Hi All,
I have an old Apollo 1230 Mk II, no SCSI, single SIMM slot fitted with 32Mb, a 50Mhz 68030 and a Mach 210.
The board has a PLCC socket for a 68882FN FPU. I've bought a suitable FPU (68882FN40A - I don't believe a 50Mhz part was ever available?) from amibay and fitted this in the correct orientation.
The result? Power on and the machine sits in a reboot loop with the power/filter LED cycling between dim/bright.
Should I have to do anything else? Would a dead FPU cause the behaviour? Is this likely to be due to overclocking the 40MHz FPU to 50MHz? Anything else I can try?
I've now removed the FPU and the machine is again booting as normal.
I'm really hoping I've not wasted £20 on a dead FPU. This is after wasting £25 on a 33MHz FPU I somehow bid on mistakenly believing it to be a 40MHz part. At this rate I may as well have put the money towards a 68040 card ...
