'[OT]: Blast from the past'

On vacation down here in Trinidad (birthplace/original home),
and rummaging thru some old stuff.  It's amazing what I've dug
up -- a TRS-80 Line Printer VII, cassette tapes from my TRS-80
labelled with things like "EDTASM -- editor/assembler".  Still
need to find the actual TRS-80 itself -- 128 x 48 monochrome
graphics, baby!

Also found a book called "Computer Peripherals That You Can
Build". In it, they talk about the difference between
mainframes, minicomputers, and microcomputers, stating that
microcomputers only have an 8-bit data path.  The book is
about interfacing and building peripherals for the TRS-80
and PET computers.  Remember those?

Amazing how things have changed.

Cheers,
-Neil "now I feel really, really old" N.

Neil, wasn't the TRS-80 made by Timex.  Seems it was a copy of the "ahead of
its time" computer developed by a chap named Sinclair in England.

The TRS-80 was Tandy/Radio Shack.  Sinclair developed
the ZX80 which was followed by the ZX81, and picked up
the Timex name.  Can't remember why, but perhaps Timex
bought it for US/Asian markets or something.  Then
there was the color version called the Spectrum.  They
were neat, except the (touch) keyboard was difficult to
use, like the Atari 400.

Doing some web surfing and found this nice comprehensive
page of computer images from that era...

That was the earth shaking Sinclair ZX-81...got one of those somewhere.
Using the wall wart from it right now on my pic programmer ;-]

My first machine was the Times Sinclair 1000. Still have it! 2k of ram with
a membrane keyboard. Upgraded to the Vic-20 > C64 then IBM XT. Kept one of
each. I did a homebrew Z80 somewhere in there also, CRT and the works. I
remember at the time I saved up $125 dollars to buy just the Z80 CPU.

Really makes the SX seem racey, eh?

TRS-80 was Tandy's generic name for all their systems.  Model I, II, III
... Color Computer I, II, III, etc.

I think you're thinking of the Timex-Sinclair 1000 (distributed on this
side of the pond by Timex) which was a tiny little thing that had a
membrane keyboard, ROM-based BASIC, and TV/RF output.  I taught my
grandmother to program in BASIC on that thing, if you can believe
that... just to prove anyone could learn how to operate a computer and
even program it.  We wrote a little recipe tracking program, but without
any storage it had to be left plugged-in all the time.   LOL!

I had Color Computer models when I started computing... "CoCo" was a
wonderful machine... 6809E was a good micro to learn assembly on!
(GRIN)  And Microware's OS/9 was (and still is) and excellent true
preemptive-multitasking operating system.  Far ahead of its time.

(And just by dumb luck I ended up working on commercial OS/9 systems
later on... telephone system stuff...)

Had a CoCo I, II, and III at various times... and later inherited a
family member's TRS-80 Model III.  Two years ago I fired up VisiCalc on
it from floppy... ran just as fast as Excel.  (GRIN)

Ahh well... the days of the BBS...

I had been hoping that the Model III had a serial port (that was a $500
option back then...) -- I was going to take it to the office and hook it
to the console port of the Sun at my desk... just to freak people out.
But it didn't.  I found a guy in Texas still has a warehouse full of
them (or he did a few years ago) complete and in their boxes, brand
new... surplus from Tandy years ago.  I could have bought a replacement
for $20 WITH the serial port!  Still new in the box.  Don't know if he
still has them...
