I am an (ex-) embedded software engineer with reasonable (but clearly not enough) hardware knowledge.
I have an ZIF socket that I want to piggy-back onto a board-mounted 80C88, so that I can either plug in an external 80C88 CPU, or an 80C88 ICE.
What is the easist way to disable this onboard 80C88 CPU so that it doesn't drive/output anything (Address/Data/Control signals) by cutting/lifting/pulling up or down one or more pins?
I'm not keen on removing the onboard device, as I'd like the option to be able to use it for test purposes.
Any experts out there - your advice will be gratefully received.
Thanks,
David.
