Mine’s also an issue 6 with the soldered epoxy blob style ULA. The ULA was actually my main worry waiting for it to arrive, since I’d seen some stories before of that being a source of problems. Fortunately, mine seems to work fine as-is.Ronin47 wrote: ↑Thu Jun 10, 2021 11:43 pmMine is an issue 6, the ULA is soldered in, I can't help but think that's better than the socket. Might be worth looking at the CPU, I had a dead one in a BBC B recently, they are pretty cheap.baz4096 wrote: ↑Thu Jun 10, 2021 8:56 pmI was thinking perhaps I got the "better" machine here, given the switch problems and general clean up you guys had; mine was super clean, all things considered.
However, after my PSU order arrived, it looks like I might have a dead ULA. It's a socketed Issue 4 one, with the little metal plate. There was some residue between the contacts on the chip, and the socket wasn't spotless, but even after a gentle application of IPA, I'm still getting a solid grey rectangle on screen. I'm not giving up though! Any suggestions where to start? I should probably open a new thread over in 8-bit Hardware...
I ordered a handful of key switches from Mr. RetroClinic this morning along with the keyboard ribbon, so once those arrive I should have a fully working Electron (minus the RF modulator that I’m not replacing for now).
