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
