Ian, the modules (rack) I used were also Yamaha..
I used the 81z as you did, and the 8 in 1 TX rack..I can't remember the model..I think it was a TX 802..
And not to forget the Yamaha RX120 drum machine and Roland TR707 unit too..
SH101 was my bass ...JX10 controlled the Yamaha's..and a pair of Alpha Juno 2's for color sounds..replaced the JX8p's (lighter)..
The JX 10 remained my favorite board for many years..
I tried the Rhodes and Hammond set ups....but after selling Hammond in the 60's..I didn't want to haul them anymore..
The multi keyboard era was great..I enjoyed the combinations..and was never totally brand oriented...I mixed them all..
I always thought it would be fun..to set up big set ups again...sure is far from necessary..but would look neat...
Imagine the rocket ship look of the MediaStation ..flanked by the G70, and a A-33 controller...and of course an accordion strapped on...
