When I perchased my PTR1 from IRTI about two years ago, I recieved this list of compadible drives from one of the techs. The only thing is, I'm not sure if theese are all up to date. Good luck with finding something that works for you.

For exemple: i want to buy an external drive and i know that the IBM micro drive compatible is. And also i know that i have use this drive with an adapter and that the biggest drive is 6gb. But this is rather expensive. Is there any one of you who can tell me something of the prices and also of the sizes of the drives. Because an big external drive would be very handy. Thanks a lot already. With friendly regards, Bob Bullee
