Hello,
Sorry to beat this old horse again, but did anybody set up a
repository for M9312 boot images since the last discussion?
(I actually went to look for them in www.classiccmp.org/M9312, and
Pete's DECROM repository doesn't seem to have the 23-xxxA9 M9312
roms)
I need some of them, specifically the DU, DX, and DY.
Henk may have (http://www.pdp-11.nl/index.html), but maybe not online.
I have a few on a local disk. Ah, spit, that's the one that crashed a
few months ago, and I've not wired up the programmer again yet, so I
have some ROMs but not the images. The ones you want are:
23-753A9 RX01 DX Boot ROM
23-757A9 UDA50 DU Boot ROM } I'm not sure if both are
23-767A9 UDA50/RAxx DU Boot ROM } correct -- see below
23-811A9 RX02 DY Boot ROM
I have at least one of each of these, except the 23-767A9. I probably
have that number in the list because it's been listed somewhere with
that description, but since I have two 23-757A9 and no 23-767A9, I
wonder if the 767 is a typo? Or is the "DU" against 757 meant to be
"TU"?
I'll host the images if no-one already has.
Question:
Is the DY (supposed for RX02) able to boot RX01s too?
If you mean boot from RX01 drives, no, the bootstraps are different.
If you mean boot from an RX01 diskette in an RX02 drive, yes, it
should work, though depending on the OS, the diskette may need a DY
boot block.
