[alt.hackers] the TRS-80 destroyer

Here's Todd's, slightly shorter, but not the best:
       (while (setq inhibit-quit t))


Try this minimal five char sequence on a model-1 trash-80
(if i remember correctly--maybe the two lines are switched):
<tab>'<cr>'<cr>

REMember, the apostrophe is an abbrev for REMark.

Hangs it, if not reset; maybe starts writing the stack into video RAM.
It's back home in Illinois, so I can't test it now.  My Mom was still using
it until this summer, running a payroll program that I wrote 10 years ago.
Certainly my longest existing, used program.  When I had a plotter hooked
up to it, I had a BASIC program which would print out the records, using a
vector font I designed.  Took about 30mins/page, but gotta keep these
machines busy.  An idle cycle is the devil's workstation, or whatever it is
they say.

Now I have a machine on my desk with 1000x more RAM.  How times are changin'.

I think that's:

<spc><spc><spc>'<cr>'<cr>

but it's been a while (still in the closet).

When I was in high-school, I noticed these programs that would let you use
funky bitmapped fonts for your MX-80 and really wanted to be able to do that
but the price!  $150 for a stupid program?  No way man.  Crafted one up
via Z-80 and it worked rather nicely (wasn't great code but...).  The
best part was that "80-Micro" published the article *and* payed me for it.
Kinda neato, you know?

ObHack: I'm working on a Trs-80 Model I Level II `simulator.'  I use that
term, rather than emulator 'cause I'm going to copy my ROM rather than
emulate it (in the proper clean room fashion).  Hope RS doesn't mind (for
my personal use only, of course).
