Jonathan, Mitch at Keyways Inc (http://www.keyways.com/) has a burner and was able to help me patch my MicroVAX 2000 with the ROM necessary to support the 12MB memory board that he sold me. I had to provide the ROM image and also the shell script to split the image across the 4 individual EPROMs. Mitch has a copy and you can get the script at http://factory.jmoyer.nodomain.net/ -- I released it as public domain. Another issue, however, is that the MicroVAX 2000 support in NetBSD broke around version 4/5. I have filed a bug already (http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=56340). Kind regards, Josh/NODOMAIN.NET -----Ursprüngliche Nachricht----- Von: port-vax-owner%NetBSD.org@localhost <port-vax-owner%NetBSD.org@localhost> Im Auftrag von Jonathan Stone Gesendet: Montag, 20. September 2021 12:02 An: cctalk%classiccmp.org@localhost; port-vax%netbsd.org@localhost Betreff: Burnable, patched Microvax-2000 SCSI-boot EPROM images? I recently rescued two Microvax-2000s but both have dead RD53s. Does anyone have a ROMable image of the Microvax 2000/Vaxstation 2000 boot-PROM patches from Wolfgang Moeller at http://ftp.gwdg.de/pub/vms/pk2k/ ? I'm looking to install NetBSD, not VMS and I don't have any VMS systems on which to run PATCH. Microvax 2000 specs say it can sustain 3.3MB/s I/O, which has to be via the SCSI interface. So a SCSI emulator should be significantly higher performance than an MFM drive (either 30+ year old drive, or emulator). Web-searching shows a Sean O'Banion has burned the PROMs successfully; I haven't yet found other names. If someone is willing to burn at least one set of EPROMs for me, I'd pay for the service (either ship EPROMS, or pay for them).
