Soldering 8 bit ISA bus slots on IBM 5150 Motherboard

In this short video I am soldering the 8-bit ISA bus slots onto the motherboard of the IBM 5150 PC.

I absolutely love DIY and RETRO electronics, I love building devices with my own hands and basic tools.

Technical Spec Of This Project:
This kit is a faithful reproduction of the classic IBM PC 5150 motherboard from 1982. PC-Retro have been in development of this product for over 1 year. They started with the original circuit diagrams, as published by IBM on their Technical Reference Manual. These open source circuit diagrams launched an explosion in PC clone products. Reverse engineering the original IBM board was a substantial undertaking, as the creators found many differences between the 'official' circuit diagrams and actual board construction. Additionally, one can imagine the complexity of trouble-shooting this board and verifying the correct operation! Not to mention the logistical challenge of sourcing the original vintage electronic parts.

IBM PC advertisement, 1982:

IBM is proud to announce a product you may have a personal interest in. It's a tool that could soon be on your desk, in your home or in your child's schoolroom. It can make a surprising difference in the way you work, learn or otherwise approach the complexities (and some of the simple pleasures) of living.

It's the computer we're making for you.

The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It is IBM model number 5150, and was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida.

The generic term "personal computer" was in use before 1981, applied as early as 1972 to the Xerox PARC's Alto, but because of the success of the IBM Personal Computer, the term "PC" came to mean more specifically a desktop microcomputer compatible with IBM's PC products. Within a short time of the introduction, third-party suppliers of peripheral devices, expansion cards, and software proliferated; the influence of the IBM PC on the personal computer market was substantial in standardizing a platform for personal computers. "IBM compatible" became an important criterion for sales growth; only the Apple Macintosh family kept significant market share without compatibility with the IBM personal computer.
