I've been promising it forever, and I've finally
posted the SVD source code up at www.theSVD.com.
If I'm not mistaken, you could now (theoretically)
create your own SVD from scratch based upon the
And for you SVD users out there that I missed with
my bulk e-mail, the latest version of the software
v2.2 is posted, too. BTW, contact me if you want
to get ahold of the latest firmware v2.3. It has
a couple of fixes for Model 3/4 support as well as
the CoCo. It also has Apple support, though this
requires another piece of hardware, too.
Regarding the source code, there are three different
- GUI - the gui is programmed in TCL/TK so the
tcl source is up there. The SVD CP
distribution is actually a windows/linux
executable that is wrapped up with a
licensed distribution package, so that
isn't included. But the code should run
- Firmware - the v2.3 firmware is posted, and
includes a complete MicroChip PIC
implementation of the SVD. Let me know
if you have problems compiling. I'm the
only one who has compiled it to date.
The firmware implements the "virtual
drive" functionality including generating
the floppy data signals.
- PC Apps - the GUI makes use of 2 PC-based
applications to get the tough work done.
The source for these tools are posted too.
There are some neat things there, including
implementations of file systems for the
TRS-80, Heathkit, and Apple. Again, I'm
the only one who has compiled this code,
so let me know if you have problems.
DISCLAIMER - You use the software posted at www.theSVD.com
at your own risk. Do with it as you will. Change it.
Distribute it. Create derivative works of it. Make
money off of it (yeah right). Whatever. Please, however,
don't b*tch about bugs. By all means report them, though,
and I'll fix them. And PLEASE, don't b*tch about my
programming. I'm just happy/shocked that it all works.
Fortunately, I don't rely on my programming skills these
