Repair Sinclair DM235 DMM
Hi,
Can somebody please give me a hint where to find a circuit diagram or a service manual for an old Sinclair DM 235 DMM (for free)? When switched on only one digit is active displaying a random number. Additionally I'm searching for a datasheet of AY-5-3507 display driver (?). Any help is really appreciated. Best regards Reinhard |
