CIRCLE WITH A DOT

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

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?!
