I went scrounging again last weekend and came home with this. It looks
like this one from an old Ebay auction.
<http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7530644273>.
It has two HH floppy drives and it is DIGITAL storage so it's somewhat on
topic. Does anyone know anything about these? I've figured out some
controls but I don't have a clue what others do. I'm also trying to figure
out how to use the disk storage and recall function. I inserted a 360k
MS-DOS disk and it displays E7 and it also says ERR if I try to store or
recall anything so I don't think it likes that format and it doesn't seem
to be capable of formatting it's own disks. Does anyone have any idea what
format it's looking for?

Hi Joe
I've thought about getting one of those. They usually
go cheap on ebay.
One possible guess is that they use hard
sectored disk. I doubt they use any specific OS. If you
have a program that has access to the controller chip on
your PC, you might try formatting different sector sizes.
Of course, it might actually use FM or MFM. It might even
be 1.2M. Have you looked at the drives to see what they
are intented for?

No, not yet. I've been having too much fun playing with it. It really
works great! I do intend to open it up and see what kind of drives and
drive controller IC it uses. BTW Grumpy Ol Fred found a message on the net
that said that it used a proprietaty 720k format so I'll try a DSQD disk in
it.
FWIW I also found message on the net that indicatd that the probes for
these need more capacitance compensation than most probes provide so a
"standard" set of probes may not work perfectly on it. Some brands of
probes and some older Tektronix probes do have adaquete adjustment and do
work fine. Right now I'm using a set of probes from one of my other scopes
and I don't want to mess with their adjustment so I'm just putting up with
the distortion. I'll find an extra set of probes and try to adjust them and
dedicate them to this scope.
