Hi, has anybody done subj.? Or F8? Are the schematics available? I don't count Cuttle Cart, I mean simple PCB with 16k eprom and some stuff around.

XFD - DCM - SCP - ATR conversion could be performed by my ACVT program. exe/bin/com to ATR by Ken Sider's Makeatr. My program ADIR could do it, but it's commandline only, no gui.

Hi, to be more precise, you don't have to allocate any memory. Just do $d5xx accesses and you're done (just in case you don't need any long memory buffers). See Rtime8 info.

So, this is not a problem with disk images, rather with data on disk images. Does my program ADIR list anything? You may also send the images zipped to my email, I may take a look at it.

Hi, maybe it's possible that you have DD disk with first three sector lengths == $100. Such should have length of $80. You may try my program ACVT which does convert/repair such images. http://jindroush.atari.org

Password is SLARTIBARDFAST and the game is know to be buggy. There's a corrected version out there, though.

Hi, can some kind soul take Hardware manual for Atari800 and check the pinout of the right cartridge slot? The pinout as given on my page is definitely bad, especially pin 1 should be different. Scans of Hardware manual on the internet are completely unreadable for me. Thanks,

I finally solved that, stupid me! So command 2 is reg2 * reg0 -> reg1 (hi), reg2 (lo), multiplication Command 1 is reg1 * 256 + reg2 / reg0 -> reg1 (remainder), reg2 (result), division. If there's division error (overflow, div by 0), reg3 is set to 1, otherwise 0. Maybe the error does also set other registers, but I didn't care. I emulated the behavior and the game works fine. Cartridge is called SuperCharger, was produced by MPP/Supra. Game is loaded from disk and is called Assault Force.

Hi, this chip is embedded in a cartridge I don't want to open. I know it's a math chip, has 4 registers: Input: 0,1,2 are for input, 3 is command. Output: 1,2 are output, 3 is status. I know that command 2 is multiplication of reg0 and reg2, result is stored in reg1 (hi), reg2 (lo). Status is probably 0 if ok, 1 if error. I also know that there is command 1, but I can't decode it's behaviour, it doesn't look like division... Does this ring a bell? Cartridge was produced in 1984.

There are only 2 versions of Choplifter. One is old 1982, in gr.8 which needs NTSC artifacting to look good. Then there's XEGS version in gr.15 (probably), screenshot is attached. All the other ones are hacks.

My personal list says: 1982 Chopper Rescue 1986 Conflict In Vietnam 1985 Crusade In Europe 1985 Decision In The Desert 198? F-15 Strike Eagle 1982 Floyd of the Jungle 1982 Hellcat Ace 1985 Kennedy Approach 1983 Mig Alley Ace 1983 NATO Commander 1985 Silent Service 1983 Solo Flight 1982 Spitfire Ace 198? Top Gunner: Hell Cat Ace/Mig Alley Ace/Chopper Rescue 1983 Wingman Unsure: AcroJet Air Rescue I (re-release of Chopper Rescue)

You should find it on my site.

Hi, doesn't anybody happen to have *.lbr for Eagle for Atari 8-bit (also consoles) cartridge edge connector? thanks,

I can't guarantee that, but it's 27128. See http://www2.asw.cz/~kubecj/achroms.htm

Hi, how to make RGB cable for Commodore 1084S monitor? There is DSub9 connector on the back side. I need to know: 1) Can join all video grounds together ? No problem with it? (also for standard scart cable) 2) Should the monitor be in ANALOG or DIGITAL mode (I assume ANALOG) 3) Which sync signal to use and between which pins it should be connected? I have descriptions of all connectors, I just don't know which sync to use...

Re-read my post. I wrote 'officially released'. None of the soft you mention was released and in most cases, is unplayable *CENSORED*

All 'official' releases but two were 1) released officially by Atari on 8bits 2) converted by Glenn. The two remaining are 1) Meteorites 2) RS Baseball I modified RS Baseball to work on my 8bit atari, but I gave up when I got the overlay (too complicated controls, would be unplayable on keyboard).

Hi, Few weeks ago I asked here for some info about mysterious AMY music chip from Atari. Because there was almost no info about it, I started a hunt for the info. I was lucky to get contact with all the developers of that chip. You can read more on my site (see sig). Go to Atari/8bit - Hardware & technical info/VLSI chips/AMY. (I'm not putting link here intentionally ).

try #2

#1 for me

Don't try APE, try ACVT. You'll find it on my page. (It needs dos/win and commandline options

You did something wrong then. They're exactly the same. To be exact: 8 banks, last of them hardwired at A000-BFFF. I think it's clearly described on my page (http://jindroush.atari.org/acarts.htm). If not, let me know, I'll try to make it more readable then

Koronis Rift?

No.

There are no separated RGB/vsync/hsync signals in atari computers. Maximally S-Video. you've got to find some external device.
