I wrote a BASIC monitor program back in the eighties which I used a lot for entering machine code and debugging, but I will need to rescue it from some old tapes if anyone is interested. There is also a simple machine code monitor program used as an example in the "Inside the Dragon" book. I copied ...

I think I looked up the document in the original post once. I did not get totally convinced that the author actually had made one himself. There was a lot of detail on trivial things, and no comments on the difficult parts... DIY projects sometimes come up in the CoCo mailing list. See for instance ...

Is HDBDos compatible with DragonDOS? I'd like to use DriveWire with Dragon disk images. No, the Dragon DOS disk format is not supported by HDB-DOS. Until someone adds support for it, you'll have to convert the images. The Toolshed utilities can be used to create disk images and copy files to them, ...

alibaba.com is more for buying larger quantities and bargaining with the sellers. Usually no prices are given up front. (Life of Brian, anyone?) Their sister company aliexpress.com is more like eBay Buy Now, where you can buy one (or a few) units at a given price. I have myself only recently started...

Thanks KenH! I have updated the attachment in the original post with your padded disk image. jedie, I have also seen DN ERROR when accessing the disk too soon after formatting it. Is it better with DriveWire 4? I haven't tried DriveWire 4 myself yet. When I can choose between a 28 KB C program (writ...

Just awesome! Love fractals! I remember firing up the Dragon (a few years after the "wild years") to let it draw a fractale fern. Maybe I still have that program on a cassette somewhere. Anyway it was a short BASIC program, and it tooks hours before there was much of a fern to see.

You're right, calls within the cartridge above $C000 are no problem. Also, most (all?) indirect ROM calls at $A0xx are portable. Note that the disassembler easily gets out of sync with the code when it encounters data fields without knowing, and tries to interpret data as code. I guess this is the r...

Hey Tormod, what about a small cartridge with the DW EPROM on it ? That would the be perfect solution! Damn you. Someone always has my idea before I get around to building them. ;) Well, I have no intention of building ROM cartridges, and hope somesome else can offer this. I see that Rolo offers mu...

For instance I have some WAV's of whole cassettes that I want to extract all the files from (CAS would do). I tried DC.EXE for this (running in DOSEMU) with variable luck, and that program is anyway dead (no source) I believe. Oh, that's too bad! R.I.P. :( I do have the DC source; some of it was us...
