I can get the rainbow screen effect if I look at it a steep angle. The 49g is in nearly pristine condition, I inherited it and don't use it too often. I do most of my programming and maths on my TI calcs so I can't say the same for them as far as condition.

Think I fixed the image.
I've only written a few user rpl programs. I don't have the link cable so I haven't done anything in asm or sys rpl.

I just stumbled across this topic and figured I'd share my collection: TI-89T x2 (one with a gray faceplate, one gold, both HW4) TI-84+SE (48k ram) TI-30XIIS HP-49G

Wait, so the ASIC actually divides the clock for cpu speeds 2 and 3 if you replace some 0 ohm resistors? Any idea if it's possible to do this with a TA1 ASIC? I once replaced the crystal in my M revision 84+SE with a faster one but the lcd didn't update at all, current draw indicated the calc was working though. It all returned to normal when I put the old crystal back in. Why would TI have support for ~25 mhz in the ASIC and not enable it by not populating some resistors?

Do we have any idea how the lcd driver works yet? Like if there's still a 10us delay? The z80's that I have (manufactured in the mid 80's) start to do weird things when I clock them past 20Mhz. If the ASIC still works the same, I can get my calc to go from 15.6Mhz to 16.2Mhz by disabling the memory delays.

The date code on the ASIC is in 2006. Will all 84cse's have TA3 ASICs?

I'm restoring the original page with that exact code  The crashing went away when I restored the data wikiti mentions. I was about to ask about app crashing but that bcall fixed that. Mathprint, not that I use it, acts weird after I destroy all of its data in the extra page. To disable it, do I have to do anything else besides reset 5, (IY+44h)? Hold it, you can't map RAM into $4000 on all calcs (notably the Pocket versions, since we're talking 84+)
I wouldn't put it passed TI to screw up that badly

In an Axe program, I'm using page 83h for storage. I'm using about ~14k of the page right now. What do I have to reinitialize or restore when exiting the program? Right now I get ram clears on exit but that's expected because I'm not restoring anything.

Wow, I just stumbled upon this topic. have you tried grayscale? 83+ style 3 level grayscale looks good on my NXT.

Yeah, that's what I thought with the messed up ram clear screen. I resent an os and it worked. Does the tios only trust the vat even when it writes to os flash sectors?

I corrupted my VAT while messing with random sections of RAM. I was going to run calcsys to see what it said and then cause a ram clear to get back to normal. I accidentally launched zstart instead of calcsys and made the mistake of trying to exit. I think zstart tried to archive its appvar but failed because of the corrupted VAT. My calculator boots into the boot code (ON+DEL) just fine. Booting with ON+Clear and ON+Vars and both simultaneously just shows the ram clear screen and then crashes. When displaying the ram clear screen it only shows the 'R' in "RAM Cleared" below the calculator model. I'm using a TI84+SE with brandonW's patched 2.53. Is there any way to copy/fix my archive or do I need to do the ON+Mode flash clear/os install.

He's wondering what takes so much RAM. For one thing, the emulator code is pretty large, and it needs a bit of space for the dynamic recompiler. In addition, the entire GBA ROM needs to be loaded into RAM, which is the main issue.
Oh, I forgot about the ROM needing to be in ram. And wow, a dynamic recompiler. What kind of speed do you get with overclocking?

I ran project 64 on an old 800 Mhz Pentium 3 based computer yesterday to see how it would perform. It was really slow. The nspire's lack of 3d hardware would make performance probably less than 1 fps. The GBA has like 256k ram and 128k vram AFAIK. Why doesn't the GBA emulator not run on non-cx nspires?

According to the datasheet for the NOR flash, the WR pin is on the edge of the package. Is it possible to reach that pin with a wire or is it too close to the board surface/underfilled?
