I'm not familiar with IBM MAU model 8228 (I have Synoptics token ring hub),
but on the 2513 and 2502 you don't use a standard DB9-RJ45 hood; you need a
"MEDIA FILTER" which looks almost the same (male DB9 but only pins 1,5,6,9),
but has resistors for token ring. You can find MEDIA FILTERS on eBay for
less than $10. Some come with a Cat 5 cable wired in; others have the RJ45
slot for a Cat 5 cable. The Cat 5 cable would be a straight-through.
