Commodore ECOs
by Richard Cini 20 Dec '20

20 Dec '20

All – I’m working on a VIC-20 project related to another project on 6502.org. I’m looking at two difference VIC-20 schematics for the “cost reduced” VIC-20 (with the drawing number 251027-01). One set is Revision C and the other D. Is there a list somewhere of the Commodore ECOs so I know what the changes are? Thanks!

O'scope went up in Smoke, I want to fix it.
by Neil Cherry 17 Dec '20

17 Dec '20

I posted this to the CDL list also, Jeff recommended I post here. Herb Johnson and Bruce Freeman gave a few useful ideas. Like don't discharge the big caps (or tube) with your fingers. :-) Here's the story so far: - I'm working on my Grant Searle 68B09 board & both weren't working (SBC now works) - Warmed up the scope and smelled burning part(s) but saw no smoke. - was able to get .2mv p-p signal and trace on scope was visible but weak - Eventually couldn't see the trace (not even with the finder) - unable to open the scope (tektronix 2336, 100Mhz, dual trace) - not even sure how - many funny screws (looking for appropriate tools or small vise grips) - On/Off switch sticks and the green flip indicator is broke. From what I've seen of other similar scopes on Youtube this thing is packed. My current guess is a video component or a power supply component. I'll be picking up the schematic next month from an online source ($15). The free stuff didn't have the scope's schematic.
