About influence on PC and ASCII

Latest comment: 10 days ago2 comments1 person in discussion

The Datamaster is EBCDIC, therefore there can't be a direct influence over ASCII. I cannot deny influence on later IBM systems with similar charsets, but not over the IBM PC as it is the first IBM computer having ASCII charset. Buran Biggest Fan (talk) 11:40, 8 March 2024 (UTC)Reply

Maybe the font could be considered as an influence. Still, there are many points to consider:

Not all characters are provided by the character generator ROM, some are provided by the Intel 8275 it uses.
The Datamaster misses the character '1' (one) and reuses the character 'l' (L).
The characters are not written in the ROM in any unknown encoding (no ASCII, no EBCDIC) so EBCDIC conversion is made before writing the character codes in the video memory.

I can provide the external link of the thread where this is discussed if anybody wants. As a colleague said, in the last six months there has been more breakthrough in the Datamaster than in the past twenty years.
