Supra Hard Drive

Everyone knows about the Atari ST. One of the desirable add on was a hard drive but for most, due to the sheer expense was prohibitive.
Recently in my local free-ads paper I found a guy selling a 20MB hard drive for the Atari, he wasn't asking too much money so I went to buy it. He assured me it worked fine but I must take an Atari and monitor to his place to confirm. That seemed like a lot of bother so I didn't, would you?

Once back home I connected it up and away I went... yes you've guessed it, it was faulty. It took me many formatting, setups and experiments to confirm the actual hard drive was useless. I took the guess the interface and power supply were working.

So I then was on the lookout for a cheap SCSI hard drive. It came via an unusual route, whilst at a car boot sale I happen to start up a conversation with a guy as we both stood at a computer odds and ends stall. It turns out he had two drives for which he would let me have at a reasonable price. So I got them, connected it into the interface and after a few attempts got the thing working. Yes I was amazed too.
It took me a while to realise the Atari can only work with small partitions of about 15MB or so, hence I divided my new 42MB hard drive into 3 partitions.

Then after some time of non-use I ran the Atari to do some work with it, only to discover the power supply had gone faulty. After some decisions, whether buy replacement or repair it myself I decided to opt for the latter. It turned out to be an open circuit resistor, which was a most unusual failure, upon replacement normal operation resumed.

Supra Manual

This describes all you need to know about a Supra drive. I've had to scan the pages in as plain jpg photos so you will need them all to reconstruct the full manual. Also here is a copy of the software needed to run the drive. Driver software
