jake18125 Posted November 17, 2020 Report Share Posted November 17, 2020 Bit of an odd one this. I was sent a 512k which was a little bit... erratic. Sometimes it will bong and flash the floppy icon, other times it will just get stuck on a corrupted screen. Thinking it was a RAM issue I took the logic board and found out that for some reason someone had removed C5 and C20 at some point (?!). I know there may be ram issues or potentially issues with the roms, but I just need to find the values for those two capacitors to rule that out as an issue! Hope you can help Quote Link to post Share on other sites
jake18125 Posted November 17, 2020 Author Report Share Posted November 17, 2020 Oh just to clarify I mean C5 and C20 on the logic board. I'm baffled why someone would of removed them! Quote Link to post Share on other sites
jake18125 Posted November 18, 2020 Author Report Share Posted November 18, 2020 Oops, C22! I need to find out what C22 is, not C20! Quote Link to post Share on other sites
dochilli Posted November 18, 2020 Report Share Posted November 18, 2020 On my logic board C22 is a 4.7uF, 35V Quote Link to post Share on other sites
