Re: Question about 1 vs 2 from Philip Lord on 2005-10-05 (lisalist1)

I have done a little more testing:

Error 57 with Parallel cable plugged in (rear port)
Will not attempt to boot from floppy with parallel cable unplugged (from rear), but no error 57. Waits on 'insert floppy' prompt. Does not see floppy
With all internal cables unplugged from HD, floppy will attempt to boot. However it is ejected very quickly. I assume It can not find the system on the disc (I can not confirm 100% if I actually have a bootable floppy)

As Tom mentioned, I think these could all be symptoms of bad power, bad drive or bad drive controller board. And as jerry mentioned, this setup was working (as is) a few years back, so It is very unlikely to be a ROM version problem, or mismatched parts ...will investigate further.

Cheers

Phil
