8048 Homebrew Simulation - Part 3 - Operation There are five articles in this series: Part 1 - 8048 Homebrew Simulation - Introduction Part 2 - 8048 Homebrew Simulation - Java Source Part 3 - 8048 Homebrew Simulation - Operation Part 4 - 8048 Homebrew Simulation - Sample Machine Code Part 5 - 8048 Homebrew Simulation - Simulation After the app loads, toggle RUN to watch the initial program. This app let's you program and verify a 64k memory. To read: RUN and RD off, WR on. Just toggle the address switches to change the address. The LEDs on the lower middle bank of eight will show the data at the address pointed to by the switches. To write: RUN off, RD on, and WR off. Off is down. On is up. You have limited commands, but you can actually load and run a program. For instance, if you reload the app, and reprogram location 1 by flipping A0 up, and set it to a higher number, and then click run, the machine will increment each register and display it starting with the new value instead of 0x00 This article comes from Coprolite: http://coprolite.com/ The URL for this story is: http://coprolite.com/art64.html Copyright 1997-2006 Coprolite.com.
