Questers 386sx desktop

A cheapest way to get 386 in early 1990s was to get a 386sx. These processors were crippled-down, a bit slower and many times with none or almost no cache possibility. 2MB RAM was usually enough for operation faster than 286, but most of times no extended features wear used - these computers were still used as DOS machines.
This particular machine has been re-built with specification, as original boards were ruined (yes, battery leak). It is still a 25MHz 386sx, with 2MB of RAM and a simple 8-bit ISA VGA, which was a typical solution for having better VGA instead of Hercules. Serial and parallel ports are supplied with Goldstar GW451C controller and floppy/IDE controller is a Longshine LCS. The hard disk is a WD L42S, a typical thing to go these times if someone wanted IDE but not wanted a "full height" form factor.
Summing up, a nice DOS machine, but much slower in Windows 3.x operation than 386DX with 4MB of RAM.

Very typical mainboard with extended configuration options related to cache and memory. It is possible to configure it for faster and slower RAM (BIOS for analysis).
