Altirra run fine in Wine plus Mac OSX
just in case... 
what is the right setup to have source code and debug stuff setup correct and useful with MADS/WUDSN/Altirra?
any advice in terms of the debugger features I missed? my one does not show source code labels in disassembly... and most of the time I am using only simply memory dump but any tricks here much adviced.
I'm gonna try a "wine bottler" setup tonight - I'd really like to ditch my atom based Acer laptop and stick with my MacBook Air and 27" iMac, so please post any info you come across. Also VMWare Fusion works great for any windows stuff at the expense of turning Apple's end to end experience into a steaming pile of horse manure

What would be cool is a 7.16mhz 65C02 with VBXE crammed into an XEGS, and 64K of ram with a CX-78 controller to get that authentic gaming system feel.
Wait, it's ALREADY BEEN DONE
Proof the Atari 8-bit could've have competed with other game systems in the 1989 era - you're welcome

Okay, so after reading multiple posts about a 32ns window at 14MHz, I am looking for a 7.16MHz 65C02. I'm seeing a lot of floppy controllers clocked at different frequencies on eBay, so which might work best in the Atari 800?
-
Any update on this CPU? I noticed earlier in this thread the availability of a development kit, but I can't seem to find it now.

Hello fibrewire,
Yes it's a standard 6502 and can be changed with a 65C02 (or a 65C816 when a few pins are changed)
It will give the advantage of more instructions.
But the higher clock speed will not go. Only if you don't need any display.
And at a little higher speed, the memory will not work anymore. Nor will the rest of the chips on the bus.....

I wonder if I can slap a 14Mhz 65c02 in my 800 and display with a Bit3 80 column card. Only one way to find out!
-
I noticed at least one person on the thread was confused... the 65C02 is NOT the same processor as the 6502C!! Don't get them confused! The 65C02 was a new version of the 6502 that got rid of all undocumented instructions, replacing them with all new instructions, like more push/pop opcodes, and bit instructions. The 65816 is based on the 65C02, not the 6502 or 6502C.
Were there any major differences between the Atari 6502B and the 6502 used in the Apple ][?
-
I have an Atari 800 with a cpu card - isn't this just a standard 6502 CPU? Can't i switch the chip out with a 14MHz 65C02?
-
it wouldn't hurt to try that MPI mechanism inide another MPI drive.

i was running my original atari 65xe with 27mhz master clock giving around 31khz horizontal
on standard monitor screen was doubled (two copies were next to each other) so i guess if i had VGA then then it would look normall
i didn't run it for long, just checked if that would be possible at all
Or you figured out a way to double the display resolution of the Atari 800 - i wonder if this is similar to the Apple II double high resolution mode?
-
I remember seeing an article circa ~1996 involving a Macintosh Color Classic and liquid nitrogen to over-clock the cpu to somewhere around 1GHz speed. As this is incredible, I wonder if this is even possible on the Atari 8-bit line. It would make for an "unorthodox" upgrade - an incredible speed boost while keeping the 8-bit as original as possible. Hopefully all chips involved in being cooled are of the CMOS type, as I don't believe this idea is feasible if they are NMOS chips.
Any ideas?
-
This thread is going to repeat the infamous locked thread from a few years ago I fear.....
I don't think so, because this conversation also includes a comparison of memory addressing between the Ricoh 2A03 used in the NES and the Sally, and graphics similarities between the NES and C64.
well, NOW it does

-
Pardon my ignorance on the subject of CPU implementation and memory constraints, but after seeing Bob's 7.16MHz 1200XL run FJC GUI, a question pops up. Why was a 14MHz 65C816 chosen instead of a 14MHz 65C02?

I always have trouble finding rom images for the Atari - luckily there is the emulators.com site, and this zip file located HERE

All they're gonna find is an I.O.U. from some guy in Venezuela that's been selling tons of new-in-box merchandise back to us for the last several years

There is a download for the BeagleWrite editor at that link AtariGeezer posted

Someone familiar with Apple II could load it in an emulator and post a video...

Curt Vendel or Christopher Strong may know

Well, here's how it looked on a 65C02 CPU Apple II with 128K banked ram

The game physics of this version seem to be dead-on accurate to the original NES version, but could definitely use some better graphics...

In Altirra use 600XL/800XL with 64K memory size
Good Luck!

Finally I can ask the question I've always wanted to ask:
Phil, did you hate Xebec drives or controllers? I've always wondered why you chose the name "City of Xebec's demise"

It's been a hectic past two years, thank you again Claus!

What was it and PIctures!

Pictures?

I used to be like you guys, thinking that legal filings and the like we're costly and expensive. Then one day a guy convicted of multiple federal felonies came to work with me at my old company, and I learned that finding the right forms and filing things is not only easy, but there are fee waivers for people who can't afford to file stuff. He was a "jailhouse lawyer" a system which allows regular people with no law background to practice law given a person is self-taught with experience in the legal system. It functions much the same way that open source software works. If you know it, you can do it. There are even manuals published by prominent members of the law association at can assist people who feel helpless in taking action. I have a few years of experience in filing multiple types of court documents, but nobody will use google and the court system the way someone with proper motivation would.
I would of course be happy to point someone in the right direction for filing in the US where the violation is taking place.
