[comp.sys.atari.st] Hard disk drives for the ST

jeffers.Wbst@XEROX.COM (Bill) (03/23/88)

With all this complaining about the price of hard drives I'm surprised there
isn't 
more interest in the german magazine article describing how to hack an ibm drive
onto the dma port. I for one am extremely interested in getting a translation
and 
a schematic. If anyone can supply me with enough info to build one at a
reasonable
price please send me mail. If anyone else is interested please send me mail and
maybe we can split the cost of translation.

Why bother with the German magazine ?

1. Assuming that you have the translation, you still have to build a converter
   board.
2. Assuming that you have the DMA->HD converter board you still have to get 
   or write a hard disk device driver/formatter. STHD.prg from Atari and
   TAMInit.prg from GlobeStock are not in the public domain !
3. You can purchase a DMA->SCSI converter with all the software necessary to
   format and access a hard drive for less than $100.00 US.
4. You can by an Atari - 20Mb drive for less than $700.00.

Others have done it, why re-invent the wheel ?

Why not? If you can get a translation it will give you more info about
the ST series than Atari...

This is simple. Tokk less than 2 hours.

Right. You need special software. The "converter" is a little board
providing all signals to connect an OMTI HD-controller
(PC-BUS-controller; Western Digital controllers don't work).
The software listings were included in the article; source and binaries
are availeble on disk, too.

The "converter" costs about 50 Deutsche Marks, less than $30.
>4. You can by an Atari - 20Mb drive for less than $700.00.
An Seagate ST225 plus OMTI sell for <$300 as the Byte shows....

'Cause it is cheap and FUN.
The solution ist not "the best you can get" (not compatible to the
original SH205) but it works
