Looking for lexicon 224 service manual

hey there,
i know there is one on google. but its incomplete and the wrong revision. does anyone maybe have a schematic for revision G of the logic processo? thanks a lot

 

[salomonander]

ps: my unit has revision G of the logic processor and revision 2 of the dac. i think its a  later version and it does not fit with the hit i get on google.

in case anyone has the same version of the logic processor id really appreciate a high res pic of it.

Only have rev. D

It could be hard to find, because as far as I know the SBC card (single board computer) was not developed by Lexicon. They just use something that another company had made.

wow thanks so much for the tip. just found a brand new replacement just kidding but i might find the schematic via that lead. cheers!
