Well I guess I define "obsolete" as "useless". That seems to jibe

"Better" is debatable...the lack of standardization in the flash
world is one thing that keeps me going back to EPROMs for my
projects. Something doesn't become obsolete just because something
newer is available.
When it's not being designed into new products, wouldn't it be fair
to call it "obsolete"? But my main point is that UV EPROM requires
some specialized tools to erase and program. If I were starting out
from zero, I wouldn't waste my time.
I dunno, man. Flash is often a pain to deal with, mainly due to
the lack of standardization that I mentioned earlier. But to each
his own.
If you don't like flash, there are alternatives.
FRAM, for example,
is of a size that would adapt very nicely to a "vintage" project. I
believe that 5v DIP-based parts are still available. That might also
conveniently bypass the need for an emulator.
I've played with I2C FRAMs, but not byte-wide parts. Are they
easy to program?
Or just get an EEPROM programmer and forget about the
eraser.
Pinouts are reasonably close to UV EPROM in many instances, so if you
wanted to go "authentic", there wouldn't be a problem.
That's true...but then you're squarely in "specialized tools"
territory again.
Please note that I've got a couple of programmers
as well as an
eraser--and a big pile of EPROMs. I use them. But I don't find it
particularly convenient.
Fair enough. :-) I've been dealing with them for a long time (as
you have) and it's just second nature to me; I don't really notice
the inconvenience.
