I've created a small private mailing list for a few people (including me) who are (thinking about) building relay machines. You can get relays pretty cheap at surplus electronic shops, but that doesn't sound like a bad deal for matching new relays.... >> Hi Doug, would you mind to keep me informed ? Before turning to tube equipment, I studied relays. In my way of doing things, strict register transfer logic, a computer is no more general than a counter (on the base level), so I built two different relay counters to see how the technology feels like. It did not agree with me, so I turned to tubes. But still, I would find it quite interesting to see what you do !

Z3 builders?

>But still, I would find it quite interesting to see what you do ! I am also interested in relay driven logic. This seems to be more OT than much of the discussion here so, I'd like to see updates posted to the group. Does anyone have objections to that? Steve Robertson - <steverob(a)hotoffice.com>

Q: RL01 --> RL02 switching mods

by cfandt＠netsync.net

Hi folks, A week or so ago there was discussion of modifications to switch an RL02 drive to read (only) RL01 discpaks. I want to perform this mod to one of my RL02s as I have RL01 pacs I want to keep on hand. Could any of you provide the details to this mod? That's why I want to trade an RL01-A printset for an RL02 as seen in my previous msg. I could use a 'roadmap' to help me with this and for future repairs if needed. The SN's of the two RL02s are CX 34389 and CX 34390, if that has any relevance to the modification. Thanks for your help! Regards, Chris PS: I'm getting back into trying to get the 11/34A system up and running. I have the rack and components down in my basement shop now. (My body is still sore. That empty BA-11K and empty 6-foot rack are heavy! :) I will likely be asking a few questions as to why I wasn't able to get a bootup going last autumn and how to fix it. I'm really just a hardware newbie for now. -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.ggw.org/awa

Found today...

by black＠gco.apana.org.au

Added the following to my growing collection today : Commodore 1201 monochrome monitor ($2) works too. Triumph Adler Alphatronic PC, came with monitor, cables by the bucketload, manuals & 2 external 320k floppies. This one cost $12. It powers up with Microsoft ROM Basic 5.1, but apparently can also run CP/M, so will see what I can do with it....... it originally had a system disk as well, but that no longer exists. If you power on with no disk in the first drive, it won't work ...... What I didn't get : An old HEAVY Osbourne 8088 "portable" (sure - if you've got a crane), they've put it aside for me - next week!. An HP 85 - this one looks interesting, it has a full sized (88) key keyboard, also a tiny 5" green monitor built in, as well, it has a built in printer (dot matrix I *think*), that has a paper roll about 4" wide, not sure exactly what this thing is, anyone know ? (this also is put aside). An IBM (no model number) two internal side-by-side black 3.5" floppies, non-standard monitor connector, PS/2 style mouse & k/brd connectors, small grey box, about the width of a normal keyboard, 5" high, about 12" deep. On the rear "Manufactured by IBM Japan 1987" nothing else. And the final one, at first sight it looked like two floppy drives in a box, closer inspection showed that it was actually a PC of some description, standard RS232 & Centronics port at rear, looks like a normal 9 pin RGB connector & a k/brd connector that was 25 pins, 13 on top, 12 on bottom. Only identification was "Made in South Australia by Australian Typewriters, lisenced from Ohio Computers USA (c) 1980" They want $20 which is a little hexy for something unknown, with no manuals, or keyboard. Oh, the TA is up for grabs (in Australia) if anyone wants it for my cost price plus postage. Cheers, Lance

Cursor newsletter

by Philip.Belben＠PowerTech.co.uk

> Anyone heard of the old newsletter Cursor? Is there anyone out there > with backissues that might be persuaded to photocopy a few? I seem to recall - I was about 15 at the time so I could never afford it - Cursor was a newsletter for the Commodore PET that came on (or accompanied by) a cassette full of fun programs. Does this tally with other people's memories, or am I thinking of some'at else? Philip.

FT: RL01-A printset

by cfandt＠netsync.net

Greetings DEC gang: I need an RL02 printset. I have an extra RL01-A printset. Will anybody trade? I'll take a good xerographic copy. If a copy, I would like it kinda sized to fit in my DEC blue prinset binders with my other prinsets. Thanks much.

goodbye [was e-bay item]

by adavie＠mad.scientist.com

Enough is enough; this childish one-upmanship and thoughtless bandwidth-wasting public argument about a topic which is of little interest to me, but more to the point where neither party will ever convince the other party that they're wrong has forced me to take the plunge. I realised long ago that the only way to win these sorts of arguments is NOT TO PARTICIPATE. Thanks to everyone who has refrained from adding to the pointless debate. To the others - the only way to win is not to play. Have a think about that. I have unsubscribed, and will not see any replies unless they are directed to my personal email.
