VCF SW was this past weekend near Dallas, Texas.
Here are some highlights from my perspective.

I may be talking nonsense, but you describe the Tektronix 4054 as a
6800-based system. I thought the 4051 used that processor, but the
4052 and 4054 used a board of AM2900-series bitslice chips that
implement a processor with an instruction set similar to the 6800 but
with no BCD operations and some 16 bit extensions.
