My TL866 can test the 74XX and 40XX logic chips to see if they are good.

I've got a TL866 as well and will bring mine.  Do you use their Windows software or something else?  I use minipro in Linux for PROMs and flash, but minipro doesn't have chip-testing capabilities.  Alex J. & I also have another tester, who's name I forget, which can test TTLs however. Alex & I also have Neoloch Inquisitors, which can test many common SRAM and DRAMs, as well as PIAs and RIOTs. With multiple testers, hopefully we can knock out the testing easily. -Jonathan
