[Coladam] Transferring ADAM tape/disk images to physical media

ah yes... you can definitely do it over a serial connection if you have access 
to a serial port on the ADAM. I've used MEX or IMP in TDOS for this... I've only 
ever done it using a DDP as temporary storage for the image before transferring 
to disk, or a hard disk. Someone else might have another approach that works as

No means of accomplishing this over a serial connection?

Disks are relatively easy, provided you have an old MS-DOS or linux PC laying 
around (286-486 machine is perfect) with a double density 5.25" floppy drive. I 
don't recommend using a HD 5.25" drives due to the narrower head width even 
though they will write at DD speeds/track positions since it makes for trickier 
tracking, but it is possible to use those as well. The reason too for using an 
older computer is that newer ones don't have disk controllers in them that 
support Double Density disk formats very well. There is a program floating 
around called 22DISK that is excellent for transferring ADAM CP/M disk formats. 
Otherwise, for regular ADAM disk media you can use the utilities on Marcel de 
Kogel's ADAMem distribution site (the DCOPY and CONVDISK programs). DCOPY is 
what I used to transfer my  collection onto the PC since everything I have now 
is single sided. In Linux you can use the dd command.
