TBA's TI 99/4A 32K Sidecar Memory Expansion Card with case
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 has an opening for TIPI, but since I do not have a TIPI, I cannot verify that there is enough clearance. There should be, but let me know if the case needs to be changed. Case is sealed. If you, for some reason, want to be able to open it, I can fit it with screws for an additional $10 (it is a rather involved process to get it sealed with the screw holes on the board. In the next run, I will enlarge the holes).
Other shell colors are available at additional expense.
