# Enhanced EPROM-Programmer Version 2.5

2708 / 2716 Enhanced EPROM Programmer

## Introduction

This card has been designed to be a functional replacement for the Bits & PCs Nascom EPROM Programmer.  It is fully compatible with the existing software.

The card is a completely new implementation of the design with a number of improvements over the original:

* Single power source requirement (+5V only)

* Completely new track layout

* All components are readily available from commercial component suppliers (..and eBay!)

* Single power switch,  EPROM selection via standard 12 PIN DIL socket mounted switch

* LED power indicator

* Power test points

* Adjustable 25V feed for 2708's
