I received this email, in case anyone's interested in these systems. The DataPoint is not the earliest 2200 system.

mainframes and other stuff

There are 12 troy ounces to the pound, not 16. Anyway, yes, you are talking about something like 4800 PPros equivalent. Now compare the plated surface areas of a PPro compared to a number of the pins on the backplane - you will find that a gold plate area on a PPro (mind you, there is a fair amount under the cover, too) equates to a surprisingly small amount of old IBM backplane pins. Remember, the pins are long, and plated on four sides - and probably had a thicker plate that on PPros. And yes, the 75 was a really huge machine. Gold on the backplanes, gold on the connectors (early Bus&Tags have a very heavy plate), gold in transistors. I would not be surprised if there was gold in the lamp sockets. -- Will

Alpha and VAX Available in Sweden

by pontus＠Update.UU.SE

Hi all I need to free up some space for new interesting things comming in. So after much thinking I'm letting these machines go: VAX 11/750 (Complete, some spares, needs love) Alphaserver 1000 4/233 (Broken PSU) Alphaserver 2100 5/300 (Deskside, one CPU) Alphaserver 8200 5/300 (fullsize rack: http://www.pdp8.se/bild/sthlm_haul/as8200.jpg) DEC 4000 AXP (http://www.pdp8.se/bild/sthlm_haul/axps_small.jpg) One caveat: I don't need all that space, so if the 11/750 goes the AS8200 can stay. The things are free if you pick them up. But I'm flexible when it comes to shipping but make me an offer that makes it worth it to me. Trades for smaller things or things with blinkenlights are welcome. I'm also selling Two MicroVAX 3500 in BA213 with two DSSI disk cabinets (R215F). Timeframe: I'd really like the things gone before March next year but I'm flexible here also. /P

Who's rewired their house for this hobby?

I don't know the reasoning for Germany, but in my town in Norway it was apparently used in order to reduce costs, actually. Traditionally 3-phase in Norway has been distributed with 3, not 4 wires: If balanced, earth return current is zero. Some years ago the Norwegian system was unified with what's standard in most of EU, I'm not sure if things changed then (but at least in the past there was no 'neutral' and 'live' in a home - both wires were equal in that respect, and the voltage to earth was never 220V (as we used back then, now it's 230V), it could vary but was in practice never more than 160V, normally just 120V. Less of a jolt than if you touched both wires. Wire to earth accidents is a much more common affair than wire-to-wire accidents). Anyway, I'm not an expert on this so as I said I'm not certain if the policy of using only 3 wires has changed - but at least with that system, distributing 3-phase means that you could transport 200% more effect with only one additional wire. Even with four wires it pays off. And that's why it was done AFAIK. [In addition it seems that feeding 3-phase all the way to the consumer is nearly 'free' with TN, see below] (Reading up on this a bit - apparently the traditional Norwegian power distribution system was called 'IT', Isolated Terra, while new and refurbished areas are now using TN, Terra Neutral (400V), the system which is now common in Europe. What impact this has for the jolt when you touch the wire I'm not sure about [update: Ouch, you'll get 230V to earth], but apparently TN is what makes it feasible to distribute 3-phase to every house. With the older IT system the (then) 3-phase 380V system had to be installed separately. With TN you get both 230V and 400V directly available for the consumer. But I think you'll need 4 wires in practice. It still pays off, economically.] Now I slowly retract my steps back to the more familiar lower-voltage DC land where I feel on more solid ground.. :-) -Tor

i wish I could even get back on the digest, I followed the instructions and it didn't work, none of the commands to the listsreve worked other than the 'help' one, I'm getting a ton of emails and need to get back to digest.

Digest Size?

by earl＠baugh.org

I get CC talk in a digest form and just recently the size per digest is crossing the boundary where GMail will "chop" the end of the digest. This seems to be a recent occurrence...so wondering, is this something Jay would need to change, or is this something I can change? I didn't see where I could change it (maybe I'm just missing the setting...or misinterpreting something...) Earl

Anyone Near Los Gatos, CAL? $$ for Serial Printer Repair

by billdeg＠buzz1.com

$$ Printer Repair in Los Gatos, CA $$ Anyone in Los Gatos CA area looking for an emergency repair job? I was contacted by a travel agency who needs their Texas Instruments RO 810 printer repaired. The problem is that the printer does not respond to prints sent to it, although the lights are all normal indicating READY. They're using the Apollo system but I don't know what kind of computer or terminal they have hooked up to the printer. The RO 810 is just a receive only serial printer, essentially a one way serial terminal, probably 300-1200 baud. Here is a photo of the same printer I own. I have the manuals, etc. Probably they're also on the web http://vintagecomputer.net/cromemco/system_three/ti_omni_800_810_RO_Terminal .jpg Anyone want to take a stab at it? I can help remotely but I live 3000 miles away. Agency has a backup printer that might work, need someone on site to set up and or swap parts. IF YOU CAN GO TO CUSTOMER SITE (ideally 11/26 or Monday after Thanksgiving), please contact me via vintagecomputer.net/contact.cfm. I will pay whomever helps me as a subcontractor and will assist you by phone as needed. Because I have same printer I can help run compare/contrast testing. Note that printer ribbons for the TI RO 810 and Decwriter II are interchangeable. Bill Vintagecomputer.net/contact.cfm
