ballys 5500 83f error ?

[havasugameman]

just wondering if there is another way to clear this machine without the clear chips? I have replaced the battery and now have 83f error. if not can you point me in the right direction for a set of chips? thanks for the help

If you try to clear it and still get 83F try swapping the two RAM chips and clearing it again.

Most 5500 boards don't need clear chips to clear.

Some older software mains require the chips.

ok but how do you clear it without the clear chip?

I have the same problem. I looked at  the board & can't figure out which are the ram chips. Also not sure how to take out a chip.

Well I posted to you the two pages from the Bally 5500 book that explained how to clear the 5500 with a jumper but apparently someone decided it could not be posted on this site.

Badbaud I would try it again and make sure your attachment is like one of the following file types.

There is no reason it should not be posted on this site.

It's a PDF file. See attached.

ok got it open . but still did not work . still same error never even saw any other codes" ch c or cl c" nothing happened do I need chip set then?

Just to the right of the 4 program chips (the ones with the labels on them) are the two large RAM chips.
 
 Carefully pry each RAM chip out of it's socket using a small flat blade screwdriver.
 
 Slide it between the chip and it's socket (!! not the PC board and the socket !!) and rock the screwdriver back and forth as you slide further down the chip.
 
 Your goal is to ensure that none of the RAM chip legs get bent so they drop back into the socket.
 
 Swap the top and bottom RAM chips, plug them back in (line up the pins with the socket holes and press in gently) , make sure the notch on the chip is still facing away from you (same notch orientation as the program chips) then try clearing the board again.
 
 If that doesn't work you need to see if the RAM chips are getting the voltage from the battery.
 
 If the RAM chip's notch is facing away from you place your voltmeter black lead on the lower left  pin of the RAM chip and the red test lead on the top right pin of the RAM chip.
 
 You should read at least 3.4 VDC, a fresh battery will read (across it's leads) about 3.76 VDC. There is a diode in series with the battery before the voltage gets to the RAM chips and it drops about .3 VDC so don't freak if the battery voltage doesn't read the same as the RAM voltage.
 
 If none of the above works then you need to send the board to our shop. Call Larry at 702-363-9998 M-F 11AM to 5PM PST and make arrangements.

thanks for the info. I will give that a try and report back

[Badbaud]

Keep in mind that some older 5500 software did require clear chips. Don't give up.
