Model Master 1000 - Art2part- computer to cnc controller settings for PC

NEED HELP- I am trying to resurrect my Model Master 1000 and use it for purposes of diamond drag engraving.  I have a Dell 4700 32 bit computer - I have the rs232 serial cable that worked in the past.  The computer and the CNC controller or not seeing each other.  I have tried different setting but without success. 

Does anybody have setup manual for Model Master 1000 to share?  Does anyone one have guidance and setup for 2.1 Art2part?

Would someone share there port settings and cnc settings?

I have not found much in my extensive searches on the internet.

Thank you in advance.

Note:  The Dell 4700 with 2.1 Art2Part did not display the specifics just it is not connecting reboot cnc etc.

the Dell 2400 with 2.1 displayed an error and statd the chip in the CNC controller is incompatible with the A2P version2.1 - requires to upgrade cnc chip.

UPDATE:  Found ART2PArt 1.31 Version on floppy discs - swapped out computer to Dell 2400 32 bit -  it is now working!!!!! Yeah

Hope this helps - still if anyone can share the manuals as a resource on this blog it may save someone a lot of headaches.

Carveco Artcam offers is a fair price.
