I wouldn't mind winning a ti-89 titanium. I have only ever written math programs, so this is incentive to start writing some games.

Who wouldn't mind winning an 89T? I've written some games, but they're all pretty lame, so I won't be entering. Anyway, I'm busy working on a memory expander for the 83+ SE family.

I think the keyboard might be pretty nifty for me...

Yeah, though it would be a pain to use it with my 89Ti, link port is on the top.

Yay! Programming competitions are great ways to get people to finish projects!
Is ticalc news now going to be updated every two months?

News items are posted pretty much whenever one of the staff finds good news to post.

Anyone care to mention the Cemetech and Calchaven and UTI contests? No?

And Omnimaga contest? (there is 2 actually)

I didnt knew Cemetech had a programming contest though O.o

Arg... I didn't mean to post there.

Yup, we've got a Sudoku one going:

I forgot about that one... I was going to enter... Guess I still will, too.

Yeah, Sudoku seems to be getting really popular, so why not have a calc version? ;-)

yay over a dozen of ppl entered alerady I cant wait to see what ppl will come up with

Off-topic: it's have been a while since the last news maybe ticalc is preparing something for june 21th (10th ticalc.org anniversary)

June 22nd == My Birfday!! YAY!!!

This is an idea for a contest entry. A gameboy emulator for th ti 84+. I am awar othat there is one for the 68Ks. I figured that it would be sort of easy because they have the same cpu.

not nessisarily, the game boy probably has hardware that would have to be emulated by a CPU that is just as power ful as it. emulating a game boy from a 68k calc has the advantage that the processor is more powerful.

no,
84+ cpu = 15mhz
89/92/V200 cpu = 12 mhz

Erm, 89T HW4 is ~16MHz

Umm, sorry to say, but the processors speed in (mhz) doesn't always make a processor faster then another. The ti-84 runs a zilog z80, while the ti-89 runs a motorola 68000. The Motorola 68000 is much more efficient in doing things, then zilog z80 is. Also for computation etc., the z80 is an 8-bit cpu, and the motorola 68000, is 32-bit.

Actually, the one used in the 89/92/etc. is a 16-bit processor (someone correct me if I'm wrong). You're right, though, in that the 68k has a more powerful instruction set, and probably better pipelining and a cache and other stuff that the Z80 doesn't have.

Wikipedia says it's a 32-bit, I'll fix it if it's wrong though.

Yeah, it's 32-bit. ^Link on both post^

The m68000 is actually considered to be a "16/32" bit processor.

The m68020 is considered to be the first true 32 bit CPU within the 68K family of processors.

Ok, 32-bit then, I was wrong.

The 68k has 32 bit registers but a 16 bit Arithmetic logic unit. This means a 32 bit add instruction uses the ALU twice, so 16 bit math is twice as fast as 32 bit math. And the data path to ram/flash is 16 bits.

The pipelining is really simple. It can fetch the next instruction while executing the current one.

There is no cache.

The CPU in the Gameboy is a modified Z80 -- if my memory is correct.

Your memory is indeed correct. It's _heavily_ modified though.

users benchmark reported less than that. much more close to 13mhz than 16mhz... I think this need further analysis

You forget however that the MC68000 processor is 32-bit while Z80 is 8-bit, and that the 68k's have almost 8 times the RAM the 83/4's do.
