Hey guys, Specifically those with APU1...i had my 7747 modified with a ZIF socket. What exactly do I need to do to the chip to work as a 24 pin? I did see the post that Dave made with the 5 legs jumpered on the 28 pin ZIF socket, but am not sure if that applies to what I need. I HAVE moved the jumper in my APU1 to 24 pin. And once modified, howmdoes the chip need to sit in the APU1 for programming. Tried to emulate, got a steady CEL light.
There should be no PROM in the socket of tye APU1 during emilation.
You can't program the 24 pin PROMS using the APU1.
Programming the 27SF512, you place it in the lowest part of the socket with the number 1 pon pointed towards the handle.
The man who says something is impossible, is usually interrupted by the man doing it.
Didnt have a chip in it when I tried to emulate. I have a 27sF 512 jumpered, like the adaptor in Daves thread. Just wonder what I am missing about this.
I did trim the 4(of 5) jumpered pins so they dont plug into anything.
Is there something in TP5 that i need to change as far as start and finish Hex Addresses, or chip selection?

The offset should be automatically selected when you select the bin.

I found a link with the APU1 information on the Moates.net website: http://support.moates.net/2008/09/17/autoprom-apu1/
I wonder, does the APU1 need the USB driver installed? http://www.moates.net/browse-product...-download.html

Thanks Dave, Yes, it does need the USB driver...wont work without it.Originally Posted by dave w
Setup is just my issue for now, it was set up for 28 pin chips on the TPI. I just want to make sure I am modifying the chip right. Tried programming and emulating yesterday, got blinking and steady check engine light.
I have it set for the 27sf512, do I need to set it to something different since the jumper was installed?
These are the issues I am having.
1)verify chip is blank=chip not blank
2)erase chip=erase successful.
3)check for blank again=chip not blank....WTF!
4) verify chip with buffer=NOT MATCHED.
ready to throw in the towel.
