Programming an Intel 27256 (PLCC)

[REACTWSCC1]

We recently upgraded our programmer to the 448Pro2 from an old DATA I/O programmer, our legacy program for this device is in a .PRM format, how can I use this program to load onto the 27256. It is a HEX Space type of file, if that helps.

Hello REACTWSCC1,

Our software will automatically detect correctly formated file fornmats and load them into the buffer accordingly.

Please select the Intel 27256 device in the software and use the Load dialog window to load your programming data:
