This the System Specification manual written by Fred Bowen for the Commodore 65, the successor of the Commodore 64. The machine was never finished, but some pre-production prototype versions of it were sold during Commodore's liquidation in 1993.

I have no longer any sort of idea from where I got the scanned copies of this manual some years ago. If you happen to know :), feel free to remind so I can give the credit where it belongs.
