Looking for SCSI ID select cable
by Bob Shuster 20 Aug '22

20 Aug '22

I opened an Apple Hard Disc 20SC to see why it wasn’t working properly, and discovered that the SCSI ID select cable (which connects from the drive select jumpers on the drive mechanism to a push-button mechanism on the back of the case) was missing. Obviously I can just set jumpers on the drive, but as this unit is a bear to get apart without damage I’d like to restore the functionality of the ID selector switch. Image linked below. Any chance someone has a spare or can point me to a source? It doesn’t have to specifically be from an Apple SC drive - I think these were fairly common across external SCSI devices. https://drive.google.com/file/d/1l4rgj0poQ-h8Tepce1NcM4j-EMSyWYmi/view?usp=… <https://drive.google.com/file/d/1l4rgj0poQ-h8Tepce1NcM4j-EMSyWYmi/view?usp=…> And by the way, and some of you will find this interesting, I discovered that the drive wasn’t working properly was because it had an ICD AdSCSI ST card attached - it had been repurposed as an Atari ST drive at some point! Thanks for any help! - Bob Shuster

Wang 4000 Restoration at VCF Mid-Atlantic
by Douglas Crawford 19 Aug '22

19 Aug '22

Any Wang Calculator & Computer aficionados here? We are in the beginning phase of our Wang 4000 restoration at VCF Mid-Atlantic InfoAge. On August 29th, The original Wang Programmer from Atlas Industries, the company that donated the machine will be visiting to tell us what he knows... remembers... about the machine to help us get started. The machine is not ready to be powered on, but hopefully we'll be in a good position to begin power up / restoration when we consider all the information we receive. Mark the date. There is likely to be some kind of video meeting hosted for tuning in. Details to follow. And it will also be recorded of course. Contact me off list if you have special expertise in Wang 4000 or related architecture.

RAM Test/Diagnostic ROM for Rockwell AIM-65
by Jonathan Chapman 19 Aug '22

19 Aug '22

All, Finally got some time to clean up the source for our RAM test/diagnostic ROM for the AIM-65: https://github.com/glitchwrks/aim65_memtest/ Initial work was largely done by TangentDelta. This was written to help diagnose and repair some dead AIM-65s. The test will run on a minimally functional AIM-65 -- all you need is a working CPU, ROM socket, and display board. It performs the following tests: * ROM checksum * Stack page quick write presence * Zero page quick write presence * RIOT single-pass memory test * Full system memory test The ROM checksum and stack page tests are accomplished with macros so that they can run with no RAM, since of course that might be faulty! Once the stack page passes, zero page is tested. With stack and ZP tested, the RIOT and exhaustive system memory tests are performed. These tests are more complete, since we have a minimally functional system by this point. The exhaustive test is based heavily on the routines from the OSI MEMORY TEST from OS-65D 2.0, published in OSI Small Systems Journal, Volume 1, Number 3, September 1977. Thanks, Jonathan

VCF West 2022 Report
by Jeffrey Brace 18 Aug '22

18 Aug '22

Sorry this is late. Corey and I flew there on Wed 8/3 and returned 8/8 and have been busy getting back to life responsibilities. I ran the consignment area using the new POS system that was first used at VCF East by Jeff Salzman, Alex Jaccocks, Jonthan Sturges and the consignment crew. There were some major setup problems and delays, but when I got it working it worked fantastic! Very fast checkout most of the time. Good thing because there was a line of 100 people waiting for it to open! Lots of stuff sold and lots of money came in. Corey handled the Front Desk and gave a talk as well. VCF had to switch from PayPal to Square due to shipping problems of our PayPal credit readers and due to PayPal buying iZettle and having to buy new readers. Square seems better and works well. Lots of great exhibits. I didn't have much time to look at them, but they looked fun. The talks are currently being processed and edited and should be available within a month or so. *Now for Erik Klein's Report on the show:* *===============* *For starters, I wanted to repeat that this was, by far, our biggest event ever. 11 speakers and 48 exhibitors are both records over the 25 years of the VCF.* *Beyond that, we had a great turnout with over 1,100 people enjoying the event over the course of the weekend. I'm sure Covid fears and related concerns probably shaved a bit off of that total, but it's still quite impressive.* *That is a testament to how much our hobby has grown and to how creative and compelling your exhibits and talks are.* *This event couldn't happen without your passion, commitment and support and, for all of that and all of your time and effort, I thank you!* *I'd also like to thank all of the volunteers who came out this weekend to keep things running smoothly. You looked tired by the end, but it was a happy tired, and I really appreciated all of the help you provided.* *Yeah, we definitely had a few issues with consignment. The new system is experiencing some growing pains but we learned a lot and I'm certain it will be a LOT better next year. Please accept my apologies for the lines, the waits and the other inconsistencies. Debugging is in progress.* *With this email I'm going to take a few days off from VCF, but, like you, I'll be back at it in no time.* *All the best, in vintage computing and elsewhere,* *=====================* ========================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Showrunner Vintage Computer Federation is a 501c3 charity https://vcfed.org/ <http://www.vcfed.org/> jeffrey(a)vcfed.org

The TI Mini I rescued
by Kelly Leavitt 18 Aug '22

18 Aug '22

Any interest in getting this old mini running? I'd like to work on it if there is any interest. I believe it was a TI 990/10 with a CDC fixed disk and a CDC cartridge disk. Right now, I believe it is still in the warehouse somewhere. Kelly

by Jeffrey Brace 18 Aug '22

18 Aug '22

Gloria, the executive assistant to Mike Ruane (CEO of InfoAge) sent out the following help wanted ad: "Hi All, We are pondering hiring one or possibly 2 people (to split the days) to employ as "gate watchers" on Museum days. Hours would be Wed, Sat & Sun from 12pm - 5pm every week. It would mean sitting outside by the gate on those days. During hot and cold seasons, they could utilize the guard shack and a fan or a heater. Rate of pay is $13 per hour. If you know of anyone that is interested,contact me by email. Thanks! Gloria" Contact Gloria at admsupport(a)infoage.org if you or someone that you know are interested. ========================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Showrunner Vintage Computer Federation is a 501c3 charity https://vcfed.org/ <http://www.vcfed.org/> jeffrey(a)vcfed.org

FS: AIM-65, $1 starting bid
by Jonathan Chapman 18 Aug '22

18 Aug '22

All, Finally got an AIM-65 I've been meaning to sell wrapped up and listed: https://www.ebay.com/itm/275425213541 This one was used in some industrial control application and had custom ROMs in it when I received it. It was also missing the plastic display mounting blocks, so a friend of mine measured his and 3D printed replacements. The displays were gone through and a number of bad ones replaced. The main board had to be basically entirely resocketed. The flex cables to the display board were of course crumbling, so they were replaced with two new Nomex jumpers. The printer works but has two columns which are light. I don't know if that's just that the paper I had that fit it was ancient (out of my HP 5150 thermal printer, which I don't have working yet) or if the printer is weak in those two columns. Thanks, Jonathan
