Now, it works more:

6809 EXTENDED BASIC
(C) 1982 BY MICROSOFT

OK
10 A=0
20 B=0
30 PRINT A
40 ? B
50 PRINT "H E L L O "+"WORLD!"
60 PRINT "X"+STR$(A)
RUN
 0 
 0 
H E L L O WORLD!
X 0
OK

A other number than 0 results in a loop...

Seems that's the easter egg. Found this: http://www.pagetable.com/?p=43

jedie

If you run CLS with a higher number than 8, you will see the Microsoft copyright line. Why?

A Easter egg or a error?

jedie

Yes you are right. I connected the dragon and test it. It switched to greyscale and it's clearer.

I didn't not see any significant difference between 32 and 64 screen output.

jedie

I have a Dragon 64 here, buyed on ebay... Now i see there is a mod.

There is a condenser connected parallel to the "quartz crystal" XL2. See picture on the right side.

What does it do? Change the frequency pulse?

And after another bugfixes, a first "HELLO WORLD" works!

Code: Select all

6809 EXTENDED BASIC
(C) 1982 BY MICROSOFT

OK
PRINT "HELLO WORLD!"
HELLO WORLD!

Works with Multicomp6809 and Simple6809 ROM (think the most code of the ROM are the same

)

other code results in a loop...

@sixxie: IMHO you should add information about linux binaries on the Windows/MacOS download list. I found the information in a old post: There is a debian testing package for amd64 - apt source here: deb http://www.6809.org.uk/debian testing main deb-src http://www.6809.org.uk/debian testing main bt...

btw. maybe it would be better to look for a TFT TV and not TFT-Monitors with composite?

jedie

@zephyr: That's too much machine code for me

I improved the look, by using lowcase / inverted letters. Looks like this:

Source code is here: https://github.com/jedie/PyDragon32/blo ... C_NEGA.bas

It's a CC test with NEGA

jedie

The last bugfixes results in a different output:

Code: Select all

6809 EXTENDED BASIC
(C) 1982 BY MICROSOFT

OK
PRINT "HELLO"

OK
PRINT 123

OK
10 PRINT 123
LIST
OK
RUN
OK
FOR I=1 to 3:PRINT I:NEXT I
?SN ERROR
OK
PRINT "NOTHING WORKS :("

OK

But, yes no BASIC code seems to work, yet
