Grayscale Possible on Hardware v2.00!?
Posted by Nick on 23 December 1999, 06:48 GMT

Scott Noveck and Niklas Brunlid have apparently fixed the problems with grayscale on hardware v2.00 calculators. Scott sent me an email with some instructions on how to use these (along with a lot of disclaimers and such) - attached were the libraries. I packaged them all into neat little .zip files (with the email as documentation) and voila. You can download each file here:
Gray4Lib for the TI-89
Gray4Lib for the TI-92 Plus
GraphLib for the TI-89
GraphLib for the TI-92 Plus

Here's the email. Enjoy! :-)

Subject: Grayscale for HW2
Date sent: Thu, 23 Dec 1999 00:12:37 -0500

Here ya go - no need to put my name in the HEADLINE, of course (and wherever you put it, also mention Niklas Brunlid), but here's the relevant info:

graphlibHW2.89z - graphlib for HW2
graphlibHW2.9xz - _exact_ same file as above, but renamed to .9xz
gray4libHW2.89z - gray4lib for HW2
gray4libHW2.9xz - _exact_ same file as above, but renamed to .9xz

Some quick notes:
1.) These should ONLY be used on HW2 calcs - HW1 calcs should keep using old libraries (they CAN use these, but the old versions are faster and flickerless). To check your hardware version, go to the home screen and choose About from the Tools menu (F1) - if it is not specified, then the calc is HW1.

2.) These flicker a lot. Understand that this is hopefully only a temporary fix and is NOT the same method used for greyscale on HW1. Due to hardware limitations, it's a lot slower and will flicker - a small price to pay to get the stupid thing working.

3.) Most, if not all, programs using these greyscale routines should now work fine, minus a little flicker.

4.) gray4lib source is included for programmers using their own greyscale routines. tios::PortSet is undocumented, but it is called as PortSet(*DUP_SCR+4, WORD x2, WORD y2) and causes all tios routines to draw to the buffer at DUP_SCR with coordinates (0,0) through (x2,y2).

Am I the first comment? Hope so.

All I can say is that it's ABOUT TIME. I haven't looked at them yet, but it's still nice to see some people working on the problem. Now if they can only fix Sonic Misadventures...

Kudos to all those great people! Saints in my opinion!

Read the news item I posted right before this one. They did, but it doesn't work on AMS v2.03 yet.

I didn't read that one till just now. Forgot about it 'cause I was busy writing the comment to the first one! Nice to know. But still, Plusshell doesn't really work on my 92+ either... freezes up on the explorer (is that what it's called?) screen. I'm a DoorOS person myself.

What happened to the "first comment" rule? I had gotten wind somewhere of you guys wanting to dump posts that boasted about them being the first comment. Has everyone been out in full force so you decided to drop the rule?


PS I am not doing this because I want to make a "first comment" post as soon as you make a news item of a TI-92 Plus having an unknown extra 650MB of RAM plugged into the link port (aka a CD-RW Drive)

Heh I really feel sorry for all HW2 owners, but I'm glad that they'll at least have a "temporary" fix such as this to make grayscale games playable. It's a shame TI made such incompatible calcs under the same name, especially after advertising that you'd never need to buy a new calc because of flash rom upgradability.

Finally, grayscale suppprt. Not fair though: Now hw 2 users get gray and the additional memory of AMS 2.03.
I always got grey on my hw 1, but I want my additional memory.

Um, actually, the fix won't work on AMS v2.03 yet.

But anyways. is it really THAT big a deal? Heck, the extra memory isn't that big a deal on the TI-89 because 500K is a WHOLE LOT! =)

It's no enough!!! streetfighter takes up more than the full memory.

Most ancient PC's have more than that, like, um... 640k of Conventional Memory, and a 720k floppy disk drive!

Yes, I would also need the source code, if possible, because Bigdyna is using its own grayscales routines, and it would allow me to fix it quickly...

Can I now run kernel version 0.6 and actually successfully play AMS 2.03 games? I have hardware 2.00
The only problems were the libraries?
Do I still need to do the launch thingy?

This is great, just in time for Christmas. Now I'll have some games to play Christmas morning.

Welp, good news for, you 89 users =)

I am accessing this from school believe it or not, on a crappy iMac :/

We're having a party in biology and we get to do basically whatever we want.

Macs are so slow when connected to an at-ease network. And some idiot believes "Virtual memory takes too much hard disk space, so let's disable it!" I have found that a G3 on an at-ease network is slower than a Macintosh LC on a different network. (And to make matters worse, my school finally realized and fixed the bug that allowed programs to be run from floppys or documents panels!) But iMacs are an abomination, they are not only slow, but have Internet Exploder built in, and are missing the break, printscrn, Insert, Home, End, and even the frequently used Del button! (The school has a hidden supply of gray graphlinks BTW)

I don`t know much about calculators, but is Grayscale possible on the TI-83 PLUS.

If not, Why Not?

From what I understand, Greyscale involves flickering pixels on and off very quickly. So basically, on the 83, you'd put a "picture" on the screen or whatever, and blink it on and off very fast to make it APPEAR to be grey.
The 89's 68K processor can handle this flickering much, much better than the 83's Z80 processor. The most greyscale I've ever seen on the 83 was three or four shades, I'm not sure. There was obvious flickering, 'cause you could see it 'blink' every now and then as it's flickering. Whereas on the 89, some games run on up to eight shades of grey, and don't flicker at all.

Ummmm, hehe. The reason the 83 doesnt do greyscale so well is that the 83 has a lcd driver, whereas the 89 has a memory mapped lcd.

Look in the file archives for somthing called gpic83, thats a simple little greyscale image viewer. Flickers a whole lot, tho.

GPIC was made by my friend Paul M.
He's also 'coaching' me in assembly.
We go to the same school, but he's one grade higher than me :þ
