Wish me the luck, the little guy’s going under the knife… the video signal cuts out intermittently so I’m going to try changing the 16MHz oscillating crystal.

✅ Step 1 (the easy bit)

(The X1 oscillator is circled in white.)

(Did I mention I’m a nervous solderer?) :)

So mine’s apparently an Issue 4 from 1982. Although there’s a sticker in it that reads 1 Nov 83 (maybe when it was sold/serviced?)

The board’s out and yes, I was a bit of a barbarian and, since I’m not going to be using the composite out, cut the wires to it instead of desoldering them. If I ever need it, I can just connect the wires again.

Now the bit that scares me…

Right, well, oscillator replaced. No solder accidents.

Going to put it back together and try it out.

🤞

Note, if you will, the beauty of this design:

There are seven places where the power supply attaches to the main board but there’s no way you can get it wrong as the lengths of the wire won’t let you. (You still have to know black is 0v.)

Right, about to turn it back on…

If you don’t hear from me, there was probably smoke :)
