That would certainly make sense.
But this is IBM.


I had several, (purchased originally without drives)
I sold the last of them at VCF. The last one that I sold had a expansion
unit that needed "special software", and homemade drive mounts (erector
set parts)

I remember 2 different brands of memory expansion units that required
"special software" to see the memory. And one that did NOT require
"special software" - there was a ROM in it in addition to the RAM.

The original question mentioned it being a "Rapport" unit. Was that the
same company that made the "Impulse" unit?
