  I have the TMS34010 data sheet here, but what we
really need is the user 
 manual. The data sheet has the pinouts, timing diagrams, etc in it - 
 hardware info. It appears that programming info was mostly in the user 
 manual, though. 
The tms34020 was faster, new instructions, bigger address & data. You could
even attach a FP unit to it.

  Are you sure about that? Most VRAMs (certainly the
ones in use when the 
 34010 came out) seem to be nothing more than DRAMs with a second address 
 port that transfers one row of data into a shift register. The bitstream 
 from the S/R is fed to the video circuitry. No bit-blit operations. 
The second generation had something like mask/logical operations. Comes out
with the tms34010. I should have the application notes somewhere :-((
