The first thing to do is have the capacitors replaced. Thete's no point to other troubleshooting until that is taken care of. On Sunday, March 27, 2022 at 6:51:39 PM UTC-5 Nat Hall wrote: > Hi all, > > Been probably 15 years since I posted here. > > After moving last summer, I set up my long

Hi all, Been probably 15 years since I posted here. After moving last summer, I set up my long dormant/closeted IIfx that had been out of circulation for at least 10 years. To my surprise, it booted right up into OS 8.1 and my second hard drive with A/UX booted right up as well. It was a

I haven't used a IIfx, but I do know that many problems arise when the SCSI terminator is bad. If that's the problem, you have to locate a proper terminator because an industry standard SCSI terminator won't do the job in a IIfx. A lot of people end up retiring their IIfx's as museum pieces

I haven't used a IIfx, but I do know that many problems arise when the SCSI terminator is bad. Most of the models I have (about 40) don't like a terminator. There is a IIvx, a IIcx and a IIsi here - the IIfx should not be really different in its behaviour, I think. Worst case scenario is a

Actually the IIfx has a totally different SCSI thing going then any other mac II. You have to use special terminator made of pure unobtainium . Luckily I have one. Everything seems happy now that the clock is running again. WhyOSX wrote: I haven't used a IIfx, but I do know that many

I got a IIfx the other day that was running the Japanese version of 7.1. It needed its batteries replaced but, after I replaced them it seemed happy enough. Except I don't read Japanese. 64mb ram, dual floppies, 230mb Apple labeled hd, and a radius 24 bit card. I decided to wipe and reinstall
