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.

More treasure hunt victory from Shenzhen: Intersil IM-6100, IM-6100A and Harris HD-6120 CPUs - PDP-8-on-a-chip! Also known as "CMOS-8s".

@phooky I guess the selling point here was 12-bit ADC interfacing.
