CoCo Basic interpreter: documented source code

I finally found a very good source of information concerning Color Basic and Extended Color Basic, which already has been of great use to me, patching CoCo-cartridges for the Dragon. Very well documented source code! I think more people might be interested in that: " Color Basic Unravelled II " - Fo...

Re: Katerpillar Attack Cartridge for the Tandy CoCo

Sure, that this is a cartridge? Reading the assembly-code I would think, it's running somewhere between $2500 and $4000 :?:
I would assume it's a disk file?!

Re: BASIC and strings

Well, my approach simply would be to do it the way most of us learnt BASIC back in 198x. We read the manuals of our computers. For example the C64 manual (less than 100 pages) or the Dragon manual :D . The world was not so complicated back then and manuals could be read within minutes to hours. Well...

Re: CoCo cartridge Atom (1983) (26-3149) (Tandy)

Hi tormod, please don't be disappointed. It's just a dumb script (maybe 25 lines) making a dumb list at the moment. I did not print the many JMP/JSR within cartridge space above $C000. The jumps within the program should be ok, shouldn't they? I filtered the jumps from $8000 to $BFFF. And those are ...

CoCo cartridges

Perfect. Can you please mkdir that folder? I made a little perl script, that disassembles all tandy roms with the help of 6809dasm.pl and greps for JMPs and JSRs into BASIC and KERNAL-Rom. The results are listed in a big textfile, which I would like to attach. That should make it easier to see which...

Five Dragon multi cartridges for sale

I am selling five of my Dragon multi cartridges . I do not need all of the ten existing boards for myself. I would like to sell the boards fully equipped and ready, but with not programmed 27C512 eproms, due to the unknown legal situation of the images. It's very easy to program the eproms for anybo...

Re: Toolkit by Premier Microsystems, pics and pdf.

I put Toolkit on the multi-cart. I tried most of the commands. It's working fine. Thanks :)

Re: CoCo cartridge Atom (1983) (26-3149) (Tandy)

Finally working. Not thoroughly tested yet, but playable. Thanks everybody. @admin: How do we proceed? Do you think, Dragon-modified Tandy-roms should be uploaded and stored anywhere (i. e. download/roms/dragon or download/roms/TandytoDragonTest)? There are just a few bytes to change, but there is n...
