<![CDATA[My next RC2014 compatible board build will be the TMS9918A video card by J B Langston.]]>My next RC2014 compatible board build will be the TMS9918A video card by J B Langston. I've ordered 5 PCBs and have enough parts to make up all 5, although I only have 2 x TMS9918As.

I'm thinking of making up all 5 boards and selling off 3 - WITHOUT the TMS chip* - for pretty much parts cost + a small amount for my time and solder + postage. Would anyone be interested?

*You can get them from various places as pulls or NOS. I suppose I could source and test them too.

The Internet Archive to the rescue: https://web.archive.org/web/20240117013003/https://retrobrewcomputers.org/n8vem-pbwiki-archive/0/35845334/48860720/33053543/SRAM%20Replacement%20for%20TMS99x8%20VRAM.pdf

Hadn’t been used in decades so might as well give it a new life!
