That's the part number you (used to) order from DEC - what the firmware
says is likely to be extremely different :-)

From the Ultrix /sys/data/tc_option_data.c, we have:

    {   "PMAG-BA ",     "fb",     0,      0,    'D',    0},     /* CFB */
    {   "PMAG-AA ",     "fb",     0,      0,    'D',    0},     /* MFB */
    {   "PMAG-CA ",     "px",     0,      1,    'D',    0},     /* 2DA */
    {   "PMAG-DA ",     "px",     0,      1,    'D',    0},     /* LM-3DA */
    {   "PMAG-FA ",     "px",     0,      1,    'D',    0},     /* HE-3DA */
    {   "PMAG-FB ",     "px",     0,      1,    'D',    0},     /* HE+3DA */
    {   "PMAGB-FA",     "px",     0,      1,    'D',    0},     /* HE+3DA */
    {   "PMAGB-FB",     "px",     0,      1,    'D',    0},     /* HE+3DA */
    {   "PMAGB-BA",     "fb",     0,      1,    'D',    0},     /* SFB */
    {   "PMAG-RO ",     "fb",     0,      0,    'D',    0},  /* Raster Ops */
    {   "PMAG-JA ",     "fb",     0,      0,    'D',    0},  /* Raster Ops */
    {   "PMAGB-JA",     "fb",     0,      0,    'D',    0},  /* Raster Ops */

which I would say is "authoritive" PROM id strings.  Other files
(fb_data.c and px_data.c) contain more info on each model.
