Computers
My very first one was Amiga500 in the late 80's with added memory to total 1MB. Mainly used it for gaming. The funny part is, I still have it on the storage. Although I haven't try it for over a decade.
I kinda jumped over the early days of home PCs straight to pentium era. After the first one, I think it was Hewlett-Packard P120, I've always build my custom setups including watercoolings from early 2000's till today. I've also done my share of overclocking etc.
On the software side I've obviously done some websites including some bulletin boards back in the days. None of these are up and running anymore. This site is just one example of my web skills.
