Hi Jason I am stretching the capabilities of the VAQ and think that I have reached the end. I am trying to get a machine code loader to work within VAQ, but...
Hi Martin, I'm not sure, but isn't this a stack problem? The bootloader was written for 16K+ and 8K+. There were always two seperated RAM areas and the stack...
Hi Harrold, ... But look at how far the corrupted memory address are apart. If it was a stack problem wouldn't the corrupted addresses then be in sequence? ...
Martin, I added the following line to the LD16k program: 190 DATA 237,115,40,40 : REM LD (12328),SP This shows the SP as character 187 and 255 in the screen....
Still another tought. Is the Software lock, I/O $FF (out) in the simulator implemented for RAM also, or only for ROM? I will do some testing. Keep you...
... I found a message from emucompboy, dated Thu Dec 22, 2005 5:25 am: "I think that the real Aquarius uses the cartridge scrambler on RAM. The emulator sure...
Hi Harrold / James, I've uploaded a file called LD8K-bad.zip This does the same thing as LD16K, but it will load a 8K ROM. I've converted the ZEROIN.BIN to...
Martin, For testing I added the following line to my LD8K program: 190 DATA 49,0,64 : REM ld SP,$4000 This is a save value for the Stack Pointer. As you will...
... I haven't had a look at that program, but I can tell you that compared with some other computers, the default Aquarius tape format is less efficient. It...

... Yeah, it was crashing the BASIC stack, which abended the loader, and trashed memory. One way to deal with this would be to poke the top of RAM pointer...
I've been following the posts regarding the VAQ cassette loads with interest. Is the goal to make all carts cassette loadable? That would be great for those...
... would ... Um, someone would have to make RAM cartridges that lived in the range $C000-$FFFF. Those were a homebrew thing, back in the day, y'now, no one...
... Thanks for both your suggestions. They both work on the 8K program, but the 16K still fails. There is a slight difference in the 8K and the 16K code (there...
... I still think the scramble code is the problem. The emulator doesn't scramble RAM, only ROM. This differs with the real hardware. The reason Zero-in loads...
... Since harware always comes at a premium, I guess I would be hoping for hacked ROM images which could support a standard Aq with RAM pack. Now, a 1541...
Looks like I need to check my real Aquarius's behavior. Were you able to run 16K cartridge images from your homebrew RAM back in the day on the real Aquarius?...
... That would be ideal indeed! But difficult as you have to overwrite the ROM bios needed to operate 1541. ... Depends how you calculate the memory. Mattel...

Hey folks, I am moving at the end of the month so I have to reduce my collection. I am selling an Aquarius among other things if any one is interested. ...
After a nail biting wait of 71 days, the Ebay package finally arrived. I have been trying to get Extended Basic and Chess for many years. I was disappointed...
Hi Jason I had the chess game as a kid. From what i remember the box I had was a mattel box with the main picture on the sides and text on the rear. i swapped...

You all probably know that I have at least 15 Aquarius cpu's. I brought only 2 with me here to Japan, and have acquired a third (Euro model) from the recent...
