Every Macintosh from the II forward (well, probably not the Classic) was
built with a ROM socket. However, the vast majority of them have ROM
chips soldered to the board, and the socket is only there for updates
which were never deemed worthwhile.
Unless you have an incredibly rare Q700, there are ROM chips soldered to
the board. They'll have a part number something like 343S0xxx or
341S0xxx and there will probably be four of them (each with its own,
probably sequential, number), although there might only be two if they
used 16 bit wide chips. I'm not sure if the Q700 is recent enough, but at
some point they moved to 44 pin PSOPs for almost all their soldered down
ROMs.
Symptom of a missing ROM would be that the machine powers up just fine and
all the drives spin up, lights come on, but there is no start-up bong and
never any video from the monitor output. If the machine fails to power
up all-together, then you have a different issue than lack of ROM.
If you have a power supply failure, the power supplies from the IIcx,
IIci, IIvi, IIvx, Q700, Centris 650, Q650, and PowerMac 7100 will work in
the Q700. It was a long-lived power supply model.

I donated 2 boxed 11/44 and several spares to a museum a few weeks ago.
They have a much better use for them than I do. The 11/44 is for me a
less interesting machine compared to my 11/70, 11/45, 11/35, 11/34 and
11/05.

======================================================================
I wonder if you could help me. I have an old Televideo 1603 (twin floppy) computer. However, I no longer have a working CP/M 86 boot disk for it.
I am based in Kingston Upon Thames in the UK, so someone this side of the pond would be my preference if that were possible.

Does anyone know what these are? I don't see anything about them in
any of my handbooks.
