The MC1000 is an letter shoot or pneumatic delivery (german "Rohrpost") on a Intel 8039 CPU. The MC1000 are developed and destributed from 1982 until end of the 80th.
These repository will be stay for all homebrew software for these PCB like an Arduino.
- INTEL 8039 8bit CPU
- INTEL 8251 UART
- INTEL 8279 Keyboard/Display Interface
- 2 x INTEL 8243 Input/Output Expander
- Program on 2716/2732 EPROM
- Program memory extendible to additional 2716/2732 EPROM
- 4 digit 7 segment Display
- 12 keys Keyboard (0-9,*,#)
- 20 GPIO Input ports by opto-isolator
- 17 GPIO output ports by opto-isolator
As Assembler i provide the TASM for the 8039 uC. I also provide the dasm (crossplatform) as second source.
I prefer the TASM (under Windows) and therefore all the *.src files are developed with the TASM syntax, because i got additional an *.lst listfile (could not find HowTo with dasm).
- Append the path where the TASM executable located to the system PATH variable.
- Create a new system variable TASMTABS with the path for the TASM *.tab files
See: TASM Manual
For execute the TASM, use the go.bat batchfile.
Syntax: go.bat <sourcefile>
If you use UltraEdit as Texteditor for assembling, you can import the 8039wordfile.txt for Syntax highlighting.
