TI-74 Basicalc

[Leviset]

GRSBANKS - the Link in Didier’s response is awesome and has a large number of really useful manuals. I haven’t got a TI-74 but I recently got a fully working TI-95 Procalc with an 8KB memory module. I’d already got another TI-95 Procalc that nobody has managed to get to show any signs of life; there’s a new repair shop opened up here in Sheffield UK called iStop Repair. The 2 guys who run it (Cal & Jason) are fully fledged ex Apple Engineers and have started up their first business repairing electronics, mostly Apple & PCs, but they’ll have a go at anything. Someone gave me a 2011 MacBook Pro that had the (not) well known “GPU nVidia let’s see if we can get away with using less solder on the graphics card” which caused over a million units having to be recalled to be rectified. I understand one of the first Apple quick fixes was to ‘bake’ the Motherboard in the oven at 375⁰ F. This worked for some but then the GPU failed again after just 3 months. Apple kept this issue well under the radar - I know this all how? I bought a secondhand 2009 MacBook Pro that had exactly the same issues, but being past the 4 year deadline Apple insisted on meant I had to pay (an independent Apple repair guy) £300 to fix it. He baked it and then put a new GPU in 3 months later when it failed again.
Anyway I digress - I gave iStop Repair this old 2011 MBP to use for parts. A couple of weeks after they’d tried to fix my TI-95 they rang me. Completely unsolicited they’d spotted a working TI-95 on TAS and just bought it. When it arrived they GAVE it to me no charge - it’s renewed my faith back in (some of) the Human Race!
