[Timex/Sinclair 1000]
This is some basic information on the first computer I ever owned. I recently came across this information and figured that I would round out my computer experience, showing where I started. This was the first computer I ever bought. I bought it with money I earned mowing lawns over the summer (approximately 1979, or so)
I remember buying this computer, a 16K add-on module, and somewhere in the process I recieved a graphic module that allowed for 300x300 pixel resolution (I managed to draw a circle at one point). There wasn't a whole lot that could be done with this computer, but I managed to push it's limits pretty hard.
My wife's first reluctant question on seeing the computer was, "Where's the monitor?" With a chuckle I responded, "You connected it to your TV, and probably burn it out in about six months or so."
