How have you tested them? In stacked pairs? Stacked with other modules? Singly? Seems odd that there'd be trouble with a single 24MB module. But the stacked module problem is pretty well known. Seems there's an unsolvable problem with some 1400's - perhaps a memory controller problem? - wherein they can't use the 4MB or 8MB "Apple slot" module installed above the 8MB motherboard module. The result is that they cannot have more than 56MB installed. I had one of these - it was a 1400c/166 - which was a jewel of a PB, except for the 56MB memory limit. It worked great with 2 x 24MB or 1 x 16MB + 1 x 32MB stacked modules. Didn't work with 24MB + 32MB stacked modules. Worked fine with a G3 upgrade too.
