The technology used in the 250/270 screens are older twist plane technology, not as fast as what is used in the 280 (and that was about the time I switched from R&D to managing our affiliates, and so can't remember the difference between the two...anyone remember/care about the difference??). The important thing is that there are differences in the method of driving each LCD....and only the 2300 logic board can drive any of them, the previous models can only drive the same style display as it came with originally. Donald, one suggestion would be to find a display off of a Duo 280 (the mono screen). This will give good video performance as well as a clear display using reflective light (the color screens use transmissive light...i.e. light pushed thru the screen instead of reflected off the liquid crystal itself...color reflective displays are available but not as popular as supertwist active pixel transmissive displays). You should be able to easily see the screen even on the brightest day (my old unit got used on the beach alot). One note....you will be limited on pixel depth, which is 256 greys, IIRC. Older units were limited to 16 greys......if anyone on list has a mono 280....please check this for me, believe I'm right but don't want to mislead anyone. Installation is "plug and play" by removing the color display and mounting the mono screen. Make sure you are getting the entire upper frame and screen, not just the screen itself, as the cable will be different (on the display end, not the computer end) and it is alot easier just to swap the upper section instead of components. Keep the old color display for future use or sell it to recoup the cost of conversion. BTW, a mono screen should be quite inexpensive, and mounted on the 2300 will allow use of PPC only software. If the software will run under System 7, find a cheap 280 mono and use it. It will run faster under Sys 7.X than the 2300 under OS8. Just avoid Sys 7.5.X except for 7.5.3, which seemed to fix most of the bugs. 7.6 is good, too. Andrew ---------- Duo/2400 List, The friendliest place on the Net!
