RetroCPU.org seems to have exhibits at the Minefaire show at the Philly Expo Center. https://www.eventbrite.com/e/minefaire-a-minecraft-fan-experience-philadelp… Sat, Oct 14, 2017, 10:00 AM – Sun, Oct 15, 2017, 5:00 PM I friend just sent some pics of kids playing games on C64's. Sorry if someone posted this already. New VPS and was having email issues this week. Seems I got kicked off of the list a few times for bounced emails. Should be back 100% now. Fingers crossed, although hotmail/ outlook.com hate me. Which is mutual actually. Henry S.

Manual card punch
by Mike Loewen 13 Oct '17

13 Oct '17

Many of you have seen the Wright Line 2600 manual card punch: http://q7.neurotica.com/Oldtech/Keypunch/wright.html ...but how many of you have seen one of these? http://q7.neurotica.com/Oldtech/Keypunch/Wright2629.html A code wheel is used to select the character to punch, and a cylinder with 12 cams selects the rows to be punched. A character wheel presses against a short inked ribbon loop to print the character on the top row of the card. You can even set tabs.

Bill, We appreciate whatever work you do to repair the TR-20! It's a hobby after all! It will be great to see it actually work instead of just looking at a static artifact!

Museum Artifact Report
by SVCatITC＠aol.com 13 Oct '17

13 Oct '17

Hello All; I figured it was time, (Since the UNIVAC Pix spread was sent by Bill D.) that I would also update us all on the progress of getting the EAI TR20 back on line. 1. Progress is slow, but moving forward on getting a decent stable reference in the test bed for doing integrator tray testing from our TR20. The test bed has to undergo some major revamp to make room for more test components to use with the main test evaluations. We are doing that revamp and fabrication here at my shops. Reference components have been purchased and now have to be installed. 2. A master 10 volt reference, to be used for setup and maintenance of the rack reference, as well as the test bed reference, has been purchased. This reference is good to better than 0.02 % error, which will be 5x better than we need for computation. 3. I still need to get out to a machine shop to fabricate the wheeled dolly for the main rack display. This will allow us to roll the rack in and out of it's berth for easy maintenance access. 4. Back lighting has been purchased for accent lighting on the TR20 while in the rack, as it will be in shadows when the XY plotter gets installed. 5. The TR20 main power supply oscillates at high frequency. Being an alumnus of EAI, I fought this problem in these supplies when working there. The solution has already been installed in the test bed, (as my supply did also osc. in the bed). I have more updated parts to install in a duplicate 10.179 supply, which will then be installed in the TR20. The original supply will be left untouched and be put "under Plexiglas" to show the workmanship to visitors. This update will also be done to the 10 volt reference in the rack and the original rack tray be put under glass as well for viewing. The work goes slow as I have had several "real job" work projects and "life stuff" that has gotten in the way of doing this fun stuff. I will try and give further updates as they move forward.

Re: [vcf-midatlantic] Considering sale of Apple Lisa...

Oh, one last thing to add, stored in cool dry basement since what? 1998 or maybe 1997.

For anyone holding their breath, it's a Lisa 2, not a 1. Oh well. Pictures here: http://wsudbrink.dyndns.org:8080/images/Lisa_Pics/ You can see close up shots of where the battery was removed. The only leak damage is very slight corrosion on some of the leads of the resistors and diodes in the immediate area. One condition note that I had forgotten is that somehow, a small hole was punched in the left shift key. This happened before I got it.

Considering sale of Apple Lisa...
by William Sudbrink 11 Oct '17

11 Oct '17

Hi All, Sorry to do this here, but I'd really rather avoid boxing and shipping if I can get this to someone relatively local. I have an Apple Lisa computer that I've been "sitting on" for a long time and I'm coming to the conclusion that I will never do it justice. It is pretty complete, including an external hard drive, printer, software diskettes and documents. When I got it, the battery was leaking. I removed the battery and did some cleanup at the time, but nothing more. I've never applied power. Drop me a private message if you are interested and I will take some pictures. Sincerely, Bill Sudbrink PS: This is a little "weird" but I will trade the Lisa for the follow group of items: 1) One of Glitch's OSI memory boards (completely populated) 2) A Jade S-100 bus probe 3) A Percom SS-50 bus graphics card (I can give you details of how to acquire this but you have to buy a complete SWTPc system (which I don't need)) --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

WTB: Large Quantity 6116 SRAMs
by systems_glitch 11 Oct '17

11 Oct '17

All, Before I spin the wheel on China relabels, does anyone have a bunch of 6116 type 2K x 8 static RAM ICs they want to sell? I have a few RAM boards that came to me with all of the SRAMs pulled, looking to try and repopulate them and get them going. Looking for 32 or more, don't care if they're used or pulls or whatever. Thanks, Jonathan
