The following is a brief description of the DayStar Digital PC Interface board, which is available from DayStar Digital. For more information about this AppleTalk network card, contact DayStar technical support at (404) 967- 6050.

The system requirements for this product are as follows:

  • MS-DOS version 3.0 or later
  • 256K RAM

The DayStar LocalTalk PC Interface board allows an IBM PC or compatible, IBM PS/2 Model 25, or IBM PS/2 Model 30 computer to connect to the LocalTalk local area network.

The default factory settings for the DayStar LocalTalk PC Interface board are as follows:

   Description          Default     Other Possible Values

   Interrupt            None        None
   DMA Channel          None        None
   Board Address        340H        300H, 330H, 350H

The board address used by the PC Interface card can be changed by moving jumpers (plastic clips) on the JB1 jumper block of the card. For more information on changing the board address, see the DayStar LocalTalk Interface board documentation.

The software device driver DTALK.EXE must be loaded into memory before the PC Interface board is used with the AppleTalk network. This device driver can either be loaded into memory when your computer starts (by modifying the AUTOEXEC.BAT file) or run from the MS-DOS prompt. If you change the default board address of the card, the DTALK software driver must be informed of the change through a switch setting. The syntax of the command used for installing the device driver is as follows


where "xxx" denotes the new address.


DayStar Digital also manufactures the MC Interface board, designed for the Micro Channel Architecture of the IBM PS/2 models 50, 60, and 80.

The DayStar Digital PC Interface board is manufactured by DayStar Digital, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
