I have just received confirmation from
www.hobbyroms.com that he has burned the patched programs to EPROMS and they are in the mail now - because i'm on the other side of the world will probably take a little while to arrive.
Once they arrive 5 minutes with a soldering iron and I should be all done. will post pics. eventually.
The CPS 1.5 system is actually a very nice peice of work, when they were brand new 13 years ago they must have been amazing.
