Ok, gang ... here's some info and pic's from my latest 486 rig build.
Some background first, I oiginally got this Commodore 486 pc around 20 years ago but never got around really using it much or equipping it to the teeth.
I put it on storage in 2010/2011 and it has been sitting there since I resurrected it a couple of week ago. I did that because I currently don't have any DOS machine to play games on and I have a crush for Amiga looking Commodore PC's
The case has some similarities with the Commodore Amiga 4000 computers. It has the factory motherboard made by Abit, the model "AT4".
It originally vame with an Intel 486DX 33Mhz which I have upgraded with an Intel Overdrive 486DX4 100Mhz.
The spec's:
- Motherboard: Abit AT4
- CPU: Intel Overdrive 486DX4 100Mhz
- RAM: 8MB, 8x1MB 30pin simm's
- Graphics card: Diamond Speedstar 24 ISA
- Sound card(s):
Sound blaster Pro CT1330A rev 6
Gravis Ultrasound Classic Rev 3.7
- Midi: Midia Midi Card Plus, MPU401 midi controller
- Storage controller: Adaptec 1542CF
- Storage: Zuluscsi RP2040 compact scsi to sd adapter
- I/O controller - some no-name 8-bit ISA card
- Floppy drives: 1.44MB 3.5 inch drive & 1.2MB 5 1/4 inch drive
- OS: MS-DOS 6.22 & Windows 3.11
The Zuluscsi adapter makes is very easy to add files/folders to the harddrive by mountning the image on the sd card in Winimage for example and injecting what you want.
