I've had a Mac Plus project on the go for a while now, it's been upgraded to 4 meg or ram, it also came with a CMS 20 meg HD and I've also added an original HD20SC. Most recently I also got a DaynaPort SCSI/Link-T ethernet adapter. The CMS hd works fine with the Plus without a SCSI terminator, but I found that the HD20SC doesn't. But luckily the Dynaport has termination built in so when used with the HD20SC, all works fine. I bought the DynaPort adapter off ebay from a guy in the U.K, it came only with the main unit, no power supply, cable or most importably drivers. But I scrounged around and found a suitable adapter, a 12v 300ma did the trick. I was also able to use the 25 pin male/male SCSI cable off of the CMS hd. And most importanly I found the drivers on the Mac driver museum website. I managed to get it working with the Dynaport 7.5.3 driver package (see link below). Installing the driver took several attempts and it would only install off of a floppy wich had to be named "DynaPORT Installer". I had the DynaPort plugged in and powered on during the driver install and the unit was detected by the install process. Once the drivers are installed there's also a hardware diagnostic program you can run and it will detect the DynaPort. I've now created a 800k image of this disk if anyone is in need of it. Another great resource for getting the Plus on the net was the page on the Jagshouse website (see link below), he has a three part web kit on there wich allows you to install MacPPP and MacTCP, it also has some internet apps like Fetch FTP and Eudora. Once I configured MacTCP with my router settings and plugged everything in, it all worked, I was up and running transferring files with Fetch!
