Micro and Mini : A Love Story
Micro was a real time operator and dedicated multi-user. His
broad-band protocol made it easy for him to interface with numerous
input/output devices, even if it meant time sharing.
One evening he arrived home just as the sun was crashing, and had
parked his Motorola 68000 in the main-drive (he had missed the 5100
bus that morning), when he noticed an elegant piece of Livewire
admiring the daisy-wheels in his garden. He thought to himself, "She
looks user-friendly. I'll see if she'd like to update tonight."
Mini was her name, and she was delightfully engineered with eyes
like COBOL and a prime mainframe architecture that set the micro's
peripherals networking all over the place.
He browsed over to her casually, admiring the power of her twin,
32-bit floating point processors and enquired "How are you
Honeywell?". "Yes, I'm well", she responded, batting her optical
fibres engagingly and smoothing her console over her curvilinear
functions.
Micro settled for a straight line approximation. "I'm stand alone
tonight", he said, "How about computing a vector to my base address?
I'll output a byte to eat, and maybe we could get offset later on."
Mini ran a priority process for 2.6 milliseconds then transmitted
8K, "I've been dumped myself recently, and a new page is just what I
need to refresh my disks. I'll park my machine cycle in your
background and meet you inside." She walked off, leaving Micro
admiring her solenoids and thinking, "Wow, what a global variable, I
wonder if she'd like my firmware?".
They sat down at the process table to a top of formfeed of fiche
and chips and a bucket of Baudot. Mini was in conversational mode and
expanded on ambiguous arguments while Micro gave occasional
acknowledgements although, in reality, he was analyzing the shortest
and least critical path to her entry point. He finally settled on the
old "Would you like to see my benchmark subroutine?", but Mini was one
step ahead!
Suddenly she was up and stripping her parity bits to reveal the
full functionality of her operating system software. "Let's get BASIC,
you RAM" she said. Micro was loaded by this stage, but his hardware
policing module had a processor of its own and was in danger of
overflowing its output buffer, a hang-up that Micro had consulted his
analyst about. "Core" was all that he could say, as she prepared to
log him off.
Micro soon recovered however, when Mini went down on the DEC and
opened her divide files to reveal her data set ready. He accessed his
fully packed root device and was just about to start pushing into her
CPU stack, when she attempted an escape sequence.
"No, No!", she cried, "You're not shielded"
"Reset, Baby", he replied, "I've been debugged."
"But I haven't got my current loop enabled, and I can't support
child processes" she protested.
"Don't run away" he said, "I'll generate an interrupt."
"No. That's too error prone, and I can't abort because of my
design philosophy."
Micro was locked in by this stage though, and could not be turned
off. But Mini soon stopped his thrashing by introducing a voltage
spike into his main supply, whereupon he fell over with a head-crash
and went to sleep.
"Computers", she thought as she compiled herself, "All they ever
think about is hex."
