The things you have on your shelf...

This lovely old ZX81 was given to me several years ago. I never owned one originally, my dad instead saved his pennies and bought a BBC B.
I'm feeling the need to do something with it.
So if I can ask the ZX81 collective fan club hive mind, where's a good place to start with one of these?

After brief tantalum tantrums, my #apple2e is back up and running with a Big Mess o Wires "Floppy Emu".

I decided this morning I would test the #Commodore64 I got the other day and see what condition it's in. The case is in good shape. Powering the system on gave me a power LED, but no video. After putting in the deadtest cart and wiggling the switch I got a black screen, but no test screen or flashes.

The case screws are worn and after taking off the cardboard RF shield it's even more evident that someone has been inside. A couple of the failure-prone MT 4264 RAM chips have been replaced with 4164 and 8264 chips. Only one RAM chip is socketed.

I noticed U4 KERNAL ROM was getting hot, so I removed it and got a 5 flashes l, but also 2 flashes from the deadtest cart.

To do:
* Remove RAM
* Install sockets for RAM
* Install new RAM and run dead test/diag
* Replace faulty KERNAL ROM
* Bath time for case

Today's #retroComputer haul. A #Commodore16 and a "breadbin" #Commodore64. I haven't tried to power them on yet. I'm wondering if I should make a video or at least take some photos of the restoration. I've had (terrible) luck with the last few #retroComputers I've acquired working 100% correctly (not counting the RIFA caps in the BBC and IIe machines). Maybe I'll have to get the soldering iron out!
