Dear folks,
Yep, all you need is the proper cabling. I used a "Mac-Designed"
GeoPort (Silver?) for a year or so with my 8088 system. You can
get DB25<->DIN8 cables at most Macintosh dealers (PC dealers
usually don't have 'em). And, just in case you want to build a
DB9<->DIN8 cable, you can use the following diagram, from:

Hope it helps,
