While waiting for power and network to be restored, I had looked through
some refdisks.

7080a - DEV129.DGS 31,608, 1990-06-29
70486 - DEV129.DGS 37,417, 1990-06-27
RFP75 - DEV129.DGS 37,527, 1990-09-18

Applying my MENSA-class intellect... I see a pattern. The 7080 lacks an
actual processor board and is @ 6KB smaller.

The 70486 and P75 BOTH have an actual processor board, and BOTH
DEV129.DGS are within @ 100 Bytes of each other. Part of the difference
should be due to different POS values. My SWAG is that they are closest, byte-wise.
