-
- The long awaited file on the PERSTOR 16 bit controller is here at
- last! The information herein is taken from a press release kit
- prepared by Perstor Systems, Inc., and represents known features
- of the ATF controller at this time.
-
-
- The Plain Language Stuff
-
-
- Perstor Systems, Inc. announces the latest additions to the
- PERSTOR 200 series product line. The PS180-16F and the PS200-16F
- are Perstor's Advanced Data Recording Technology hard/floppy disk
- controllers for the IBM AT, 386 computers, and compatibles with
- processor speeds up to 20 mHz. Both controllers feature a 16 bit
- bus and are port address and register set compatible with the IBM
- AT Controller.
-
- The PS180-16F and PS200-16F include dual RAM support and an
- onboard BIOS supporting over 60 different hard disk drive types.
- Each controller supports two hard disk drives and two floppy disk
- drives. Compatible floppy drives include 360K, 720K, 1.2MB, and
- 1.44MB with either 5 1/4 inch or 1 1/2 inch form factors.
-
- The PS180-16F increases the capacity of new or existing ST506/512
- Winchester drives by 90%, whether MFM or RLL. It operates at 9
- megabits per second and allocates 31 sectors per track, The
- PS200-16F increases the capacity of new or existing RLL hard disk
- drives having plated media by a full 100%. It operates at 10
- megabits per second and allocates 34 sectors per track.
-
-
-
- The Technical Stuff
-
- The Perstor 200 Series ATF Controller is a stand-alone single
- board, general purpose Winchester hard disk and floppy disk
- controller. It interfaces up to two hard disk drives and up to
- two floppy diskette drives to a host processor having a 16 bit
- bus connection (an IBM AT or compatible utilizing an 80286 or
- 80386 processor AND utilizing the 16 bit dual connector
- interface). The controller uses the host BIOS which must conform
- to the IBM PC-AT BIOS functionality.
-
- The Winchester interface is based upon the Seagate Technology
- ST506/412HP interface specifications, as amended by Perstor
- Systems, Inc. All necessary receivers and drivers are included on
- the board, allowing direct connection to the disk drive(s).
-
- Separate computer access ports enable communications between the
- host and disk or diskette controller. An 8/16 bit bi-directional
- bus and appropriate control signals comprise these ports. Disk
- read and write data, status information, and command parameters
- are transferred via this bus. An on-board data buffer allows bus
- transfers to be executed independently of the drive's data
- transfer or transfer rate.
-
- The PERSTOR 200 series ATF Controller is based on proprietary
- chips. The RLL encoding scheme is a modified time shifted IBM
- 3360 style format, which has the highest frequency in the all
- zero mode.
-
- The PERSTOR 200 series ATF Controller connects to the system
- board using one of the system expansion slots. The controller
- controls the 5-1/4 or 3-1/2 inch floppy and hard disk drives.
- Connectors on the controller supply all the signals necessary to
- operate up to two hard disks and two floppy disks. The controller
- will allow concurrent data operations on one hard disk and one
- floppy disk.
-
- The controller operates when connected to a system board
- expansion slot. This channel is described in the "System Board"
- section of the IBm Personal Computer AT Technical Reference
- Manual, or its equivalent from another manufacturer.
-
- The fixed disk function features 512-byte sectors, high-speed PIO
- data transfers, ECC correction of up to 22 bits on data fields,
- multiple sector operations across track and cylinder boundaries,
- and on-board diagnostic tests. The controller will support two
- fixed disks with up to 16 read/write heads and 2048 cylinders,
- providing that the host machine BIOS will support such
- capacities.

- allowing control of up to FOUR hard drives.
-
- * The 8-bit and 16-bit controllers can co-exist
-

- transfer rate of 9mbits per second. The PS200-16F will be the
- equivalent of the PS200, with 34 sectors per track, and a
- transfer rate of 10mbits per second.

- $$ Pricing $$
-
-
- Due to anticipated demand upon initial availability of the
- controller, I do not plan to offer quantity discounts and most of
- the sales will be quantity ONE only. Quantity purchases
- will be considered and implemented when the controllers are no
- longer on allocation.
-
- Perstor PS180-16F Controller - Quantity 1 Price - $285.00
- Perstor PS200-16F Controller - Quantity 1 Price - $NA at this time.
-
- I am currently taking orders on the controller and a firm
- commitment in the form of a check in the amount of $50 will place
- you on our list of definite orders. The list of those interested
- in the controller will receive a notice of availability via this
- board or through our planned mailing. Your check will be held
- until the controller is available and the rest of your balance is
- received. Both will then be deposited upon shipment.
-
-
- Please be sure you understand that this is pricing from Sparta
- PCBoard, Richard Driggers (Sysop) dba Arnell Computers. Other
- than trying to offer the best support in the country for a really
- fine product, I have no other relationship with Perstor Systems,
- Inc.
