Here you will find +3 hardware related material, mostly suitable for all +3 versions.
The subjects covered are:
- The (128K) sound issue
- The IN #FF port issue
- Adding composite video output
- Replacing the original 3” drive with a 3.5” 720K DS DD drive
Although I am referring to the +3, the first three items may apply to the +2A as well.
Note: if you have (deep) knowledge in electronics, feel free to apply – or even improve – the solutions I’m offering here. If not, you may read it just for curiosity :)
There is also a hardware section describing my self-build +3. That is a project under construction and/or in a continuous process of modifying and improving some parts, like the CPU access timing, memory type, video board, PSU, etc. Probably For sure, that’s a never ending project.
