IIID which plug directly into the optional I/O slot. They support IBM/MicroSoft
LAN MANAGER and NOVELL Netware network operating systems. There are two
Ethernet physical type supported, either Thin coax or the 10BaseT.
The average data throughput will be about 25 Kbytes/sec which is over twice the
maximum throughput you can obtain on the built in Centronics interface of the
LaserJet III's. (the throughput for the LaserJet II will be about 7 to 8 kbytes
but on all other models you will see the 25 Kbytes).
We also make interfaces for the IIISI and the performance for raster graphics will
be about 6 times greater than the average throughput stated above (product numbers
Hope this helps, product numbers are C2071(A,B,C,D,E or F) depending on network
operating system and physical media (the E and F products are for token ring).
