Hi, folks,
I got the Mac at a recycling shop with keyboard, mouse and nothing else.
I have formatted a single-sided disk on one of my SE30s, but do not know
how to put the system files onto it.
I'm assuming that this is now a 400 kilobyte (400 k) disk
The reset switch at the lower rear left of the case has been installed,
and it works just fine, i.e., it is not jammed on.
If I can get the system files onto my 400 k disk I will be able to
report whether the system is able to boot.
Any ideas?
Cheers,
Ian.

Hi Ian,
You may also look for a programmer switch on your Mac. This is an
image of what it looks like for a 128, 512 or Plus:

And for an SE, SE FDHD and SE/30:

Later models look like this,

They are located to the rear of the computer, along the left hand side
of the casing, near the bottom. Check also that nothing appears to be
jammed into this area or broken and pushed in.
It could be that the interrupt or programmers switch has been pressed
in and this will keep the computer in a repetitive null loop where it
is unable to complete the start up process.
Can you tell us something about the history of this Mac, please? Where
you got it, what the seller said about it, did you see it working when
you bought it. If there is nothing evident on the outside, then the
next step would be to remove the rear case to investigate further on
the inside. You'll need a long (8 inch minimum length for the shaft)
T15 Torx screwdriver to remove the screws. A 1/4" Torx bit in a holder
won't get in far enough to engage with the screws. There are very long
Torx drivers that were originally made for Macs but a regular T15 from
Home Depot, B&Q (U.K.) or a similar hardware store will be fine.
Depending on the Mac you have, you'll need to remove five (128, 512,
Plus) or four screws (later models).
cheers,
Keith
