Subject: TRS-80 / System 80
Hi All
I have just acquired a System 80 MkII (distributed in Australasia by
Dick Smith Electronics).
On power up I get the LED power light ok but a screen full of random
characters, the reset switch does nothing. I've had it apart and there
are no loose connections or chips on the two main boards and no sign of
any burnt or expired components.
Has anyone had similar problems and / or knows what the problem is?
Thanks
Alan
check the power rails for good +5,-5 and +12
then check the 4116 ram chips.
when they fail they get very hot.
