Update on known tsp50cxx chips: 1. Keynote speech synthesizer module that Kevtris has ("2472JXT // CSM10075AN") 2. MB Electronic Talking Battleship(1989)[Oct 92] ("2234673 // BATTLESHIP // CSM10017AN") 3. MB Electronic Talking Battleship(1989)[Apr 96] ("5BATX6T // BATTLESHIP-2 // CSM10259AN") 4. MB Electronic Talking Battleship(1989)[? 98 or 99] ("85AX02T // B-SHIP 1998 // CSM10287AN") 5. MB Dream Phone(1991) ("5507 JKT // DREAM PHONE2 // CSM11120AN") 6. Echo II Speech Synthesizer Card for Apple2 (1989) ("ECHO-2 SEC // LU 9020 // 25954 PHILIPPINES") [note this uses a different, earlier tsp50c01 or 02 or other part(probably 02 given the '25954' number starts with 2) with a slightly different pinout to tsp50c10] 7. MB Omega Virus(1992) ("3253ACT // OMEGA VIRUS // CSM11161AN") 8. Mystery Vtech unit from Dumping Union ("84C91HT // VIDEO TECH // CSM10150AN") we suspect that MB Mall Madness also uses a tsp50cxx but don't have the chip label yet. Also from Boardgamegeek forums we know a German voice version of Omega Virus exists as well.
What we know about the tsp50cxx marking numbers: First line: First digit is almost certainly the last digit of the manufacturing year. Unclear what the rest is. Second line: Product name, if present. Third Line: "CSM", then "10" for tsp50c10 or "11" for tsp50c11, then 3-digit mask code, then 'as a whole series' silicon stepping revision (usually "A") and "N" for plastic package.
Unclear what changed between the 3 revisions of Talking battleship. LN owns one of the '10 92' made boards, Zorix owns a '4 96' made one. Sean owns a 1998 one but the MCU has been decapped already and didn't seem readable optically, so we could use another 1998 one if possible.
