Hello,
The Dataman-S3 does not support the Motorola (ON Semi) MCM68766C EPROM device.
In order to program the Motorola 68766 EPROM I would recommend the
Dataman-40Pro.
All our programmers are available from stock at all times and shipped the same day we receive your payment. They come with a 30 day money back guarantee and the 40Pro comes with a 3 year warranty.
If you have any questions or would like further information, please let me know.
Best regards,
Neil Parker
