I read a thread asking about this. I have source code from a real 90s slot. Its for a programmable chip without an operating system like Windows. I understand the code vaguely and each reel icon has a set probability of appearing. It uses a psuedo number generator that does an API call to other hardware. So its not even clear but it might use a combination if psuedo and random noise.
The skinny is I dont think you can even beat a 90s slot with a betting system. You would need another approach. Like casino comps. Think outside the norm. Comps arent exactly a winning method but its one way of getting very good value for money if you live off entertainment.
