Known as a 9-57-VCR. IIRC a 9-90-03 piggy backed on a
blank 9-57 board. They did work good, we put in abt a dozen of them in the lates 70's. I have been watching for one to reverse engineer it but no luck in 2 yrs. If anyone has one please give the details. The pin-out should be no problem but I dont know if any changes were made to the board itself or if the 9-90-03 was even used in a TV. This board probably has a hoz hold pot on the board unlike the common 9-90 & an eight pinned IC IIRC. Been to long........... 73 Zeno |

I was thinking about the horiz board, used in the "H" models. I really don't remember the "G" series chassis having that board. |

The delta sets used plain 9-90 there was a 9-90 01 that
may have been for late deltas. The EFL sets & 13GC10 used the pot on board prob the -02 & -03. Someone has the CRSP for modules that will answer the question. 35 yrs ago I could have rattled all this off along with the list prices. A mind is a terrible thing to loose..... 73 Zeno |
