Typical - less common old parts are like buses: you wait for ever for one to come along, then two arrive at once 😜
I've been messing around with an incredibly tempramental ECS VL486E for over a year and a half, but after getting it working 6 months ago it died on me again. I'd pretty much given up on it and had been looking for any remotely affordable EISA system since then. On a whim I gave it one last bash this weekend and actually got it fully working at last yesterday. Today, what turns up locally but a huge full-AT Micronics 80486 ASIC EISA 50MHz. Untested but NIB apparently. I definitely don't need two 486 EISA systems, but given how much 'fun' I'm having with the ECS board I wouldn't mind a plan B, so did a lowball offer on the off chance. It got accepted, so in a few days I should have an impressive pic to share. Worst-case it's dead, but there's no battery installed on the board, so the biggest concern isn't there, just a few tantalum caps that might prove explosive in their old age...
