614.1 | interesting items | BAGELS::BRANNON | Dave Brannon | Mon Jul 27 1987 05:48 | 35 |
| i've never heard of them before, but their catalog is very interesting.
They also sell the components, without cables except for power supply.
C Ltd. SCSI Adapter for the Amiga $249
Adaptec 4070 SCSI/2,7 RLL ST-506 CONTROLLER $169.95
Adaptec 4000 SCSI/MFM ST-506 CONTROLLER $129
CASE & 45 Watt POWER SUPPLY w/Cables $109.95
The Hard Drives are made by Okidata.
Mentions Amiga expansion port pass-thru OPTION, no details
Says supports dual drives with Adaptec and Omti SCSI Controllers
allowing control of up to 14 Hard Drives (7 dual SCSI disks)
They have a few items i haven't seen in a catalog before:
1. dual drive add-on sub-system, must be connected to a complete
system of the SAME size (why?)
$800 for the first 20 Meg, $500 for 20 Meg add-on
2. two replacement PAL chips, says that the stock PALs in the Amiga
generally will not support more than one device attached to the
expansion port. They claim that with these High Speed replacements
installed, four or more devices can generally be attached with
very stable operation.
The chips w/sockets are $22, but the original chips are not
socketed.
Note: they don't sell a slot box, but do sell slap on memory
and hard disks. The discussion on Usenet has the slot
box makers claiming the PALs are ok, saying the reason
the PALs are needed with C Ltd equipment is due to bad
hardware design by C Ltd.

| re.: .0 not true...just called them and the guy there said that
a 22 meg add-on, if you already have an Amiga HD is 499.95; the
10 meg system is 799.95.

| re: .2
the guy you spoke to may have not been aware of the "special" offering.
The normal price list in their catalog doesn't list a 10 Meg drive.
The 10 Meg for $499 offer is on the cover sheet, the text follows:
AMIGA HARD DRIVE SYSTEM COMPLETE - - - - $499.95
This is a complete, ready-to-run, 10 Megabyte SCSI Hard Drive system.
The system includes everything you will need, with easy-to-follow
instructions. Our systems are supplied complete with the C Ltd
SCSI host/controller, an Adaptec SCSI controller, and a fully formatted
10 Megabyte hard drive with metal enclosure and power supply. The
hard drive also has a full ninety day warranty. (quantities may
be limited)
ORDER ITEM # CA-10P - $499.95 SECOND DRIVE OPTION FOR ABOVE: ORDER
ITEM # CA-10S - $329.95

614.4 | OOOPS! | NAC::VISSER | | Tue Jul 28 1987 00:45 | 5 |
| THANKS DAVE. I THINK I'LL GIVE IT A TRY. DOES ANYONE OUT THERE
IN NOTES-LAND THINK I'M BEING TOO HASTY?
REGARDS,

614.5 | Welcome to the hasty peripheral club | Z::TENNY | Dave Tenny | DTN 225-6089 | Tue Jul 28 1987 19:09 | 18 |
| Hasty?
I just ordered a Supra drive from ABEL sight unseen.
Of course, I called the tech line for questions,
and had two reviews here at DEC to go by.
We Amiga owners have never been known for patience.
BTW: I actually got through to ABEL by phone yesterday!
Only after about 15 spaced out calls. I forgot
to ask after the starboard II however, which someone was
curious about. Anyway, I should have the drive by the end
of this week.
Good luck with the 10 meg drive. Is this the same
10 meg drive advertised in this months BYTE? (under
NEW PRODUCTS, I received the magazine yesterday)

re: .5
and speaking of BYTE new products... Aug '87 has
Standard Hard Disks in an Amiga
Amiga 1000 owners can connect up to four standard ST506/412 hard
disk units to their systems by using the Phoenix Hard Disk Controller
from RS Data Systems.
The board uses DMA in conjunction with on-board high-speed sector
buffers to transfer data at the limit of the Amiga expansion bus
(about 25 megabits per second). DMA transfers from the sector buffer
occur in parallel with transfers from the hard disk.
The Phoenix will also support a 2-gigabyte laser disk, as well as
a streaming-tape backup unit. It comes with its own power supply,
cables, auto-configure backplane, expansion enclosure, and driver
software. Designed to Zorro specifications, the Phoenix
auto-configures under version 1.2 of AmigaDOS.
Price: $450; with 20-megabytes hard disk, $995

614.7 | Phone number? | ARKHAM::WHERRY | Servant of Cthulhu | Tue Sep 08 1987 22:08 | 7 |
| Does anybody have a phone number for RS DATA Systems, I would like
to call and find out about this....As I am considering a 30meg Supra
Drive from able, but, if I am able to get this and then buy an
st506 drive, that would probably be cheaper and I might be able
to squeeze a few more MB's plus DMA hey, why not.

614.10 | Scuzzy's better | WHYVAX::KRUGER | | Thu Sep 17 1987 13:41 | 11 |
| SCSI is better.
DMA or not, you will lose out in the end if you don't have a SCSI
drive. The bottleneck is at the drive end, not the expansion port.
If you get SCSI now, you can get a DMA SCSI controller later if
you want. If you get a ST506 drive, you can suffer with an average
of half the access speed (NONE of which matters now because DOS
can't keep up) and eventually ditch the drive. Which is better?
You tell me.

614.11 | | BAGELS::BRANNON | Dave Brannon | Thu Sep 17 1987 18:31 | 12 |
| re: .10
aren't most of the SCSI drives available composed of a SCSI host
adapter, and then a SCSI-to-ST506/412 adapter mounted in the drive
box?
So if you get a ST506 drive now, you could upgrade to SCSI by replacing
the host adapter and the drive adapter, and maybe the cable?
Saves having to buy a new hard disk. And the SCSI pieces might
be cheaper by then.

614.12 | I spell relief: S-C-S-I | NAC::VISSER | | Fri Sep 18 1987 12:21 | 12 |
| I look at it by estimating the amount of hardware that will eventually
be s___-canned; for the ST-506 host adapter first, with a later
upgrade to SCSI, you throw away a host adapter. For an IBM clone,
this might be no great loss. But an Amiga host adapter carries
a large portion of cost of goods in the packaging, including expensive
connectors, that cannot be salvaged. ST-506 drives can be used
today with ST-506 to SCSI/SASI controllers (~ $100), and most
controllers will handle two ST-506 drives; drives with embedded
SCSI controllers will soon arrive at commodity prices and will
certainly supplant the ST-506 altogether.

614.13 | bottleneck | 16BITS::KRUGER | | Fri Sep 18 1987 15:19 | 3 |
| SCSI to ST506 converters will yield performance no better than ST506.
Although you will be able to USE the drive, that doesn't mean it
will be a "good" drive.
|
614.14 | warrants investigation | NAC::VISSER | | Fri Sep 18 1987 15:29 | 7 |
| remember that no interface in the world can speed up the step rate,
rotational speed, or recording density. I believe the drives with
embedded SCSI controllers are at the same state of the art in this
respect as the newer ST-506 units; ST-506 drive with SCSI controller
should be a functional equivalent except for power consumption and
reliability, unless the ST interface itself is slower than the drive's
recording physics.
|
614.15 | SCSI or better to open | 16BITS::KRUGER | | Fri Sep 18 1987 16:05 | 4 |
| SCSI allows parallel activity. ST506 is serial. On a four platter
drive like the ST225 (20Mbyte) I am told SCSI is approximately twice
as fast overall. Of course, the Amiga is not yet fast enough to
notice the difference, but the improved software may change that.
