I remember a while back looking that pinout up on the internet - but its been a long while - it might still be there some where, you should try to do a google search.

i had a sym 1. dont have it any more though - it got broke.

replace the keyboard, it attaches via a ribbon cable. i had the same problem once, that fixed it.

I had an apple III at one time - that was on odd one. - nothing like the lisa - if you would have had a lisa trashed - you would be out alot of money on the resale, those things sell for ALOT.

I go to the flea market and buy apple II's but then, i am into the vintage hardware
