Install the Software
The EconoROM III software may come on floppy, CDROM or BOTH. If a floppy was included with your
emulator, it may be a complete install or a patch. Follow the instructions on the floppy.
If the floppy contains a PATCH, you will be instructed to install the software from the CDROM and THEN
apply the patch.
If the floppy contains a full install, the CDROM is not needed and any ER3 software it contains is out-
dated. We still include the CDROM because it contains a wealth of information.
If a floppy disk was NOT included, then the software on the CDROM was the most current at the time the
product was stocked. Follow the directions on the CDROM to install the software. If your system is
configured to auto-launch applications from the CDROM, our launchpad will appear after you insert the
CDROM into your drive. Simply select the ER3 software option from there.
In any event, it is always advisable to check our web pages for any updates. We always post the most
recent versions of our software for free download.
Disable Any In-Circuit Programming Voltages
EPROMs and some FLASH devices are usually programmed with “super voltages” (> 5V) and are designed
to handle such voltages on some pins; EconoROM III is not! If your target is capable of in-circuit
programming, disable or isolate the high voltage, not just the high voltage control signals. Even short surges
during power cycling could be damaging.
EconoROM III is a 3-5volt ONLY device. Any voltage
greater than 5 Volts or less than 0 Volts will damage it.
