What is TPA?
Ok, this is the list of features/changes,
-full 64K, a single 32pin 128Kx8 will save a lot of board real estate.
-Phantom line to "create holes" by external cards
-Jumper blocks of memory for external S-100 bus mapping.
-An extra UART for a 2nd serial port.
-Sockets for both the IMSAI and ALTAIR front panels

With the board the way it is. You can run CPM with just one card with full TPA. This is good.!!!! N
