name that DEC control panel!

anyone know what machine this panel comes from? The seller claims it's a PDP-11 but I don't see enough bits. Possibly a PDP-8 or educational unit? I've never seen the lights along the side - on an '11.. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2070195230 regards, Heinz

Sender: owner-info-pdp11(a)village.org "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 1.2 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. Zane -- | Zane H.
