Warm-Fuzzy

A project log for Improbable AVR -> 8088 substitution for PC/XT

Probability this can work: 98%, working well: 50% A LOT of work, and utterly ridiculous.

I'm getting a warm-fuzzy feeling reading the DOS-based multi-color 80x25-character help-screen in a program copyright late in the first decade of the twenty-first century, explicitly mentioning its compatibility with (and workarounds for) PC/XT's running at 4.77MHz, to 486's running "pure DOS", to systems running Windows 2000 through XP, in backing-up and creating 5.25in floppy disks for systems like KayPros and Apple II's.

Seriously, you have no idea how warm-fuzzy this is.

--------

This is a far tangent from this project... But actually not-so-much. In fact, I dug this guy out *to work on* this project. Though it seems I won't need it, it's a pretty amazing system that would've helped if I'd've known anything about it early-on. Suffice to say, many years ago I acquired an apparently VERY CUSTOM KayPro. I've been doing quite a bit of searching online, and it would seem there's basically nothing more than a few archived magazine-snippets, and *one* article, regarding this specific unit. Yeahp, there's a whole community (if not several), online, regarding KayPros and CP/M... People going to the effort to backup and restore images of Wordstar and things we have in *much* better functionality these days... Even people creating emulators (both CPU *and* circuitry/hardware) to use those things. And yet it would seem in the entirety of the interwebs, and amongst the entirety of those die-hards, not one has encountered this particular system, let-alone gone to the trouble to document anything about it.

-----------

Forgive my being side-tracked... But the warm-fuzzies that those die-hards--wanting to back-up and document things like Wordstar, that most people would consider irrelevant in this era--might just make it possible for someone with my utter-zero knowledge of CP/M, Z80's, nor KayPros, to document something so apparently unique... (and, yet... still usable even by today's standards!)... I dunno if I'm worthy of this experience. But I'll do my best.

---------

As it stands, I'm staring at a well-written help-screen written for DOS in 2008, compatible with PC/XT's from 1988 through Pentium 4's of the 2000's, explaining how to work with diskettes from an incompatible system from the much-earlier 1980's. It's almost like... well, I won't go into those details. Let's just say it's a nice feeling.

Meanwhile, someone left a huge pile of TNG episodes on VHS in the building's "free-section", so I've been having quite a throw-back these past several days. (Would you believe there's a couple episodes I *don't* remember having seen previously? The first encounter with Ferengis was quite hilarious.).
