Thanks for the response. The ELO screen on my machine looks like it is attached with a consistent 1/2" wide, thick material which could be some type of tape. It looks too consistent to be epoxy but I could be wrong. I do know VLC made the slot with both ELO and Micro Touch screens and they obviously had different controller boards to drive each one. I agree just switching out the whole crt assembly would be much easier if I can find one that works and the crt isn't toast.
In my first post I should of said original from factory the touch screens on the VLC were epoxied on along with tape .
so some members dont pick apart what I say and confuse matters .
the easy way to find out if its been replaced over the years with just a tape on model --is to take a electric hair dryer and heat the touch screen slowly equally around the edge and use a old hack saw blade -slim jim idea and see if it pops off easy ----if its tape it will almost lift right off --if epoxied it wont budge .
i think you will find the epoxy is around the entire tube /crt etc . and you wont even be able to get a thin hacksaw blade through to screen side . without taking a chunk of the CRT with it .
as far as controllers yes there is the obvious difference from 3M to ELO --
ELO run on 5 volts dc on that model -
3M Run on 12 volts on that model .
what I was refering to were the "slots computer drivers" being installed for both the 3m & the ELO in the software in machine .
you say they ran both 3m and ELO -
but i would make sure the drivers are there for both ??
if you find the more common 3m touch screen CRT for a replacement which are quite common still .
because you would also have to find the correct software for the 3m if it was only set up from factory for ELO ??
I have two of those old VLC'S converted to POT O GOLDS using brand new CRT'S & 3M touch screens -
I personally like the CRT IMAGE in many video slots vs the LCD -which you have to view at a specific angle to see the image --
the old VLC make great cabinet designs heavy gauge steel and already had the isolation transformer built in - they make great organ donors -plus take many standard glass from many modern day slots along with progressive windowed glass on the top level .
there must be 10 miles of wire in those machines from factory when new . ..
