Motherboard Versions

2014-01-12T07:22:31Z

Ian: /* Version 2 */

There are at least three different versions of the UK101 motherboard.
==Version 1==
[[File:motherboard_version_1.jpg|thumb|150px]]
The first version of the motherboard that was available for sale is distinguished by the lack of the green solder mask.
==Version 2==
[[File:motherboard_version_2.jpg|thumb|150px]][[File:motherboard_version_2_bottom.jpg|thumb|150px]]
The second, and most popular, version of the motherboard has a green solder mask on both sides of the board. It is different from the third version by not having the word "EPROM" on the lower left of the board.
Thanks to the hard work of jimmydeath on the [http://stardot.org.uk/forums/viewtopic.php?f=11&t=6108 Stairway to Hell forums], we have very high resolution scans of both sides of the version 2 motherboard. These files are ZIP archives of TIFF files, and are *very large*.

*[http://www.compukit.org/pcb_images/uk101_version2_bottom.zip uk101_version2_bottom.zip] (669 Mb)

==Version 3==
[[File:motherboard_version_3.jpg|thumb|150px]]
The third version of the motherboard is distinguished by the word "EPROM" appearing in the top copper layer in the lower left corner. It is assumed that this board has the correct chip select lines for EPROM versions of all of the ROM chips.

[[File:PE197908-cover.jpg|left|300px|Practical Electronics - August 1979]]A series of articles describing how to construct the Compukit UK-101 computer appeared in Practical Electronics - a UK electronics magazine founded in 1964.

The [[Construction_Article|articles]] ran from August through November 1979, with followup articles appearing over the next several years. The articles were written by Dr. A. A. Berk, B.Sc. Ph.D. - an individual that appears not to have left much of an Internet footprint.

Ah, I remember vividly that August 1979 edition of Practical Electronics. I was 11 years old, and from the moment I laid eyes on that cover, I just knew that I was going to build one.

Several months and much pocket money later, I had my Compukit. What an amazing machine - 4k of memory was more than enough for my first simple BASIC programs. I soon learnt 6502 machine code.

Years passed, and I moved on to other machines (most of the Atari 8-bit and 16-bit line, followed by IBM clones and Macintoshes). Somewhere along the line, my Compukit and I parted company. Without a Compukit, I decided to do the next best thing - I built an emulator in software!

I hope you enjoy the various Compukit information that I've gathered here. If you have anything to contribute please [mailto:ian@compukit.org email me].
