Yes, the mazewar source is saved. I demonstrated it running on my Imlac PDS-1
together with an emulated PDP10 (thanks to Ken Harrenstien) as well as an
emulated
PDS-1 (thanks to Howard Palmer) back in 2006 at a VCF West.

Hi Sellam,
Sorry to hear you are closing up, but understandable. I know you used to
have pieces to an Imlac, but I think you already found a home for them (Mr.
Dersch perhaps?), if not, I would be interested. Further, I am curious if
you have an amber screen Z29 terminal?
Best,
