I get my 2732's from bgmicro.com. Theyre all pulls, but for $1.75 thats fine
w/me. I've had maybe 5 in 100 that wouldnt burn. >>
I ran a blank check first and it checked out okay on all five chips. Also
burned a 2732A National Semiconductor in between these five with no problems,
so I'm pretty sure the burner works. Could it be they sold me a bunch of bad
chips? I have ruined other chips by erasing too long.
