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>Regards Tony<br><br>January 31, 2022 1:08 PM, <a target="_blank" tabindex="-1" href="mailto:music@artxtek.com">music@artxtek.com</a> wrote:<br> <blockquote><div><div><div style="font-family: arial, sans-serif;font-size: 13px"><br>Hi All<br><br>I recently acquired a Kurzweil K2000 from a local charity shop.<br>It is in excellent condition, back-light is still bright and functional, however it only has OS version 1.0 Calvin so I decided to try and upgrade it.<br><br>I found the site DBWBP.com and downloaded the v3.87C Engine images and the Setup images which I have burned to EPROMS, but when I put them in the K2000, it boots but cannot find the Setup ROMs. I checked the jumper settings and I have a Rev A Engine board that only has JP1 no JP7.<br><br>Much searching the internet located a Service document that stated that the PSEUDO and GODOT GAL chips also need an upgrade to PSEUDO v4 and GODOT v5, currently I have PSEUDO v2 and GODOT v3.<br>The DBWBP.com site has images from a K2000R for PSEUDO v5 and GODOT v5.<br>Can anyone advise if these will work or where I can find images for PSEUDO v4 and GODOT v5 that will work in a K2000 running OS v3.87?<br><br>Regards Tony</div></div></div></blockquote><br><br><signature></signature></div></body></html>
