486 based self-assembled computer

Greetings, in a previous post I wrote that I was looking for a 486 processor for future projects. Almost the next day, Alexander contacted me with the nickname "alexzar76". Absolutely free of charge, he offered me a motherboard on 3 sockets and two different processors for it. After a while I received them. Thank you, Alexander! This post was made possible thanks to him.

After receiving my collection of processors began to look like this:



Of them, the two upper left ones were received from Alexander (these are Cyrix Cx486 / 66 and Intel i486DX4-100).

It is worth noting that on the iCOMP index , my four is the best in the line from Inlel.

Motherboard

This is the same board that they gave me along with the CPU. It has 4 ISA and 3 VESA Local Bus (VLB) slots, which use some features of the 486th architecture.
Also on it are 4 connectors for SIMM-30 pin and 2 for SIMM 72 pin. Most likely, it holds a maximum of 64 MB, 32 in each of the 72 pin connectors. (Of course, only 1 of the memory types can be used at a time) The

BIOS of this machine has a graphical interface and uses a COM mouse! It looks like a crooked zakos under early Windows, however, there is a moment with the entrance to the BIOS in the video.

GPU

It was planned to use a video card on a Cirrus logic chip under the VLB bus, but it was not possible to get it. In appearance, there are no complaints against it, the bus speed was set to 33, and the video card was inserted in the slot closest to the CPU. It is possible that I could not properly configure it.

Be that as it may, I had to take out the 286th REALTEK RTVGA V21 004, which we already knew, and continue the experiments, although with 256kb of video memory everything was very dull.

RAM

Two SIMM 72 PINs of 16 MB each

IDE / COM / LPT Controller

I used this card, as they say "Noname" (or I did not find the name).

HDD

I pulled the disk out of my bins, it was originally in the assembly with the second pentium.
This is a Quantum EX3.2A at 3.2 GB. The condition is close to perfect.

Audio

As the sound, I used the trivial Sound Blaster CT4170 on a Vibra 16XV chip

Network

A 3C509B-TPO network card from 3COM was used.

OS

The operating system for my build was the Windows-95 distribution and the corresponding Plus! Package.

Unfortunately, I could not find working drivers on my graphics card. Therefore, everything works in 16 colors and without acceleration (if at all possible on such a weak card).

The rest was installed independently. After adding the desired protocol, the network rises and works normally.

Practice

And of course I recorded a video! The quality is lame due to my experiments with a fixed focus, but everything is readable.

PS

Thank you for helping the irc channel # 16bit and bocha personally. If you are interested in something or have something to say, welcome to the comments.
