I wish I owned an Amiga or Atari computer. In the 90's everyone was so obsessed with getting better faster computers I likely could have gotten one for pretty cheap. We forget the capabilities of those systems because they can't do some things that we think are important. But then we also forget all they can do. I wouldn't be a programmer today were it not for those early systems that had BASIC built in. I got fascinated and obsessed with programming on a computer from the 80's. How different of a world would we be in if people weren't so obsessed with buying faster computers and instead kept buying systems that were more open and worked on upgrades and modifications more. I wish I had. Now I can only wish and realize my time is limited.
I had a Commodore 64 as my only computer from 1987 until 1993. Then I upgraded to a 486 based PC and the race was on. It was sometime later before I had an Amiga.
I had a TI 99/4a until sometime in the 90's when we got a Macintosh Performa 550, which was 68030 based with a floating point co-processor. It was quite capable for the day and was very helpful in my education...but now looking back on it, I wish I had something in between, possibly with access to BBS services. I didn't even know that BBSes existed until their time was over.
I started calling BBSes around the time I got my PC in 1993. For the next few years they were still very popular. However, that popularity declined quickly with the rise of the internet. By 1997 or so they were getting hard to find. There are a bunch around these days, accessible via telnet or ssh but what was nice about BBSes back in the day was that they were local with local callers.
