I too am glad to discover this forum. I just acquired the PC Mill 50 but came with the wrong computer. The previous owner never used it thus not knowing that he received the computer for the PC Turn 50. It appears to be for the lathe version.
Emco Maximat Vertical Mill Drill Head Manual| eBay. Emco PC turn 120; emco turn 120 service manual. I run an Emco PC Mill 50 myself which.
I have a few questions: How do I acquire the Mill version software that will run this machine? Can I use other software to run the machine without any hardware mods and if so, which is prefered. I have a copy of MasterCam 9.1! Can I use that software directly pluged into the RS-232 of my computer and drive the machine. I am new at all this as you can tell. Sorry for all the questions.

Anyone want to send me a copy of the original Emco software for the Mill 50? I appreciat all your help and look forward to getting this machine up and running. You'll need a dongle board which fits inside the back of a windows 98 machine and outputs to rs485 cable, the computer will need to have an 8 bit ISA type slot, and if you want a dongle board.you'll have to approach emco. Theres one in the uk theres also one your side of the pond. And also a private guy that deals alot in emco in the usa whom might help..
Wincam is the software your hunting, it works on windows Xp BUT. The dongle board wont run on a modern machine. So your resricted to a 98 mahcine for running, its no biggy, and a great machine to use if you can find a board. Can you take a picture of the board you have in the PC for the lathe? It may well be the same as the mill board. I have talked to EMCO at some length, and WINcam was targeted at models PC Mill 55 and later and is not compatable with our 50. I have been unable to find the original EMCO software that runs in the windows 95/98 pc so i appreciated your post for sites to go check out.
The schools existing computer is having hard disk problems. If anyone is aware of the information that is exchanged between the PC (and its special ISA EMCO card) and the Mill I would appreciate it, since it does not appear to be sending step and direction info directly to the stepper motors. The winnc32 software you have or the earlier pcnc program from emco is not only for the lathe but can be configurated for bothe the pcmill 50 and the pc turn 50. If you have the winnc program on the computer you can run the winnc-config program installe with it and select a pcmill 50 or a pc turn 50. I hope you do have the original floppy's for the software and the msd-disk (machine data disk) If you install the rs-485 card into another computer you can install and configure the software directly for the pc mill 50.
If you dont have the msd disk you can ask for the data at emco when you supply them with the serial number that can be found near the on/off switch. I Have the same problem as you, i have only an ancient version of winnc with a lot of troubles.
