Sometimes when I switch on my SCSI-IV doesn't initialise, it may be
dirty power supply or SCSI termination issues.

Again, I'm wondering if after 12 or so years the capacitors are
degrading. I know my audio-out sounds fuzzy at high volumes.

What might be worth trying is removing all plugs, accelerators/memory
boards, ROM chips etc. and then re-sitting them. This might help a
contact either due to loosening or oxidisation.

I have no other ideas, hope a techy is reading!

Hmm...  what I would do first is open the Amiga up, give it a quick
vacuuming inside then remove the shielding and check the motherboard
revision printed on the motherboard.

This might give you a foundation with regards to finding out what
quirks your particular machine might have.

I once had a Quantum Daytona Go-Drive 2.5" and that gave me terrible
crashes, but disable the CPU cache and it worked (but everything would
overheat after a while). This was a known problem and Go-Drives are
not compatible with Amiga.

Check to see if all other hardware isn't conflicting before looking at
the motherboard. Then before you do that, check to see that there are
no visible signs of electrolyte leakage and damaged capacitors.

What about your accelerator/memory board - is this looking okay?

It may be cheaper to get a new Amiga on eBay rather than pay £30+ for
a chip replacement. Try the basic damage location test first and let
us know what other stuff you have on the machine (ROMs too!).

Just another thought, you're not overloading the standard vanilla
power brick are you? No extra floppy drives, '030 or hard disk?

What about your power strip, it doesn't have a washing machine, oven
and cement mixer on it right?

:-D :-D

Yeah, the memory could be the fault if it's an expanded Amiga but
since SIMMs are solid state how often do they burn out?

I know that since swapping my EDO for FPM I don't crash half as much
but this problem sounds different.

When you think of the ways data degrades in hard disk platters,
floppies and CDRs... makes you wonder if we don't keep moving our
software onto the latest mediums then it will eventually trickle away!

:-o
