Hi
So I have acquired a 1050 drive. Doesnt seem to respond to my 800xl at all, no boot errors, the power light comes on but doesnt respond in any other way
a few observations and questions if I may please ask for help?
There's lots of hard "glue" around the big 3 caps at the rear of the board that I assume is leaking electrolyte (?)
the 3 caps are 2 x 35v 6800uF, 1 x smaller 25v 4700uf. Are there any other caps I should change or just those? I had measured 12v and 5v on each of the voltage regulators, but the glue stuff-can that only be electrolyte?
No wonder it didnt work though, I took the rf shielding off and found a loose 3" x 2" pcb rattling around inside! has a 6502, an eprom and a few other ICs (see pic).
what is this board?
which way around should it be re-fitted! eprom to back,or front?
thanks for any help![:)]()
