Ok, got the machine powered up and the welcome file says “welcome to
thermco tmx 10000 system”. From google that looks to be related to furnace

Yeah, both ideas are good ideas. I am considering replacing the rz25, or
adding a ZuluSCSI, that way I could assign one of the devices for

For now, I am just trying to preserve what's

a fresh install once the CDROM arrives. It is an
interesting exercise to
me.
Right now that RZ25 is running nicely without
much noise so no rush I
don't
