that's why I helped out a couple

Is the 1802 Z-machine code available anywhere? One of these days I'm
going to get one of my Quest Super-ELF machines set up again, and
also build my ELF-2000.
It's a slam-dunk for your Elf-2000. Just slap on the STG disk board
and go get Elf/OS for it...

Once you have things installed, go get this and assemble the source...

I haven't found a V3 Infocom game file yet that wouldn't run with ZRUN3.
If you do find a problem, _please_ let me know. Mike Riley did the
coding, but I set up problem sets and helped interpret the Z-machine
specification for him when there was some ambiguity. I would very much
like to hear about it if there is some condition somewhere that we
didn't cover.
As for your Super-ELF, you'd need to rig it up with 32K of RAM (for ZRUN3,
at least), and port the ElfOS BIOS routines to your particular hardware
configuration, where it differs from the Elf2K. I have a couple of SuperElf
boards myself, bought as-is, that I have yet to complete debugging on
(among other problems I _think_ the 74C922s are damaged on both boards and
I have yet to secure a replacement chip to verify my probings). Once I
get them working, I plan to construct some sort of ElfOS-compatible CF
interface and get ElfOS working on them. Since I already have an Elf2K
and an EmbeddedElf that work, hacking a disk onto the SuperElf is way
down the list of projects, but it _is_ on the list.
Here's a free tip when you get your Elf2K assembled... don't forget to
either stick a battery in the holder for the NVRAM controller chip, or
to remove the NVRAM controller chip and bypass it as described in the
manual. Using the chip with no battery can lead to flakey operation.
