if theres any 720k floppy drives i would like some. i've got a ge workmaster that needs new drives but i am in canada with out a passport or a means of coming to this wearhouse :(

You can mod 1.44 drives and they work...I do lots of it for Amiga Computers.

Tell me which equipment it is connected. I have adapted many kinds of 1.44MB drives to many 720KB hosts, maybe I can give some tips. --- Enviado do meu Motorola PT550 Meu site: http://www.tabalabs.com.br

So the 3.5" version of the format spins at 360 RPM, just like 8" and 5.25" HD. --Chuck

The disk drives are, IIRC, half-height 3.5" 720K drives (not 1/3 or 1/6 height as are most modern 3.5" drives). I've got a couple of old NEC or Mitsubishi half-heights of that era that might work. Both are belt-driven, rather than direct drive. You used to be able to get Teac FD-235Fs in a half-height package; I've got a 235HF that way, but it's been a long time since I've seen another. Did anyone ever sell 3.5" 1/3 height to 3.5" half-height adapters? --Chuck

I can buy them new in Brazil around Us$ 2. I put a pair on my A2000 (anyone has a memory expansion/scsi card spare? :D) and they are working flawlessly :)

My latest favorite is the Samsung SFD-321B. The jumper pads on the PCB are well-labeled and you can get a datasheet for the drive. Both ready and disk change are easily accessible and drive selects 0-3 as well as the In Use output are available as well as 2- and 3-mode operation. They don't seem to be in short supply, either. --Chuck

A caution for USB flash drives, they are VERY static sensitive, and there is no way to write protect most of them. Many govt and high security companies have banned them because on most of them you can't password protect the entire drive, like you could a floppy. Yes, you can still encrypt individual files, but that does not meet their requirements.

The 720K thing hasn't come up yet, as all of the drives that I've sent out have been for PC98-style controllers which don't use 2D media, so I haven't bothered to check.

My boxed Amiga 1200 cost me an old NT4 license and a Compaq server Ethernet card. I had the 8MB SIMM that's in it already. Sadly the expansion board will only take a single-sided SIMM or I'd put 16MB in it. The accelerator board (and PCMCIA SCSI interface, internal 2.5" HD mounting cradle and cable) I had to buy, unfortunately, but the whole thing was about ?30-?40 all in. What I need now is a flicker-fixer board and a copy of OS 3.9. I have contemplated putting a PowerPC accelerator in it and putting MorphOS or AmigaOS 4 on it - but I have MorphOS running on my Mac mini G4 and frankly, with the best will in the world, although it is fast, it is embarrassingly basic and clunky for a 21st century OS. As something from the early-to-mid 1990s, all right, but for nearly 20y later, I'm sorry, but no, it's a bit of a joke. I also have had AROS running on various bits of PC hardware. It is somewhat more impressive, inasmuch as it's 100% free and very fast by x86 standards -- and it was considerably easier to install and get working. As MorphOS is a commercial OS -- nah. Sorry. Not these days. The same goes for RISC OS Ltd's various versions of RISC OS 4 for old Acorn machines, which were ITRO ?80-?100. I'm sorry guys, but it's just not worth it today. RISC OS Open Ltd's free version - yeah, sure, that is interesting and fun. It's like having a fishtank with an /Anomalocaris/ swimming around in it today... http://en.wikipedia.org/wiki/Anomalocaris ... never going to take over again or have any real importance or impact, but a fascinating example of a different path of evolution that died out long ago. The only long-dead weird OS with a modern reincarnation which I think has any real importance or validity today, and which could yet do something, is BeOS and its FOSS version Haiku. It runs rings around Linux as a POSIX-compatible client-side GUI OS. Haiku aside, I suspect AROS, MorphOS, AmigaOS 4, RISC OS, Syllable and SkyOS are probably all on highways to nowhere, sadly. Haiku as well, in all likelihood. :?( -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?
