It's not likely I could fix all because there are parts missing, and displays for the 8020 variants are a problem even if I could make them all work. I have one 8020 display that works, one that is completely missing, and the rest are unknown but don't look very good.

I know EXACTLY what you are talking about.

Maybe not quite the right colors yet, but I am working on that. I keep getting closer. I drug out all the piano key flukes. Most of the ones that had been so good no longer worked. That was kind of a bummer, but since buttons could be made, and potentially battery doors and stands too, I decided to take it further and try to fix all of them.

I printed a battery door for my 8060A out of white PLA, with an stl file from thingiverse. It works very well indeed.

ogdento made new displays for 8060a a couple of pages back, and also had a thread about an LED replacement design. I read all about that, as well as the project by robertbaruch to remake the LCD for the TRS-80 pocket computer.

Eventually he also had displays made for the Sharp EL-5100 and maybe a couple of others. Dave has a series of EEVBlog videos on the subject as well, although ogdento and robertbaruch's LCD projects are most similar to the Fluke 802x displays. drtaylor had a thread gauging interest in 802x displays, and I think there was more interest in 8050A bench meter displays. It seems like there are so many bad 802x displays out there that someone should do it. I thought it might be me, but it don't believe I have the necessary skills yet to make the drawings, nor do I understand LCD technology in enough detail to write the specifications.

I am aware of the projects by mrmodemhead and others to convert 802x types to a pin-type LCD. That's pretty labor intensive, I wouldn't want to do a bunch of them. If I only need one display, I might do it.

So far I have done one in black PLA. I'd probably do ABS (like the buttons I have been messing around with) or ASA. I've still no found a color that looks like the color on the back of an 806xa Fluke. I don't expect to get it exact, but so far I haven't even come close. I continue to look. That's why I haven't done much with battery doors. I like PLA a lot, but you can't post process it with acetone, nor solvent weld it as far as I know. I would prefer ABS or ASA. My only PLA battery cover attempt so far works but is a bit flawed. I'll try again, but I may attempt to draw my own from scratch at some point.
Dave Wise:
Is there a way to change the frequency of the 8060A's continuity beeper?  It's 2670Hz which is my hearing loss notch.  I can't hear it unless I hold the meter right against my ear, which makes continuity test unusable.
