Nice, I'm glad that was the problem!

That behavior is not intentional, but it aligns with what other people have told me. There's a 5V power line on the HDMI connector that's supposed to be supplied to the HDMI sink (the monitor) by the HDMI source (us). From what I understand, the monitor isn't supposed to supply any power of its own on this line, and mine doesn't which is why I didn't discover this during testing, but it appears as if a lot of other peoples' monitors do and that backflow is keeping the 5V and 3.3V rails just alive enough to keep the OLED and a few LEDs on. Don't worry about it though; it's not going to break anything.

Who's ready for some Twiggy COBOL? "Here we go..." :D

Pretty awesome to be able to experiment with Twiggy disk images without exercising and potentially damaging the original media. Thank you, Alex!

P.S. COBOL Workshop 1.0 ESProFile 5MB drive image attached, just in case someone wants to get down like that.

At last a chance to come back from that time in 1999 when some hoser sniped me on a Cobol Workshop 1.0 auction on eBay!

And your implementation is free! He who laughs last, laughs best  :P

I know this is probably irrelevant at this point but I wanted to try one of your suggestions before I gave up on Linux.

"Try adding the line mkdir "$TMP_OFL/build" in between the git clone --depth 1 https://github.com/trabucayre/openFPGALoader.git "$TMP_OFL" and the cmake -S "$TMP_OFL" -B "$TMP_OFL/build" -DCMAKE_BUILD_TYPE=Release in the script. If that helps, then I'll add it to the official version of the script."

I did this on the version of the script posted several days ago. I get this error:

Anyway, I gave up on Linux and pulled out my MacBook Pro and ran the latest script posted last night. It was successful! Now this weekend I'll try out my Twiggy drives. Thanks again for a great device!

What did it go for back then? I wasn't buying Twiggy stuff at that time, I got my Lisa 1 around May 2002, but I did get quite a bit of Twiggy software during the mid 2000's. I may even have Cobol. I know I have Basic plus the Workshop. I also bought Fortran on Twiggy plus Xenix on Twiggy. I'll have to look and see if I have Cobol.
Has anyone archived any of those Twiggy disks that you know of?

I archived COBOL 1.0 last year, and it's available here on LisaList2. That is the first time anyone has done so and made it available to the community.

BASIC Plus 1.0 on Twiggy has yet to be archived. If you have that set of disks, we would sure love to archive those.  :)

According to the Apple Lisa - Software Release List, Fortran '77 was mentioned in a brochure as a potential Apple product but has never been seen publicly. There was, however, an SVS FORTRAN release for UniPlus+ in 1983 (by UniSoft). There may have also been an RM/FORTRAN release for UniPlus+ and XENIX by Ryan-McFarland Corp. I am not aware of any Twiggy disk archives of any of these.

Did anyone else know that this existed? I had no clue that there was ever a Twiggy Xenix release! Please archive it!!!
