Repair Workshop 3/7 & 3/8, 2020 Information
by Jeffrey Brace 05 Mar '20

05 Mar '20

We still have space in this weekend's repair workshop. As a reminder the workshop is $10 *per* person, *per* day. Sorry this is InfoAge's rule and not our decision. So that means for two days it is $20. Sign up to guarantee a table. DATE: March 7 & 8, 2020 LOCATION: InfoAge Building 9059 (CDL Hackerspace - Formerly IXR) - (2201 Marconi Road, Wall Township, NJ) TIME: Start about 10 A.M. on Saturday and ends whenever we go to sleep. End about 5 P.M. on Sunday. (Starts around 10 A.M. Sunday morning) SIGNUP: < https://docs.google.com/spreadsheets/d/1DySkGulduRUxJuPwK2RUEdP_yKD8YiDEn7K… > COST: - $10 per person, PER day. This is required by InfoAge for us to pay for renting the space. - $25 for those wanting to stay overnight (Money goes to InfoAge). Please pay ME (Jeff Brace) when you get there so that I don't forget. Credit cards accepted. I will be using VCF's PayPal Here tablet with bluetooth credit card machine. OVERNIGHT: Bring your own pillow, blankets, soap etc. We provide a bed frame and an uncovered mattress. There are showers and a kitchen for your use. - You can pay via PayPal to paypal(a)vcfed.org. or to me via cash or credit card in person. EQUIPMENT: - VCF will provide a table and you can use any available electrical outlet. - Bring your own tools, power strips, power cords, and supplies etc. - If you need particular tools that you don't know or particular parts, please post to the list for those going. They may have what you need. Let them know ahead of time. DRINKS: You should bring your own. There is a full sized refrigerator to keep them cool. FOOD: Bring your own, but we will usually order pizza or go out to eat for dinner. If the weather is nice, then we might cook burgers out back. GATE: During the hours from 1 pm to 5 pm close the front gate behind you. We want museum visitors to go to the front lobby and not wander through the middle of the campus. Outside of those times, you can feel free to leave the gate open. PARKING: Park in the main parking lot, unless you are unloading. InfoAge doesn't like us parking on the lawn anymore. QUESTIONS? Contact Jeff: 732-759-1783 jeffrey(a)vcfed.org Have fun everyone! -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey(a)vcfed.org

Re: [vcf-midatlantic] cincinatti teletype (telex model 32)
by Jeff G 04 Mar '20

04 Mar '20

Correct, Model 32 were all TELEX or TWX as far as I'm aware. If it has the rotary dial with the pushbuttons, there was a weird process for connecting via TELEX, there's youtube vids of showing the connection process. Telex lines were not normal POTS lines (took a lot of research to determine that lol) - close but not the same. Even if they supported dial-up, remember they're 5-bit 45.5baud which is odd to most computer stuff. ASR33 is much more serial compatible. I thought I-TELEX (German) was supposed to properly emulate Telex lines, but in watching a few videos I see them using the TTY keyboard to dial, so not sure if that's true anymore, as they mention something about having a hard time getting modems. On the loop, I think 20-60 seems to be the range; on my Hal ST-6 (RTTY teletype unit) it seems to sit idle at 60ma, and I think active bounces around 20ma, but you may want to verify that (as will I). >From what I recently read, 12v is usable for local and perhaps fairly short distance, but anything beyond that needs higher voltage to compensate for the inductance of the magnets. Some Navy stuff that was "Tempest" grade apparently used as little as 7v. I pipe the ITTY stream into the Hal ST-6 to let mine run, and hope that if I can rig up a better antenna someday I may even actually try RTTY through it. Would love to find a 15/19 purely for the aesthetics of them! Jeff aka Bags aka KC3GJX

DEC Rainbow 100+
by Adam Michlin 03 Mar '20

03 Mar '20

Hi Everyone, So we have an absolutely gorgeous, looking almost brand new, completely dec'ed out (see what I did there?), DEC Rainbow 100+ for hands on use in the museum now in the new business office display. It currently boots up to MS-DOS and runs the DEC WPS word processor. It also seems to have 123 installed, although there may have a copy protection issue. But what intrigues me the most is that the MS-DOS boot disk is E:... C: and D: appear to exist, but aren't MS-DOS formated. So, I'm guessing these might be CP/M partitions for the Z80 processor also in the DEC Rainbow. But, the big question, how do we tell it to boot CP/M? And, I understand it can also function as a standand alone VT-100 terminal. How do we get it to go into that mode? This opens an entirely different world of uses once it is rotated out as the "business" computer on the business desk. Oh... most importantly... I had forgotten how absolutely gorgeous smooth scroll is. Thanks much, -Adam

I'm aware of 120VDC 60mA current loops. The ASR-33 is 20mA @ 12VDC (or so). You are saying that the selector magnet in an ASR-32 pulls 60mA? -ethan

FYI, not much need to bother with the circuit boards. The meat of it (the teletype portion) is non-electronic and doesn't really depend on the boards at all. The phone part on the right was a Telex dialer, and it won't work with anything you can find today, short of possibly I-Telex. If you need help wiring, etc let me know as I have a 32 and can send pics. You'll need a loop supply capable of 60ma, which can even be a 12v supply just to shut it up while testing/running. Without a loop supply it'll chunk non-stop. Usually "proper" teletype loop supplies are around 120V DC though. Jeff G aka Bags

Jeff, I have an Exabyte 8705 drive and several Suns that support it, so I should be able to help. I have some questions however. Feel free to pass along my contact info. thanks, Jonathan
