Dear Scott
SRC B1XX4XXX is more likely to do with failure of HW on the mainboard which can be tough for you to handle unless you have access to mainboard parts of this model 810.
May I ask what purpose is it that you want to revive this 810 machine? If it is just to be able to get a basic practice with CL commands in 5250 session, then there is a more convenient way for you as there is a number of web sites providing free basic IBM i access with 5250 session that you can use, for example, at
PUB400.COM.
