Basically I looking for two complete Microways "NumberSmasher/EMC" or a couple AllCard memory management units for IBM PC XT computers., complete with drivers and documentation.
..
I can trade first generation Pentium class based computer with PCI slot but without onboard USB.
USB adapters are still available on eBay. Free Bidirectional shipping should be included, in both directions.
..
A small bounty for them might be possible, if a trade is not possible.
..
Thanks'

Old reviews/Ads in:
PC Magazine September 16 of 1986 page 148 and page 150 see the article on the "NumberSmasher/EMC"
AllCard, an add-on memory management unit for XT-class computers PC Mag - Nov 26, 1985 - Page 12
 
I don't know about NumberSmasher but the AllCard is super rare because it was a pain in the ass. Video memory was relocated so most programs needed patches.
 
Ops another "TypeO" in above EMC should be more likely ECM, but anyways
..
Yap, that sounds up the Allcard all right, that is why I preferred the Microway version. But the ALLcard I can still patch it up.
This requires rerouting some of its traces. As far as bugs with early Microway versions that is easily fixable. Mostly due to old driver errors (bugs) and in some of the firmware version for there MMU. Their utility to patch MS-dos/PC-dos based application mostly just adds the code type switching back into the application. (In short makes sure video access is in the DS, ES, Video Bios in CS, segments).
..
For verification their was a Large Ad in Byte Magazine Page 92 (PDF page 86) December of 1986 for the NumberSmasher/ECM.
The other page listed has their other products on it.

The AllCard looks like a nightmare, causing more problems than it solves, at least based on PC Magazine June 10th 1986 pages 176-178:

The board's pacakging heralds it as "a lifetime investment" with "expanded growth potential." This for a board that is not compatible with EGA? A board for which the manufacturer must develop patches for almost every new application you buy?
