I got some shots of my system. :) Will make them available later.

The interesting thing about these two similar computers is that the board
layout is distinctly different WRT the SS-50 vs. the SS-30 busses. In mine
they are perpendicular, and in Jeff's they are parallel. Quite fascianting
when you think that a decision by SWTPC was made to make the change.
(Mine is no doubt the earlier -traditional layout from the 6800 days.)

Jeff's is no doubt SWTPC's reaction to the Gimix and Helix boxes of the day.

Interesting to find out what manufacture numbers (quantity) exist for both
All would die with the advent of the PC, but the historical aspects of the
bus became more fascianting today once I realized that major switch.
