I have a solution to the problem of programming the pub boards if the pub boards do not have the correct updates.
The computer in the pin 2000 obviously has an ISA slot.
I will simply remove the prism card from the pin2k computer board. Connect a normal monitor, keyboard, mouse and hard drive with windows installed on it to the pinball 2000 computer board (with out the prism card it is just a normal computer).
Next we transfer the data to the pub update cards (swep1 & rfm).
Then I remove the keyboard and other devices, put the prism card back in and hey presto we have two pub cards programmed.
No need to buy an old computer that we will only use once.
