    Last post for the night...

     

    Using the myide.sys driver for SDX, you can start atari800 with the -ide disk.img and use it with 512 byte sectors. It's the fastest so far, 56KB/sec. I rolled my own SDX cart rom with the myide.sys driver and used fdisk to partition the disk, setting the boot drive to D3:.

     

    My Pi800 project moves forward...

    Success! In the config file, the correct setting is:

    BB_SCSI_DISK=/path/to/image

     

    Once that's in there, you can start atari800 with the -bb switch to turn on Blackbox emulation, and can then follow tschak909's directions above. Unfortunately, on the Raspberry Pi, I'm seeing have the speeds he's getting. :-(

     

    (On a side note, is there any documentation project for Atari800? I had to dig through the pbi_bb.c file to get the above setting.)

    Yes you can put any 8K ROM in those slots. With a lot of clever editing of the cart's banking code and the use of multiple slots, it would probably be possible to hack MAC/65 or a similar banked cartridge in there too. There's a challenge for someone.

     

    The only 8KB cart slot in use by default on an XE is the BASIC slot. So you have three free cart slots, and the four XEGS slots.

     

    Note you can name the slots too; this helps to keep track of what they contain:

    So how can I use the XEGS slots?

    I created the disk image and added the BIOS to the configuration file. It's finding the rom because I can start Atari800 with the -bb flag and bring up the BB configuration.

     

    But, there isn't any setting in my .atari800.cfg to tell it about the hard disk. A quick grep through the source didn't turn up anything either, I'll dig deeper.

    I have a fundamental lack of understanding for the way the SIO2SD handles ROM images vs ATRs vs XEXs I'm afraid. I tried to load the Assembler Editor cartridge ROM on to the sd card, mount the image to D2 with the SIO2SD and then point to D2 with Uflash CAR1. It didn't see the ROM. I also put it in to an ATR and mounted the ATR without success.

     

    If you set a ROM to a drive letter, I think SIO2SD will set it up so you can boot that rom, and you won't be able to see it in Uflash. You'll need the ROM in an ATR file.

    No, just commands. Put sprite 1 at location 10,10. Upload background data to device and set background to the uploaded picture. Or generate the picture programmatically. then the device handles the display.

     

    Turn off ANTIC for more speed.

    I have a VBXE that I need to install, the reasons I want it are for the RGB output (I already have an ST monitor) and for 80 columns. The rest of the features are just extras. Could a product be made that just gives 80 columns and RGB out? Will it be markedly easier to install and cheaper? Probably not.

     

    The idea above of adding to an SIO2USB device is even easier. A Raspberry Pi can be connected to the SIO with four wires and a line leveler. You'd then have HDMI and composite that is not compatible with any A8 software (if someone writes the software for the Pi and the A8 that is). $30 and you have a plug and play solution. Is it useful?

    Hi, Fletch,

     

    Since the podcast, I found midi-maze at AtariMania and we've already ordered some midi-mates from Bruce at B&C to get this set up. We're going to set up a midi-maze demonstration with 8-bits (and likely ST's) at VCF Southeast.

     

    I was not aware that Lance had the actual cart. If we prove this works, then I would like to buy the cart.

     

    It would be great if you set something up at VCF East, which none of us Antic hosts are going to be able to get to.

     

    thanks for the information!

    You could just spend $100 at Atarimax and get 5 8Mb carts, then you can use them for whatever games you want. :-)

    Here's where I made the connections to the CPU on my 1200XL:

    Of course, I can't remember where each one goes, but if you're doing a 1200XL upgrade it's easier than I thought to follow the traces on the motherboard. (The electrical tape is because that pin is almost on the resistor.)

    Duh, why do I always make things hard then they are. I didn't want to solder onto the CPU directly, and didn't realize how easy it is to trace the cpu pins out to a pad to solder onto.

     

    U1MB is installed in my 1200XL. If you told me 20 years ago that I would have a 1MB Atari, I would have laughed in your face. :-)

     

    Thanks everyone!
