<div>My first suspicion is that the GAL chips aren't getting burned correctly. It's hard to find a combination of burner and chip that works in my opinion. On new chips, can you burn the original configuration? At least that gets you a sanity check when burning
PLDs. Beware of true or false checksum tests. Been bitten by that myself.</div>

After searching the internets I finally found the info on how to upgrade a Rev A, B or B2 Engine board that does not have JP7 installed.<br>
I noticed a reference to the upgrade on <a href="https://monotanz.de">monotanz.de</a> - a seller of upgrade ROMs and the site owner sent me a PDF containing the info.<br>
<br>
So the K2000 is running Calvin v 3.87 with just one small issue - it locks up after booting up unless it is in diagnostic mode.<br>
It runs all the diagnostic tests repeatedly with no issue but when I boot into "regular" mode it freezes after a few minutes.<br>
Further study of the upgrade notes indicates that an upgrade of the Pseudo and Godot GAL chips is highly recommended to fix "stability issues".<br>
<br>
I currently have Pseudo v2.0 and Godot V3.0. I found images for the K2000R on <a href="https://DBWBP.com">
DBWBP.com</a> for Pseudo v5.0 and Godot v5.0 however when I try either or both of these chips the K2000 will not boot at all.<br>
<br>
Does anyone have K2000 images for Pseudo v4.0 and Godot v5.0, or am I missing something when I burn the images?<br>
<br>
