identifying PC Simms

Don't bother, they're totally worthless - I'll take 'em off your hands for you. :-) Seriously, I don't have much left that uses 30-pin memory, but I do have a few - including one board my only reason for keeping is that it's got lots of ISA slots.... I don't know how to ID them, short of something that uses them. Aren't there a few pins dedicated to describing the SIMM's size? Or did that not show up until 72-pin RAM? I have an adapter board; it has four 30-pin sockets and its edge fits a 72-pin socket, and as far as I can tell it's completely passive. I've used it in SPARCstation SLC/ELC machines to test 30-pin SIMMs. It turns out the memory subsystem in those machines is bog-stupid; if you have a broken stick of memory, it still appears in physical address space, even if the ROMs don't report it to the kernel, and you can access it that way if you can convince the kernel to map those physical addresses. I found if I partially populated my adapter board I got memory in which only some of the bytes out of each (32-bit) word respond.... /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
