πΊπΈ Commodore VIC-20 Refurbish: Part 1
25Saw this VIC for a pretty good price - three broken keys. Thought it might ... might ... make for an interesting video series. Let's see. It doesn't appear to work at the moment, so some work required. It's a US/NTSC model with 6560 VIC, serial no. P896270.
It's an original 9VAC two-prong plug model (my preferred as they're easy to power) - I simply use an IEC C7 type plug ("figure 8") and put a 2.1mm socket on the other end so I can power it by a 9V (AC or DC) plugpack or bench supply. No need for a stupid dual 5VDC/9VAC power supply,
Tasks to do:
[1] Clean the case & keyboard
[2] Fix the keyboard
[3] Fix the on/off switch [done] - actually, replace it
[4] Make improvements to the board - 65C22, modern regulator
[5] Oh, fix the problems, if possible
To be continued ...
