Going against that famous not-actually-a-Bill-Gates quote, 640K isn't enough for me, so today I'm building a modern reproduction of the Compaq Portable III's memory expansion board and maxing it out.

Disclaimer!
I am NOT an expert, I have genuinely NO idea what I'm doing, and mostly just glue things together and use a lot of Google-fu until stuff works. I've been tinkering with electronics since I was a kid but have no formal training and will probably do things incorrectly. If you learn something from this, that's awesome, but trust me - I'm learning too!
