TMS99105 Super Ti-99/4A
**
For anyone designing or thinking of designing their own ‘Super’ Ti-99/4A microcomputer, I’ve asked a Chinese supplier to list a compilation of ICs which may help get you started. The Heart or Key to the list of ICs is the TMS99105, which is considerably faster than the original TMS9900 CPU.
As these Chips are NOS (New Old Stock) or working Pulls, they should be tested as these Integrated Circuits (ICs) are 35+ years old !
You'll find them here: https://www.ebay.com/itm/Homebrew-DIY-T ... SwsKddJfGv
Take a look at ;
For those not familiar with the CPU in the Ti-99/4A then take a look at : Wiki TMS9900 https://en.wikipedia.org/wiki/Texas_Instruments_TMS9900
There’s also a most interesting project on YouTube :
