Sounds like a jolly good idea. I'd almost bet that one of the read only
registers was used as a write latch, whose decoded output then determined
which register the next read or write went to? Similar to how the WP-RS &
WP-II worked to address the 32 registers in that chip? But I have no clue
which of the rick Uland's that google would disgorge is our Rick Uland.
