I updated my Flash Drive and tried it successfully on both my 4052 and 4054A!Ok, I have updated BSAVE to round the file length to the nearest 256-byte block. A test to load a program and BSAVE it to a new file, then load it again with BOLD was successful. A call to BAPPEN to append the saved file to an existing program also worked. I have attached the resulting binary file saved on the SD card.
I tried both with and without the FF at the end of the data. The version without the FF did not work and returned a MAG TAPE ERROR.
I have posted version 0.05.83. Hopefully it will work on the 4054 and 4052 although there are still unanswered questions in my mind.
I did not use your BSAVE-output.zip file.
On both my computers I BOLDed the 3-line test file I've been using, then BSAVEd it to a different file number.
Then BOLDed the new file number and listed all three lines as expected.
Then BAPPENded the new file number on line 1000 and got the five lines expected.
I also ran PICTURE menu on both computers and the Binary READs worked fine.
Then I changed to OPT30DEMO directory and BOLDed BINARY pgm 5 (Pacific Coastline) which is from my tape capture.
No hangs, no error messages.
I just posted this version on my repo.
