[sdiy] Unknown IC LB1501 (Roland system 100 sequencer)

[Florian Anwander]

Hi Karl

> Hi gang, anyone knows what a LB1501 IC is or have the pinout handy? I've got a busted Roland System 100 Sequencer 104 on my hands with very weird behavior and i'm suspecting one of these (which seem to be some kind of electronic switch).
The LB1501 and LB1515 were produced by Sanyo and (as far as I remember) 
were used mostly in TV sets (program selectors).

Around a year ago someone posted, that he had found a batch of them in 
New Zealand. I think it was David Balog, but I am not sure...
