This TMS9918 display card is based on a popular circuit to use SRAM with the TMS9918.
There are a couple of changes however:
- The 74LS574 (U5) I have replaced with a 74245 bus tranceiver.
- I'm not using the delay circuit. I do have it as an option, however haven't needed it.
The emulator includes full support for this TMS9918 card using my vrEmuTms9918 emulator library.
- First custom PCB
- Initial hand-wired version

Thanks to PCBWay for supporting this build.
