Am386DX Tower

This is a modest 386 of ca. 1994. It contains quite modern Baby-AT mainboard, 8MB of RAM and Trident ISA video board in 16-bit ISA slot. Hard disk is Samsung 250MB. It has also a Creative SoundBlaster board and some network adapter.
The mainboard has been made probably by STM (whatever it is, probably not ST Microelectronics) and it has interesting CPU - it's AMD's 386DX running at 40MHz but unlikely most of them, this one has "Microsoft Windows Compatible" printed on its package.
Graphics adapter is a typical 512kB Trident TVGA9000 which allows to get 800x600 at 256 colors - totally sufficient for effective work in Microsoft Windows 3.11 environment and its productivity applications.

Starting

The mainboard has quite modern BIOS, typical rather for 486. It allows to configure memory timings or I/O areas. Generally it starts as all PCs and can boot from floppy or hard disk drive.
