In an effort to nail down a potential replacement SWIM for my 5120, I began looking at SWIMs on other boards of a similar vintage. I have narrowed down the potential options to:
344S1029: the direct replacement, what I pulled off my 5120
344S1029-A: seen on 5126, PB100, 140, 170
343S1029-A: seen on PB100, 140, 170, 145B, 165, 180c (and I assume all others prior to the 150).
The SE/30, IIvi, LC, LCII, Classic, IIsi etc. all use the 344S0061-A, which is also PLCC-44 like the above but I'm not sure if they would be suitable as a replacement if power is a factor. My understanding is that SWIM is 100% backward compatible, even with IWC... and seeing that the PB100 / 140 / 170 are seen with two versions of the SWIM, one of those versions is found on the 5126, I'm venturing that early PB SWIMs would work just fine as a replacement on the 5120.
Does anyone have any specific knowledge about this? I haven't been able to find anything in search.
