Subject: ADFS Broken Chain - BBC Model B

I have a BBC Model B wiith RetroClinic DataCentre

I have a "broken directory". 
I have written a load of stuff on the CF Hard Drive, and really would like to 
recover it, rather than reformat the hard drive and lose it. Needless to say it 
is not all backed up.

Has anyone written a program to fix broken directories, or know how to fix them 
manually (I have ADT installed).

Thanks, in anticipation

Peter England

To: bbc-micro@...

Sorry to annoy you all ... I'm sure I've read this before, but I can't 
find it.

*TIME on the Master I'm rebuilding produces a corrupted string. Is there 
an easy way to uncorrupt it? The hour/min/second fields are updating 
correctly, so the internal clock seems to be working. I juat need to 
force it to add the day and date in the right format.

(Ok, it doesn't have the post-Y2K fix, so I know it'll be a hundred 
years out of date. Hey ho.)

All the best,

Kris.

Done some work and wrote the beginnings of a test suite - to test for 
basic register interactions, addressing modes, and branches. This 
allowed for me to tweak a number of issues in the CPU core so...

...great news! The emulation no longer crashes. The log (from v1.33 
firmware, but 1.31 and 1.40 are similar) now has this bit:
--8<--------

--8<--------

And the last three lines repeat ad finatum.


I will not do anything re. the FDC or HDC hardware as I want to create 
more parts of the test suite, make sure the emulation is correct...


I have updated the release and source with the changes.


Now to unwind with a movie. :-)


Best wishes,

Rick.

If you're writing your own 6502 tests, there might be no need -- there's a
6502 test suite on the model-b page:

http://www.modelb.bbcmicro.com/tech.html

Very easy to bodge into an emulator. The linked-to mailing list post
explains what to do.

I once had a Spectrum in a "Lo-Profile" keyboard which looked lovely,
but I never used it before I eventually eBayed it.
