Here is what I posted a couple days ago to info-pdp11. BTW, someone else
commented that the actual CPU on the M7341 is a i8008.

"1.1 Introduction
Digital Equipment Corporation's Microprocessor Series (MPS) consists of a
group of four M series modules and an optional operators control panel,
designed to efficiently perform a range of process control and
decision-making functions that were previously uneconomic subjects for
automation. When used together, these modules can from low-cost digital
control systems that exhibit the characteristics normally attributed to
more costly minicomputer-based systems. With this capability, systems
structured from MPS modules can perform the functions of dedicated
controllers, operate as a Central Processor Unit (CPU) in intellegent
terminals, perform data aquisition and analysis tasks in the laboratory,
and automate a host of industrial processes

General Description
The Microprocessor Series is listed below by model number and name:
* M7341 Processor Module
* M7344-YA 1K Read/Write Memory Module
* M7344-YB 2K Read/Write Memory Module
* M7344-YC 4K Read/Write Memory Module
* M7345 Programmable Read-Only Memory Module
* M7346 External Event Detection Module
* KC341 Monitor/Control Panel
In a systems context, the M7341 Processor Module (PM) acts as the central
processor unit with the remaining modules performing supporting functions.
Activity in a given system, then, is directed by a unique stored program
contained in a read/write and/or a programmable read-only memory and
executed by the PM. A major factor in the structuring of an MPS system for
a specific application is the development of this unique system program by
the user. To support user development of application software, Digital
provides the Microprocessor Series Software Tools (MPSST) package that
includes the following routines:
* Microprocessor Langauge Editor (MLE)
* Microprocessor Langauge Assembler (MLA)
* Microprocessor Read-Only Memory Programmer (MRP)
* Microprocessor Host Loader (MHL)
* Microprocessor Debugging Program (MDP)
* Master Tape Duplicator (MTD)
In addition, the Microprocessor Program Loader (MPL) is available to users
of the optional KC341 Monitor Control Panel."
In looking further at the handbook it appears that the MPSST package is run
on a PDP-8/e, /f or /m and is papertape based. The MRP expects a MR873
PROM writer to be used in conjunction with the PDP-8.
Looks like an interesting device, to bad the one on ebay is just the front
panel.
