Any TMS34010 experts out there? I'm trying to sort out the ROM mapping for this one ISA video card. As best I can tell, the boot vector is the last word in the memory space, but in this case it's just FFFF, so, err, it points to itself?

Vectrix EX1280. The ROMs are on Bitsavers.
The end of the ROM looks like this, but up towards the top it looks like perfectly legitimate TMS code.pic.twitter.com/cgKntGkeuo

Give this a try: https://pastebin.com/Qnrjr4Gv Note that the address granularity of the 340x0 is 1 bit.pic.twitter.com/9gtl5JMMDh

Interesting! Seems like the bottom half is code and the top half is font data. Makes me wonder where the top half maps, in that case.
