I am hoping someone has schematics for Spectrum. I have a long dead one I have been slowly bringing back to life. IPDB has the manual but no schematics.

I finally got it to boot, but it seems to have at least two locked on lamps (likely shorted closed lamp transistor). I hoping someone has a schematic so I don't need to try and figure out which one(s) it is on the TWO lamp boards.

Also, I am sure I will need it for something else for this project.

I will post an update if/when I find a copy of the schematics. So please, if you are reading this I still need a copy of the schematics for this great, unusual pin.

Thanks in advance.

Thank you for the great photos. Just what I needed. What a mess of lamps in this pin!

Looking forward to playing my first game of Spectrum.
