I've had 10 dec # XX2247 front panel tubular keys machined from the original DEC code settings. These are not duplicates of an existing key, but freshly machined based on the actual key requirements, so they are suitable as master originals. They have all been tested in my pdp11/20 and work perfectly. These will fit pdp8 (classic), pdp8/e, 8/I, 8/L, 8/m, and the 8/L expansion box, as well as the pdp11/15, /20, /30, /45, /60 and /70; also fits the VAX 11/750. They will also work in the pdp 11/24 and 11/44, but are not really required; any ACE blank will work with these two machines. Price is $16 USD including postage in North America; I imagine postage to the EU and points east will be slightly more expensive. Available immediately.
