Re: leg spacing on an eprom

I've always seen the '8746 ECMs to be the .6" spacing.

Re: leg spacing on an eprom

Btw, how do you determine the leg spacing on a
Chip. I googled how to find leg spacing on eeproms and nothing came up.
Thanks!

Re: leg spacing on an eprom

Chips have standard leg spacing, none that I know of have the .45" spacing. That spacing is from the socket being used. I've only seen those on the 1227148 ECM used in the '89 TTA.

For the leg spacing of a particular chip it is found in the data sheet.

Also used in the Turbo Regals and GNX. I had to make an adapter for a friend's '7148. I used some perf proto board and jumper legs to do it.

Yes, the '86 - '87 MY's to be exact. Being a 3rd gen f-body board I kept my response on topic for the board we are on.
