Bricked spectrum zx 128k and 48k

[Cyber-Mav]

Ok this was many years ago and 2 of these computers i had got bricked by pulling out the joystick interface while they were powered on.
After that they showed a noise screen when turned on like you got on old crt tv when it got no signal.

I can't remember this proper since its well over 25 years ago but i got thinking about it and wanted to know what happened to the units and would they have been fixable? Both were binned.

dang, not sure but this issue must have been common if people mistakenly pulled out the joystick interface card thingy while it was powered on. i cant seem to find info on it though. very curious to know if it was fixable.

I did the same on my 48K+

it turned out there’s a see through fuse in them which blows when you do this. Replacing that fixed it for me.

wish i had know about this fuse back then.
