WHEN THE EYES FLASH ON THE SCREEN...SHOOT! Thanks for visiting. This is my journey to play Wild Gunman (1974) from Nintendo after getting my hands on some of the 16mm films used in the original machine. This video released in 2026 is 50 years after its North American release in 1976.

TMS5110A Voice Chips

Details
Created: 08 January 2019

While repairing some Bagman boards I found that the TMS5110A was getting hard to find in a standard DIP package. Even those being sold as compatible showed up in this shrink-DIP format. So I had some adapters made!

These are old stock TMS5110ANL chips in an SDIP package with a custom made SDIP-DIP adapter. This will fit into a standard sized 28-pin DIP socket like the original used on Bagman.
 
These come preassembled (hand-soldered) with machined pin headers, which fit into the original socket (with a bit of force!). Each one will be tested in a Bagman before shipping.

Please contact me at This email address is being protected from spambots. You need JavaScript enabled to view it. if you wish to order. Standard price is $20 USD plus shipping.
