Hi everyone, new to the forum
I'm working on resurrecting an 01W.
I've got it booting up after various issues;
Power supply seems ok, (can update voltages if req'd)
Changed a few 100uF caps on the +12-12V area on the mainboard.
Some damage on underside of board due to battery leaking.
Tidied up damage, electrically seems ok now, new battery fitted.
Many of the buttons don't function and most of the leds are not lighting,
The 8 buttons left of the data slider are ok, although no leds are,
data slider ok
4 buttons on the rhs of data slider not working
All buttons under the lcd working except "H"
"PAGE +" "PAGE -" not working
The rhs number button area most work except,
"0", "COMPARE", & "RESET".
Just wondering if this is a familar fault known to anyone, perhaps a logic chip on the mb or poor contact on a certain address line etc?
Also the sequencer crashes the system when used.
Floppy not working either.
Pretty poor state, however I WAS able to load in the factory presets and all the keyboard is responding and the audio is clear, so perhaps there is hope:-) |
