Upon the date 01:45 PM 5/7/00 -0700, Bruce Lane said something like: Good catch! This is a really nice crate. Has a 400W switching PSU. Any mass storage in it? Jumpers are the bus grant string. I have a 945 manual buried (and I mean buried!) somewhere up in the library. Hopefully, another listmember can dig his/hers out sooner but if you don't get any info in a week or so, tell me and I'll find a day in which to hunt my 945 manual up. Here's some info from my Moto sales literature collection: This is called an Advanced MAP Controller. (Oh, what was that MAP acronym . . . Manufacturing <mumble> Protocol . . . ??) MAP was a concept used to network computers in a factory, to interlink them within a particular machining cell and to link them with the company production control department, etc. The MAP computers in a manufacturing cell would typically be machine controllers or data collection/crunching boxes. Other uses too IIRC. This 372A is the front-end processor which consists of a 68020 CPU, 68824 token bus controller, 640 k RAM (not much needed here as resources I think were distributed over the network). MAP uses some sort of MODEM which had a very high bitrate (1 MHZ? 10 MHz? Can't recall now) Coaxial cable was the medium over which communications were carried. If you had Moto's UNIX System V/68 R2 running on this box (which I suspect had been) plus other boxen with MAP components, then you could play with it a bit I suppose. I don't recall too much about this protocol nowadays as it was too high falutin for my relatively small company and I didn't investigate in any depth whatsoever. Not sure if it fizzled or was absorbed into any other industrial communication protocol. I just didn't have time back in the mid-80's to study MAP. I think MAP came into use around 1981/82. What is the main CPU module in this crate? A '147 of some flavor? What're the remaining modules? This is an Intelligent Serial Interface. Has six RS232/RS422 serial ports, 9600 baud max, and uses a 68010 processor and 512 k RAM. Four channel DMA on two of the ports, can xfer up to 1 Mbit per sec on on channel. This can be an application specific module in that it has firmware options for 3270 SNA & BSC, 3770 RJE SNA, etc. I think my Moto CODEC modules I got at Dayton a year ago are actually 333-2 modules. BTW, anybody got any Moto CODEC tech info and literature from those days? I'd like to snare one too!!
