- I walked into CompUSA and they had them for $279 w/out controller card
- so I broke down and bought one. I'm using it temporarily with this
- secondary DOS system I have, but the real reason I bought it was for
- Coherent.
-
- I'd like to get the controller card, but before I spend more money,
- does anyone know if the driver MWC is going to write will be for
- floppy controller, harware controller (Colorado's), or the Trakker
- Parallel drive? It'd be cool if they did all three, but that's
- a bit much to expect.
-
- The darn piece of XXXX card I have now is an old Western Digital controller
- card that they actually warn you about in the Colorado manual. As soon
- as I put the tape drive in, I started getting cache memory errors. It's
- an MFM controller and really slow. I gave the cache a wait state, and
- that stopped the errors, but my system slowed down quite a bit. The
- floppy controller in my Coh_Box is an IDE so it should work better. (I
- know floppy is neither MFM or IDE, but the controller type does make
- a difference).
-
- I brought this up because of the discussion about SCSI vs. Floppy
- tape drives a while back. I thought about it, and bought the Floppy
- and here's why:
-
- Even if I switch to SCSI, there will be a floppy controller since
- I only use Intel machines at home, so I can still use the tape drive.
- If I don't, I can still use it no matter what drive I have since I
- will always have a floppy drive whether my controller is IDE, SCSI,
- ESDI, MFM, etc. I can move it from machine to machine easier and
- at lower cost since an IDE controller is like $20. If my SCSI
- controller goes, it's a lot more than $20.
-
- At a work site with Vaxen, 3b1000's, Cray's (what *do* they use?),
- etc. It makes sense to go SCSI since you can cross architectures,
- but it wasn't worth the price to me. I have SCSI on my PS/2 since
- that's the only thing fast enough to take advantage of MCA, but I paid for
- it: $700 for 105meg HD and controller (Microchannel ain't cheap).
- I can still use my Colorado on that, since they sell an external adapter
- kit for it (I have no space left in the box). In fact, if I buy a couple
- of boards, I can use it on all my computers (or I could have coughed up
- twice the amount I spent for the Trakker parallel port backup).
-
- I agree that for a business especially one with multiple vendor
- machines SCSI is best, or if you have both Macs and PC's at home,
- but if all you have are PC's like me, it's not necessarily worth
- the extra money.
-
- BTW, I looked at Irwin drives, but they don't seem to use QIC formats,
- so I stayed away from them. Mountain made some cool ones that used
- IDE controllers (1/2-way compromise between SCSI and Floppy?), but
- I didn't get that since I wasn't sure what writing a driver for
- it would be like, and I only have IDE on my Coh_Box.
-
- My $0.02...can't wait for the driver. This stack of backup floppies
- keeps getting higher.
