I got my first computer when I was 5 years old. It was a breadbox Commodore 64 with a tape drive and Wizard of Wor cart. I owned original Jumpman on tape. When I got bored of looking at flashing coloured lines, I rode my bike around the block until tape games finished loading (this often took several laps).
Jumpman was my favourite game. Sometimes I would leave the C64 on overnight since the loading times were so bad but of course it had a loose power cable, so if someone knocked it, the computer reset.
My C64 was stolen when I was 8 (house was robbed). It had "Rolf Harris Picture Builder" in it at the time

A few years later my parents replaced it with an Amstrad PC-1512 (CGA monitor, 1 x 360KB 5.25" floppy drive, 8 MHz Intel 8088, 512KB RAM). It felt like a downgrade from my C64 since C64 has superior sound and more colours.
I had typed in BASIC programs on C64 but I didn't really learn much BASIC until I got the Amstrad XT. It had BASICA/GWBASIC and I made hundreds of small games, stick figure demos and a face building program (it gave you a choice of shapes and sizes for head, eyes, mouth, nose etc). Unfortunately I've lost them all now.
It came with Bruce Lee (I got really far in this but never finished since the electric ground parts just moved way too fast), Tag Team Wresting (I got really far but it always crashed before I won the title), The Trading Company (finished many times) and The Dam Busters (it was hard at first but I bombed that Dam eventually).
Alleycat and Digger were some of my favourite DOS games. I've ported (badly)
Digger to
DS,
PSP and Wii.
The first Amiga that I owned was a second hand 600 with no hard drive and the internal floppy drive rarely worked. Fortunately 2.04 KS let me boot off an external floppy but many games needed to run/boot from DF0. Transplant was one of my most played Amiga games but that could just be because it was multiplayer and I didn't have many games. Tanx n Stuff, Dogfight and Croak were all fun. I made animations with Fantavision by Broderbund (amazing program, very much like Flash but at least a decade earlier). I might upload them sometime.
I've had many Amiga 500s over the years but I'm down to one now and I will be selling that. I'm most attached to my Amiga 1200 with a Blizzard 1220/4, PCMCIA ethernet and 430MB 3.5" hard drive (I'll put a 4GB CF in there soon).
