Does anyone know where I can borrow, rent or buy a programmer for the above Motorola uProc?

It's been a long time since I played much with HC11's, but I seem to remember that they mostly use bootloaders. Just plug in a serial cable and run the loader software.

I have just the 52 pin chip - no p.c.b. or interface.
I need to copy and program a series of 68HC711 these processors.

There are production programmers available. They aren't cheap. I know nothing about them. I only used HC11's for fun.

Dear Futz
Do you have the bootloader program for HC11 motorola, Can you please share it with us

Thanks

From direct experience, unless you have the source code (the flash access/security bytes in particular), you will Never get to the runtime code to upload & copy it.

In the fall of '10, I had a task to do the same. I thought the 711 series was early (primitive) enough to not have effective security, and spent a solid week finding otherwise. I had to disapoint the customer, but they appreciated the candor.

I use 908 & 9S08 series chips and Know that Nobody is getting My IP anytime in this century.

The most practical approach is to rewrite the project from scratch. BTDT X n, but good luck anyway... <<<)))

P.S. depending on the exact part number, they may be simply unobtainable.

If the op hasn't managed to program it after 10 years, they have probably given up.

Welcome. Many new posters don't realize how old threads are.
