Mike wrote... ------ Cromemco: XX4306 ------ Thanks for chiming in Mike, could use all the datapoints we can get. Can you elucidate which models of cromemco XX4306 works on? I'm not familiar with those machines other than I know there was a 2 and a 3... something about Z comes to mind... And on a specific model, are you able to try/confirm XX4306 on multiple machines? Also - before we get too wide on the systems tracked... the "standard" ace key had a barrel outer diameter of 0.375" and 7 positions. I am aware of 2 other variants that had different barrel OD's and different number of positions. So mike - what's the OD of your key, and is it 7 positions (concave semi-circles around the key)? Some mfg's could have used a different key in each individual machine/lock. Others could have used the same key for all machines, or the same key for all machines of a specific model. It is also certainly possible that some mfg's used two or three different ones over the life of a model/series. So, the more datapoints the better. I'm pretty sure that *ALL* 2100's use the XX2946. I probably have over time had at least 8 2100s, and currently have 4 or 5, and the same key works on all of them. These all came from widely dispersed geographies. I have "more than a few" DG Nova's, and the same key works in every one of them, and they came from varied sources. I only have two Eclipses though, so small sample size there. J

I have one of those dang round keys on my Nicolt 1080. I just took the lock out to a real lock smith and he made two keys for it in a day for $25. I regret to say his shop has moved or he quite the business. I took another lock to another shop an they said they didn't have anyone that could make a key for it. I guess they were just the key copy and tumbler replacement type lock smith.

Micrometer measurement is step 1. Step 2 is verification, meaning give the resulting code to a locksmith and have them make a key from codes only, not a copy. Once you verify that key works in your machine, we can be sure it's right (it's easy to make a 0.016" mistake ;) Positions are 7 to 1 (holding key as if to use, 7 is top left and goes counter-clockwise). Codes are 1 through 8 starting at 0.016 (1) through 0.128 (8) in 0.016 increments. So 4 is 0.064, etc. Old thread - I know that there was lots of talk about the DEC PDP XX2247 key. I don't think I've ever seen/heard any discussion of memorializing others (non-dec).... and we should :) J

We're doing something a little more expansive than that. Fred did a great job of providing detailed fields which the web developer has looked at. If anyone has additional fields, let me know. J
