Treasure hunt victory. Just found a DEC F-11 CPU from Shenzhen. The second-generation of LSI-11, PDP-11 on a chip.

Just received the DEC F-11 CPU from my previous treasure hunt. This is the chip that powered the second generation of LSI-11 machines, including PDP-11/23 and PDP-11/24. Now I'm a proud owner of a PDP-11 on a chip.

You can still find some in the USA, but I never expected to find one in China. But not surprising, I can imagine that someday, somewhere in Guiyu, a container full of scrapped industrial equipment arrived, one of them was a PDP-11 (or perhaps only a KDF11 CPU board), it was sold as scrap metal and got scavenged here.

@niconiconi at various points I've been very tempted to buy one of the soviet PDP-11-on-a-chip designs on ebay

@izaya I'd love to buy them but I can't read Russian datasheets...

@niconiconi @izaya I wonder if @rin might know someone who knows russian, is into retrocomputing, and could help

@kumicota @wolf480pl @niconiconi @rin there's the bonus hurdle of the fact that most of them I've seen are in cursed packages like QIP28, with two rows of 14 pins on either side.
