MARIAH (31.70) - My MicroVAX 3100-80 |
This post is a work in progress - notes being captured here ....
MMJ
VAX has 3 MMJ connectorsPart number for MMJ-male to MMJ-male crossover cable is BC16E
MMJ #0 connects to OPA0:
MMJ to serial adapter for connecting to PC serial port; PC serial port is male DB9 9-pin.
- MMJ female to 9-pin RS-232 DB9 female adapter: Digital part number H8571-J
Serial
VAX has one 25-Pin RS-232 DB25 Male connector- Female DB25 RS232 to female MMJ adapter part number: H8575-A. MMJ cable can be plugged into this. Other end of MMJ cable can be plugged into the H8571-J adapter for connecting to PC DB9 serial port.
Currently connected via BCC09 cable and NULL modem adpater to PC masquerading as a printer (described more further down in this post).
SCSI
The Digital StorageWorks SCSI connector is HD-50 type.Reference: https://www.lammertbies.nl/comm/cable/dec-mmj#h71j (PDF Here).

BURN ISO ON Mac OS X AT 1X or 2X SPEEDS
OpenVMS images work best when burnt to CD-R at very low speeds - 1x or 2x. On Mac OS X High Sierra, the following command line from terminal shell prompt writes an ISO image to a blank CDR at 2X speed:hdiutil burn -testburn -imagekey diskimage-class=CRawDiskImage -speed 2 Downloads/DEC\ VMS\ 5.5-2H4\ \(Jul\ 1993\)\ \[VAX\]\ \(ISO\)/VMS\ 552h4\ VAX.iso
