We're just about settled on the format for the
QSIC RKV11-F/RPV11-D
panels.
PS: Here's the latest rev of our thinking:

if anyone has any comments. (Since the format is entirely set by the FPGA,
it's 'easy' to tweak it, if there's a desirable improvement.)
It's not the same as the old DEC RK11-B/RK11-C or RP11-C inlays, in part
because we want to be able to show the address, and on a QBUS machine, that's
22 bits. Also, many of the fields don't apply to the QSIC (e.g. internal drive
signals, 36-bit data buffer on the RP11, etc); we figured it would be better
to recycle those lights for something useful (e.g. the address and word
count).
