Quoted from frenchmarky:

I must not have payed attention when I tested it before because I was playing a two player game today and the count sounded wrong, then I tested it again to make sure. The EBD 'bonus bug' is still in the code on my Altek-equipped EBD. Previously earned racks on player 2/4 are still scoring 63K instead of the correct 56K (one extra bonus of 7000.)

Strange, I have an EBD with an Altek board (that I installed a LONG time ago) and do not have this bug. Though I definitely did have the bug with my original Bally board.

Quoted from frenchmarky:

Mines only about 2 years old. The first time I tested it and believed the bug was gone, I must have forgotten the specifics of the bug and only tested the first full rack scoring at the end of the same ball with which it was completed (when it does score the rack correctly for 56K), not after subsequent ball drains when that rack it is then scored from storage via the '56K' lamp... and scores wrong as 63K.

Yeah, I'm familiar with the bug...and I most definitely used to have it when I was running the original MPU. But I have not seen it since putting in the Altek (probably about 10 years ago).

Quoted from frenchmarky:

Can you take a look at your Altek board and see what the version # is on the rom chip? Mine is 9.1. Thanks

I will look for the version this evening...I do have free play enabled.

Quoted from frenchmarky:

Plus I'd get back the Oliver DELUXE feature back.

What is the Oliver DELUXE feature?

Here are some pics of my Altek board inside my EBD-LE.

It shows a version for both the ROM and the CPU (?).

This is the ROM that came with it, and it hasn't been messed with since I installed it.

OP
Quoted from slochar:

They are free play roms.

What post are you referring to? What is "they" in this case?

OP
Quoted from slochar:

The freeplay option on alltek is a discrete rom within their combo rom, not some other freeplay scheme. So the "they" is the freeplay rom

Are you saying that they have dual copies of all the machines codes in the same ROM? And that selecting the "freeplay" setting switches between them?
Seems like it would be hard to fit all that in a single 8 meg ROM chip.

If that's the case, then maybe the bug is only fixed in the "free play" half, and not fixed in the "coin play" half.
