I've found someone with a copy of the schematics for the 4808. It is a physical form, so they would have to taken to a copy shop to be copied there. Would anyone be interested in chipping in and donate to help fund the cost of getting these schematics copied? I know I'm not the only one who is looking for more information on the 4808!
If you would be willing to donate some cash money towards the cost of getting a copy of the 4808 schematics, please send me a PM or make a post here and lets see how much total we can accumulate!
