That sounds like great fun; a PDP-11/44 to PDP-11/44t conversion
project! Does anyone know of any sources for some colorful, and
well-made, switches that would look like they belong on an older
computer's front panel?

For the blinkenlights, my least favorite choice is LEDs; does anyone
have a reason for a preference of Ne2 bulbs over incandescent bulbs or
vice versa? Front panel analog meters for monitoring the PSU voltage
levels would be useful as well.
