Basic Four markets the WYSEpc as a DS-5xx Workstation and the following information describes them. The DS-500 Workstation operates in 2 modes: VDT Emulation Mode using PC HARMONY SOFTWARE to emulate a 7270 VDT or an EVDT. Basic Four applications programs may be run in this mode when the workstation is connected to a Basic Four computer (13xx/16xx series, 2000 series, or MPX family). Stand alone Mode using MS-DOS as the operating System. Many well known programs such as Lotus 1-2-3 will run in this mode. The processing unit chassis contains a CPU board, a power supply, and 2 half- height disk drives (floppies or floppy and hard disk). There are 2 slots for optional adapter cards. The optional adapter boards normally used are the hard disk adapter board, and color/graphics adapter board. Processing unit standard components are: CPU board with: - 256K of RAM memory (8 memory chips soldered in CPU board). - floppy drive adapter circuitry. - monochrome adapter circuitry. - 2 serial ports. - 1 parallel port. Standard backplane with 2 slots. Slots are IBM compatible. Keyboard (similar to IBM AT but not plug to plug compatible).

Detaching the ribbon cables from the fixed disk drive will allow sucessful booting of the diagnostic. When the drive has been properly formatted under DOS the diagnostic will load properly. This problem may be encountered when installing a new system on an unformatted drive. ORIGINATOR: J. Tank CPU-WYSE-WYSEpc-------------------------------------FIB004 Pg001 FIB 00005 08/22/86 *** Use MS-DOS 3.0 or Later to Format 20MB Fixed Disk on DS520 *** Formatting a 20 MB fixed disk drive on a DS520 Workstation requires an MS-DOS level of 3.0 or later. If an earlier release of MS-DOS is used the disk will be formatted incorrectly. ORIGINATOR: D. Wenzel CPU-WYSE-WYSEpc-------------------------------------FIB005 Pg001 FIB 00006 04/27/87 *** Loose Video cable causes video monitor problems *** It is very important to secure the video cable mounted at the rear (mono), or the left rear of the side panel (color), by using the cable plug screws provided. Intermittent cable contact will cause the video logic circuits to burn out. The design of the monitor permits individual adjustment by different operators. During this adjustment, the video cable plug attached at the rear of the monitor will come loose unless tightened with the screws supplied. These screws should be used to keep the plug from falling out of the receptacle rather than to tighten it. ORIGINATOR: P.

Two versions of the Adaptec Hard Disk Controller are supplied under Sorbus MM500050, the board layout is different but both boards are interchangeable. ******** Adaptec Controller 2000A (P/N 400126-00). Jumper blocks are located at location 15A and 4A. For 20 MB disk drive install jumper between M and N at location 15A. For 10 MB disk drive remove jumper between M and N at location 15A. All other jumper positions on both jumper blocks should be open. ********* Adaptec Controller 2000A (P/N 400076-00). Jumpers blocks are located near components RP1 and RP2. For 20 MB drive install jumper between M and N near RP1 For 10 MB drive remove jumper between M and N near RP1 All other jumper positions on both jumper blocks should be open. Note: 20 MB drive is Seagate Model ST225 (MM500110) 10 MB drive is Seagate Model ST212 (MM500100) ORIGINATOR: JAVIER VAN OORDT CPU-WYSE-WYSEpc-------------------------------------FIB008 Pg001 FIB 00009 04/06/88 *** DS-500 20MB Upgrade/Formatting information *** When upgrading to a 20mb drive (Seagate ST225) the Wyse PC FIB #8 specifies the setting of a jumper for selecting either a 10mb or 20mb drive. This should be sufficient if the drive has never been formatted OR has been previously formatted correctly to the specs that are needed by the ADAPTEC controller that MBF uses in the DS-500. If the drive has been formatted incorrectly OR has been formatted with a controller that has a Bios Rom chip setup with different parameters than the ADAPTEC controller, you may have problems getting the format to work correctly...... IE: formatting a 20mb drive and when finished realizing that it only formatted as a 10mb drive...... Although not a common problem, it can be corrected by doing a low level format through 'debug' under MSDOS using the following procedure....... 1- LOAD MSDOS 3.0 OR HIGHER FROM THE FLOPPY DISKETTE 2- LOAD 'debug' FROM THE SECOND MSDOS DISKETTE (2 disks sent with MSDOS) 3- AT THE 'debug' PROMPT - ENTER g=c800:ccc (CR) ----------------ANSWER THE FOLLOWING QUESTIONS----------------------- 4- ENTER INTERLEAVE (1-9) = 3 (CR) 5- ENTER DRIVE ID (0/1) = 0 (CR) 6- USE DEFAULT PARAMETERS (Y/N) = N (CR) -------------ANSWER THE FOLLOWING QUESTIONS IN 'HEX'----------------- 7- STEP PULSE RATE (0/7) = 3 (CR) 8- LANDING ZONE = 267 (CR) (615 dec.) 9- ECC CORRECTION SPAN = 8 (CR) 10- WRITE PRECOMP = 012C (CR) (300 dec.) 11-REDUCE WRITE CURRENT CYL = N/A 12- HEAD COUNT = 4 (CR) 13- CYLINDER COUNT = 264 (CR) (612 dec.) At this point if all is correct a low level format should be completed in approximately 10 minuets. When complete go back to MSDOS and proceed to the normal hard disk setup... IE: HDINIT, SPARE, FDISK, and FORMAT..... The above procedure is for the ADAPTEC controller that MBF uses, other controllers may be significantly different.
