i bought a dataflyer 500 for my a500 many moons ago. this card was said to have an optional 25 pin external scsi connector. after buying said drive i could not get this adapter anywhere. does anyone know where to get one or maybe how to make one.

btw is it possible to make this scsi controller work on newer hard drives. the one i have is a 40 meg.

thanks for any help in advance.

I had one at one time, but haven't been able to find it for a long time. All I remember at this point is that it was a flat ribbon cable going to a D-sub 25 connector on a backplate.

The largest drive I ever had on Frankenthousand's Dataflyer was an 800 MB. Altogether, I had about 2 GB (combo IDE/SCSI Dataflyer) plus a 1.5GB Syquest removable. Pity that the Dataflyer died. Maybe it was overworked. ;-)

Yep, that's exactly all that external connector option is. You should be able to find one from any custom cable vendor. Just a 25-pin ribbon to DB-25 (SCSI-1). Plugs into the header labelled "external connector" on the card. I used mine to run an external CD-ROM. (2x reader, even I beleive!)

The Dataflyer 500 was a great controller for its day. But back then, the 105MB drive I had on it was considered insanely large. I have no idea what the upper limit is on that card, though I'd test a lot before using a single disk larger than 2GByte.

any idea what the pinouts are or where i could find them. so i can make sure i got the right one

Any DB25 ribbon connector/backplate will do. Just grab one off an old peecee or mac scsi controller. I think I got mine off a DB25 serial ribbon cable from an old 486 motherboard (before I chucked the lot). I run a 730 mb Quantum Lightning scsi drive off the internal scsi and a 2x Compac cdrom off the external connector. I think there is an upper limit on the Dataflyer for scsi drives, maybe you'd be pushing your luck over 1Gb (I know it definitely doesn't like 2Gb scsi-2 drives (tried an IBM and a Seagate, no dice).

Not sure about this hardware, but you can also extend any normal [i]50-pin[/url] chain to an external connection with completely standard cables/adapters sold by all sorts of vendors everywhere. No difference in performance, so if you don't feel like questioning pinouts (and can manage to route the cable(s) within the case), that's option B.
