 Franke seems to think that there would be some interest in Germany for
 a few units, enough to make me consider burning a board.  I would be
 curious to hear what other list members though about price, features, etc.

  The good news is that Harris still makes the 1802 for

  How authentic should a modern Elf be?  Try to use
1822/2101 RAM or use
 cheaper 6264 SRAM chips? 
Very hard to get 1822/2101s, I expect.  A compromise might be to use 2114
or similar.  All the worst feartures of both - not original and not very
 tolerant of power rail inadequacies :-)

  Add space for an optional 1861 video chip,
 a-la the fourth part of the orginal Elf article?  Add space for a 1854
 UART?  Add an I/O port? 
A UART is always good on any machine...

...
  Classic clones, anyone? 
I'd be interested.
