text_A: Developers of applications had a hard time when writing programs in 6301 assembler, because the machine had only 2 kB of RAM and came with no operating system. Another difficulty for developers was with the performance limitations of the earliest DATAPAKs, which used a serial-access internal architecture, as opposed to random access. Retrieving, for example, byte 2000 from a DATAPAK meant issuing successive hardware commands to either step from the current read position one address place at time until position 2000 was reached or, in the worst case, resetting the read position to zero and then issuing a step-forward command 2000 times.
text_B: Would someone who had studied in an early computer-science program at a top university be able to start working on this machine out of the box, because its operating system would be one that had been used before?
NO.
