I didn't take my unix pc apart recently but (from memory) it uses a Western Digital 1010 controller chip. Sorry, I don't know what it wants wrt step rates and so forth, but you can format and use quite a variety of hard disks. Which answers the second question - we have dozens (if not hundreds) of people using externally mounted hard disks. I have a 40MB Maxtor, there are other people using Atasi, Miniscribe, Seagate and so forth. Someone posted an article saying they had an 80MB Miniscribe (?) working. Good Luck. Remember you can only put one hard disk on a unix pc (groan). -- Jonathan Clark [NAC,attmail]!mtune!jhc My walk has become rather more silly lately.

Given that you have 2 identical disks (or any power of two) and are willing to cob it up a bit, you can drive a flip-flop or decoder chip off the low order head select bit(s), and convince the controller that you have twice as many heads on one disk. Since all manner of strange disks may be supported, this is still legal. Warning: I am *NOT* a hardware type. I have seen this done on an ST506 interface using two of those $99 5MB disks Priority1 was selling, and I know it's posible. What I saw was not even on a 7300, but the person who did it assures me that "it can be done, and no I won't help you". -- -bill davidsen seismo!rochester!steinmetz!--\ / \ ihnp4! unirot ------------->---> crdos1!davidsen \ / chinet! ---------------------/ (davidsen@ge-crd.ARPA) "Stupidity, like virtue, is its own reward"
