Kit 8048 with 16C505

I recently bought this kit and it is working fine.
However, I would like to program the PIC16C505 with it does anyone know how?
Do they have the appropriate files to make it work?
I have tried modifying the files but keep getting the error
Write Error OSCCAL at 03FF

You could move to the PIC16F630. It is fully supported, uses flash technology and it is pin compatible with the 16C505

Yes I realise this now but already have a number of the ‘older’ 16C505 I would like to use.
Thank you
