- I don't see any point in offering a 1-bit LCD model. The video interface
- for that machine is not significantly cheaper than the current 4 bit
- interface. The VRAM needs to be bigger, but that's about it.
-
- All PowerBook with video out support the 16" display. My PB160 does it
- splendidly. The difference is that the Duo Dock (not the Duo itself) can
- display 16 bit color on the 16" display. The power requirements of the 16"
- display at 16 bit color is beyond the current PB power budget. Even at
- 8 bits per pixel, the PB should be kept running at 16Mhz to reduce heating
- and conserve power. More VRAM would take more power and generate more heat.
-
- A PB180 with a fast static RAM cache would probably run much faster than
- a 40Mhz 68030. I seem to remember that the PB180 has at least 3 wait states
- to RAM memory and more for ROM...

- As I said, the 1 bit display is not really any cheaper than the 4 bit display.
- A duo with a 16 bit data path and running at 16 or 25 Mhz would be more
- interesting, although the savings are questionable there too... It's possible
- that a 16Mhz duo with a 16 bit data path would be successful, but I doubt
- Apple would have time to get the R&D money back before the machine was
- obsolete.
-
- Maybe you could strip out the SCSI from the cheap Duo, although since Apple
- already has the serial/SCSI combo chip, they probably wouldn't gain much
- from it. Mostly it would be troublesome to support.
-
- I agree that the price has to go down a bit before students will really get
- interested. Fortunately time will take care of that. There's no need to
- design a lower cost version.
