I've bootstrapped the machine using the previous DOS 3.3 on the hard 
drive, MODE.COM, and a serial cable so that I can get software on/off 
the hard drive, but not having a functional floppy drive makes me 
nervous.  But there's no rush (it's functional enough) so whenever you 
get around to it is fine.  And thanks!
