1970's TV show that taught FORTRAN ?
by Andy Meyer 24 Feb '21

24 Feb '21

Looking to settle an argument... I remember there was once a TV show that taught FORTRAN programming. This would have been the mid-1970's and I think it was broadcast over WNET channel 13 (NYC metro area PBS) in the afternoon. I can't have been the only one to have seen it, but I'm unable to find anything about it on the net. Reply to the list. TIA, Andy

RASCSI scsi emulator device
by Andrew Diller 24 Feb '21

24 Feb '21

Reading over these RASCSI devices, I decided to pick up one to see how it works with some other classic UNIX systems, where I'm currently using a SCSISD (SGI, DEC and AUX). The performance seems to be a nice boost when used with Pi4. https://github.com/akuker/RASCSI/wiki/Benchmarks It will be nice to have an intelligent alternative to the SCSISD. This device reminds me of DavidG's wonderful MFM emulator. I'm hoping that with access to a real PI doing things like imaging of drives will be much easier than it currently is. -andy

Found someone at the Toronto PET Users Group (TPUG) who is making his own Commodore PET games: https://www.masswerk.at/pet/prgs/ Some cool games. He is working on a Lode Runner Clone at the moment. It's not uploaded yet. By the way can someone point me to some 8K PET games that I can load into the museum's Original Chiclet PET computer?

Personal IRIS PSU repair
by Joseph Marlin 18 Feb '21

18 Feb '21

Hey, all. Just thought I'd reach out and bother everyone to see if there's anyone else out there who's dealt with a dead Personal IRIS PSU. Apparently they pretty much all go eventually, but I haven't been able to find anything about what the common failure modes are. Hoping there's someone with some thoughts or experience, because I'm massively a novice when it comes to power supply diagnosis.
