- their contacts poke out the back of the module and mate up with spring-loaded contacts in the display chassis. Also, the modules slide out from the front of the unit, so replacing the bulbs is fairly straightforward and can be done without soldering. -Frank McConnell

Just a quick additonal classiccomp-related Electra/P3 note

by xds_sigma7＠hotmail.com

I just thought that the group might find it interesting to know that the P-3 Orion carries, as part of the electronics suite, a Data General Nova 3. Nifty, isn't it? Just in case anyone thinks I'm talking about the avionics, I'll go ahead and say that I mean the Nova 3 is part of the ASW suite.. Oh yeah, ASW = Anti-Submarine Warfare, which is the Orion's primary function, though it also serves as an all-purpose patrol aircraft, and it can even carry out anti-ship missions (it has underwing hardpoints for Harpoon cruise missles). At least I seem to remember that it was Harpoons it could carry, at any rate, it is capable of carrying some sort of missiles ;p Will J _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

It was a custom circuit but the circuit was a 4bit microprocessor that HP did for their own use. Bell labs also had a really interesting 4bitter they used in ESS (early). Allison

Old tandy 1000 keyboard 8 pin din pinout?

by ajp166＠bellatlantic.net

From: Don Maslin <donm(a)cts.com> >Was the pinout different, Allison? I have both the LB-186 and >LB/PC. The LB-186 is PLCC, while the LB/PC (V40) is SMT, but both look >to have a like number of contacts. > - don Not all the same pin functions. Some internal differences, V40 has async serial IO for example. Nicer part. Allison

system/36 awefully quiet...

by mcguire＠neurotica.com

Sounds like 220v 2-phase. Two hots and one neutral/ground. If its marked 20A, I believe the connector is probably an L6-20 twist-lok. Not difficult to wire up in most US homes. My computer room is running from two APC Matrix 5000 5kva UPSs, which have 220v inputs and 110/220v outputs. I ran two 30A 220V (L6-30 twist-lok) circuits from the two outer poles on my breaker panel to power the UPSs, and everything (be it 110v like the regular Alphas/Suns/SGIs and such or 220v for the Crays) runs from the UPSs. Having the equipment run from dedicated 220v 2-pole breakers is very, very nice. Definitely worth the trouble. -Dave McGuire On October 31, Merle K.

RML LINK 480Z with network connection

by celigne＠tinyworld.co.uk

I've just acquired another 480Z, but this one powers up with the words "Z-NET Firmware Vers 1.1q", and there is a BNC connector on the back. Would I be right in thinking that this is a Research Machines proprietary network? The other good news is that I've got a working 5.25" disk drive with it, and a single disk, for an educational Viking game. (I thought that the machine dated from 1984, but perhaps I'm a thousand years out). Instead of typing "R" to run BASIC from ROM, you can type "B", and it boots CP/M >from disk, loads another version of BASIC, and then runs the game. I can then exit the game and use CP/M, which is something I've not done for 15 years. Oddly enough, the 480Z talks to the disk drive through the serial port. The disk drive also contains another serial port, which I've yet to experiment with. As with my other 480Z, the high resolution graphics only displays in black and white on a television. I've still not made up a monitor cable, despite asking for (and getting) the TTL RGB pinouts many months ago, so I don't know whether it will produce a colour display at all.

Computer LCD projection panels

by mrbill＠mrbill.net

I picked up a Sharp QA-25 computer LCD projection panel from a local junk shop today. The glass/"optics" look just fine (no scratches, just needs to be Windexed), but I have no manual or power supply or data cables for this. I remember using one about 10 years ago when in school, but I dont remember if this uses EGA or CGA inputs (has a 9-pin D-shell data input). I'm guessing probably CGA; anybody know specifics on the data cable? Think I can hook it via straight-9pin-cable to the CGA out port on the back of a laptop and fire it up? (fortunately I can use a standard generic wall-wart power supply; it has the specs and connector diagram on the side of the unit). Now, off to the office surplus store to get an overhead projector for $10.... Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

OT?: NeXTstation color with *all* accessories--what's it worth?

by MTPro＠aol.com

In a message dated 9/18/00 1:14:52 PM, swperk(a)earthlink.net writes: << I have no idea what something like this is now worth, so any and all advice is appreciated! >> Hi Stan, well, of course eBay is always a gauge of what classic computers are actually selling for (even if some "collectors" on this list are negative about it). Take a look at what they are selling for there. Here is a helpful link to take you right there - http://search-completed.ebay.com/cgi-bin/texis/ebaycomplete/results.html?de… &cobrandpartner=x&ht=&maxRecordsPerPage=50&query=%28next+cube%2Cnextstation%2C next+computer%2Cnextstep%2Copenstep%29&SortProperty=MetaEndSort&SortOrder=%5Bd %5D After you've reviewed what they've been selling for over the last thirty days, click on the "Search Active Items" link near "Sort by" area to see what they are selling for now. I have many links already setup for eBay to search for specific computer types.

Need to sell out?

by SUPRDAVE＠aol.com

Apple collectors/users are selling out? harrrumph, can you quantify this? Every computer collector runs out of time and space, I know I do! Since you offer to buy apple stuff, let's see a price list of what you want to buy. I've a room full of apple goodies and enough duplicates to sell. How much money you have?
