M9312 boot roms (again)

Sorry, I never bothered making or downloading those ROM images. I must admit that it would be a nice addition to the M9312 page that I have put in the PDP-11/34 folder ... if Pete gets his hard disk data recovered (or read the PROMs again), I will gladly add that to my site (if Pete does not object). As proven last week: some copies of the stuff at several sites may not be such a luxury as first thought of ... - Henk, PA8PDP. -----Original Message----- From: cctalk-bounces(a)classiccmp.org To: General Discussion: On-Topic and Off-Topic Posts Sent: 4-12-2004 13:29 Subject: Re: M9312 boot roms (again) On Nov 27 2004, 23:01, Wai-Sun Chia wrote: 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. 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. -- Pete Peter Turnbull Network Manager University of York
