[Coco] Drivewire for Dummies - Part 3 - Chicken and Egg

[Chad H]

I would also be happy to help others with theses services since I can do EPROM programming, have physical drives to make the disks, and pretty gold at making cables..... but first I need to figure out drivewire myself or I'm no good helping others

Now, I saw the pin configuration for the cable, to bad there was no layout chart showing which pin number is which.....I can work on that next...
As for the HDB-DOS, I'm using a custom ROM in my 502 controller now that's based off of HDB-DOS (from emulator ROM's collection I found) maybe it will work?  And you don't have to configure HDB-DOS for serial port?

This includes a loader that basically gets HDB-DOS into RAM, then pulls the rug out from under DECB and replaces it with HDB-DOS.  From then on you are accessing virtual disks through your rs-232 port instead of real disks through your controller cartridge.

However if you do not have drivewire already running, it can be pretty difficult to get the .DSK copied to a real floppy.  There are PC utilities that can do this, assuming you have properly configured floppy drives on your PC (I've never gotten this to work myself.)  Your best bet might be to have someone you know help you out and mail you a disk.  Otherwise, does anyone know if you can still get a HDB-DOS disk from cloud9tech?  That would be a valuable service I think...

Now, you don't have to use an actual tape -- if you have a .WAV file on your PC that contains all the screeching and wailing we all know and love from our younger days, you can get the audio out on your PC connected to the audio in on your coco, then hit play on your .WAV file and "load" it into your coco.  Or, you could play the .WAV onto an actual tape recorder if you wanted to load from a physical cassette.  I feel like someone recently successfully loaded HDB-DOS using a .WAV file, if so, please reply directly to me with your audio file if you are willing--I'd like to test it myself, keep it on hand, and possibly help other drivewire newbies in the future...

How to burn and install ROM images is a subject all its own, and I'm afraid I do not know enough about it.  Again, cloud9tech will help you out, they did me!
