I talked with IDT again today and got some more info on the scsi interface for the 7300/3b1.. Release date is first part of july. Intro price is $350 and will include scsi board and drivers. board is warranted for 1 year. Still not a lot of info on what the scsi drivers will support. I did make it know that I along with several local folks are interested in connecting the scsi buss back to a scsi to 506 interface so we can use cheaper 506 disk. IDT is looking (down the road) at having tape backup as well as scsi disk available in package deals. Looks like this will be an easy way to increase your disk space.. scsi board, scsi to 506 interface and a bunch of cheap 506 10/20/40mb disk. Now you have a use for that old 10mb you took out when you got the system.. -- Gary W.

Who is IDT, and how do I get in touch with them? I want to sign up for a
scsi adapter right away!
Thanks.

I can suggest what I think is a *much* better idea: buy a bernoulli box. They were expensive ($1500?) a couple of years ago, but I'll bet they're reasonable by now. They come in 10, 10+10, 20, 20+20, 10+HD, 20+HD, and maybe other configurations as well. They're basically an 8inch floppy that holds 10|20 megabytes, spin about the same speed as a disk, have about the same xfer/access time. I've used them on an AT running QNX (a small msg passing OS that has some unix feel to it) and I've run off of the bernoulli (i.e., root mounted on /dev/bernoulli0). The only problem is that they don't spin the disk all the time, so you suffer a delay if the machine has been idle (disk wise) for 30-120 secs. You can easily get around this by writing a disk daemon that touchs the disk every 30 secs. bdflush will do that for you, now that I think about it. Disks cost about $10 each.... Think about it - you can mount /usr/news on one and backup to the other. Limitless random access disk space.... And if you want to use them like tapes, hey, no problem... If they do come out with a scsi board and specs, I'll buy a bernoulli and write the driver (I have an old SysIII based scsi driver for the bernoulli somewhere). -- Larry McVoy lm@arizona.edu or ...!{uwvax,sun}!arizona.edu!lm
