I also got an unbranded XT-clone at the same time. My own first PC experience was on a couple of different Olivetti PCs - the M24 and M240. I was about to say it's not so old, but it's actually 10 years old this year. Converter sorted out so I can use it in hi-res mode. Unfortunately I have no disk drive cable currently, so all I've really done with it is play Ballblazer as it was intended.
Pong still plays well.
Indy One of the slower ones, unfortunately. Pretty case too. Thanks to a donor IPC, it's got a bwtwo framebuffer now, and an original Sun harddisk. I'm working on blagging a mousemat. I'd like one of those back too.
