Many EPROM programmers that you see on fleabay are USB based. That
presents a problem to those of us using Micro Channel systems, where
we cannot keep up with the dizzying update path which requires new
equipment and new software... The beauty of the Needham Electronics
EMP series is the device related processing is dome within the
programmer itself. The parallel port based programmer is relatively
immune from the upgrade issues of more modern programmers.
Modern systems can lack any parallel ports, can lack expansion
slots, or the O/S can lack support for the I/O addresses needed by a
real parallel port. Got your supply of PCI or PCIe parallel port
cards? YMMD.

Device in the EMP-11
Yes, the EMP-11 does not use the DOS app, but the socket layout is
still the same... This is a significant bit of information. I
recently fired up my EMP-20, and the buffer was coming up empty, all
ASCII 255... So I looked at the image silk screened on top of the
EMP-20... It shows the square end of the device towards the side of
the EMP-20. There are multiple outlines of the notched end (at each
length, like 20, 22, 24, 26...) towards the top (the end of the
EMP-20 with the parallel port).
Also, always go back to the main menu before inserting or removing a
device...

AC Power Supply
EMP series programmer require either 12V AC or 15V DC.
EMP-10, EMP-11, EMP-21 use a 1 Amp transformer
EMP-20, EMP-30, EMP-31, EMP-300 use a 3 Amp transformer

I have an EMP-11, which I believe uses the same power supply as the
EMP-10. My supply is rated at 12 VAC, 1000 mA. Yes, it says AC, not
DC, which might make finding a replacement a little tricky.
If you can't find one easily, you could try the manufacturer. My
power supply is labeled:
Condor
Model No: A12-1A
Input: 120V 60Hz 18W
Output: 12VAC 1000mA
