I bought this strange 386 processor today.
It has more pin than normal 386 processor.

Hmm...looks more like a 486 in terms of size. The Chips 386 is rare, I wonder if this might be a fake?

I sent you PM about the boards few weeks ago;)
I wrote 144pin sockets, but in reality these have 175pin ones.
Please PM me! |

| Just check one of the board. There is "386 BIOS PLUS" marking on the BIOS EPROM chip. |

| Still checking the boards. "PEAK DI" BIOS mark instead of "PEAK DM". Also, there is a weird Landmak 2.00 results.... |
