> Take your time to solder all the components on the board. There are a lot of solder points and if you don't have patience in general, then this project might not be for you.
This was painful to read. 14 year old me finally managed to get the NASCOM 2, my first ever computer. It came as a kit with 2,000+ solder points, but patience was never my virtual and certainly not at 14 year old so my work wasn't perfect and worse, wasn't properly checked. The original Z-80 died and I had to get professional help to get it working. (And learn to program: Z-80 in binary hex codes -- didn't get the memory necessary for the Microsoft BASIC until later). Still have this computer.
Understatement.
