Notes

PCB is marked: "UNIVERSAL 8339A" on component side

No proof at all that custom CF37201N is really a TMS 1000 family chip, even if there are some suspect that it is; mainly due to being manufactured by TI and having 2 support chips (TMS1025N2L) which are spedifically ment for TMS 1000 family.
