a few months ago there was some discussion of roll-your-own hard disk systems,
in particular one approach based on a dma to scsi adaptor built by a company
named berkeley microsystems.  i think jim turner was the first "guinea pig"
in the netnews world, followed up by jawar bammi (sp?).  anyway, with some
encouragement from jim i ventured into the mysterious world of hardware 
hacking (note, i use this phrase loosely, and only to make myself feel like
i accomplished something significant!).  the result was a relatively cheap
and (to date) quite reliable 34 Mbyte hard drive setup.
i just finished writing a magazine article on this experience for "ST 
Applications" magazine.  it attempts to provide the documentation for the 
assembly and installation procedure which berkeley microsystems doesn't.
this article will appear in the march issue, barring any snafus.  i have
arranged permission from the magazine's publisher to distribute electronic
copies of this article to bbs's and usenet.

so here is the deal:  should i post this article, or mail it to those 
requesting it?  the ascii file is about 20 Kb.  i can compress it down using
bsd compress, or i could arc it, or just send it out whole.

for now, if you wish to receive an electronic copy, send me mail to the
address below.  indicate what form you would like to receive it in, and 
whether you think it should be posted to the net.  i will guarantee that
everyone requesting a copy will receive one, the gods of the network
permitting.  alternatively, send me a SASE and i will return you a paper
copy;  this will include two cad graphics figures which i must of necessity
omit from the electronic distribution.
if more than 10 people think it should be posted, and less than 10 people
scream that it shouldn't be posted, i will post it in one form or another.
i know 10 is a small number, but i don't have any good guidelines on how
to do this, so sorry if i offend anyone.

alternatively, you could buy the magazine.  if you don't have ready access
on a local newstand, contact:  ST Applications, PO BOX 980, Forestville,
CA, 95436 USA.  subscriptions are $32.50/yr (12 issues) in usa;  support
disks are also available.  i imagine they would send out single issues if
you're just after my article.  if you write them, please mention my name
and how you heard about this.

if all else fails, send me snail mail or call me.

enjoy!
