OT: Need to borrow digital camcoder
by Jeffrey Brace 05 Jan '18

05 Jan '18

For my student teaching, I need to video record two of my lessons over the next two months or so. Does anyone have a good working digital camcorder that I can borrow? It doesn't have to be top of the line, but audio and video need to be decent for a classroom. e-mail me privately. Thanks!

Re: [vcf-midatlantic] Needed: gray metal teletype stand/table/desk
by Duane Craps 04 Jan '18

Great news! Government offices are still full of those. If you can't fit everything in, you could delete the JHU/APL I/O switching unit. I don't see where it adds much. I was hoping that it used a mini computer to route the signals to the various peripherals but, nope, That sucker is full of T-Bar relays. They were kinda neat. you can have one solenoid and stack a lot of 12PDT modules to switch as many signals as you needed. The early TARTAR Missile Systems used them to switch two 1219 computers to a 1532 Input-Output Console. Later systems used a later console with a duplexer .

New museum artifacts :)
by Evan Koblentz 04 Jan '18

We have two new additions to the museum collection, courtesy of VCFed chairman Erik Klein: a Mark-8 and a Byte Shop Byt-8, both unassembled! This is VERY exciting stuff!!! The new-to-us Mark-8 will replace our current one, which was loaned to us from David Larsen.

Needed: gray metal teletype stand/table/desk
by Evan Koblentz 03 Jan '18

03 Jan '18

Everyone, We're still looking for an appropriate desk, stand, table, etc. to use with the Univac. It needs to be metal, and ideally painted gray but we could always paint it by ourselves. Of course it needs to be strong enough to hold the 1960s teletype, but it shouldn't be too large -- we do not want a big desk there, just something maybe 2-3 ft. wide. We need this relatively soon. It should be in good condition (nothing rusted, in need of repair, etc.) and have a period 1960s look.

FS: IMSAI MPU-A rev 4 Repaired/Tested/Working
by systems_glitch 03 Jan '18

03 Jan '18

link: https://www.ebay.com/itm/273009951984 This one came in with a dead +12V regulator and a bad CPU socket. Replaced the 78L12 with a standard TO220 7812 which is less likely to have overheating problems (they run hot on an IMSAI with only a few boards installed). CPU socket replaced with a high quality machine pin socket. Fully tested in my IMSAI 8080. As always, offers welcome! Thanks, Jonathan

I'm looking for Compact Flash Cards. Does anyone have some to spare? I just got a tiny68k board and it uses a Compact Flash card. Are there adapters from Compact Flash to SD card? -- Jeff Jonas

talking to myself

Nowhere else have I found a facility with the "vintage feel" baked right in here at SDF (Super Dimension Fortress), also know as freeshell.org. SDF/Freeshell provides free UNIX shell accounts. Of course if you send them a little money, you get more privileges. For a mix of vintage feel with modern reliability, I read most of my VCF mail using the command line ssh available in the Bash shell built into Windows 10. Several email clients are available at SDF; I use Pine. Back in December, SDF suffered one of it's occasional hiccups when one of the servers ran out of disk space. Mail to my account from this list started bouncing, so the list stopped sending. I finally realized why mail from the list has not resumed. I believe I set things correctly and now need to see some traffic. Of course I could wait for someone to get bored at work and post a message, or I could send a test in the form of this message. If you read this far, you truly are a nerd worthy of participation in this list. Happy New Year, Jim
