URGENT Powerbook 1400 RAM question

Hey guys, I'm on a bit of a time crunch here to catch an ebay auction. I'm looking to expand my powerbook 1400cs ram. I currently have 48MB with the stock ram and one expanded card. that leaves room for one more card. If I get the 24MB ram will the powerbook recognize up to the 64MB limit or will it ignore the second card completely? Will this damage my computer in any way?

From Wikipedia:

"The 1400 was easily upgradeable. System memory could be "piggy-backed" onto each other (another feature unique to the 1400), allowing for the use of additional RAM chips."

It will probably reach its max and not read more than that

64MB is the maximum memory for that model. Usual combination was 1 x 16MB and 2 x 24MB. Chances are with the additional 24MB will just read it as a 16 and shows 64MB.

Considering the processor is pretty slow, can be anything from 113 to 160MHz, the additional memory may not make that much difference. Thehy are a great machine the 1400 and reliable as all get out!
