Confirmed: another Pismo (the last of the G3 PowerBooks) will be joining my small collection of Macs. It's being provided by the dear friend who also gave me the Pismo I currently have. This one will have a 40 GB HD installed, the original options were 6, 10, 12 or 20 GB.
My current Pismo has an internal fault preventing it from booting from an external drive. But I have a FireWire CF card reader & I use that with the OS (Tiger/OS 9) on a 32 GB CF card. It works quite well.
In addition the screen is odd, it starts off as pink but soon reverts to the proper colour gamut.
The "new" Pismo has is "pink-free."
