Hey, all, the RK11-D contoller for the PDP-11 uses
Motorola 4015 MSI chips on
one of the boards (M7254), but I can't find out anything about them. Google
didn't turn anything up, and the appendix in the RK11-D Maintenance Manual
that has info about 'all' the MSI chips used in the RK11-D doesn't have this
one. It appears to be a quad flop - anyone have more info? Thanks!
