Why does a hard drive for the ST cost more per Meg than on most other
machines? Because Atari ignored a standard and went their own sweet way.
Let me explain...
Once upon a time, when the home computer world was young, and the ST was
still a sparkle in Sam Tramiel's eye, Atari made an interesting decision.
Virtually every other computer firm had chosen the Small Computer Systems
Interface (SCSI - pronounced 'scuzzy') as the easiest way of linking a
hard drive to their machines, but Atari decided to buck the trend and
design a custom interface. This used a cut-down version of the SCSI
command set, and was christened the Atari Computer Systems Interface
(ACSI). And of course, being Atari, it was incompatible with any SCSI
device.
The legacy of this is that the only way a SCSI device can be connected to
an ST, is via an additional controller that converts the ACSI commands
into something that the SCSI controller can understand. But this extra
circuitry has to be paid for, so when you buy an ST hard drive, you're
being charged for the drive, an additional interface, a non-standard
connector, and then a few extra pounds on top, just for the hell of it.
Third-party suppliers such as Supra and ICD, were quick to design their
own controllers and offered their drives at slightly lower prices than
Atari's, but the only way to reduce the price significantly was to fire up
a soldering iron and build the drive yourself. This was obviously out of
the question for most users.
But there is a way around the problem that hasn't been widely publicised:
all you need is a new or secondhand PC or Macintosh SCSI drive and a SCSI
to DMA port converter. No technical knowledge is required, and if you
can press two plugs into sockets, then you can have a hard drive at the
lowest possible price.
How much you save depends on the price you pay for the drive, but the
cheapest course is to buy a secondhand PC SCSI drive, which will cost you
an average of £1.00 per Meg. An 84 Meg hard drive and an 'ICD The Link'
interface will thus work out at £150 - £160; a saving of approximately
£90 - £100 over the same size, but fully priced ST drive.
The 'ICD The Link' Option
∙°∙°∙°∙°∙°∙°∙°∙°∙°∙°∙°∙°∙
'The Link' is the cheapest and simplest way of connecting a SCSI drive to
your ST. It costs £70 from any of the better Atari shops, and plugs into
the Centronics port of the hard drive, and the DMA port of the ST. It
draws its power from the drive and, once the drive has been set-up and
partitioned, is completely transparent in use. That's all you need to
do; there's no soldering or additional cables required - you simply plug
it in and go!
'The Link' comes in a neat plastic bag with a paperback manual, and a
full set of the ICD formatting and utility programmes. These are widely
held to be the best of their type, and will enable you to partition your
new drive, check it for damaged sectors, and install it to auto-boot.
The A5 sized manual runs to 69 pages and covers the following topics:
1 Introduction
2 A Hard Drive Primer
3 Building an ST Hard Drive System
4 An Internal Mega Drive
5 The ICD Hard Disk Formatter
6 The ICD Hard Disk Utilities Program
7 The ICD Desktop Accessory
8 The ICD Hard Disk Driver
9 Using Your Hard Drive
Appendix A : Utilities
Appendix B : Troubleshooting
Chapter 4 is only relevant if you are using one of ICD's internal hard
drive controllers, such as the AdSCSI ST or AdSCSI Plus ST, and chapter 3
is for techies only. But it's nice to have the information to hand, if
you ever feel the urge to build a drive from scratch.
'The Link' itself is a 24" cable with a DMA port connector at the Atari
end and an overgrown Centronics connector at the drive end. The cable
and connectors are finished in the usual tasteful shade of Atari
Battleship Grey. The packaging states that an additional DMA cable is
required, but you will only need this if you want the drive to be further
away from your ST; the supplied lead is long enough for most set-ups.
Any SCSI device can be connected to an ST with 'The Link' and so, if you
had the software to drive them, you could be the proud owner of the only
ST on your street with a hard drive, Floptical drive, Magneto Optical
Drive, CD-ROM and tape streamer. 'The Link' is compatible with both the
SCSI and the more recent, SCSI 2 standards, and up to 8 devices can be
daisy-chained to the one ST. This means that you could start out with,
say a 65 or 85 Meg hard drive, and then add an extra drive or drives
later on.
Conclusions
∙°∙°∙°∙°∙°∙
And that's it, there's very little else that I can say about the 'The
Link' except that it works, it's reliable, and that once connected it'll
never need looking at again.
My own set-up is a secondhand 85 Meg Seagate drive (thanks Dave!)
connected to a 4 Meg STE via 'The Link', and I can honestly say that I've
had no problems at all with it in six months of intensive use. So what
