Sometimes it takes a little creativity to even call these "games", haha.

Yeah, I found a few patents for electronic organs as well. Interesting that there were none for electronic video games.

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. :)

definitely a great creativity used to build games with the early technology chips.

OLD MCU...

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.

Thanks for the heads up! Here's the datasheet for that chip, in case you want more information.

HAHA, it isn't! I bet that is one reason Bambino games aren't around much anymore.

The chip is the Hitachi HD38750 4-bit PMOS ROM-based MCU.

lack of wear

You mention the lack of wear - even the label on bottom looks 'good'.

I think this tells why you don't find more info.

Must not have been much fun to play !

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
