MicroVAX Diagnostic Monitor
From Computer History Wiki
MicroVAX Diagnostic Monitor (usually given as the acronym, MDM) is a diagnostic software tool for the DEC series of MicroVAX computers, except for the MicroVAX I, which is covered by VAX Diagnostic Supervisor (VDS) diagnostics.
There are two versions of MDM:
- Customer Version
- Field Service Version
The Field Service Version has got some special functions not included in the Customer Version of MDM.
In the beginning MDM was booted from a couple of RX50 floppies.
Later MDM was usually booted from TK50 tape cartridge.
Additionally there was an MDM version bootable over network, called MDMESK (MDM Ethernet Server Kit)
A third version was the "MicroVAX Diagnostic Monitor RA/RD Kit", which is installed locally on the hard drive of the computer to be examined.
