Another good point.

Thinking about it, I actually have a few good sources of 5vdc available... a 
powered USB hub (not connected to a computer) seems like it might make a good 
supply, no?

This mailing list has been invaluable, let me tell you.  I've learned so much 
since subscribing, and from browsing through archived posts.  (I've been 
playing around with the CP/M setup in VT, which is very cool.)

Incidentally, I got my DigiKey order today, which is incredible.  I've never 
ordered anything from them before and their packaging is fantastic.  I'm kind 
of amazed that they're able to sell small quantities of components at such low 
costs, individually bagged and custom labeled (even my comments from the 
shopping cart are printed on each bag, which is an unexpected bonus - now I 
don't have to consult a parts list to know which bag is for which project and 
board point!).

Too bad I won't have anything to solder them to for a few weeks yet, and who 
knows how long before the Xilinx programmer arrives from China.  I may have 
working QUADs before I have working REXs.  ;)

To give you an idea of why I'm so amazed to get my DigiKey parcel so quickly, 
here's the estimated delivery times from eBay for the key components to reach 
me here in Canada (and my experience shows that it's most likely to take until 
the end of each time window):

Quad SRAM          Oct 02 - Oct 13
REX Flash          Oct 17 - Nov 27
Xilinx programmer  Oct 17 - Nov 27
