My XROAR starter kit is the quickest way to get started if your OS is MS Windows.

Kriegspiel (D32 only) is a good one for testing. IIRC this game uses all 10 of the USR() routines.

You could relocate the USR address table to $00ea-00ff. These bytes are unused when DOS is not present.

Our first Dragon software project this year is coming along nicely – feeling a bit less rusty and getting used to BASIC again. If anyone has a program for renumbering BASIC on a PC, please let me know. I could code my own but don’t want to reinvent the wheel. Try the attached MS-DOS based GW-BASIC ...

Thanks to briza, I have a PAL (Australian) CoCo 3 What happens when you enter POKE65495,0 on the CoCo3. Does it (a) appear to do nothing because the operating system is in RAM (like a D64 in' 64 Mode') or (b) Switch to double speed mode as if you had entered POKE65497,0 (like the VCC emulator)? Wha...

That's quite an impressive, and interesting (esp the EEPROM programmer) list. All of the Dragons I listed above are also fully functional.

In my collection I currently have 19 Dragon 32's, 4 Dragon 64's, and 1 DragonDOS + original floppy drives. (1) What hardware do you have in your collection? (2) Anyone got a Tandy CoCo 1, 2, or 3? (3) Has anyone out there upgraded a Dragon 32 to 64K, and/or upgraded the BASIC ROM? (4) How many peopl...

OK, Sent you a mail some time ago, but didn't get a reply. Must be a problem somewhere?

EDIT: removed

Is this correct?

Here are the same four routines with extra code added to make them DOS compatible. These are safe to use on a CoCo or Dragon, with or without DOS. 10 PMODE 3,1:SCREEN 1,0 20 S=PEEK(186)*256+PEEK(187) 30 E=PEEK(183)*256+PEEK(184)-1 40 X=RND(-TIMER) 50 PCLS 60 X=RND(255):IF X=PEEK(S) THEN 60 70 FOR I=...
