I think we are going nowhere... We do not have to go to a specific point. Let the reader decide where they want to go and let them build their own picture we are spotting from different angles. In case everyone is addicted in black-white coloring, your statement may fit. ;) The 6809 has integer ari...

You're plain wrong here. Integers do not need any shift to be stored in memory, nor for any operations, as the 6809 has opcodes to do the math. What the 6809 doesn't natively have, and what it has to be done by the Basic interpreter, is opcodes to handle floating point numbers. I would judge that h...

I have to disagree here. I don't know what kind of reasoning is behind not having integer arithmetics on basic, but from the processor point if view (6809, not modern ones), everything is integer values. I agree and just to note, the first MS Basic interpreters did'nt have floats at all. Just plain...

Well, it's a damn nuisance not having it (especially with no shifts). :) Imagine to code a CRC checksum algorithm in BASIC (expect using tables) which needs a lot shifting and xor-ing. Just horrible to implement with MS-based Basic dialects (I've done this with CBM Basic just to proof how complicat...

Hallo Johann, and welcome to the archive! This is a very interesting project, and indeed a nice solution as Dragon disk drives were hard to find. I was wondering if the Cbm floppy drive could be used from a Dragon 64, by attaching the drive to the serial port... Thanks for the welcome, I'm wonderin...

Ahhh, now I see the point. As a Commodore user I only would use the "%"-suffix to define an integer variable (like A%=5). I just looked it up in the booklet ("An Introductiuon to Basic..."). Dragon Basic obviously does not have that special data type. I haven't had realized that until now. Strange,...

Several weeks ago we discussed on the Coco mailing list the possibility to use a Commodore VC1541 or similar on a Coco ... That reminds me on my project back into 1987, which I have dug out for the reason to make it accessible to the public ("as is"): http://klasek.at/hc/dragon/iec-floppy/ . Maybe s...
