Jerome Fine replies: VERY THIN! -); If you have any 5 1/4" FH ESDI drives, that must be about 20 lb. each (well maybe only 10 lb.), then anything less, especially when 2 of any drive can be held in one have is THIN and LIGHT.

Jerome Fine replies: And I have 3 FH 5 1/4" ESDI Hitachi DK515-78 600 MByte drives on the PDP-11/83 that I use. But that is where I draw the line as far as "production" hardware is concerned. I don't regard a 60 lb. RL02 drive as reasonable because of BOTH the size and the weight - aside from the fact that the capacity is only 10 MBytes. On the other hand, I hope to eventually switch from using those ESDI drives to a SCSI drive - an ST32550N drive with a host adapter on both the PDP-11 and the PC so I can move the same SCSI drive between the two systems and run RT-11 or on the PC under Ersatz-11.

Jerome Fine replies: If I am not mistaken, all ST3xxxxN drives have the same physical dimensions. I have some ST32550N drives, so I know what you mean. I can easily hold 2 drives in one hand at a time from the top and up to a dozen drives if I am extremely careful from the bottom. By the way, do you know where I could find a spare ST39171N or similar drive? I see them on eBay every so often, but I have not bothered as yet. Tim Shoppa has bragged about his 9 GBytes SCSI drive that he uses under RT-11 with 256 partitions!!!

Am I missing something here ? I have a SCSI 1 gig Fujitsu model m2266sa hard drive that I've always considered a FH since it's the same dimensions (just over 3.5") as the FH floppy in the original IBM PC. Or does the reference here to 3.5" relate, like 5 1/4, to fdd size . Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com
