Sorry about the uNOTE confusion... I was focused and just used the
reference from the OEM version. I was aware but had mentally excluded
the older Microcomputer Products Group/Components Group version.
If you look at the Memory Comparison table in this OEM uNOTE, it only
lists Block Mode for "JD/JE ONLY". Hence my comment about it not being
on the JB/JC.

I went and looked at uNOTE #28, after I found it (it's not in the initial set
of uNOTEs, but in the second set - the so-called 'OEM uNOTEs"; note that the
numbers were re-used between the two sets, so there are _two different_ uNOTE
#28's).
I couldn't find anything there about the JB/JC not doing block mode? All it
says is they "can not be used in a Q-BUS system due to gate array
incompatibilities".
