Currently they're in the position I marked in red. But I've not quite figured out what each jumper does. The 2 upper sections (w/4 items each) of entries in that table are for 15MB drives (used capacity in the 9133, actual drive size could be larger) while the 2 lower sections are for 20MB drives. Although my drive came with a different setting when I got it, I found that an ST-251 drive works fine with the same setting you highlighted (Rev. C, settings EFCD). The ST-251 drive itself can be formatted to hold over 40MB, but when installed as described here, it is only seen as 15MB of storage. Other drives can and do work, but since 15MB is likely more than enough (at least for Series-80 with the flat file structure) I recommend the ST-251 since they are still fairly available, and tend to be quite reliable. Most of all, they're cheap, I got mine for $28. --Bob Prosperi |
