Do you remember at what point the EPC was capable of doing constant flow?

I can't remember if the first ones only did constant pressure or not.
Both of my 5890 Series II have EPC that can do constant flow and I think they were purchased around 1980. One of them has an additional flow controller so it can do programmed pulses and ramps using either pressure or flow.

It must have been from the beginning then. It was so long ago when we got our first one I couldn't remember.
