Re: [vcf-midatlantic] UNIVAC 1219

20 Jul '17

Bill, Send him a link to my Yahoo! group; https://groups.yahoo.com/neo/groups/UnivacComputers/info Sounds like someone who would like to play with my 1219 emulator and assembler. Did you find out where he lives? Might be able to help, might have some old tapes. May I steal his photo for my group? I see that he was on the USS Midway. That is a museum in San Diego. I wonder if their 1219's are still intact. I was contacting them a few years ago about a video on utube with a 1540 in motion ,only to find they had replaced the reel motors with some commercial ones and had built a simulator to fake the lights. He said that the NAVY had smashed up the insides good before they turned it over. If they did the same to the 1219's , maybe I don’t want know. One of the many dead-ends looking for pubs.

Fred gave a super speedy tour to two ladies who seemed to have worked at Fort Monmouth. At least one of them had used a Wang word-processor before. There were two other groups totaling 7 people that came through with moderate interest. One guy stopped by with a picture of his father's company's Univac I from 1963. It was pretty cool. They used it for adding zip codes to mailing labels as well as stock market prediction. The name of his father's company was SysteMetrics - electronics division of Budd Company. He shared with me some photos that he had. The Univac I was bought used from Harvard University.

Workshop report
by Evan Koblentz 17 Jul '17

17 Jul '17

Bill Drom. spent all weekend working on the Univac and in particular its tape drive. Watched it soon for the first time today! Adam did warehouse things and some system testing. He helped me evaluate eight Apple //c units and one //c Plus. He can elaborate on other things that he did. Jonathan S. and I tested 18 Apple II Plus and IIe systems. Some worked immediately, some we made work by swapping components, and some need more advanced repair than we could do and/or parts we lack. Jeff B./Jeff J., feel free to comment on what you worked on.

hamful helpful handy hints
by Jeffrey Jonas 17 Jul '17

17 Jul '17

I may have mentioned this before: little plastic bags are available at BigLots and your supermarket: Hefty basics double zipper "snack portion pack". 80: 3 1/2" x 5 7/8" to a box. Very sturdy, perfect for small parts! Walmart sells smaller ziplock bags in the crafts section for beads! A workshop "must-have" for all those tiny loose parts! I just got back from the Sussex County Amateur Radio Club Inc. hamfest. The outdoor flea market is IMPRESSIVE! I did not find any treasures (no $20 Kim) but came back with all sorts of goodies from jumpers and knobs and connectors to a Nixie voltmeter. Somehow I missed catching up with Kelly, but I got to chat with Jeff Galinat (dealer with the greate location: cool breeze), Herb Johnson, Dean and not-Drew. The Saturday workshop went well: I did my project and the photos show lotsa Apple ][c,+,e being tested. Commodore stuff too! -- jeffj

Looking for schematics[pdf] - Vector Hi-Res Graphics board [S-100]
by Dan Roganti 16 Jul '17

16 Jul '17

Anyone have pdf schematics for the Vector Hi-Res Graphics board [S-100] This is from 1977, a similar design as the Dazzler but much higher resolution,256x240 Although it's not color, it does have 16 level grey scale at 128x120, I think it was a nice design. Wouldn't take much to add color with a phase delay color burst. But it relies specifically on using their own 8K memory card for the bitmap memory. Because it contains DIP ribbon cables which plug into certain IC sockets on their memory card Also looking for the owners manual too, most likely the schematics are in there too. I like to make this compatible for any 8K memory card. BTW, there's one on eB@y right now w/o manual but some of us Italians are inflicted with a case of mafundzalo ;) here's the page from the catalog http://www.classiccmp.org/dunfield/s100/vg77cat4.jpg and some closeup pics http://rogtronics.net/files/hobby/comp/vector/ Dan -- _ ____ / \__/ Scotty, We Need More Power !! \_/ _\__ Aye, Cap'n, but we've only got 80 col's !!

Looks like the same Potter Tape Drives that were used on the UNIVAC 1240 Magnetic Tape Unit. The UNIVAC generation of equipment before the 1540's at VCFed. The T-handle was to retract the tension arms mechanically rather than with a motor as the later units had.

Three retired people visited the museum today. Two of them were from Atlanta and one was local. The gentleman had been in the computer business for a number of years before retiring. He first worked for a company, then started his own company by offering PC support. He told about how things changed over the years in terms of support. His first home computer was a TRS-80. They really liked the exhibits. I told them about the VCF South East and the local lady about VCF East, the train show and the Base of Terror. I also tested some of the C64 SIDs. I think that the docents will be pleased with my selections :-D -- ======================================================== Jeff Brace ========================================================

Re: Digest, Vol 21, Issue 10 3 Phase Testing Power
by SVCatITC＠aol.com 11 Jul '17

11 Jul '17

Hi Ben; I'll put in my $0.02. Having been an industrial electrician for a couple of years back in the 1970's I might know a thing or two. I worked in a wire drawing mill where 208 Y and 480 Y 3 phase were common voltages we worked with every day. If you want to discuss more info on the project you are working on, feel free to contact me off list. My only caution is to insure safe signal return commons to the power lines you are working on, along with proper insulation of your phase line current transformers. Depending on how the power is brought into your facility, and how old the facility is, the grounds can be VERY ratty!!! Although I am not trying to volunteer him, Bill Dromgoole may be another resource to contact as he just made up a breadboard to load up the 3 phase 400 cyle MG set for the Univac targeting computer. That shipboard power was part of his "bread & butter" when he was working. Bill Inderrieden In a message dated 7/11/2017 12:02:05 P.M.

The Eagle has landed
by Mike Loewen 09 Jul '17

09 Jul '17

I recently acquired an Eagle IIE-2 CP/M computer, along with a binder containing manuals and diskettes for Spellbinder 2.30 and Ultracalc 2.0: http://q7.neurotica.com/Oldtech/Eagle/ The Eagle has single-sided, 80 track (96tpi) drives. It was missing the the CP/M / CBASIC disk, and I was able to create one from an image in Don Maslin's archive. The image was in Teledisk format (TD0), originally read on a quad-density 96tpi drive at 250kpbs. I used the TD02IMD utility to convert it to an IMD image, then used IMD with the data rate set to translate from 250kpbs to 300kpbs to write the image on a 1.2MB HD drive. Works fine.

Also find color monitors that work with them in the warehouse. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Sat, Jul 8, 2017 at 6:30 PM, Jonathan Sturges via vcf-midatlantic < vcf-midatlantic(a)lists.vintagecomputerfederation.org> wrote: > > > ---------- Forwarded message ---------- > From: Jonathan Sturges <jonathansturges(a)yahoo.com> > To: vcf-midatlantic(a)lists.vintagecomputerfederation.org > Cc: > Bcc: > Date: Sat, 8 Jul 2017 18:30:40 -0400 > Subject: July workshop: anyone need a hand? > I'm thinking of coming up for the workshop because I haven't been in > awhile, but I don't have a good project.

Very productive day!
by Evan Koblentz 09 Jul '17

09 Jul '17

Jeremy (Corey's teenage son) and I worked in the warehouse from 10am-5pm today. Jeff B. was the museum docent. Jeff and I then continued warehouse work until 9pm. Until today, half of the warehouse was orderly and sorted/organized, with the other half being a mess. Now that other half is still disorganized but it's disorganized in neat orderly aisles. :) This will please the town fire inspector (due next month, we're told) and will make it pleasant for us when we do the sorting and organizing next month. It was a pleasure to walk around that side of the warehouse tonight and have plenty of space with nothing to trip over! We also made a plan for how to proceed next time. It was a good day in the museum too: Jeff said he counted 14 visitors. Thank you Jeremy and Brace for great work today.

I'm thinking of coming up for the workshop because I haven't been in awhile, but I don't have a good project. Anyone need any assistance? Some soldering maybe? Note to Evan: I don't want to spend the whole weekend in the warehouse... :-) -Jonathan S.

OT: Favorite Pizza in InfoAge area
by Jeffrey Brace 08 Jul '17

08 Jul '17

I'm curious to see which pizza everyone likes the best. We have sampled various pizza during workshops and I'm wondering which one is preferred. This survey data will be used for future workshops after using variance and standard deviation data analyzed on a Commodore 64. If you don't remember the name, then specify when you had it. Vote for your favorite pizza: 1) Joe's 2) Dominick's 3) Vinny's 4) Anthony's 5) Carmen's (Pete and Elda's) 6) Other: (Please specify) -- ======================================================== Jeff Brace ========================================================

Funny

Stopped at a Walgreens near my home tonight. Happened to be wearing VCF hoodie. Kid behind the counter asked if VCF is a real thing or if it's just a shirt. So I explained the group. He said "yeah I do that". I asked what's the oldest computer he knows of, figuring he would say Windows 95 or something. He said "Zed X Spectrum" and even pronounced it right! Then added he's only 20. I was impressed.

Off topic-testing 3 phase power
by Ben Greenfield 08 Jul '17

08 Jul '17

Hey All, I find myself needing to verify that an outlet is supplying 16 amps at 400 volts Alternating Current at 50 Hz. I have verified the voltage with a multimeter but feel I should be more thorough. I’m trying to purchase an appropriate european socket tester which is much cheaper if not as versatile as Fluke 109-104. I also have a Tektronix 2355 which I think I could measure each line on it’s own channel to measure the voltage and the phase. Is there a safe way to measure current with this oscilloscope? Thanks, Ben

To test current, you need a load, either the thing you intend to power, or an equivalent dummy load. 400v @ 16A is going to need one hell of a big resistor. To measure current, hook up the load and then measure voltage. I = E/R. Optional extra credit: observe the waveform under load to make sure that it's sufficiently sinusoidal.

Need a single 5.25" PC floppy recovered
by John Heritage 07 Jul '17

07 Jul '17

Hey folks - I found a single floppy labeled C:\SYSOP among my Atari 8bit collection of disks, and since it really seems to be a PC floppy (I ran BBSes on the Atari 8bit, ST, then PC) as it has the hub ring and C:\ designation.. I was curious if there were someone local that I could mail the disk to that has a working 5.25" drive and could maybe see if there's anything on the disk? It's only one disk. I live near Norristown/King of Prussia PA .. I don't need the disk back afterwards.. :) john.heritage(a)gmail.com Thanks, John

Maker Faire 2017
by Evan Koblentz 04 Jul '17

04 Jul '17

We (me, Dean, Jeff B., Corey, and special thanks to Doug) came up with a plan for VCFed's World Maker Faire exhibit Sept. 23-24 in at the N.Y. Hall of Science (Queens). Our plan is to make a BASIC learning classroom. We're planning to set up four Apple //c systems (because they're small, we have several in decent condition, drives are built-in, etc.) and we'll give a formal presentation every 30 minutes. Dean is looking into using localtalk so we can print the programs for kids; Jeff is arranging the audio (wireless headset for the roving instructor (we'll take turns), small amp, couple of speakers); and I'm testing the computers (at the upcoming workshop) and writing a simple game program that shows off a dozen common BASIC commands. We will also set up a large screen so parents and curious onlookers can watch the class from behind the figurative velvet rope. We will seek additional booth volunteers. At minimum, we'll need two people in the booth at all times -- one for the welcome desk, one to be the instructor. We plan to ask specific people who we know are good at booth stuff, but everyone should feel free to volunteer. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
