  1. There was info or it was reviewed in either Antic or Analog (I forget which but don't see it in Antic archives). Seems like the company had another cart like a disk emulator or something in the same article.

     

    I seem to recall an ANALOG review. This was similar to the "Atari Zucchini" series of articles by Lee Brilliant, on converting an 800 to a printer buffer - a custom SIO cable between the parent computer and the slave 800; the 800 would act as a printer buffer and print out via the joystick ports to any Centronics parallel printer (in other words, it would act as the P: device).

     

    I also recall another cart from the same company that would have your second computer act as a RAMDISK.

     

    Anyone interested in learning to program SIO / CIO could do much worse than reading the Atari ZUcchini articles from ANALOG.

  2. I have made it to "Blue Max" but only 4th class... every time I get all the targets early and hit the bunkers in the city on the first pass I somehow manage to crash into another plane. But I still go back...

  3. I think ANTIC ran an article many, many moons ago in their "Tech Tips" explaining the 5v switch method - in fact, it's what I've got in one of my 800xls (socket soldered on top of the OS ROM, 27128 plugged in on top).

     

    That may explain why that 800xl gets flakey when I try using an Atarimax flash cart...

  4. It used to be available at the Umich archive; if that doesn't work out, I know I have a copy somewhere - the problem si that my Atari stuff is mostly still in storage, so no guarantees as to when I can find it.

     

    It's a drop-in replacement within the OS; what I did was take the XL OS, replace the FP routines, add John Harris' Hyper E:, and add a routine from Antic so CTRL-SHIFT-P would dump a GR 0 screen to P:, then burned it into a 27128 (losing the International charset in the process, but still having a few hundred free bytes to play around with). Again, once I dig out my disks I'll upload...

  5. Slightly OT:

     

    The Montreal Atari Club was named at its first meeting "The Reunion of Atari Montreal People" or TRAMP. It was intended as a joke; at the second meeting the club was renamed the "Montreal Atari Club Atari de Montreal", or MACAM. Lots of memories there...

  6. I'm interested in seeing what device drivers exist for the Atari 8-bits. I'll list the ones I know, and I'd ask one and all to add any others they know about.

     

    S: Screen

    P: Printer

    E: Text Editor

    C: Cassette

    K: Keyboard

     

    D: Disk drives

     

    R: RS-232 device (Atari 850, PR Connection, MIO, Black Box etc)

     

    G: Graphics printer device from ANALOG

     

    N: Null device, from Antic (I think)

     

    M: For the Multiplexer interface, originally from CSS

     

     

    Any other ones you can think of off the top of your head?

  7. I believe you are correct. After a comprehensive set of tests (some would say I merely played a bunch of games, some 400/800 only, with the switch in both positions. But I call it testing) it appears that one position is the 400/800 OS (with OPTION to enable BASIC), while the other is the default XL OS.

     

    Here are photos (top and bottom) of the upgrade:

  8. There is another thread at http://www.atariage.com/forums/index.php?showtopic=104682 that has scans of the Ultra Speed + OS manual.

     

    I recently found that one of my 800xls has an old CSS OS upgrade. I haven't yet had time to do any detailed poking about, but the OS ROM has been replaced by a small PCB with a socked for the old ROM, plus another EPROM with its face covered in black plastic, along with some logic ICs with their identifiers carefully rubbed off. The bottom of the board reads "Computer Software Services 1984". I'll try to open up the system again to take some pictures (the RF shield is actually screwed down on this machine!)

     

    The selector switch has only two positions, and when in the non-default XL OS position the functioning of OPTION seems to be reversed on boot.

     

    As the UP+ OS came out in 1988, and this PCB is dated 1984, does anyone have any ideas what it might be?

  9. Is there a general FAQ that explains exactly WHAT all these products are for people who have been out of the loop for years? They all sound like things I'm interested in, but would like top-down description of them!!

     

    There was an upgrade FAQ at one time, I'm not sure if its up to date or even still available?

    As the one who many, many moons ago wrote the upgrade FAQ, I can safely say that (1) it still lurks around the darker corners of the net and (2) it's woefully out of date - I'd estimate a decade or more - think back to Geocities and handwritten HTML...
