Hi, Does anyone happen to have copies of any of the following documents? - Generic I Programming Specification (Signetics) - Generic II Programming Specification (Signetics) - Programming spec for the 74S*** fuse PROMs (National Semiconductor) - Programming spec for the 6*** series PROMs (MMI / Monolithic Memories) - Programming spec for the 27S*** series PROMs (AMD) - 76** series programming spec (Harris) - also datasheets (or at least pinouts) for 74S, 6***, 76** and 27S PROMs I'm trying to build a PROM reader/programmer, and I'd like to make it as versatile as possible. At the very least, I want to program 82S129s with it, but programming them is rather difficult without the specs for the algorithms. I've already got the Generic I spec, but my copy is incomplete - it covers 82S129s and I suspect it was probably included in one of the Signetics databooks at one time. Of course, not having access to any databooks older than 1997 makes it a little difficult to track the info down...
