[DSP-10] Computers, what are you using ??

HI, Mike!

I have used a Dell 486/50, a Toshiba Satellite 1605 CDS Laptop with AMD K6-2,  and
newer computers, but settled on using PS2 76/486's as I have been able to get them
for about nothing.  I currently run the DSP-10 on a PS2 76/486 with 16 MB of memory
and everything is happy.

I have used various versions of MS-DOS and true MS-DOS mode with Windows 95 and then
98 and 98SE, but I have settled on Caldera DR DOS v 7.03.  I have been running that
for a couple of years with no problems on the PS/2.

I originally chose Caldera DR DOS because it allowed me to do [limited] multitasking
in a DOS environment, and I find that the operating system has a lot of user-friendly
features lacking in the stock MS-DOS.

I have found this perfectly adequate for running the DSP-10.  

The only negative I have with this system is that I have not connected it to the
network, nor have I interfaced it with one of the GPS units here, and so I must
manually enter the time for the 'special' DSP-10 modes that require accurate timing.

This is an annoyance, but it is my fault I haven't resolved this issue.

I didn't have any computer-related problems with any of the various hardware /
software combinations I tried.  This is in line with the way bob designed the
software, to run with very little CPU load.  The only significant computer troubles I
recall hearing about were those related to people trying to run things in DOS windows
from within Windows, or trying to use old versions of EZFAST.  But I haven't really
paid close attention to all of the problems reported on the reflector.

Anyway, I am running the DSP-10 on essentially "free" computers, and I have
stockpiled enough in my attic so that I think I have a lifetime supply of them.  So I
am OK as long as they keep making the CMOS/clock batteries for them.  If they stop I
guess I'll have to jury rig something as you did, for I also discovered that the
IBM's won't run without a good battery [or substitute].

I apologize if this email is a bit 'poor' in syntax or content, but it is the middle
of the night as I write this.  I am having a lot of fun trying to see [in vain, I am
afraid] the MGS CW test signal with a homebrew setup and Linrad.  No real signal, but
as it gets later I am able to see more and more interesting patterns in the waterfall
noise display.  Hmmmm...  ;)
