Most of the MAINDEC hardware diagnostic programs do not depend on exact
timing and can be run successfully on slow Macintoshs or with the simulated
PDP-8/E running as fast as possible. In case of doubt, the MAINDEC passes
with the PDP-8/E and the I/O devices set to run with real time speed running
on a sufficiently fast Macintosh (that is a 140 MHz Power Mac for the PDP-8/E Simulator 1.x version or a Mac with an Intel Core 2 Duo CPU for the 2.0 version).

MAINDEC-8E-D1GB-D PDP-8/E Memory Power On/Off Test (Documentation)
The PDP-8/E Simulator version 1.3 (or later) passes this test
“better” than a hardware PDP-8/E. After turning off the PDP-8/E
with the power key of the KC8-EA Console, the simulator quits. After
restarting the simulator, you only must operate the continue key of the
console, you need not to load restart address 0201 because the simulator
not only preserves the memory content, but the register content, too.
(With older versions of the simulator, you must save the configuration
explicitly because they do not save the current PDP-8/E state in the
preferences file of the simulator automatically.)

MAINDEC-08-DHRKB-G-D RK8-E Disk Drive Control Test (Documentation)
When PDP-8/E Simulator 1.x runs with PDP-8/E real time speed, this MAINDEC sometimes halts with a STATUS REGISTER ERROR at PC:2054 in TST28, the consecutive sector timing test, or at PC:2132 in TST29, the non-consecutive sector timing test. The tests use a 2.5 ms resp. 40 ms delay loop to check if the READ ALL and WRITE ALL commands are able to act on two consecutive sectors and to check if the READ and WRITE commands need a complete disk revolution (that takes 40 ms) to access consecutive sectors. The internal timing of the simulator is not precise enough to always meet this conditions. The faster the Mac is, the more likely these tests pass. PDP-8/E Simulator 2.0 runs this test without any problems.

This is the PC8-E Diagnostics restored by Willem van der Mark, the original DEC version is available on his tests page, too.
To run it, three test tapes
MAINDEC-00-D2G4 are required.
This test only runs with PDP-8/E Simulator 2.0, not with the old 1.x version.
MAINDEC-8E-D8AC-D DK8-E Clocks Diagnostics (Documentation)
For all kinds of real time clocks, this MAINDEC halts at various tests because the timing resolution of the simulator is not precise enough to match the clock frequencies.
