What he said

ANALOG computing had a program called "The Streamliner" which would take binary files made up of a series of blocks and convert them to a single block.

I placed an order yesterday so I can have all the Atari 8-bit carts AtariAge produces. Clearly, AtariAge needs to produce more Atari 8-bit carts!

AtariMax sells carts you can install the new versions of SDX on. (Plus, the 8Mb cart is also good for Space Harrier). https://atarimax.com/flashcart/documentation/

I seem to recall reading that that's exactly the issue - the programmer doesn't check and assumes no one would boot holding down OPTION.

Best Electronics has the cartridge only on sale for $10.00 (https://www.best-electronics-ca.com/addendum.htm)

Yes, but there are ROM files there you should be able to extract and use on atari800. EDIT Bah, never mind. It's a blob, not files.

... or download Altirra and copy over Phaeron's OS and BASIC...

GTIA pin 11 is TRIG 3. That's GINTLK - sounds like it may be a homemade tool to softload ROM images.

I think you can gain a little speed by reducing the number of lookup / ASC calculations: 1000 FOR X=1 TO LEN(URL$):Q=ASC(URL$(X,X)):IF Q>64 AND Q<91 THEN GOSUB 1020 1010 NEXT X:RETURN 1020 URL$(X,X)=CHR$(Q+32):RETURN

The Reunion of Atari Montreal People (TRAMP) renamed itself to Montreal Atari Club Atari de Montreal (MACAM) after the first meeting. Still have a few newsletters to scan, then a bunch of disk newsletters to preserve.

Or try it on an 800 (or 400 upgraded to 48K), booting while pressing FIRE on a joystick plugged into port 3.

So: Using narrow playfield and 16 character lines in ANTIC , you need 256 bytes per display. In 16K you can store 64 different displays, and flip between them by changing a single byte in the LMS. (Plus you'll need 1K for the custom character set).

Look up the ANALOG series on "Atari Zucchini" which will teach all about SIO interfacing and using the joystick ports. You may also want to look at the source code for the 850 interface, which bit bangs parallel ports on 6532 RIOTs for serial and parallel ports.

Patch the OS ROM to include the driver?

You terrible, terrible hacker.

Dave & Sandy Small wrote an interesting article for ANTIC about using an 80 column card in their 800 for development purposes - outputting debug information to the 80 column screen while running the standard Atari display for their program. An early form of multi-monitor. XEP-80 also permits that - and, as an added bonus, has its own power supply so when / if your program crashes in a spectacular manner, the data on the XEP-80 screen will be preserved. (I swapped my XEP80 with Roy Goldman for a registered copy of Daisy Dot III, years ago.)

You don't have to define and fill a string; you could just say RELOCATE=ADR("SKJAHKHGUUIEGIEaIIdEIIerwthaytueivieir") X=USR(RELOCATE,57344,CHSET,4) Of course, this assume that the ML routine has no internal absolute references.

As a 64k cartridge, probably won't run from a file on an Atari without 128k RAM (or more). http://www.atarimania.com/game-atari-400-800-xl-xe-battlezone_560.html

Imagine flipping between a GR 0 and a GR 3 screen every VBI; choose your colors wisely and you could have multiple different background colors for your text. Screen memory, a second DL, and the DLI should all fit in two additional pages of RAM.

XM301s are also plentiful (and still $19.95 NOS at Best). Don't believe all of them have been converted to SDrives yet...

Some of us keep using old versions rather than upgrade because it works for us... though I am planning an upgrade frenzy soon, for my two IDE+, my SIDE, my SIDE 2, my MyIDE+ Flash... and probably a few other devices I have forgotten about.
