REQUIREMENTS AND RESTRICTIONS
Minimum Hardware
The Z80185/195 Development Board can be used with a dumb terminal and a power supply;
however, a PC is recommended to take full advantage of the development kit's software downloading
and development capabilities.
If Using a PC
Any IBM PC (or 100-percent compatible) that can run MS-DOS V.5.0. We recommend an IBM PC (or
100-percent compatible) 386-based machine at 20 MHz with 4 MB RAM, hard disk drive (with 1 MB
available), and a 3.5 floppy disk drive (see "Notes" that follow).
Minimum Software Operating Systems
MS-DOS V.5.0 (see "Notes" that follow)
Additional Items Not Supplied with the Support Package
A source of power (+5 VDC
±
10%) can be used in place of the PC. This can be a laboratory power
supply with supply current of 1.0A.
Notes:
1. Debug Monitor with a Dumb Terminal.
Two Debug Monitor commands (“L” for loading a hex file
and “N” for changing the Serial Data Rate) will not properly function when running on a dumb terminal
(refer to Chapter 3: Using the Debug Monitor, “TZ Program Restrictions”).
2. TZ Terminal Emulation Program. The TZ Program, which is included on the Z80185 Sample
Files and Monitor Source Diskette, was developed to run with MS-DOS V.5.0; however, the program
may run on earlier versions. One (or more) copies of the TZ Program will run under Windows 3.1 (and
also may run under earlier versions). The kit includes .PIF files on the Z80185 Sample Files and
Monitor Source Diskette to help start the TZ program in the Windows environment.
3. PC Models/Serial Baud Rates. The maximum serial rate that can be used between a PC and the
development kit board is dependent upon which PC model and configuration that is used. If the baud
rate is too fast for the PC, characters will be lost during lengthy display sequences initiated by the
monitor program D, U, or F commands. Also, downloading may fail if the serial rate is too high.
General Guidelines:
PC Configuration Maximum Baud Rate (bps)
286 or 386 (slower) 19,200
386 (faster), 486, Pentium 57,600
486 (faster) and later generation 115,200
machines with serial drivers and
receivers rated for higher baud rates.
