Have you ever owned a one piece computer system?

Only some laptops with LED or LCD screens, where this problem with
magnetic fields doesn't exist. I always thought 1-piece computers
systems with CRT displays either were too bulky or had a screen
too small.

Full blown laptop computers with LCD screens didn't exist back in the
late 70's/early 80's.

I know..... there was only the Osbourne, with a small CRT display....

And don't forget about the TRS-80 Model 4P. The P standing for
"portable" since it only weighed about 25 lbs : )

If you were around and able to use a computer back then you had
no choice.

Sure I had a choice! My choice was to use only desktop computes... :-)

Those systems were
designed to work that way so there is no reason people shouldn't have
bought one. Just about every high end serious business computer was
all one piece with either 5.25" or 8" floppy drives back in the early
80's.

...I don't think so. CP/M machines were the most common micros used
by businesses back, and they usually had a separate terminal. And
minis and mainframes (which were the most serious computers back
then) _definitely_ had separate terminals !!!!

We're not talking about terminals, mini's and mainframes.

You were talking about "systems" -- they include mini's and mainframes,
which back then was dominant among serious computer users, who often
regarded micros as just toys....

I guess system can mean a bunch of different things...I consider my
Emachine that I'm typing this message on to be a system. An no wise
cracks about the E...out of the dozens of computers I've owned it's
been the most reliable : )

I can give you a mile long list of popular systems (most CPM
compatible) that were all in one, including every TRS-80 (model II,
III, 4, 4P, 12, 16), Kaypro's, Osbornes, macs, ect.

What business systems from 1982

Was Trash-80 really a _business_ system?

All except the CoCo's. The model I was more of a ground breaking
hobbiest system. The III's popped up everywhere from homes, schools
and businesses (I still laugh everytime I watch Airport and see the
III's at the terminal). The 2, 12, 16 were very expensive heavy duty
office type systems not designed for home use. They used the big ol'
8" floppies and were available early on with hard drives. I think a
few of those depending on options hit well over $10 grand.

I owned a very basic 16K cassette based model III. It was $1,000 plus
the cost of the cassette recorder. Fully loaded with dual floppies,
48K, RS232 board and Orchestra 90 sound board brought the price up
towards $3,000.00. I eventually got there but only after all the
parts were heavily discounted. I know the original price of the Drive
0 kit was $1,000.00 alone.

and earlier do you recall that used a separate CPU, keyboard and
monitor? Something that you would walk into a persons office and
see sitting on a desk?

The Altair, IMSAI 8080 and most S-100 computers, including brands
advertised specifically as business computers, such as the North Star >Horizon. And, of course, the Apple II which got used as a business
system too........ and the Apple ///....

I'll give ya that...I'll say there's a fair share of both.

Later the VIC-20, Commodore-64, Sinclair ZX-80, ZX-81 and Spectru,
the Jupiter Ace and many more appeared, which had separate displays.
But they were not business systems.

Considering when they were released I never understood why the C64 and
Atari 800's never made it as real business machines? I would say
either one was able to hold it own against the first 4.77 mhz XT's and
they cost a fraction of the price.

At the very beginning, IBM considered the PC to be a game machine for
home use.....

BTW the XT had a hard disk (10 MBytes -- tiny by today's standards but
enormous back then), which probably partly explains why the XT was so
expensive (the other reason it was so expensive was of course the
brand name "IBM". Otoh, when Apple released the Lisa, and later the
first Macs, they did the same thing: these were _not_ cheap machines!).

Leaving *any* kind of magnetic storage on top of a television is never
a good thing. I'm not sure why Coleco specified a colour television
either. All TVs, to my knowledge, play around with magnetic fields,
and can damage magnetic media.

Which is why you should never get some models of the Apple Macintosh:
a CRT display as well as a floppy and a harddisk inside the same

Never thought of that... is it an actual issue, or just a percieved one?

Actually it isn't. Most floppy drives are shielded anyway, plus they
add shielding between the components that are susceptible to the
magnetic fields inside the case. If you are concerned, simply remove
the cover and if the drive is not encased in itself, then it probably has
a piece of coated paper between it and the CRT.

The hard drive was an option on most of the XT clones. Not sure if the IBM
was available without it or not. Back in the mid 1980's a lot of home users bought a bare bones machine and added a hard drive later. By buying an RLL drive controller card instead of an MFM card, you could end up with 35 megabytes of drive space for the price of a 20 megabyte drive. :-)

I did the RLL thing...it worked great with certain drives. I was able
to squeeze 32 megs out of an MFM drive that way. Sleazgates just
wouldn't fly with that trick though.

I used a 20 meg MFM Seagate with a Western Digital RLL card. I did have to
do a low-level format to get it to work though. This was after Seagate
started including install software on a 5 1/4" disk in the box with their drives. The software made low-level formatting easy.

I loved the BBS's back then and how each would brag in the opening
screen about the amount of online space they had. I remember being
blown away when "Last Chance" upped his to 85 megs!

I remember one BBS using five 286's networked together. With two 50 meg
drives in each box. He had five phone lines and a modem in each computer
for a 5 node system. One line was free (and _always_ busy). It was worth
ten bucks a year to become a subscriber and be able to connect on the other four lines.

Percieved.

Perceived.

The old toaster Macs did have a warning about placing an external floppy
drive on top of the computer, or on a stand beside it at the same level
as the monitor. The internal drives were never a problem of course,
since the designers _knew_ where they would be.

Well,
the crash took place from 1983 to 1985. Read how many millions Atari
lost in 1983 and 1984 (until the Tramiels took over; the losses were
smaller then and somewhere in 1985 Atari was on the plus side again).
Some companies already got busted in 1983, some survived until 1984.
think, after 1985 the great homecomputer crash was over...

That's because of the great computer/video market crash of 1983, when alot of companies went under!

Actually, the crash was the following year, 1984.

Actually, it was the year after that -- 1985. I remember because of
Live Aid. :p

If it has anything to

do with display, the VIC (Video Interface Chip) in the C64 was the most advanced display processor available in a low cost home computer in 1983.

Yeah - those 16 colours really were advanced in 1983. All the Atari
computer owners are probably laughing their asses off at this statement.

The C64 was one of my favorite systems. Best developers, best games,
terrific sound. But your statement above is SILLY.

You seem to be forgetting that sprites were implemented in hardware, as well
as collision detection in hardware, and other nifty features. All of which explains your statement above about the C64 having good games. :-)

The 9918/28 had 32 hardware sprites and 16 colors. Long before 1983

Sprites and collision detection were done in hardware on the Atari 8-bits, too!

C=64 sprites seemed to be more versatile 'out-of-the-box', but there were some pretty damned
cool tricks you could do with those screen-length (e.g., ~200 pixel tall) 'players' and 'missiles'
on the Atari, too. ;)
