Need pics of some CompuPro switches for project
by Richard Cini 23 Jan '21

23 Jan '21

All – I’m working on another emulation project and I’m looking for pictures of switches for the GUI. I need a power switch (both ON and OFF) and a reset switch. I saw the ones on the CompuPro 8/16 and those look nice. No rush, but if anyone has this in their collection and can snap some well-lit, clear pictures for me, I’d really appreciate it. I can re-size and clean them up. The pictures just need to be taken “head on” (no angles) as much as possible. Thanks! Rich -- Rich Cini http://cini.classiccmp.org http://altair32.classiccmp.org

Culpability and Provenance
by jsalzman＠gmail.com 18 Jan '21

18 Jan '21

Hello group, Recent discoveries brought me to post this mostly philosophical message and question about what we do as collectors when we come across data stored in or with our acquisitions. For example, I have owned my Kaypro 10 for about five years. I bought it from a fellow collector in Chicago when I was at VCF MW at the time I acquired it. Since that time, I have only powered it up about 10 times. Each time was more for just making sure its hard drive would still spin up and boot, and for poking around my only operational CP/M machine. Just recently, I decided to actually look at the files that were stored on it. It had WordStar installed, and the drive was cluttered with many files without extensions on their names. Assuming they were WordStar files, I was able to open up a number of those files. Most of them were actual Will and Testament documents for a number of people in the Chicago area around 1990. I assumed this Kaypro was once owned and used by a lawyer at that time. Another thing I discovered, and this one has some interesting impact on the device's potential provenance, was a file called RESUME. The file was a WordStar document in that it started with several lines of "dot-commands" identifying it as such. The interesting part is that it was a resume of a U.S. Robotics co-founder and V-P, as discovered in the work history listed in the resume. Yes, THE U.S. Robotics company that made the modems many of us drooled over owning back in the day. So I asked myself... why would this file be on this computer, in WordStar format, if the machine wasn't also owned by the person in question? That leads me to wonder if this Kaypro was also owned by said Founder of USR. This Kaypro may have changed hands several times before I acquired it. It's still a bit of a mystery. After all, it's not like people simply emailed files between CP/M machines as readily as we do now. Plus, someone as computer literate as a computer hardware tech founder might actually be one to write their own resume in a word processor on a CP/M system. Besides, you can certainly understand my feelings and thoughts over the potential provenance of the machine. Those two examples aside, I want to address the opinions of others about the possession of random and potentially personal data found on machines we acquire. This Kaypro has a number of Will and Testament files on it, a few legal drafts, and of course, that resume. So this brings up the philosophical discussion of culpability. Do we, as collectors of these systems, have a certain responsibility to the disposition of data found on our acquisitions? While many laws have been made over the decades governing personally identifiable information, how much of the responsibility to identify and "secure" sensitive data falls on us collectors who acquire our computers through sale or trade vs. the previous owners who decide to get rid of their computers. Before I go on any further about my thoughts, I'll end the intro of the discussion here, for others to offer their input, before I get any deeper into my thoughts on what I have and what I could/should do with it. Looking forward to your respective opinions. Jeff Salzman

Re: [vcf-midatlantic] Wanted SD card solutions for Museum
by Dean Notarnicola 17 Jan '21

Chris, You can you a Gotek with Flashfloppy firmware to substitute for Mod 1/3/4 drives (You need an expansion interface for the M1.) Though not a floppy replacement, I highly recommend the M1SE http://bartlettlabs.com/ It adds hard drive, network and other enhancements to the M1. There’s also the M3SE for the 3/4. If you don’t have a M1 expansion interface, the MIRE (same web site) adds all EI functionality. You can attach real drives, Goteks, and/or a M1SE to it.
