Texas Instruments TI-99/4A

The TI-99/4 is a home computer released in 1979. It retailed for $525 USD, which is equivalent to $1,490 after adjusting for inflation (in 2020)! Partially due to its exuberant price and lack of software support, it only sold around twenty-thousand units.

The TI-99/4A is an incremental upgrade to the original TI-99/4, at half the price of the original unit. Needless to say it was much more successful, it sold around three million units.

Does Batocera support emulating both models? Good question!
