Folks, there's something in mythical devices that make hunting them
intriguing. Here we have SCSI to Ethernet, about the same time as the
introduction of the PS/2.

From my non-EE understanding, the Mac system CPU gave priority to disk
access -AND- the SCSI chipset was not as good. I'm no Mac Fanboy, I'm
sure there are deeper reasons for the Nodem performance. One being that
switches were not a thing yet.

If any of you have heretical knowledge of Mac accessories like the SCSI
to Ethernet devices, I won't burn you at the stake... maybe a light
scourging with a Model 95 SCSI cable. I hear suffering is good for the
soul...

Nobody expects the Spanish Inquisition...

Three of the known models:
NODEM - Invented by Adaptec @1988, sold to "LRU Systems" @1993.
Ether+ by Compatible Systems
NuvoLink SC by NuvoTech, but actually made by Compatible Systems.
FastNet SCSI by Dove Computer Corporation.

I have a SCSI to pcmcia adapter..., It only reads memory cards.... You can use a pcmcia universal memory adapter for
various types of card memory though... Very few drivers were ever available for it... Non boot-able as it needed to see the drivers first..
