| 149675 | 2003-06-04 06:53:00 | Why are those 3 1/2 floppy disks called 'floppy'? because they aren't exactly 'floppy' . . . . ? Was the name passed on from those old floppy disks? - anyone know what i'm talking abt? those disks were really thin and about 15cm by 15cm . . . . |

| 149676 | 2003-06-04 06:57:00 | Yes - from the 5 1/4" floppy disks... Can I ask why you want to know? |

| 149677 | 2003-06-04 06:59:00 | Oh I was just curious :) had been pondering over this... | caffy (2665) | ||
| 149678 | 2003-06-04 07:03:00 | Because the disk itself is floppy. Slide back the cover and have a look. Where as a harddisk uses aluminium disks. |

| 149679 | 2003-06-04 07:05:00 | If you rip one to bits you'll find that the disk is indeed floppy, unlike the platter in your "hard" drive, which is hard (I don't suggest you rip this apart to prove this, but its an interesting exercise if youve got an old one lying about. | andy (473) | ||
| 149680 | 2003-06-04 09:23:00 | They took over from the 5 1/4 inch disks (originally 360k, later 1.2M) which were standard on PCs until around 1988. Those had themselves taken over from 8 inch beasts (also floppy), which in turn replaced big single (hard) platter removable plastic cartridges from the seventies which from my distant memory housed a 10 inch disk with an enormous 250 kB of storage. | stevee (1780) | ||

(Dos 1.1) 180k single sided and 360k double sided floppys were introduced with DOS 2. But who needed 360k anyway, that was massive storage then. |

| 149682 | 2003-06-04 11:23:00 | Hi GF, Mind you I did use Digital (DEC) RX01 and RX02 floppy disk based Qbus and Unibus systems, these floppies were 8inch single/or double-sided. The RX01 was 256k using the IBM 3740 format and the RX02 was 512k using a DEC RX02 proprietary format. Ah the 'old days' eh? Mind you won't go on about the IBM 1401, 360/158 /168, the Burroughs...... Cheers, Babe. |

| 149683 | 2003-06-04 11:43:00 | Can I sell you the ferrite core memory from a Burroughs E-8000? 2 k of 12-bit words I think. Circa 1969 Still have it, and it most likely contains the last thoughts it had. |

| 149684 | 2003-06-04 11:49:00 | GF, Bought a fully functioning PDP-8E with 16K of core memory, ASR-33 teletype with 10cps paper read/punch various cards A/D etc.... Boxes of papertape programs RIM loaders Focal69 etc etc $10. Still plays StarTrek (although you need a fair bit of imagination... ;-) Cheers, Babe. |
