Ours was a Model I. I had to install the RAM and ROM upgrade in it to make it a Level 2, which involved soldering wires to the main board. Scared the hooey out of me when it wouldn't boot after I did the work. I figured I'd just toasted the boss's $1800 investment. I opened it back up and discovered the processor chip (a Z80) wasn't fully inserted into the socket. Since I hadn't removed it, I have to assume it came from the factory that way and the only reason it worked before is because the pins were lightly resting on the socket contacts.tcurt wrote: Thanks for the insight and advice on that anode lead! By the way speaking of wiping the dust off.. my first computer was a TRS-80... model II .. look it up it existed :)
The closest thing I had was a Timex-Sinclair 1500 that I picked up at a yard sale in my teenage years. it was a cute little thing, but due to a number of factors (including the chicklet keyboard) it was not a daily driver and ultimately ended up, like most of the stuff I had in that time period, going in the trash because it was damaged due to me being bad with my toys.Antknot wrote: Anybody but me have a Sinclair ZX81?
