Semi-OT: Macintosh System 7 ported TO x86 with LLM help
by Christopher Gioconda 29 Sep '25

29 Sep '25

https://hackaday.com/2025/09/29/macintosh-system-7-ported-to-x86-with-llm-h… Maybe it’s just a curiosity but I don’t see why this couldn’t work with other OS’es like AmigaOS. This wouldn’t be emulation but compiled code for hardware unintended to run it natively.

Recommended data recovery businesses
by Jeffrey Brace 29 Sep '25

29 Sep '25

VCF will sometimes get requests for data recovery. Sometimes we can accommodate them, sometimes we can’t. This is due to distance or special equipment that we don’t have set up. In the past when we couldn’t accommodate, then we would recommend Dave McGuire or Chuck G as paid services. Since Chuck had passed, we are curious to see if there’s others that anyone can recommend? Take care!

The passing of Chuck G
by Jeffrey Brace 28 Sep '25

28 Sep '25

I'm finding this out third hand and late (two months later). Chuck G was a recommended data recovery person when VCF couldn't help with recovery options. Apparently he passed away in July 2025 as stated on this post on the VCF Forum: https://forum.vcfed.org/index.php?threads/sad-news-chuck-g.1253843/ Jeff Brace VCF National Board Member Chairman & Vice President VCF East Showrunner VCF/MARCH Fundraising Manager VCF Evangelist Vintage Computer Federation is a 501c3 charity https://vcfed.org/ <http://www.vcfed.org/>

Hey! I'm sorry for not being more clear about that; I'll ask the person coordinating the event to post it somewhere. Tickets are general admission, guests can come for a single day or both. The schedule will be published closer to event with an understanding that the systems are rather old and may have issues, and the schedule may differ should we need to pivot and bring another system into the rotation. The demos of the systems do not require registration, as we are keeping the event to a limited number of tickets to ensure everyone attending can get up close with the systems we are showing off during the event. The hours are Friday 2PM-8PM and Saturday 11AM-8PM. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

by Henry S. Courbis 25 Sep '25

25 Sep '25

Hello Everyone. Quick IC programming question: I have some units of Tesla HM74S287 and 571 ICs I need programmed. About 25 units of each. Anyone with an older, or high end programmer which supports these old PROMs? I'd offer to pay postage, and something/barter/credit for your time and effort for the help. Or if someone knows of a low cost option for programming these ICs, please let me know. I know if there is a solution, our group knows for sure. Please email me direct off list unless for applicable thread discussion. Thanks! Henry S.

Tandy Assembly 2025
by Mike Loewen 23 Sep '25

23 Sep '25

Tandy Assembly is coming up next weekend in Springfield, OH: https://www.tandyassembly.com/index.html I'll be exhibiting a TRS-80 Model III with a Holmes VID-80 board and a Sprinter III speedup. The VID-80 features a 24x80 text display and 112KB of RAM. Bank switching allows running Holmes CP/M 2.2, with its huge library of software. This Model III also has a Gotek and a FreHD installed, along with a single 5-1/4" floppy drive. I'll also be showing off a LNW Research LNW-80 Model II, an enhanced TRS-80 Model I workalike. It has 96KB of RAM and a Z80A switchable between 1.77 and 4MHz. It supports up to 4 pages of hi-res video (480x192),with mono and color modes. The Model II comes with a bank switching board which suports 62K CP/M 2.2. It supports any of the TRS-80 Model I OSs, including TRSDOS 1.3, DOSPlus 3.5, MultiDOS 5.10 and LDOS 5.3.1. A dual Gotek eliminates the need for floppy disks. The built-in expansion board supports single and double-density disks, as well as double-sided and 8" disks.
