Glen Stone has not been seen around lately -- rumour has it that he
took a spill on his motorbike recently, so it might be awhile before
he's back on the net. 'Course he might also be reading this almost as
I type...

   In any case, as I understand what he has told me about his planned 
device, it is meant to be a SCSI device just like any other, so you
can daisy-chain with another hard disk, just like normal. (I've not
got a hard-disk myself, but I understand that thisis how multiple HD's
work on Atari.)

   It is meant to be a completley hardware device. Just plug it into your
SCSI port and use as any other harddisk. (It WILL need the same amount
of software as you will have for a SUPRA or other harddisk.)

   This could be a problem... I think Glen is still unsure whether the
ramdisk should be sold as a unit or a kit consisting of some custom
chips and instructions on how to connect them. The kit approach would
surely be cheaper, but few people will be keen on soldering HUNDREDS
of chips by hand.

   It won't be so lousy as a swap device for a sun workstation either,
and I dont think Glen has forgotten that. As for cheap, we'll have to
see how much the custom chips and PC-boards cost...

Disclaimer: I really have nothing to do with Glen's project,
            I just think its a great idea, and have talked 
            about it with him. I really don't KNOW anything!
