Commodore PET 2001 Repair 

It's always good to broaden your horizons.. the museum in Cambridge has been excellent for me in this regard !

They had one of these (this exact model) at school, alongside a room full of 16K Spectrums. So I'm happy for it to be on the channel. I found it interesting. I quickly realised how similar it is to the VIC20, it's BASIC compatible and tape recordings from one will work (to a degree) on the other (also the case for the C64). This made homework interesting. The keyboard was obstructive even in 1984...

As soon as I saw 2114's i thought "Ugh... SRAM replacement time". Those things are pains in the arse and can be difficult to get hold of. The ROMs being dead didnt surprise me either. You CAN read them in a Minipro with a small adapter arrangement.. likewise you can replace them with standard 27C64's (i think) but they need a bit of adaptation. I think the Tynemouth thing you bought is a great overall solution

Gravel?! wow that's the first time I've seen that inside a computer

WYLD STALLYNS!!

I rather like the little ortholinear keyboard! It has an interesting layout, and I could imagine with a bit of practice you could whizz along typing on it. =)

What a great video!! Good to see another vintage pc get a second life :)

Now that you have it working and validated, it's time to do a second video where you restore the ram and roms. It's much better with the original bits in it, in my opinion. This one is just a little newer than mine... they're almost identical except that mine has the white ceramic ROMs in it and has the metal faceplate instead of the sticker version. (Mine is a very early one, serial #465.) Also, my heat sinks on the power supplies are different. Nice job getting her back up and running!

Excellent, got one here as well. I used a different rom/ram board though.

Great content 👏

@15:32 it looks to me like that belt is way too small. Seems that you had to stretch it far too much. Ideally you only want to stretch it about 5%. Too much tension will quickly damage the motor bearings and other pulleys. The piano keys drive mechanics are the same as the C2N but I've ordered belts from suppliers before that have been too small. The correct size should be ~9.8 to 10" (~249-254mm) circumference with a ~0.48 (1.2mm) square cross section.

How did you test ram chips? Can you share the Arduino setup? Thank you! Great content!

if only the cassette out would output a SPDIF signal compatible with any DAT machine and if only the cassette in would accept a SPDIF signal that would be decoded back into bytes you could load and save programs very quickly and if you could somehow save the title to the file you could find programs a lot easier and loading a snap.

great video, very informative as normal .. that keyboard pcb looks a bit like a mini Amstrad cpc 464 (only the original model)

Can Commodore "2001" series accept linux?
