If you take the program card apart you will notice some eproms, there should also be a pic/boot chip, this fault is saying it cant fit the pic/boot chip.
Have you got another mpu5 machine that you could swap the pic/boot chip with, they will need to be the same kinda age too.
Hi Starleisure,
Thank you for your help with this problem, i am presuming that the program card is the part i have taken pictures of and attached on here? please accept my appologies if i seem a bit thick i am fairly familiar with fruit machines but not sure of the correct names for some parts. I have taken what i think is the program card appart (please see attached pic) and can only see 1 eprom please correct me if i am wrong, i presume the eprom is the black chip in the pic with the sticker on saying RTC CATK if this is correct i have checked it is pushed in correctly tried it again and still saying the same message. I have got 2 other MPU5 machines Vamp it up and Austin Powers both being older machines, i have tried the cash attack program card in the vamp it up machine and got the same messages, i have also tried the vamp it up program card in the cash attack and with bottom cash door open it says initialising, spins reels,then continues through to read meters with start button flashing taking you into menu's but with cash door closed it gives message initialising no reels spin then alarm 17-83 pnd opto blocked then tamper which does'nt concern me because the hopper wires have been cut through which if i can get machine running should be an easy fix, thus making me think the game eprom in the pic with sticker on as gone faulty. Please continue to help me with this problem as without you guys i would be stuck and end up scrapping what looks like a great machine. Thx again to all. Kind regards Mick.
