The TC1G has a DX32 control, PC based. It has a CIB (control in a box). The mother board is a half size, all in one, industrial unit. It probably came with a Disk om a Chip. Typically a 8 MB unit. A hard drive was optional. Your mother board may have a ethernet/lan connector on it. I know the later ones do. The problem is you are running DOS and you need drivers for it. I have quite a few mold shops that have installed ISA or PCI lan cards on earlier full size mother boards, loaded WIN3.11 for workgroups and move massive programs that way.
