QEPIII Eprom Programmer

An Eprom programmer device. Originally by QJump, this was later marketed by Qubbesoft. It attaches to the expansion slot of a QL, with no through port so a multi-slot expander is required if other expansions are to be used, or a single dedicated QL could host the Eprom programmer and networked to another QL system, for example. It has an onboard rom containing its system firmware.

QEPIII provides verification of eproms at 4V, 4.3V, 4.7V, 5V, 5.3V, 5.7V and 6V - under and over voltage verification being essential for reliable eprom service. It also features fats programming at voltages of 12.7V, 21V and 25V. It can program Eproms from 16K to 512K with standard pinouts, or the data and address pins may be re-assigned for ease of PCB layout. The programming software is included in an onboard EPROM, and is menu driven for ease of operation. It is invoked by the command "EPROM". But….it can also be multitasked by "EPROM_M".
