    OK, so when the Powerbook G3 2000 (Pismo) was introduced, Apple stated that the max ram capcity was 512mb (2 X 256mb). This wasn't really the true capacity that the Pismo could address, just what was available at the time. So time goes by and 512mb 144-pin SDRAM (Low-Profiles) are released. So now the Pismo can unofficially hold 1Gb of RAM (2 x 512mb).

    So, I noticed that 1Gb 144-pin SDRAM Modules are now available;

    Is there any reason why these wouldn't be compatible with the Pismo? I mean, what actually "cap's" the limit to the RAM that can be addressed? It would rule if these would work, Photoshop can eat RAM like a mo'fo. Huh.

    I wouldn't consider my reply authoratative, but I don't see any problem with it. Go for it.

    I would say no. I haven't seen anything on Powerbook Titaniums supporting anything more than 512MB SODIMMS, and the Pismo is much older than that. The motherboard is the actual limiting factor in what RAM can be recognized (unless there is a shortcoming in the OS).
