Silverball to Star Trek ROMS

[Jack.h]

Hi,

Apologies if this has already been asked, still a bit of a novice with this stuff.

I need to convert a Silverball Mania CPU to fit a 2732 Star Trek and was wondering if anyone had recommendations on where to buy the ROMs and which exactly I would need?

Cheers!

J

https://www.actionpinball.com/tech/35_rom_mod.php for the jumpers, can burn you the EPROM if you have the concatenated file, usually uses three 2716.

 

[Jack.h]

That's great thank you, I don't have the file no, I was hoping to buy readily interchangeable ROMs. https://www.actionpinball.com/parts.php?item=ROMS313 would these work?

And if I were to swap these out and change the jumpers, would that work?

 

[drhex]

Yes, those will work, you can find the jumpers on the link I posted above. Probably is jumpered for 2716 currently so you may want to pay for them.

 

[Jack.h]

That's great thank you! Will it be these ones then that I need to follow?

2732 EPROMs in U2 and U6:

The following is a comprehensive list of settings for all 36 jumpers on the board, when using 2732 EPROM chips in locations U2 and U6: ("nc" = not connected)

1 nc, 2 nc, 3 nc, 4-13A, 5 nc, 6 nc, 7-8, 8-7, 9 nc, 10-11, 11-10, 12-GND, 13 nc, 13A-4, 14 nc, 15 nc, 16 nc, 16A-29, 17 nc, 18 nc, 19 nc, 20 nc, 21 nc, 22 nc, 23 nc, 24 nc, 24A nc, 25 nc, 26 nc, 27 nc, 28 nc, 29-16A, 30 nc, 31-32, 32-31, 33-35, 34 nc, 35-33, 36 nc

 

[drhex]

Yes, that are the jumpers you need.

 

[Jack.h]

Perfect! Thank you so much

 

[Jack.h]

I've just noticed that they don't ship to the UK and you have to use a forwarding service, so could get a bit expensive. Do you know how you go about getting the concatenated file?

 

[drhex]

In theory but have no machine here to check. What is on the board currently? 2716? If so, I can clear them and burn your software.

 

[Jack.h]

Thank you! Pretty sure it's 2716, taken some photos of the board here

If you ask nicely in the right place on Pinside, I'm sure some kind soul will tell you where to get them.....

Once you have the files, there's a number of us here that would be more than happy to run them off for you

Cheers

not 100% sure,but I might have a set of original mask roms somewhere,I put an alltek in mine,as the original mpu had been butchered by someone in the past
