As far as I remember no, it was a serial type of chip not parallel like most EPROMs. I was thinking if it would work on the 4qgx but probably not.
I have a programmer but I haven't used it in years, almost 10 to be exact.

yeah ; was wondering whether my little 4qgx would do it ....

The gq4x does support many pic and atmels. Doesnt matter if its serial or parallel.
http://www.mcumall.com/comersus/store/m ... ortICs.asp does say PIC12F675 is supported. Might just need to make up an adaptor to plug it in.

very easy to make too - a simple piggyback chip adapter would work here

The GQ software tells me its actually 1:1 with this offset, and a resistor needed only if a particular flag is set for the erase. The adaptor would only be needed if its surface mount.

Edit: Ahh I see your planning on programming it on the pcb via ICSP. Fair enough then you'll need both diagrams.

hey........can be done off PCB and dropping it in the gq4x like you've shown antus.....no adapter no ICSP
