9 The program {\tt monitor.asm} is a program that is intended to be included
|
|
|
10 in the ROM of a 6809 based single board computer. The program allows a user
|
|
|
11 to communicate with the single board computer through a serial port. It
|
|
|
12 allows a user to enter machine code, examine memory and registers, to set
|
|
|
13 breakpoints, to trace a program and more. Furthermore, data can be sent to
|
|
|
14 and be received from the single board computer through the X-MODEM protocol.

16 \section{A bit of history.}
|
|
|
17
|
|
|
18 In the seventies you could buy single board microcomputers that had a
|
|
|
19 hexadecimal keypad and 7-segment displays. These computers typically had
|
|
|
20 less than 1 kilobyte of RAM and a simple monitor program in ROM. An
|
|
|
21 interface to a cassette recorder (or paper tape reader/writer) and a
|
|
|
22 terminal was possible, but not standard. The typical way to program the
|
|
|
23 machine was entering hexadecimal machine codes on the keypad. Machine code
|
|
|
24 was the only language in which you could program them, especially if you
|
|
|
25 only had a hexadecimal keypad and 7-segment led displays. You typically used
|
|
|
26 these machines to experiment with hardware interfacing, as games and
|
|
|
27 calculations were a bit limited with only six 7-sengment digits.
|
|
|
28
|
|
|
29 Next came simple home computers, like the TRS80, the Apple ][ and the
|
|
|
30 Commodore PET. These machines had BASIC in ROM and they used a simple
|
|
|
31 cassette recorder to store data. These computers had a TV or a low quality
|
|
|
32 monitor as display and a QWERTY keyboard. These machines could be upgraded
|
|
|
33 with a floppy disk drive and a printer and then they could be used for
|
|
|
34 professional work. These machines had 4 to 64 kilobyts of memory.
|
|
|
35 Apart from assembly language you could use BASIC, Forth
|
|
|
36 and sometimes Pascal to program these machines. Most useful programs (and
|
|
|
37 the best games) were programmed in assembly language. Many of these machines
|
|
|
38 had BASIC in ROM and no machine code monitor. You had to load that
|
|
|
39 separately.
|
|
|
40
|
|
|
41 Today we have personal computers that run DOS, Windows, Unix or something
|
|
|
42 else. New computers have 4 to 16 megabytes of RAM and hard disks of more
|
|
|
43 than 500 Megabytes. Apart from having in the order of 1000 times more
|
|
|
44 storage, they are also 1000 times faster than the old 8-bit home computers.
|
|
|
45 Programming? You can use Visual BASIC, C++ and about
|
|
|
46 every other programming language on the planet. But programs have become
|
|
|
47 bigger and bigger. Programming is not the same as it was before.
|
|
|
48
|
|
|
49 I guess there is some demand for small 8-bit computer systems that are simple
|
|
|
50 to build, easy to interface to all kinds of hobby projects, fun to program
|
|
|
51 and small enough to integrate into a home-built project.
|
|
|
52 Do we want to use hexadecimal keyboards and 7-segment displays? I guess not
|
|
|
53 many people want to use them. Do we want to use a cassette recorder for data
|
|
|
54 storage and a TV as a display? Not me. And if you build your own 8-bit
|
|
|
55 microprocessor, do you want to waste your time and money on a hexadecimal
|
|
|
56 keypad or a cassette interface that you do not like to use and that you do
|
|
|
57 not need anyway? PCs of five years ago are more than adequate to run an
|
|
|
58 editor, a terminal program and a cross assembler for your favourite 8-bit
|
|
|
59 processor. If you equip an 8-bit system with some static CMOS RAM, a serial
|
|
|
60 interface and a monitor in ROM, you can use the keyboard, hard disk and
|
|
|
61 monitor of your PC for program development and the 8-bit micro can be
|
|
|
62 disconnected from the PC and do its task, once it is programmed.
|
|
|
63
|
|
|
64 Cross development is nothing special. How do you think the microprocessor in
|
|
|
65 you microwave was programmed? But it is not practical for a hobbyist to
|
|
|
66 program an EPROM for each program change. Professional developers of
|
|
|
67 embedded processors have expensive tools, like ROM emulators, processor
|
|
|
68 emulators etc. to see what the processor is doing on its way to the next
|
|
|
69 crash. For a hobbyist it is much more practival to have a slightly more
|
|
|
70 expensive embedded computer that you can run an interactive debugger on.
|
|
|
71 And you are not even limited to assembly language. If you have 32k ROM you
|
|
|
72 can have both the monitor program and a BASIC interpreter and some
|
|
|
73 aplication code in ROM. Nothing prevents you from having Forth as well.
