See pics and ROM images at http://everist.org/pics/televideo_924/
I haven't dumped the chargen chip yet, because I don't know what it is, and suspect it's more complex than just a ROM.
24 pin character gen ROM/? at U10 is marked:

VTi (logo)
  350 RN 118
  2333-5006
  8000142
  (c)TELEVIDEO 1983
  KOREA-AE

See http://everist.org/pics/televideo_924/20190424_3338_chargen.jpg

The keyboard controller is an 8049. Firmware not readable.
