Some Aristocrat Esprit project

[jancsi]

I collect some Aristocrat Esprit.

I want to make backup his eprom content, but one of then has 2708 eproms ,  and for it need -5 V and  +12 V read it.
When I make an adapter  and give -5V and +12V, can I read its content as 2716 eprom (only content will be twice)?

This machines are 220V machines at factory. This machines missing hopper.
I have 110V  Aristocrat Esprit in working order, with big 220/110v step down transformator.
The 220V machine  use same hopper voltage as 110V machine?
Can I tray and play 220V Esprit with hopper from 110V machine?

Digging up an old post here:

Correct. You can make an adapter and read contents as 2716. Like you said contents will be duplicated.
Regarding the hopper from 110 -> 220v i would have to double check.

I managed read all eprom contents. but some slots was not original eprom set.

Some 2716 (on 3. positions) wasn't readable with modern eprom reader (all contets was 0) but old dos eprom reader can read read it perfect.

On 2716 board in 3. eprom positions , I think it  has timing issue, not all 2716  eprom type working  on this position.


Thanks to Opbell I managed rewite one of my eprom set to my slots symbol table and winer table.

One of my slots is  3 reel 4 coin buy type, but eprom set was in it  4 reel and 6 coin multiplier game.

I need find 4 coin buy type eprom sets, or need to do  much more  work rewrite one of 6CM game   eprom contents
to this game.

110V machine used 110V hopper and lamp., 220Vmachine used 220 hopperr and 220V Lamp.
