Actually TMS does still have the EZ console. It has been upgraded to a EZ S which will work with mechanical and electronic along with some other improvements.
It runs on any PC with a serial port. I've used it with a USB adapter and gotten it to work with a bit of hair pulling. If you PM me an email addy I'll send it to you. If you have more than 4 hoses you need to buy the software and get the hardware key. 4 or under and the demo version works unrestricted. If there's a cheaper option out there I haven't seen it. Roughly $1000 for the software if you have to buy it, no special requirements for a PC so any $50 special will do.
