Who said 68000? Every goddam 68xx series microcontroller, 65xx series
uses the opcodes the way Lutz does them, while Alonzo is the one that adds
the quirk. The Saturn is a Saturn, so following your conservatism, maybe
we should use HP's mnemonics. Sounds like hypocrisy to me: if you want
to bitch about Lutz's mnemonics being different than Alonzo's, maybe
you should be bitching about Alonzo's being different than HP's.

I'm not the one who started second guessing the design motives of
of each instruction set (Alonzo's vs. Lutz's), you were.

Following your reasoning, we could say that Alonzo was wrong to
have changed HP's mnemonics, after all, Alonzo's 'changed mnemonics
are no better in terms of comprehensibility or notational
convenience than the originals [HP's]', at least using any measurable,
objective set of criteria.

I happen to like Alonzo's mnemonic set, but that is a subjective opinion.
I don't think I'll switch to Lutz's, but it sort of mildly annoys me to
find out that Alonzo's mnemonics are the bastardized Motorola style,
and then you are griping about Lutz's being real Motorola style.

You accuse Lutz of 'gratuitously changing a few of Alonzo's around'.
For all we know, Lutz has been confined to the Fidonet wasteland
with a 300 bps modem, living in a shack in the Black Forest
for the past 5 years, and has never seen Alonzo's. Just because
they look similar, doesn't mean Alonzo is the one who invented
that style, and Lutz is the one who 'gratuitously' changed Alonzo's.
We all know Motorola, Rockwell had been using that style for years,
with all kinds of CPUs, controllers etc. Sheesh! Give the guy a break.
