Hi, I just splashed out on the PICStart Plus so I can quickly get into programming the 12C508. The PICStart that came needs a firmware update before I can use it with C508s. A readme file suggests this is a file called PSF12000.hex, but I think there is a later one still. I haven't been able to find this file on the microchip web site. Can anyone tell me where it is hidden? Or better still email it to me. Thanks for your help, Mike Watson
