I have gone around the country to confirm where the last PERTIS machines are located. I believe that there are 37 machines across the whole country now and I have been to all of them. This is through what people have said recently and Google Maps where possible. These are the remaining ones as listed by TOC managing the station:

My general thoughts were that I was surprised GWR and GA still had some PERTIS machines, though they have not worked in a very long time. Chiltern are actively removing theirs, as the Sudbury and Ruislip (among others) machines were removed this year. Despite working at the start of this month, Debden Golf Club is likely next gone, with the others probably soon going. I doubt any of the machines are going to get fixed, apart from maybe those on SWR, since all but Millbrook are listed in station facilities. All the other machines are probably long gone.
As for the machines that were not Dead (no power to the machine), Out of Use or Out of Service:
- Hatton is currently the best machine to go to for a Permit to Travel ticket. Though since it is on Chiltern this may go soon, and there is no knowing when this one will break.
- Redbridge works, kind of. A ticket is printed, but the date and station is at a 90 degree angle to the Permit to Travel ticket. Also, the date when I got it reads "13 Jan 98", so I doubt you can actually use this to legitimately travel.
- Haydons Road and Wimbledon Chase look fine (Time and Amount are displayed, even if the time is 1 hour off, probably due to it being on GMT), but something is jammed in the Coin Slot.
- Faygate has No Amount displayed. The time does appear but you are not going to get a Permit to Travel ticket out of it.
- Salfords is always on "Pay At Ticket Office" even when the Ticket Office is closed. Probably never going to be turned on to print out Permit to Travel tickets anymore.
Here is the map of all of the remaining PERTIS machines:
