Possible control panel for elf project (or parts)
While I was cleaning up I found an old pendant for programming an old computer system. I have no idea what this was originally for but someone here may want to use it for some custom 1802 based project.
I haven't pulled it apart but it looks like it has 4 of the same hex displays that were used on the ELF. If you need any of them then this may be useful for parts.
