[sdiy] SOIC LT101 equivalent / dilemma

[Roman Sowa]

Quite a few of early SOIC chips have different pinout than DIP. It is 
simply rotated by 90 degrees, so SOIC/DIP converters are ridiculously 
easy to route. I guess that was the intention to make them that way, so 
they could be used on existing PCB designs with adapters.
Also my beloved OP249 is like that.
