I have an ACA1230 28Mhz and am encountering an issue I cannot seem to isolate: upon cold start, I get a corrupted screen and multiple guru meditations. After about 10 minutes leaving it powered (with the occassional crash/garbled screen), everything seems to be OK again and the Amiga works as normal. If I remove the ACA it seems to appear less, but is not completely gone. Ofcourse I took some steps to isolate/fix:
* recapped the Amiga in the whole power section (7 SMT, 2 through hole caps) and the floppy section (replacing the SMT caps), I left the two through hole caps near the CVBS out and the parallel port, plus the two SMT caps near the audio port (I did not figure they would matter in this issue)
* replaced the PSU with one from Electroware Poland
Both to no avail: is it the ACA1230 or shouldn't I have been lazy in recapping
Your input is appreciated !
