Fascinating. The datasheet of that MCU does not have a date on it - pity. It has 48-v capable IO lines, and they do say it is suitable for driving VFDs directly. 1K of ROM and 80 bytes of 4-bit RAM, and it does BCD arithmetic, suggesting it may have been aimed at the pocket calculator market. It has some surprising features for an old chip - configurable pullups on the I/O, bit manipulation instructions, built-in clock generator. If it wasn't an OTP (One-time-programmable) chip it would be fun to have a play with.
I remember using OTP MCU even 13 years backs, just because of huge difference in price of the OTP MCUs compared to the ROM based (programmable) MCUs. For mass scale production OTP MCUs was the choice. But no feature enhancement, no upgradability!! Things are much easier now a days!! Amazingly things have changed so much in electronics!! Contemporary video gaming has evolved to be so different and in future that too might converge towards a common gadget for everything. :)
