True or False

[Alastair]

Please correct the following statements as to there validity. Need you experts opinion.

1. On a 82/70 solid state chassis with 5 cards in place when the sweep is at gaurd position TA2 informs the sweep, yep, its clear to run, and the sweep will run across the pindeck. Back at gaurd position TA1 will initiate the sweep to run to home. ??

2. On single conversion boards before 1984 TA1 was used to lift the sweep from 2nd gaurd to home, leaving the table slightly exposed. After 1984 TA2 was used to run the sweep home. (omega-tek single conversion board)

3. Was there a pinspotter that used TA1 to run the sweep home from 2nd gaurd? if so what model?

4. In theory TA1 and TA2 must both be open to let the sweep run from 2nd gaurd to home.

Re: True or False

Not sure about the exact dates, but earlier conversion boards still used TA-1 to run the sweep back to rest from guard (and yes the 5 board chassis did use TA-1 for this)

Re: True or False

With regards to #2, I think the 70s that had the stepper chassis used TA2. I remember when we had 70s, (4 were stepper and 4 were 5 board) that the Omega Tek single conversion picked the sweep later, like the stepper machines did. Anyone care to comment?

Re: True or False

Find it hard to believe that they built the S/S using Ta1 to lift the sweep, exposing the table. Have a few lanes with old omega-tek boards dated 1984. These use TA1 and even with the cams at max adjustment, the table is still exposed as the sweep runs up early.

Interesting to see, toon30, the 70's with steppers used TA2. Why on earth would they revert back to using TA1 in the S/S?? Why?, did they think this would be a good idea? [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

Re: True or False

with 5 boards in my machines the table is left un guarded, fine with the omega tek

Re: True or False

I'm not sure how or why the stepper chassis worked, but they did gaurd the table much better than the 5 board chassis. I did see a table hit once or twice!! My dad has a couple of stepper chassis for the 70s laying around, anyone interested?
