TMS9118-9128
About the TMS9118-9128 PCB
TMS9118-9128 is an open source PCB design by polpo, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 20.3 × 50.8 mm, with 4 components from 2 distinct parts.
From the project
Adapter that allows computers that use the TMS9118 or TMS9918 VDP to use a TMS9128 or TMS9928 and TMS-RGB for RGB output.
This is a PCB that will let you plug a TMS9128 or TMS9928 VDP, along with a TMS-RGB, into a system that uses a TMS9118 or TMS9918 VDP. Such systems include numerous MSX computers, the NABU, and the TI 99/4A.
The adapter is intended to go in the sandwich of: TMS9x28 - socket - TMS-RGB - adapter - pin headers - socket - system motherboard.
There are two versions of the adapter, one for the TMS9128 and one for the TMS9928:
