I recently bought a lot of old LEGO dacta teaching materials from the 80’s, among them book 950036 which is a ring binder from 1987 containing pages of documentation in Danish for programming the LEGO 70455 “Interface A” box from a Commodore 64/128 computer. There is no ISBN.
I have scanned the book and you can get it from here (140 pages, 56 MB). Please report any errors to me.
NOTE: At least 14 pages are missing, but I have copied them from the almost identical book 960037. For the project pages, the only difference between the books seem to be the keyboard key names, and these are not referenced on the missing pages.
Accompanying this book are two floppy disks with software for Commodore 64/128 computers and sample programs for the projects in the books.
The disks have been ripped and you can get them from here as D64 images:
The first two files are the original dumps including bad sectors. All bad sectors ought to be outside any data areas but in case you need disks containing no bad sectors (e.g. for copying), the last two files are identical to the first ones except that all bad sectors have been marked as good. Many thanks to Carsten from retro-commodore.eu for helping out.
You can load the software from the program disk with
LOAD"*",8
RUN
As I don’t have a real computer to test it on, the software is currently untested. Please contact me if you get the software running.
About the restoration:
The pages of the binder are photocopies, and due to some chemical process occurred during storage for many years (most likely a reaction with the plastic of the binder), the ink on the last pages have become sticky, and the pages stick together, almost impossible to take apart without destroying the print. Partially soaking the pages in IPA, I was able to pull them from each other with only slight damage, but a lot of graphical work have gone into restoring the contents. You can see similar examples of restoration on my page for book 9760.
