It seems like anything that can display a PAL signal will do.

Justin, Yes, that’s perfect. It has composite and RF and will almost assuredly do PAL.

I haven’t bugged this list in a while but wanted to remind everyone that we still do monthly Trash Talks. We’re doing one on Saturday at 5pm and you are all invited to join. Just email me and I’ll send you the invite to the Zoom meeting. You can also just watch on YouTube but it’s way more fun to join the interactive meeting imho. I’m going to talk about my Model II Boards Collection VCFE exhibit this time. https://www.youtube.com/@TRS80TrashTalk TRS-80 Trash Talk youtube.com I'm looking forward to seeing everyone at VCFE! Take care, Pete

older computers to sell
by bear 17 Jan '24

17 Jan '24

I have come to the point in my hobbies where I need to admit I am not going to have time to fix or repair many of the older computers that I have collected over the 45 years of being both a hobbyist and a professional in this space. To that end, is there an appropriate place for me to list the vintage gear I have for sale or trade? -- Bear bear42(a)gmail.com (email) PGP Fingerprint = 9996 719F 973D B11B E111 D770 9331 E822 40B3 CD29

Re: [vcf-midatlantic] Niklaus Wirth passed away
by Jeffrey Jonas 17 Jan '24

I usually ignore linkedin notifications. This is one I wish I had noticed on Jan 3. Liendo noted Wirth's creation of Pascal. This notes Modula-2 and Oberon: Computer History Museum <https://www.linkedin.com/company/computer-history-museum/?miniCompanyUrn=ur…> In Memoriam: Remembering Niklaus Emil Wirth It is with deep sadness that we mourn the passing of Niklaus Emil Wirth, a pioneering Swiss computer scientist and esteemed 2004 CHM Fellow. Niklaus Wirth made incredible contributions to the world of computing, leaving an enduring legacy that shaped the industry. From the creation of Pascal in 1970 to Modula-2 in 1979 and Oberon in 1988, his programming languages influenced generations of students and professionals. Wirth, a recipient of the ACM Turing Award in 1984, was not only an inspiration in programming languages but also delved into the hardware and software of computer design. His impact resonates in the foundations of structured programming and software engineering. Please take a moment to honor and remember the life and work of Niklaus Wirth.

Re: [vcf-midatlantic] Does anyone know the substitute germanium transistor for a B1182

Good point, I’ll just recap the monitor board then and start from there. If the transistors seem bad, I’ll bring the board to either the SystemSource workshop at the end of this month or the VCF one at the beginning of March.

It’s a different package and I think in a lot of cases you can’t swap out germanium for silicon in older circuits so I’d prefer to stay with germanium.

01/20/2024 - the plan is to migrate the Hotel administration area to the Camp Evans network. This will eliminate the last of the main post cable modems, saving $1400.00 + a year. This includes attic work, along with running wire mold in the admin area for the new network drops. The plan is to start around 9:00 AM and wrap by 2:00 PM on 01/20/2024. Please reply off-list if you intent to participate... Martin
