About the TMSAdapterTC01 PCB
TMSAdapterTC01 is an open source PCB design by Board-Folk, published on GitHub. It is a 2-layer board measuring 55.9 × 88.9 mm, with 22 components from 8 distinct parts.
Other key parts include the TMS9929A and MB8118. By type, the board carries 9 ICs, 7 capacitors, 4 resistors, 1 connector and 1 diode.
From the project
Tatung Einstein TC-01
Adapter board to allow the use of a TMS9929 chip on the Tatung Einstein TC-01. The TMS9929 is easier to find than the original VDP, but requires a different type of RAM which needs fitting to the adapter.
Intended to work with 5V 1x16K DRAM chips, e.g. MB8118 or compatible, but can accept 4164 and 41256 RAM, which although is a waste as the majority of the RAM isn't used are more easily and cheaply obtained. This will not work with 4116 RAM as the board doesn't provide the correct voltages.
