Yeah... For my switchless 11/70 PCB, I'm happy to buy $5 switches, but
if I can't find them that cheaply, I'm not worried about a replacement
method of attachment that might not be as robust as the original
stainless steel punched mounting bar.  The LEDs are nice and useful,
but I'm not going to be debugging software from front panel switches.
They just aren't going to get that much use.

OTOH, I've spent a number of hours debugging a hardware fault with a
PDP-8/L... I've toggled in a wad of 2-3-word test programs as I snoop
and poke at signals.  I'm far less likely to be doing component-level
debugging on an 11/70.
