Default Re: 7 segment LED display with different pinout

The first 7-segment LED display MAN-1 ?
Mid-1970's I made a digital clock using 0.3" green MAN-54 I think and they were so dim and expensive. Every year they got brighter and price got lower.
Anyhow, that became a standard pinout for anything like it.

OP, check how you are numbering the pins. Missing pins are usually numbered but not always.
