Texas Instruments TI 99/4A 32K Sidecar Memory Expansion Card What is it? Functionally equivalent to TI 99/4a Sidecar or PEB 32k expansion. It plugs into the sideport of the TI with an edge card connector.  It runs off of +5v, using about 5-10mah. There is one configuration jumper to either take power from an external 5.5/2.1mm tip-positive 5.0 VDC power supply, or the TI-99/4A sideport. It will work with your Speech Syntehsizer installed IF you use an external power supply (available separately) OR modify your speech synthesizer to supply power at pin #1. Many of the newer home-brew cartridge titles also require a 32k expansion and will work with this board.  In conjunction with a FlashROM99 or FinalGROM99 cartridge (available separately), you can play 32K games without the need for a Peripheral Expansion Box (PEB) or even a nanoPEB!  This includes an assembled and tested 32K board AND A CASE.  This is in a 3D printed case.  It is fully functional AND it is easily opened to add a TIPI
