TMS1100NLL MP3403 DBS 7836 SINGAPORE some game board with 7-segs.
|
||||
|
||||
What old electronic game is this?
|
||||
|
||||
some clues:
|
||||
- it's from 1978
|
||||
- Merlin is MP3404, Amaze-A-Tron is MP3405, this one is MP3403
|
||||
- it plays some short jingles (you need to be lucky with button mashing),
|
||||
jingles feel like maybe a horse racing game
