'[OT]: Blast from the past'

TRS-80, Model I, VIC-20, C64... What I remember about these is the sound of
the program/data "screaming" into the computer from the cassette deck. Also,
I remember entering programs by typing in hundreds of rows of 8-bit, HEX
digits followed by a checksum. I would have my girlfriend read me the
numbers while I typed. She wasn't a geek/nerd, and in retrospect this was
probably a bad move on my part. I'll just have to assume.

I remember the year my wife gave me an external hard drive for my C-64.
Thought I had died and gone to heaven :))

Same feeling here when I dragged the whole TRS-80 Model III
(the one with the built-in monitor) back to the U.S. to get
it upgraded (from 16k) to 48k -- fully decked out!!!

Later, there was the dual disk-drives.

At this point, I still didn't know what hard-drives were.

And at a later point, I added a third-party graphics board
which brought the graphics to 384 x 196 (IIRC).  Sweet!

Since my original posting of this thread, I've found some
floppies from my Commodore Amiga.  The original 1000.  But
that was MUCH later than the TRS-80.

Cheers,
-Neil.

Neil, come to think of it, I believe it was a disk drive, not a hard drive.
Been a long, long time.

BTW, where are you?

Still have the TRS-80 Model 1, low serial numbers....complete with the
expansion interface, 4 5-1/4" drives,modem.....think we had 128K memory in
it too.

I fondly remember my own TRS-80. Model 1, Level 2 (16K RAM).
I built my own interfaces and was using it as my first home
automation controller back then.
The development cycle was horrible: Load EDTASM from Cassette,
then load the source code from another cassette, Edit, compile,
save Source to cassette, save object to another cassette,
reboot, load object and run. Reboot and repeat cycle from above.

>Later, there was the dual disk-drives.
I never had that luxury.

I still do most of my "desktop" development for Amigas.
I find them much more stable and programmer friendly than the
various windows offerings. Once a program is complete, I
usually move it to one of (many) Amiga 1000's that I have
on hand, all with Kickstart in ROM and most with hard drives
attached.

Not just home automation, I have also installed a few Amiga
1000s for industrial controls or user interface. Even systems
that boot from floppy are very reliable.

I'm just hoping that one day we'll get the Amiga OS ported to
a more common hardware platform. It's still the easiest, most
reliable OS I have ever written for.

We got one of the first TRS-80's in the Florida and one of the first
projects was to interface to a Teletype Model 15 printer, since that's all
we could afford at the time! Talk about the past! The manual for the Model
15 provided instructions on how to destroy the printer in the event you
were overrun by the enemy!

I had a TRS-80 Model 1, originally came with Level 1 Basic, 4 KB of RAM and
a cassette interface for programs and data, and a clock speed of about 2
MHZ...

I built an EPROM programmer, copied the Level 2 Basic PROM from a friends
unit and 'bulked up' my machine to 48 KB (without buying the expansion
unit)...

Also added a mainframe printer I bought at a flea market (after making a
centronics compatible printer interface for my TRS-80); the printers manual
boasted that the internal 2 KB of memory could double as online storage for
the host system...

But my first "PC" was an RCA COSMAC 1802 based Elf unit, with 256 bytes of
RAM, no prom and a hex kepad and display (not bad conisdering contemporary
hobby PCs were still using LEDs and toggle switches for each address and
data bit).

Those were the days.  :)
Bruce.
