The EMP-20 programmer is an inexpensive, portable, parallel port
programmer that was designed from the ground up to be fast and
versatile. It easily connects to your PC through a standard parallel
port. Since the EMP-20 doesn't use a bus slot, and fits easily into a
briefcase, it is very useful for programming devices in the field, with
a portable computer. The EMP-20 programs a wide variety of devices - See
The EMP-20 programmer device list for more information. Each family
module supports an entire family of devices. Three family modules are
included in the base price of the programmer to support 8/16 bit EPROMS,
87xxx MICROS, and a number of PLDs, with vector testing available. See
The EMP-20 programmer price sheet for more information. Relays and
discrete DAC-controlled analog drivers provide power and ground
The EMP-20 uses the same parallel port I/O scheme as the EMP series
programmers, for an extremely fast communication.

The EMP-20 is extremely portable; since it doesn't occupy a bus card
in your PC, you can pack it up and take it with you anytime you wish. At
only 1.5"x5"x8", with a 2" high power transformer, the EMP-20 fits into
a briefcase or toolbox with ease. The programmer, parallel cable,
Family Modules, together weigh in at less than three pounds!
- The EMP-20 carries a 1 year warranty on all parts and labor, and a
30 day money-back guarantee (restocking fee may apply)
- The EMP-20 is static-protected at the ZIF Socket, Family Module
socket, parallel port, and power connector. The static protection on
the parallel port also protects the parallel port on the EMP-11 from
the 12 volts of a serial port.
- It's case is made of tough .125" thick ABS plastic.

Family Modules are not an entirely new idea. They have been used in
other programmers from time to time, to inexpensively route power and
ground to the device. When you're programming devices fairly slow, then
straight, slide-in connectors are just fine. However, the EMP-20
programs at speeds near the theoretical maximum of some devices, so the
digital signals traveling to the device must be clean, and the power and
ground lines must be solid. Slide-in connectors can experience noise
problems, higher resistance, and corrosion.
To use the EMP-20, you must have the following:
- Operating System: An IBM-Compatible PC, 286 or
above, with 640Kb of RAM
- Hard Drive Space: At least 5Mb of free space
- Interface: A standard parallel port
- Power: 12-16 Volts @ 2.5 Amp, AC or DC
- A standard parallel port cable
- A 48-Pin ZIF socket for DIP parts
- An AC 110V transformer (
a 220V transformer at additional cost is available upon request)
- Numbers 01, 02, and 03
