Drip feeding a TNC 2500

Anyone on here able to walk me through a drip feed setup on a tnc 2500 connected too a interact 1 mk2???

Need a good cam post (preferably fusion but something else would work)
Have a usb to serial cable not sure if i will need too modify it or find a computer with a serial something was stated about jumping 2 sets of pins together
Would love too talk about conversational programming as well.
Would be willing too pay someone for some time if that is necessary.

Thanks in advance looking forward too making some chips with this old girl.
