I am waiting on back order for a month to get a Palm IIIc, and was wondering if any of you with any of the DragonBall EZ Pilots knows the answer to any of these questions: (I have read through the manuals, but they seem to be only at the abstract programmer level... Eventually, I could answer these questions myself, but if anyone knows sooner...) (1) Memory bandwidth: How fast can you read or write to main memory? I assume the instructions would be capable of up to 66 Megabytes/second, but I don't know what clock rate the 16-bit internal or 8-bit external bus runs... Along these lines, does anyone know what the Palm memory actually is - e.g., 2 bank EDO-DIMM w/16 bit bus, or whatever... (2) Screen Bandwidth: Is the screen just stored in conventional memory, or is writing to it different? Any idea on memory bandwidth writing to the screen? While I'm at it, where can I find the actual screen pixel formats, e.g., 4-bit mode is packed where Left Pix = high nibble and Right pix = low nibble... (3) Sound: I'm sure I'm not the first, but I'd LOVE to do 8-bit sampled sound to create multiple channels, but it'd have to be done by DMA (or maybe interrupts) because I want to do other things than just sit there playing. Has anyone done anything with bypassing the high level MIDI routines and writing sound samples directly? Is this stuff actually possible, or is the Dragon truly implementing MIDI in hardware with no low level sample access? That's enough for now - I appreciate any advice you might have, even if it's to go look elsewhere for these kinds of questions. Thank you for your experience. - Jeff -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
