Which version of DragonDOS does he use (1.1c, 1.2a, 4.1, etc)?

I have one Dragon32, one Dragon64 and still some deals going on. I have not opened them by now, but the idea was to make a simple board with the two CPUs in parallel and then enable with a switch one of them (/CE), with the computer turned off. The board will sit on the CPU socket. What (for you) i...

I have posted the code needed to enable/disable 6309 native mode in the "Hints and Tips" section. Which machines are you going to upgrade with the 63x09e chips?

Enable 6309 Native Mode: BASIC: 10 FOR I = 512 TO 515:READ A:POKEI,A:NEXT 20 EXEC512 30 DATA 17,61,1,57 Assembly (CCASM): org 16384 start ldmd #1 rts end Disable 6309 Native Mode (6809e emulation mode): BASIC: 10 FOR I = 512 TO 515:READ A:POKEI,A:NEXT 20 EXEC512 30 DATA 17,61,0,57 Assembly (CCASM): ...

Do you have a Dragon with a 63B09E or 63C09E CPU fitted?

I used Encoder09 a lot, but this was some 25 years ago. Today I just don't remember the exact procedure I used to get it into disk. I assume there must be a disk version as well as a cart/cassette version. The archive's copy assembles only to cassette or memory. By the way, do you know if any of th...

Cartridge support was broken from v0.25 to v0.27 . You will need to use v0.24 or the latest v0.28.1 to load cartridge ROM images. Ctrl+I ............ Insert a cartridge. Ctrl+Shift+I ...... Insert a cartridge, no autorun. Ctrl+L ............ Load a file (see below). Loading a file with Ctrl+L autode...

Happy Birthday Dragon 32!

Version 1.1 has been released. List of changes made since v1.0: * Fixed a serious bug which interfered with the operation of RENUM, GET/PUT, and Function Assignment. * Size optimized the Dragon 32 code to leave as much free memory as possible for BASIC. * Speed optimized the Dragon 32 code. * Improv...

I was just looking at the inverse text display hardware mod on page 16 of the March 1988 issue of Dragon User. The mod takes the form of disconnecting pin 32 (INV) from the board and connect to pin 20 (DA11) through a SPDT switch. All very simple, but I would like to know for sure if this is the cor...
