Good to know.
I wonder if there are differences in the joysticks between the cocktail and upright machines.
Usually there is, especially on the older games.
Probably very little difference during same era but I noticed some knobs screwed off leaving raw uncomfortable metal threads for players while other knobs on similar joysticks seemed to be moulded on and the whole stick rod was held in by an e clip circlip on the bottom end … possibly down to supplier prices & availability at time of manufacture?
Always quite short on cocktails but began to get a bit longer on uprights if I recall?
Sorry slightly off ‘universal’ topic maybe?
Also older ones had leaf contacts while as games progressed from l/r 2 way on to gated 4 way and later 8 way then a microswitch contact was more widely used and arm microswitches meant the joystick held two adjacent directions for diagonal action .
The first midway space invaders had leaf buttons for left right … I for one used to get repetitive strain injury in my left hand playing … joysticks on taito SI were more hand friendly … BUT . Only till pacman came out then I used to get a red indentation mark almost blisters on my middle finger , though that game could be played by either hand 😃😃😃
The important fact is cab makers did not make the parts they used as buttons/ sticks/ locks/ monitors / electronics etc they just built them like an assembly line.
So may have had various restrictions on supply … speaking from experience we had these issues to consider on a variety of machines… not least upgrading to better or nicer quality as times demanded.
