It is indeed old. Another source of ECL (ECL10K) was RP04/5/6 disks that are definately over 10 years old and I have a bunch of 10113, 10120, 10125 and the venerable 11c90 and 95h90 divide by 10 ECL counters from the early 70s (spares for my yasu 355 350mhz frequency counter). The common voltage used was -5.2 though there were -3.2 and +2 and the other was -2 and +3.2 so the transistion voltages were near or around 0V. If memory serves the infamous Cray YMP was majorly ECL for speed. Allison

Wanted to trade a VAX 4000/200 system for a KA694 cpu

by cmcmanis＠mcmanis.com

I have a VAX 4000/200 in a very unusual rack mount BA400 series cabinet. The drives point out the front and the cards mount in the back. I do not have the 'slides' for this chassis. I would be willing to trade it for KA694 (VAX 4000/705A) CPU module. The 4000/200 includes a TK70 and a RF72 disk I believe. It takes BA400 type disk/tape cards. It has 32MB of RAM and a CXY08 async mux card. I'll pay to ship it to you on a pallet if you live near one of Forward Air's terminals. Yes, I know KA694s are sold by resellers for a lot of money, and no I don't hold out a lot of hope that someone will be interested in trading one single card for a complete system, however I had to ask. The alternative is to start selling VAXen on Ebay until I've made enough to pay for a 694. :-) [The astute will wonder how many VAXen that will take, I don't know but we just might find out...] --Chuck

National Semi 32000 ICs available

by ken＠seefried.com

I've recently come into a cache of National Semiconductor 32000 series ICs that I would be willing to part with for someone who is repairing something vintage that uses them. Contact me with what you can use and what you will use it for. The part #s are: ns32301 ns32302 ns32303 ns32081 ns16032 ns32008 ns16082 ns32082 ns32332 ns32382 BTW: If anyone has any ns32000 stuff they want to get rid of, I'd like to hear about it. Especially 32532 CPUs and 32381 FPUs. Ken Seefried, CISSP

Converting TTL monitor to Analog

by Robert_Feldman＠jdedwards.com

The Osborne 1 also used TTL-level signals for its video. -----Original Message----- From: Jeff Hellige [mailto:jhellige@earthlink.net] Sent: Thursday, May 10, 2001 3:36 PM To: classiccmp(a)classiccmp.org Subject: Re: Converting TTL monitor to Analog <snip> Looking at to references I have here, I see two monitors right off the bat that take a TTL signal as input: both the Tandy CM-1 and VM-1 monitors, not to mention the current crop of DVI LCD's out there.

ECL Logic - not ten yeas old?

by ajp166＠bellatlantic.net

What? ECL is one of the oldest logic families with ECL 1000 dating back to the 60s! I know I still have some of the old moto ECL parts. The VAX9000 (over 10 years old) was built with ECL 100k. Ove the years the threshold levels have changed some but the basic logic has been the same save for the really big thing... it's still one of the fastest.

Computer recycling

by mmcfadden＠cmh.edu

I just saw this article about computer recycling it talks about the options, seems mainly to concern PC's. Nothing about collecting or reusing, more like grind-them-up. http://news.cnet.com/news/0-1006-201-5787986-0.html?tag=tp_pr Mike mmcfadden(a)cmh.edu

I'm sorry to have gotten hopes up. I did try to move it the day before it disappeared but it is very heavy. If it's anything like it cousin, the AS/400, then it probably had battery backup built in. -- Linux Home Automation Neil Cherry ncherry(a)home.net http://members.home.net/ncherry (Text only) http://meltingpot.fortunecity.com/lightsey/52 (Graphics) http://linuxha.sourceforge.net/ (SourceForge)
