I need help about 68HC705C8

[Gabriel_Markez]

I need read EPROM/OTPROM (PROM) in order to  program other 68HC705C8.

How can I do it ?... Can I Build a Reader/Programmer for the 68HC705C8 MicroController? would you recommend what software to use?...

I have a programmer schematic and DOS programming code available on my website at:

Hi Gabriel,

You can read all about this, along with programmer circuits in the devices data sheet.

MC68HC705C8A.pdf

which can be found here:

However if the security has been set, none of this will help you read the contents of the PROM.
