I dug out my old hp300 boxen. It seems one disk drive has decided to
die while on the shelf, and I don't know how long the remaining two
drives will last. Therefore, I wanted to set it up to netboot.
Unfortunately, it seems my bootroms are too old (rev A), so I'm looking
for ROM images that are netboot-capable.
I've got four machines. Unfortunately, it's not clear exactly what
models they are. They all have 68020s with 33.3333MHz crystals.
Three are more or less identical; they are one-box machines with cpu,
interface, and video; the cpu boards are marked, on the component side,
and have two 27256s for ROM code. The backplanes for these machines
have two connectors for each slot, a 96-pin one reminiscent of VME
boards and a 48-pin one that looks similar except it's the other sex
and is only half the size.
The other one is a double-box machine; it has two slots that look
identical to the other machines' slots, except that they have only the
96-pin connector, and six slots which can each take two boards (one
back-panel slot corresponds to two backplane slots); the slots use
card-edge style connectors, a la ISA or Qbus, and are either about 60
or about 120 pins, depending on whether the two sides of the card are
different. The latter boards are only about half as deep as the
former. The CPU card for this machine is one of the deep boards and
has four sockets which could possibly be for ROMs, only two of which
are occupied. The chips in them are not anything I recognize as ROMs,
though one of them is marked 23256 (among other numbers). This CPU
card is marked
I'd prefer to get the latter machine's ROMs upgraded, because it admits
to 6 MB of RAM, whereas the others have only 4. (I tried one of the
dual-connector CPU cards in the single-connector backplane's box, and
it recognized only the 4M it had in its own backplane.)
