I have one (and the STG1861).  The Elf 2000 is assembled and works
great.  I'm verifying my disk I/O board (8-bit CF interface plus
Dallas clock chip plus 16450/16550 UART) right now.  I am out of
ancient/recycled 22V10 GALs and am having problems getting set up to
burn modern Atmel ATF22V10s, or I'd have a working STG1861 by now. 
One of my short-term project goals is to get ElfOS up on the Elf2000,
then to get Zork running on it (using Mike Riley's 'zrun3' program I
helped him debug).

If you want a full-featured 1802 machine, I can totally recommend the
Elf2000.  It was easy to assemble and works great.
