  • MP Chasis or Solid state chasis?

    Can anyone tell me te difference between e MP Chasis and a solid stae chasis of a 82-70 ?Is it possible that we change from MP tot Solid State ?

    Thanks

    Solid State chasis is the older type of chasis. This chasis is has 5 or 6 boards, and a different type of C2a,C1 and Masking plug. If you have MP chasis now, I would stay with MP chasis.

        Yes, definatly stick with the MP chassis if you already have it!! The c1 & C2A connectors are the same for both, though. The masking socket on most S/S chassis are a green "elco" plug, the MP's have a round "C23" plug.

          MP Chassis is newer. Less problems with MPs than with Solid State units.

              King, not doubting your years of experience on 70s, but doesn't one have to "cut out" old components that are bypassed when they start causing problems when adding a wanna-be MP board?
              Granted MPs have their fair share of quirks or defects, but the technology utilized is alot more reliable than the 1960s stuff in the SS units.
              I definitely do not question your years of expertise on 70s and Solid State Chassis, but I'd like to hear some of your viewpoints on what makes MPs more problematic than SS units. This reply is not meant to stir up any hornets' nests nor is it to say I know more than you ('cause actually, I think you know more than me on AMFs). I was just always under the impression that MPs are more reliable than their SS counterparts.

              Repectfully submitted,

                  JMO.

                  The house I have serviced on and off for 6 years have MP's.

                  They were installed in 89 with Accu +.

                  At any time, they experience a full host of quirks.

                  List of unexplainable problems:
                  1. When a ball is thrown, either for the 1st ball of the night or later, no sweep or table movement. You have to hit the program zero button or change chassis.
                  2. They had many more problems with the original boards. The LED later style boards ran much less problematic. They have chassis that will not run with some boards. I just do not find the same problems with SS chassis. All my Omega boards will run all chassis.
                  3. In the typical 2 week period between service, I find at least 3 chassis swaps. When put back on the machines, they may or may not run. In 6 years, I have repaired all burnt pins and scokets twice. Burnt sockets do not contribute to their problems. I or my help only had to take a SS chassis off one of my machines 2 or 3 times this whole season.

                  I do not doubt that the MP has improvements over the SS, I just think you have to swap boards too often and take chassis off the machines too often disrupting bowlers. A SS with an Omega Tek with good pins and sockets are bulletproof.

                  As far as knowledge.....I really am not that knowledgeable, just opinionated.

                      Re: MP Chasis or Solid state chasis?

                      Well, I will admit the Omega Teks have very few problems, BUT if the the boards have to be zeroed when they start up, the problem is 99% in the MP board. Common problem is due to the age of the board . The older MP's tend to have (sometimes) quirky problems due to some of the stuff AMF used when they mfgrd. them. I replace all of these components on the boards when I get them in for a repair - many don't. It takes a lot longer to get the board done, but the weak parts of the board are no longer a factor. Things like the original sockets the MP's were made with can cause a lot of weird problems. Omega Tek solders everything to the board - no sockets. Eliminates "so=so" connection problems. I'm afraid chassis swapping is always going to be a problem One quick check on an MP board is to hit the rest button on the chassis &amp; see if the board dies &amp; has to be restarted by the PBZ on the backend. If that is the case - the board has a problem, abeit a somewhat manageable problem (unless you get tired of PBZ'ing the board). Also another quick check is to see if the PBZ will actually switch ball cycles on the mask, 1st-2nd-back to 1st. If it only switches ONCE &amp; then won't - MP board problem.

                      The S/S's biggest problem is the moron that decided to mount the T1 xfmr on its side [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img] That wasn't a good idea at all. Also due to the age of the S/S chassis, you run into other age related problems like elco sockets.

                      All in all , if either is well maintained &amp; problems are noted, either will serve ya well (as long as you put Omega Teks in the S/S!). BUT, the MP chassis has a heckuva lot more room in it &amp; weighs less.... :p

                            This is a good point. Perhaps if you had the MPs under your eyes 24/7 like your SS units, the MPs would run equally as well. Who knows why they swapped them out and how much care was taken when swapping boards. I've seen many places take out 9850 boards and toss them onto the catwalks like wrenches.

                            As far as your problems you listed above, thanks. I was just curious to see what you based your opinion. and, like wbayjf says, the boards are almost always the problem...namely older Mark V and YUCCA boards. The occasional problem of a 24v ice cube relay crapping out or said relay socket becoming loose in its connection (commonly M) adds to frustration alot.

                            But, you can't beat the S &amp; T and cycle buttons on the side of the chassis...very helpful.
