The only caching controllers I remember for the EISA bus were made by
BusTek/BusLogic, Promise Technologies, and Tekram, none of which were full
It sounds more like an Adaptec AHA-1740A/1742A/1744 EISA SCSI card. The 174x
is an interesting design, but for actual use today, a 1540CP/1542CP (high
density 50-pin connector) or 1540CF/1542CF (50-pin blue-ribbon connector)
might be a better choice since the performance of the 174x EISA boards was a
little lacking. Other options could be the 1540B/1542B or 1540C/1542C ISA
boards or the later (and better performing) 274x series EISA boards.
The 274x EISA boards were hot performers for their day. My first Linux
box was a 486/50 with 16MB of memory and a 2742 controller. Amazing that
X actually ran on it with (some) root to spare.
I still have a pile of EISA boards in a bin somewhere.
