I wrote in 8086 assembler for the 8086 board I designed. It wasn't any

You are having a laugh...

I actually assumed he was just trolling, because surely even he isn't
*that* crazy.

x86 was awful, it really was. Didn't its choice largely stem from IBM

Was? it still is (from a developers point of view).

The good news is that I haven't written any assembler since the PDP11, and
when I looked at the '86 out of idle curiousity, it made me nauseous.

Well to be fair, its exceedingly rare that one needs to dabble with
assembler... Only had to do it once seriously on '386 stuff and that was
for built in test code on a 386 platform when there were no compilers
capable of generating protected mode code available for it at the time!

Used to routinely do comms stuff in 8086 assembler when writing the main
app in Turbo Pascal 3[1] - but that was because the language at that
version lacked the ability to do interrupt handling etc. Once version 4
or 5 became available that was no longer needed.

[1] Ah, the fond memories, an astoundingly fast and good compiler,
editor, and run time environment that all fitted in 50K on a floppy!

The number of times I have actually needed to code in assembler for
performance reasons, can probably be counted on two fingers in the last
twenty years! Once was the bitstream coding stuff on a system with very
tight and had real time limits. The other was for a Win 3.1 device
driver that let you do synch serial comms with no extra hardware on a
bog standard PC!

These days the horror of the '86 is hidden away several layers below. Hell,

Indeed.

Still handy now and then to be able to drop a debugger into disassembly
mode and look at what is *really* going on though! ;-)

I haven't written any *compiled* code for years, never mind assembler. These
days I do anything complicated in Perl.
