Hi Don,

Not familiar with the Dell 610, does it have a floppy drive ?

Do you have a machine with a floppy drive and serial port you can use for  
trouble shooting ?

I have installed dual boot on my laptops that allows booting DR DOS or  
W98. Really old WIN but useful occasionally.

If troubleshooting is the issue, just run in a box under whatever WIN is  
installed, up to XP. Don't know what 7 and 8 do, but up to XP it works,  
but has really crappy timing. CW modes don't work properly, maybe other  
things, but it should get you into troubleshooting only one thing at a  
time. If it is slow into transmit or back to receive, this might be normal  
under a WIN dos box. Oh, yeah, almost forgot about this, with WIN. You  
will need to get a file from KA7EXM named UHF3_33X.EXE that deals with  
serial port timing under WIN.

If you have lots of time and a strong will, you might try Dosbox under  
Linux. This works quite well, but would not be my first choice with an  
unknown problem. Maybe you know about Puppy Linux. It will run from a  
bootable CD, and is about the easiest way to get LINUX running.

The CD-R boot sounds like a neat idea. My machines don't support that in  
the BIOS, others do, but not my laptops.

Does your BIOS support booting from USB ? Just an odd thought.

When the DSP-10 is running, does everything appear normal ? screen scrolls  
up screen clock updates, you can change frequency and audio level ?

Was this a TAPR kit ?  (just trying to guess the vintage) KK7P interface  
with ADSP-2185 ? or maybe has a EZKIT lite 2181.

Sorry for having more questions than answers, but I hope this is useful.
