I've just tried 5-of ex-RS SN74LS365 one after the other in the MK14 in the IC11 (DM80L95) position and it runs absolutely normally even when I have the reset values reduced to my original defaults.

I will also try putting two of these ICs in the IC9 / IC10 positions in the VDU PCB. This will show whether the 74LS365s are suitable replacements for the 80L95s in those positions.
