Ramworks III repair

errors_80col_s
My good old AE RamWorks III card that i had used with several Apple //e’s with the handy VGA-adapter (a2heaven.com), started to give strange graphical errors, kind of missing lines and waves when using 80-column mode. Only in the few top lines of the screen (a2osx shown here).

Luckily Mr. Plamen Vaysilov figured out quickly what could be done, small mod of soldering capasitor of 22-33pf (of any voltage) could be just soldered and get it fixed. It however took few weeks to get the part as just my local electronics supplier had IT-system issues and they were forced to close their shop… Luckily most hobbyists have other projects too so it was’t that much of a big deal, just shift of focus for other things.

But later i got the parts and i soldered 27pf capasitor as shown. Might not be the best of soldering work but it works… Yeah the legs could be.. shorter.

No more missing lines or waves.
