Some of the floppies I’m recovering data look to be either a multi-part ZIP file, or something. Was this a separate product from PKZIP? I’m not sure if I have a copy of PKZIP in the stuff I’ve recovered thus far. I’ve not pulled them into DOSBOX to try and restore them, so far I’ve just tried to use Stuffit-Expander. Part of the problem is every file has the same name, just on different floppies.

Hello, I am looking for 3/16ths inch ink ribbon as used on the IBM 029
I have one lightly damaged ribbon that is entirely dry. I was told by a
typewriter restorationist that ribbon re-inking with nylon never works.
Has anyone had much success cleaning and rewetting ink ribbons? The WD40
trick on the internet seems like it would gunk up the punch mechanism.
Thanks for any information yall can provide,
I’m looking at some 3.5” floppies from about 1995, so probably about the time I got my first Mac.
Am I correct that System 7 used A:\RESOURCE.FRK\DESKTOP as the Resource Fork data? MacOS 12.5 doesn’t appear to use it. :-)
A bunch of the floppies I’m looking at have this, including ones that appear to be PC Backups.

I have 2 of these that are in need of a new home. These are quite large 4 racks each. Although the 11/60 is only a double rack by itself.
Offers. Located In Kent. WA.

I do have some Data Generals, and HP 1000's next up.

I obtained a bunch of MB (1?) cards from a fellow list member. Mostly Intel, 1 Matrox video card. Didn'y see a floppy controller anywhere, but I'll have to look closer. I have an Intel 286/20 chassis (the 20 doesn't mean mhz). Got to get me a keyboard and I'll be all set, right? O how I wish. There's an MDS keyboard on ebay, kind of pricey. Have to wonder where I'd stick the plug. No ribald suggestions please.
So apparently my future has taken a turn for the very grim. As I'll be writing device drivers from this point until my death. Yep. It's all rawhide and buffalo chips from here on out. Maybe sum yu westerners can give me a hand. Fred, Chuck, Sellam. You're all westerners and cowboys apparently. Just rustle up some docs and software for me.
I finally got around to replace the dead TO-3 power transistors in my
VR-14. They are mounted on the power supply regulator heat sink using TO-3
sockets made by AUGAT. Unfortunately one of the sockets has been broken by
somebody in the past by over-tightening the transistor mounting screws.
This may have been the root cause of the power supply failure as one
transistor was doing all the work with the second transistor's collector
lead having poor or no connection. There are two NPN transistors in
parallel to double the power which is not a very good design anyway.
I am trying to find the original Augat sockets.
Here are some links to photos showing a closeup of the socket and the
threaded insert with the originally crimped collector tab which broke out
of the bakelite socket:
I would be grateful for any help trying to source these AUGAT made TO-3
sockets. I had no luck finding stock of these with Google and Ebay.
Thanks and best regards
Museum Staff Helps Exonerate David Veney
January 19, 2023, Hunt Valley, MD — Staff members of the System Source Computer Museum recently completed a project that helped exonerate David Veney, wrongly convicted of rape in 1997. In 2005, after Mr. Veney sought a new trial, the state found irregularities in the prosecution, released Mr. Veney from prison, and declined to re-prosecute.
Maryland is one of 35 states that provides compensation for wrongly incarcerated people. But quirks in the law kept the law from applying in Mr. Veney’s case. In 2021, the Maryland law was amended, making Mr. Veney eligible for partial compensation for the nearly nine years he spent in prison. Still, Mr. Veney had not been exonerated..
In June 2022, the Computer Museum at System Source in Hunt Valley, MD, was contacted by Patrick Gilbert, Senior Assistant States Attorney and Chief of the Prosecution Integrity Unit, who asked “Can you read data from a 5.25” Floppy Disk?” Bob Roswell, curator of the museum, quickly replied “Of course!”
It wasn’t quite that simple. In theory, the diskette contained the court stenographic records from the 1992 rape trial of Grant Jones. The transcript was thought to contain evidence that would exonerate both Mr. Jones and Mr. Veney, but the printed transcripts from 1992 had been lost. Unfortunately, the diskette was neither IBM- nor Apple-compatible. It had been written on a DEC PDP-11 minicomputer using the RSX-11 Operating System. Although the museum has a PDP-11 in its collection, it had not yet been restored and could not be started. Brendan Becker, who runs the BLOOP museum inside the Computer Museum, jumped on the problem.
Brendan set up a “Greaseweazle,” a device that reads the magnetic flux transitions on the floppy disk without regard to operating systems, disk formats, or errors. The process returned a file containing long binary strings of ones and zeros. Brendan was able to decode the file structure and found that disk (despite some unreadable parts) contained the raw keystrokes that the court stenographer had recorded in the 1992 rape case using a Stenograph machine from the era. An operator of a Stenograph machine uses chords to rapidly encode conversation by creating keystrokes to represent words, syllables, and phrases. While there is some standardization, each stenographer has his/her own “theory,” which results in individual styles for different stenographers.
Luckily, Patrick Gilbert was able to obtain the services of the stenographer from the original trial (now retired). Together, they were able to substantially reconstruct the transcript from the 1992 trial, using the data provided by Brendan. The recovered transcript showed weird similarities to Mr. Veney’s case.
On March 4, 1992, Alice Arroyo claimed to have been raped while walking home from volunteering at homeless shelter. In her account, the assailant grabbed her shirt, ripped it open, and scratched her chest with his nails in a long, vertical raking motion. Ms. Arroyo provided police with a detailed description of her assailant including the jacket he was wearing. The following day Grant Jones walked into the Salisbury Police Department (in Wicomico County, MD) to report that his wallet had gone missing from the homeless shelter. Mr. Jones matched the description of the assailant, was arrested, and was convicted of assault with intent to rape.
On September 24, 1996, Salisbury Police responded to a complaint at the home of Alice Arroyo, who stated that she had been raped. Again, she provided a detailed description of the assailant and described suffering scratches on her chest in a long vertical raking motion. On October 3, 1996, David Veney, a former neighbor, was charged with rape. He was 20 years old at the time.
Mr. Veney’s first trial in April 1997 ended in a mistrial. The hung jury consisted of four jurors voting to convict and eight declaring him innocent.
In September 1997, Mr Veney was retried and found guilty of various charges, including burglary, assault, battery, and rape. He was sentenced to 25 years for rape and concurrent sentences for the other offenses.
In 2005, Mr. Veney sought a new trial on the basis of ineffective representation. (That lawyer was later disbarred.) When the State reviewed the case, substantial doubts about Mr. Veney’s guilt arose, including the eerie similarity in Ms. Arroyo’s testimony in the two cases. Mr. Veney was released from prison, and the State declined to re-prosecute.
The reconstructed transcript of Mr. Jones’ 1992 trial proved vital in establishing Mr. Veney’s innocence. On January 13, 2023, Judge Teresa Garland awarded Mr Veney approximately $730,000, along with medical, housing, and educational benefits.
The staff of the Computer Museum at System Source is proud to have played a small part in Mr. Veney’s exoneration. Bob Roswell, Curator, later learned that the state had contacted numerous other technology firms, who were unable to render assistance, before asking the Museum for assistance.
