Did the BL3 first disk 'fill' the ramdisk when it put on 13K of file 
structure?  How would I zero a ramdisk?

The amount of buffer did not change when I removed the ramdisk (umounted) 
but that can be reused, I think.

I will try using the modules and links first after just umounting 
/usr/X11R6, which might be adequate.

Or maybe something timed out while it was trying to connect?  That even 
happens rather frequently at the highest speeds.  I can't complain as the 
service is free to students.

I have a DOS mail program that worked at 2400 bps from a hard drive but 
not from a floppy disk, because it timed out.  It worked at 9600 bps from 
a floppy disk.  (We had a laptop XT without hard drive).

The question is just academic anyway.  We have external modems.
And if we need to carry along a  keyboard for use with this computer, may 
as well take a modem as well.  2400 bps can be used if you have something 
else to do at the same time.

I will check out links in 8MB soon.
