In the distant past, we had a device called a "Fast Paging Unit" attached to our 4381.
This had many large boards each containing many dozens of small memory chips. It was channel attached and emulated a partial 3380. We allocated it to HPO swapping ala Vista's USB ReadyBoost.

Which ones would those have been? Our 360/50 used punched mylar cards. Any kind of disk that was available at the time would have been physically too large to fit in the frame :-) Regards, Richard Schuh > Why not FBA? > > Oh, seems to me that some of the older high strength CPU's > used FBA devices to hold the microcode. > > Ed Martin > Aultman Health Foundation > 330-588-4723 > ext 40441 This electronic transmission and any documents accompanying this electronic transmission contain confidential information belonging to the sender.
