That's what I've been doing for the last 2 months, all centred around fixing
a PET4032. What started out as a 'well this hasn't worked since I got it in
2000, let's have a go' has turned into my living room and kitchen covered in
electronic bits as I find things I'd forgotten about while looking for
widget X or doofer Y and sources for missing/broken component Z. Add one
tick for finding a Mac Plus with leaky caps and a soon-to-explode mains
filter cap.
Then I discovered I could use a ZX Spectrum board as a 4116 RAM tester with
suitable mods for dual-boot ROMs etc so I've spent 2 weeks finding every
Spectrum I have and fixing/cleaning up the ones that have bit-rotted away
while discovering an awful lot I didn't know about these comparatively
simple playthings.
Today it's all going to come together and hopefully the outcome will be a
fully working PET4032 and an extra diagnostic tool to add to the collection.
Of course we all know something ELSE unexpected will happen.
