In 1992 I'd just left school and had started attending college and working part-time. Almost every cent of that income went into PC hardware - the benefit for me being that I could buy 1 PC component every month with my paycheck and slowly build up a machine of my own. My family had an XT clone with mono herc/CGA graphics at the time, which was rapidly becoming useless and at first I would "borrow" components from that PC to complete my own machine - often reassembling that XT whenever the family needed to use it.
My first piece was an old 80286 motherboard that my father got from a PC store that was trying to get rid of it in an old desktop-style AT case. To add to that I got a Trident 8900 ISA VGA card - borrowing the multi IO card and HD controller from the XT at first. Later I upgraded that with a 1.4MB floppy disk drive, a 16-bit IDE/Multi IO card to replace the one from the XT and then eventually a Connor 80MB IDE hard drive.
I remember the VGA monitor was a massive outlay for me at the time - basically three month's wages - so I made do with a mono-VGA monitor from a POS (point of sale) machine with some nasty burn-in.
One of the most spectacular upgrades was the SB Pro 2.0 I bought once I had a complete functional PC. I soon added the proprietary Creative Labs double-speed CD-ROM drive to that.
Once I completed college and eventually started earning an actual salary I went through a range of upgrades from 386DX40, to 486DX33, 486DX100, P1 233MMX and eventually a Celeron 300A Slot 1 machine, but soon after that I lost interest in constantly upgrading my PC - becoming more interested in Macs, console games and my full-time job.
Recently I've checked all the stuff I still have. Being dead-poor at the time I sold most of my older equipment to fund upgrades, but I do still have a few things that work. That 80286 motherboard still boots up and there were certain other things I held on to for sentimental reasons like my 2MB Matrox Mystique card and my SB16 with Yamaha DB50XG.
Only recently have I started playing around with Commodore stuff as the brand was pretty much dying out here by the time I had the cash to start playing around with computers.
