I have acquired three Socket 370 motherboards, marked 305 Rev0AS21, also
with part numbers 011305-101 and 011306-000.

From what I can tell these are the basis for a Deskpro SB (?) machine,
but none of them will boot! They have on-board graphics, and a memory
card marked "4Mb AIMM 133Mhz CL3" is provided for the AGP slot.

I have tried various processors and memory sticks - the LEDs on the
board light when I plug in the PS and trip the 'power on' pins, but no
boot!

By 'BOOT' do you mean " any visible power up sequence " ?
or do you have a drive in there ?

I notice that some of the pins to the panel are marked SCSI LED and
LOOPBACK - are either of these crucial to the boot sequence?

Any help appreciated!!

Do you know memory cards are good ?
If you remove memory - do you get beep code ?

The SCSI LED would just show disk activity.
"Loopback pins" This is on the front panel ? or motherboard ?
