and I could add the fact that the TI-83+SE have been discontinued so ppl who want a z80 calc with 1.5 MB of archive have no choice but choosing the 84+SE
I would like a 84+ (maybe a TI-87+?) with memory mapped display me too. however I am wondering if for example durk and Jim e gpp would still be compatible with them since the LCD driver would be faster?
No neither Ducks or Jim's grayscale packages would work if the display was memory mapped. But the thing is there would be no need for them in the first place as with memory mapped displays (as the name suggests) changing a bit in memory will change a pixel on the screen. Thus you could use the old switch buffer trick and it would work fine without any flicker.

yeah the 2 buffer trick told in the asm28d. Thanks for the info. I was just wondering because if TI would change the LCD driver ppl would have to update all their grayscale games (except if they are in BASIC)
No, if they added memory mapping everything has to be ported. It's a major change. Well unless they mapp it to a specific ram page and keep the driver, but i don't know if any driver could do that.
So in conclusion this would be a different calc? Hmm, well, I think they should make an upgrade to the 86 (with flash support). 96kb of ram with 480 KB of arc memory would be cool
Well, it would suffice to let an interrupt swap buffer pointers (if the driver supports a pointer), and run this routine on the highest frequency possible. This wouldnt garble (smart blend) the pixels though like Jim's or my routine, but I wonder if you would need it with such a high freq. I heard those TI85/86's are quite flickerless.
That is the main reason I like the 84+se more mem. On mine I have desolate, wolf 3d, sim city, starcraft, gemini, alien breed. I still have over 1 mb of mem. I'm still a noob to calcs but I do know the 84+se is the same as the 83+se, just looks different.
