Congrats!
That error 50 means a bad keyboard VIA 6522. Luckily it's not the COPS. http://lisafaq.sunder.net/lisafaq-hw-rom_error_codes.html
You can buy replacement 6522's from here: http://www.westerndesigncenter.com/wdc/Form_Order_Form.cfm
Hmmm, they only seem to have the 65C22's - not sure if those will work in a Lisa or not, might be worth trying. http://www.westerndesigncenter.com/wdc/w65c22s6tpg-14.cfm
