No. Historically during the decay of institutions if they aren't too far gone, scape goated minorities have had to play the chameleon for a few extra dollars.

If you get that time machine working, go back to 1964 and tell Ford to use galvanized sheetmetal on the Mustang. Thanks.

How do you teach a gin bottle to fetch?????

You can't teach an old gin bottle new tricks.

I'm seeing a number of EOLs on (for us) rather standard pins and plugs!
 
Digikey just sent me this:
 
Manufacturer MOLEX, LLC
Description CONN 22-30AWG CRIMP TIN
Manufacturer Part Number 0008500114
Digi-Key Part Number WM1114-ND
Customer Reference Number STOCK
Status End Of Life
Last Time Buy Date 06/21/2021
 
You'd think a 50 year old design would just keep going and going...we
use a lot of these in repairing arcade games!

My guess is what is rather a lot for you is probably a few minutes of run for Molex. And tooling up for short runs is no longer economical for a 'just in time' era. Similarly resellers keeping items in stock. Look at your future, and order accordingly. Expect more of this. Manufacturers are learning just how lean they can be, and just how few people they need to survive - and very likely just how sloppy were their operations prior to this crisis. Those jobs are NOT coming back, guys and gals. My guess is that there will be a surge in productivity per worker, but substantially fewer of them.

Nice work!
 
I wasn't really worried about the speed, more changing FFs to 00s seemed
a bit pointless in the grand scheme of things, plus any unused space
(FFs) in the EPROM could still be used if the OP needed something else
in the future.
 
Or just erase and start over...which we've all done I'm sure!

Well, some programmers do optimise by "not-programming" 0xFF, which may
not make much odds on a decent programmer. I added this step to the
custom software for my EPROM programmer which talks over a 4800 baud
RS232 serial link, where every byte matters! :)
 
Same for a "Rapid blank check" (check 1024 bytes spaced through the chip
to check if they come up blank) for quick-sorting of blank vs programmed.

Yes, that's actually a good point -- I've used 27512 parts where I
really needed only a 27128 (with two spare high address lines tied to
jumpers to ground/pullup resistors) to allow four goes at programming
the chip before having to chip-swap or erase!

Too many times :(

After Nov 2020, it was at 74.2 million but then Biden had something for 'em.
