SCSI 2.5" Laptop HDD - Connections

[Hodgkinson]

Hi,
I've got a SCSI (SCSI-2?) 2.5" Quantum Go Drive (TM) Laptop HDD from a old Apple laptop, dated 1992, probably 42.9MB in size.

The connector on the end of the drive is similar to that of IDE laptop drives, execpt rather than having the bank of 44 pins, followed by two vertical empty pins and a square of 4 pins that arn't normally used, this drive has a bank of 40 pins, followed by the same two vertical empty pins, then a bank of 4x2 pins.
(No additional power connector either)

Anyone any ideas how to hook somthing like this up to a standard wide 50-pin SCSI + Power?

Thanks,
Hodgkinson.

Btw, the connector-header on the drive is the same pitch, length, and width (Including the extra block of pins) as that on standard IDE laptop drives.

(Doh, I noticed that the other day and forgot to mention, thanks for the post)

On the other hand I was also wondering if anyone had built such an adaptor and got a 2.5" SCSI drive working in their system. Similarly, what might those extra 8 pins be for? SCSI ID? Could these drives be used in the usual fashion on a standard SCSI device chain?

Thanks,
Hodgkinson.

> I guess you`re just looking at a way to use the drive kicking around eh!?  

Yup :-D

Hmmm, despite the drive having "SCSI" printed alongside the connector, it might just be standard 2.5" IDE. A guy on this forums' trying to do more or less the same thing with his (Identical) drive.

What do you folks think?

>I must ask for the small size and requirement of additionally adapter is it really worth it?

Nope. :-D

(Small size = <42.9MB )

In that case I'll keep an eye out for one of those adaptors, but im certainty not going to go and specially buy one. It would be nice if I could get it to be of some use someday, though (One original idea was to have it running alongside my 2.5" drive inside my A1200 for some portable fast* HDD space, should I ever get a Blizzard SCSI...)

(RF Shield and heatsinks on/over the custom chips limits fast HDD expansions to ones built onto accelerator cards…Which tend to be SCSI…)

Thanks,
Hodgkinson.
