Thanks guys!

Wow ! Nice work !

Muchas gracias Rob

Do you love me ???



Finally I didnt burn it !

I have alot of hardware papers I want to get rid off if you want them, keeping only my omn works (mainly software).

Found this also, but just this ad :

Hi,
I have just sent a PM to you

cheers
pere

Mon dieu! This is awesome news!

Please scan everything when you have time.

Best regards,

The Floppy system :



40 tracks up and 80 tracks down, both double sided :
Stupid green LED added for being light on pair or impair tracks, cant remember



The "doubleur d'impulsion" allowing to use a 80 track floppy as a 40 tracks one :



Supplies :



Theses times were hard for us

Finally posted the 4/4 pages of the ANDTEK board up there. 3 post before this one so.

Also using a personal software, I tried to upscale Dragon's screenshots on printer for artificial better resolution. Result was interersting but not perfect :

I made in 6809 assembly code a compute of 1000! = fact(1000) :

Here in hexadecimal, notice all the "0" at the end of the number :



Producing in decimal takes much more time than computing in hexa ! :



And here, the end of 3000! in hexa, and 3000! in binary, as I was storing my numbers in memory its was easy to have them on memory screen !! So I was watching in real time at my number growing in binary during computing



Theses software are somewhere in the pack of old disks I have.

Found 80 col Flex and 80 col OS9 disks in my stuff.

Will test my Dragon 64 soon, and if my DDOS controller is still disabled could someone lend me a controller ? For sort my software.

And how do you use 3,5 floppy with a Dragon please ?

TY
Manu.
