<h1>PDP-11/45: Teardown and corrosion remediation</h1>
Sat 11 April 2015
by <a class="url fn" href="https://fritzm.github.io/author/fritz-mueller.html">Fritz Mueller</a>
</div>
<div><p>Had a little more time to work on the PDP-11 this weekend. Mostly going after some corrosion on the CPU
cabinet and H742 power supplies. Tore these down, sanded down the corroded bits, then hit with a satin finish
Rustoleum rattle-can which dries to a reasonable approximation of the original powder-coat.</p>
<p>Neon indicators on the H742s are dim and flickery, so ordered some replacements for these, too.</p>
