Another Siemens PCD-2 - but surprisingly with a Intel 386SX CPU ?!

Recently I found another Siemens PCD-2, but this one was totally different from the other.
The main difference - instead of a Intel 286 CPU, I found a 386SX CPU (20 MHz), but still inserted on a CPU card (no "classic" mainboard inside).


There was also no proprietary Siemens BIOS used, instead, I found an AMI BIOS:

Chipset was still from OPTI, a lot of SIMMs can be also found on the CPU card.

I had to replace the 3.5" floppy drive (this happens not often), a Seagate 3144AT (IDE) runs fine (almost fine, the drive already makes some noise, but at the moment not too loud).

But Arkanoid II is running well, so I guess I am satisfied also with a 386SX PCD2 :-)


Somebody else already replaced the 286 CPU card with a better CPU, too.
See "related Link", may be this PCD-2 here was also already modified in a similar manner.

If you're curious about the original PCD-2, look at my page >here<.
