Yes, they exist. Flip a latch and the top opens, and you drop the chip in - true ZIF. I grabbed a bunch one day back when I worked at USR (back when they used to let people take home surplus), but I have no idea where they went. If I find them, I will let you know. You do not want to have to buy one of these things - they are NOT cheap! William Donzelli aw288(a)osfn.org

Ethan, I needed to do the same and so I made my own adapter. In my case, I needed a PLCC32 to DIP to burn a 32Kx8 PLCC OTP PROM, so I took a 28 pin machine socket and wired it to a thru-hole 32 pin PLCC socket. Here is a pic: http://www.ubanproductions.com/Images/plcc_to_dip.jpg Yes, you can certainly buy adapters like this (only more professional) pricey -- probably $100+. --tom At 11:49 AM 2/4/2003 -0800, you wrote:

Rumor has it that Ethan Dicks may have mentioned these words: They're out there... Some of the least expensive adapters I've found (including the least expensive programmers & SMD rework stations I've found) but still by no means "cheap" would be Xeltek -- www.xeltek.com. Had decent luck with my refurbed programmer that was <$200 and will do up to 4Mbit [Flash|EP]ROM devices, as well as PAL/GAL/PEEL/ATMEL etc... Their PLCC sockets range from $130 -> $185 (I'd seen 'em as high as $325, so that's a *bargain*... ;-) ) HTH, Roger "Merch" Merchberger -- Roger "Merch" Merchberger -- sysadmin, Iceberg Computers zmerch(a)30below.com What do you do when Life gives you lemons, and you don't *like* lemonade?????????????

I've got a couple that came with an old Data I/O programmer I bought. They're undocumented as to the pin mapping, but they definitely work with a PLCC 27C010 that I popped in. The programmer type setting is different than for the DIP version, so the mapping might not be 1:1. I will check with a Ohmmeter and find out.
