JB's GitHub page for the RC2014 board refers to an original article on the RetroBrew Computers site about a TMS9918 circuit, but that's been returning a 500 error for a while. 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

I suppose I'd better point out for postage etc. reasons, I'm in the UK.

@chris Hi Chris, I'm waiting for the PCBs to arrive. Happy to do a kit or make up the board. Drop me a line at nigel@linker3000.com

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.

Reminds me to try to fix my ThinkPad T420. It was running fine until something shorted in the power circuit and any PSU I connect goes in to shutdown mode. Hopefully just a power FET. The little buddy (i5/8GB) was doing fine on MX Linux.

How odd.

I've called HMRC a few times from my mobile phone and have posted here about it and nowhere else, and now the Reddit phone app's list of other subreddits in which I might be interested includes posts from r/HMRC.

I checked and the app didn't have permission to read my contacts.

Uncanny?!

Ours was the front end for an engineering team developing algorithms for flight simulator visual systems. The grunt work was done by a bank of connected Transputers. Once the code was validated it went into custom silicon.

If course, you could later do the same level of graphics with a Playstation 2

The VAX 11/750 sysop in me groaned.
