Released ~1995: This Pentium 100 PC is one of the many typical “gray boxes” of the 90’s. I don’t know the company behind the box as it looks anonymous with no logo, it got a model number though and made in Scotland on a sticker at the rear.

The first Pentium microprocessor was introduced by Intel in 1993 and was dubbed P5. The P5 was designed by the same Santa Clara team which designed the 386 and 486.  The P5 was followed by the P54C in 1994, also known as Pentium-S.

My PC: Pentium 100
I’ve found this computer in the electrical waste disposal at my work place together with a matching PS keyboard without the “Windows” keys. It looked clean and in good shape, except it had the hard disk removed. I also had to replace the coin cell CMOS battery, and I used an IDE-CF card adapter for hard disk. I had an 8 GB CF card, and had to set sector, headers, and cylinders manually in BIOS settings to recognize it as an 504 MB hard disk, as this is the limit for PC’s of this area. Once this was in place, I could boot up an MS-DOS floppy disk and run FDISK program to make an 504 MB partition on it, and use the SYS command to make it bootable.

I'm collecting classic computers and video games, stretching from the 70's into the 90's. Restoration, history, usage ...
