I stumbled across some quite old Decision Data products.
I tried searching the web for information, but I didn't find anything useful.
As far as I could guess it seemed to be a modular chassis with 10BaseT and FOIRL repeater (hub) modules and possibly bridging modules as well.
Does anyone have any info about the following part numbers:
Decision Data TWM470 Decision Data TWM472 Decision Data TWM473 Decision Data ECM4620 Decision Data ECM4630
Thanks for any info !
