Greetings! I'm hoping someone out there has some information on an
interesting semi-Apple-compatible system I've come across, called the
Laser 3000.

The most important question is: How to I connect a disk drive to this thing?
It does have two 72-pin connectors, one labeled "System Bus" which is male,
and another that is hidden behind a plastic cover and is female.

What is the pinout of the RS232 and Printer ports?

What is the pinout of the RGB and tape ports?

And lastly: What is the syntax for the unusual commands that come up when
I hit the function keys? (SOUND DEF, SOUND TEMPO, SOUND, DRAW CIRCLE, etc.)

I used a generic (Microcom) Apple ][+ clone in the mid 80's, but never
followed it after that, and never played with anything newer than a //e. Are
the ports the same as those on a IIc? Does the IIc have this (what seems to
be) 3-voice sound chip with noise generator?

Any info would be appreciated. The Laser 3000 seems to be very well built,
with an excellent keyboard, and I'm itching to make it useful.

I suspect no disk controller is built-into the Laser 3000. If so,
you may be up the creek without a paddle (the paddle being the
controller + drive combo for the L3000).



"What is the syntax for the unusual commands that come

SOUND, DRAW CIRCLE, etc.)"

As I recall from an ad for the L3000, the BASIC was a standard
Microsoft varient, rather than Applesoft compatible. Except for the
sound commands, I suspect a manual on GW-BASIC for a PC would get
you on your way.


"Are the ports the same as those on a IIc? Does the IIc have
this (what seems to be) 3-voice sound chip with noise generator?"

Having never seen a Laser 3000 in the flesh (only in ads), I cannot
say. The serial port on the IIc was either a DB-9 or a mini-din 8.
The drive port was a DB-19.

None of the Apple II series had the same sound chip as in the Laser
3000. The same chip was found in a number of other 8-bit machines,
however, and I believe on one or more sound cards for the II+ and IIe.



"The Laser 3000 seems to be very well built, with an

I wish I could run across a Laser 3000 in good condition at a decent
price. I wouldn't mind adding it to my collection of "Never heard
of it" machines. <grin>

Good luck on your quest to make it useful. I'm sorry I could not be of
more help.

So I presume this means that there is no such thing as an external
floppy controller for the Laser 128 that would be compatible with
the Laser 3000? I've never seen what any other Laser system looks
like - I guess I was just lucky to get the weird one. :)

Well, the startup message is:

MICROSOFT BASIC V.T. VERSION 2.2

(C) COPYRIGHT V.T. 1984

but it is basically Applesoft BASIC. The only differences I've found
so far, are the additional high resolution graphics and sound commands,
and the lack of low-res graphics commands. Also, I'm not sure if real
Apples use the WIDTH command to switch between 40/80 columns?

I did look up some commands in my AmigaBASIC manual, though, and
managed to figure out a few of the new commands:

DRAW HCIRCLE (x,y),radius[,aspect]
DRAW SCIRCLE (x,y),radius[,aspect]

DRAW HSQUARE (x1,y1 TO x2,y2)
DRAW SSQUARE (x1,y1 TO x2,y2)

SOUND frequency,duration,voice[,volume]
(1-64) (1-255) (1-3) (1-15)

NOISE voice?,duration,volume,frequency?
(1-2) (1-4)

I haven't figured out the PAINT command yet, nor SOUND DEF, SOUND TEMPO,
or all the arguments to the TEXT command (it sets border colours and
some other things).

I know, too, that the sound chip will play from all voices at once (else
there'd be no point in having them) and have been able to make it do so.
Until I actually specify VOLUME. After that, I'm stuck. The machine
simply waits until one note is complete before it continues execution.
Without ever specifying a volume for anything, it doesn't pay attention
to duration... BASIC waits for that length of time, but the note continues
to play afterward until the frequency played through that voice is
changed. I wonder if I can figure this out without a manual. :/

And 64 frequencies is rather limiting. Is this a limit of the BASIC, or
of the chip, I wonder?

Unfortunately, the Printer, RS232, and System Bus ports are all edge
connectors, like you find on the back of a PET. The Printer port has
20 pins (10/side), the System Bus has 72 pins, and the RS232 port has
30. The hidden port on the side is like the System Bus, only female.
And all other ports use DIN connectors. Luckily I can use the same
cable for COMP. VIDEO as I do with my VIC-20. :)

Which sound chip is it, and what other 8-bit machines had it?
What does the ad you've seen say about the L3000? I presume you still
have the ad, or have a fantastic memory? :)

much I payed for it. How's the C65 doing? ;)

"So I presume this means that there is no such thing as

You mentioned later in your message the system bus is 72 pins. I
cannot recall offhand how many pins are on the Laser 128 expansion
bus, but it was the same number as a standard Apple II slot. Hmmm...
let me open my IIgs and check.

A quick count reveals 50 pins. The bad news is, that means no plug and
go compatibility. The good news is that means a good chance all the
signals are there to hack in a IIe type controller. However, whether it
would then be recognized or not is another matter.

The problem is, I assume you don't have any of the pinouts (as few
computers come with manuals that have full tech specs...assuming you
even have the Laser 3000 manuals).

You might want to try contacting Video Technology. If they are nice folk,
they might be able to get them to send you some info on the L3000. You
never know until you try. I once got a photocopy of a manual for a printer
buffer from a company that had been out of business for years! (Long story,
but to make it short, I actually ended up talking to a "sister" company
that was in an entirely different field).



"The Printer port has 20 pins (10/side), the System
Bus has 72 pins, and the RS232 port has 30."

The printer port should be the easiest to puzzle out. Using a multimeter,
while sending a continous stream of CHR$255 to the printer, you should
be able to find the which pins are active and which are ground. (Hmmm...
but if no printer is properly attached to the ACK line, it would stop
after the first character...so much for that bright idea).

I wonder if there is more than meets the eye on that RS-232 port. Even
if one half of those pins are ground, 15 pins more than is necessary for
RS-232.



"Which sound chip is it, and what other 8-bit machines
had it?"

If I recall correctly, it is the AY-3-8910 (or something like that).
The chip, or a compatible version, was used in the TI-99/4A, MSX machines,
the Atari ST series, the Coleco Adam, and some other, rarer machines
you may not have heard of, such as the Timex-Sinclair 2068, Memotech MTX-512,
and Spectravideo SV-328 (and SV-318).



"What does the ad you've seen say about the L3000?
I presume you still have the ad, or have a fantastic memory? :)"

I am certain I still have the ad around here somewhere, as my
computer magazine collection dates back sometime. However, I was going
on memory when I posted the last message.

Uh-oh. Let me guess: Something like either a yard sale or a Salvation Army
thrift shop, and cost, around $10-$15. How close am I? If it was "worse"
than that (i.e., sitting with someone's trash for pickup, and therefore,
free), I don't even want to know. <grin>


"How's the C65 doing? ;)"

Doing well. Too bad things have been so busy I have not even had time to
turn it on in the past couple of months. (In fact, about all I have had
time to do on any of my computers recently is to try an keep up with
messages on the nets. Frankly, I think anyone who comes up with a way of
selling "free time" will be a billionaire a day after they put it on the
market! <grin>


FOUND IT!

Against the odds, I was successful in finding an ad for the Laser 3000
in a quick search while still logged on. Specifically, on page 94 of the
December 1985 issue of COMPUTE!. The company selling it was Computer
Direct (aka Protecto). Price then was $499, but that included the disk
drive, and Magic Window, Memory and Calc programs (wordprocessor, database,
and spreadsheet).

The ad also shows a pic from the back, and lists the ports. You may find
this interesting.

Looking at the back of the computer, and starting on the left side:

(1) Joystick port
(2) CP/M cartridge port
(3) Printer interface
(4) Disk drive controller interface
(5) RS-232 port
(6) Sound volume
(7) Cassette interface
(8) composite video
(9) RGB output
(10) Reset
(11) Power cord (unlabeled in the ad)
(12) Power switch

Features mentioned:

192K RAM, 32KB enhanced Microsoft BASIC, 80 column text, 560 x 192 color
graphics, 81 key sculptured keyboard, high efficiency switching power
supply, Centronics bus printer interface, cassette interface, 4 channel
sound generator. (Hmmm..I would swear it was only 3).

It went on to list the graphics modes, but those appear to be Apple II
standard.

The drive was listed as 160K capacity, but it is noted more than once that
the drive accepts Apple II software. I suspect this meant the Laser 3000's
native format was 40 tracks, vs. 35 for the Apple II series. That would
account for the increased storage.

I hope this has been of some additional help

Nope, I don't have any manuals at all. In fact, I got nothing but the
computer itself. Luckily it has an internal power supply, that takes a
normal power cord, else I might not even know yet that the machine
works. :)

Do you (or anyone else) know how to get in touch with V.T.? All I know is
that the machine was made in Hong Kong. :)

I'm not as interested in the printer port as in the RS232 and disk drive
ports. I want to get software in and out. I was actually thinking of
using the L3000 for an old-style BBS, but considering the problem with
parts I guess that would be a very bad idea. :)

Maybe the top 15 pins and bottom 15 pins are identical? (Wild hypothesis)

Cool! I guess I'll have to figure out how to bang at it in hardware, as
the BASIC seems not to want to reveal its secrets.

You are right on the mark. Salvation Army thrift shop, for $10 Canadian.
That's the most I've payed for a machine from there, but it has also proven
to be by far the most interesting.

Yeah. And then some of us have too much free time. That's why we go to
the Salvation Army to pick up new toys. ;)

Sheesh... sounds like a good deal. :) If it was available a couple of
years earlier at that price, I would've been better off buying a Laser 3000
than the Microcom ][+.

The fourth "voice" is noise.

I had no idea it had 192K, BTW. But I guess it's bank switched, as the ROM
also must be. Any idea how to access either? I'd like to verify that the
RAM is actually there, and I'd like to PEEK through the ROMs to find commands
etc.

Nope, they're not all standard. HGR5 and HGR6 have more, and different,
colours from standard Apple II modes. And text can be in colour as well:

TEXT RED,YELLOW,CYAN

for exaple gives red text on yellow background, with cyan screen border.

There are no low-res graphics modes.

>I hope this has been of some additional help

Yes, it certainly has been. Thanks for the info!

OOOoooohhh! Now I remember that machine! I was *this* close to buying
one of those. I had a Franklin 2200 at the time, and although it
was pretty much superior to all my friend's IIe's, the sound and CP/M
and RAM capabilities was making me drool. Shame about Computer Direct
(aka Protecto). They used to throw Apple II catalogs around every few
weeks, and then all of sudden they went PC and now they're ??????

I just checked my BBS list and I must have purged their name a long
time ago. From last memory, Protecto/COmputer Direct BBS was in
Illinois and had a strong Christian bent. Might want to search along
those lines to see if they are still around.

On another note, did anyone remember when the first Laser 128's
were being reviewed? There was some mention of them being able to
display something like 560x240 in DHR mode. I never saw anything
else about it, though.

In a message dated 2-18-95, you said:

"Do you (or anyone else) know how to get in touch with V.T.?"

I do not, but anyone out there with a manual for their Laser 128 should
have access to that info, and hopefully an address or perhaps even phone
number for Video Technology's U.S. office.



"Maybe the top 15 pins and bottom 15 pins are identical?"

It is possibly the RS-232 on the Laser 3000 is set up that way, as
Commodore's edge connector for their datasette used that method. However,
most edge connectors I have seen that have enough pins on one side for
the active signals put ground on the other side, so that if a flat ribbon
cable is used, every other line is ground, cutting interference and
crosstalk.

That said, such a design make make sense for a parrallel or disk drive
cable, but not for serial.



"Salvation Army thrift shop, for $10 Canadian. That's the
most I've payed for a machine from there, but it has also
proven to be by far the most interesting."

I wish our local Salvation Army thrift shops would put more "thrift" in
their computer prices. As an example, I dropped by the main one here in
Little Rock today. They wanted $40 for an old NEC PC-6001A, which had
no disk drive, only the cassette cable, and no box or manual. They also
had a "kids learning computer" of some type made by our old friend
Video Technology that they wanted $25 for.

Had those prices been more realistic (i.e. $10-$20 for the NEC and $10-$15
for the Vid-Tech unit), I would have likely walked out with both.

A couple of years ago, I had visted their North Little Rock store and
observed similar pricing.

It sounds like when it comes to acquiring old computers, I would come
out better by paying you 2x the price you pay + shipping! <grin>



"I had no idea it had 192K, BTW. But I guess it's bank
switched, as the ROM also must be. Any idea how to access
either?"

The second 64K might be accessed in the same manner as on an Apple IIe.
However, even if so, I have no idea how the third 64K would be accessed.
It could also be banked into the main 64K address space in small memory
segments, like the aftermarket mods to put 256K or more in 8-bit Ataris,
and Atari's own 130XE.

Admittedly, if you can get some tech info on this thing, it will make
your life MUCH easier. How's that for an understatement? <grin>

I went visting the very same Salvation Army thrift shop Doug
found the Laser 3000 in, unfortunately there were no Apple IIs (or
clones) to be found. I spoke with someone who worked there and apparently
they do get Apple II CPUs, on almost a weekly basis, but they're bought up
very quickly! It's not surprising, unlike other old computers, the Apple II
is expandable, user-friendly and has a vast number of educational and other
types of software written for it. As if to back this up, there were dozens
of TI99/4a's, Adams, TRS80s, Atari 400/800s, VIC20s and others stacked on
shelves. Machines that never stood the test of time as well as the Apple II
has. Hmmm, I'll admit their pricing can be a bit off, one of the TI99/4a's
I picked up to examine had a $50 sticker on it! :P

>It sounds like when it comes to acquiring old computers, I would come
>out better by paying you 2x the price you pay + shipping! <grin>

It doesn't hurt to keep your eyes open for people who throw
Apple IIs out in the trash! I've found two perfectly working Apple IIe's
in the trash, one even had a ProFile hardrive and DuoDisk 5.25. Another
had a 64k buffered Grappler+, Velcom 64k printer card, Monitor ///, Disk ][
and other goodies. Exteremly wasteful, but and even better deal than what
any thrift shop can offer -- it's free! (once you've cleaned it up a bit :)

Many people will offen just give away their old computers as well.
Such is the case with the Apple III, Apple ][ and Apple ][ Plus I acquired
not too long ago.

I do have one computer I acquired that way; a TRS-80 Model 4P.

I was in a store that sold used computers, when the guy came in
and asked about the value of it. They essentially told him "nada".
I asked him about it. Turned out someone he had already given it
to was returning it. To make the story short, a few weeks later,
I had a 4P and some software, and all it cost me was a drive
across town.

Frankly, I shudder at the thought of any computer being trashed.
Perhaps I should print up some "Send me your old, tired computers"
posters and sneak around at night pasting them on dumpsters! <grin>

Frankly, if I really knew how many old, interesting, and yes, useful,
old computers got trashbined every week, I would likely have a
nervous breakdown.

The hard part is finding these people before the terrible deed is done.
Time is short, so I cannot go around crusing the trash routes just
before pickup.

Sometimes I do wonder if I could get away with printing up some
"Send me your old, tired, dejected computers" posters, laminating
them, and then posting them on every apartment complex dumpster in the
city. <grin>

Well, I don't think there is a full side of ground pins. Some of the other
connectors do have pins that are merged together, that I assume to be ground,
but the "RS232" connector has 30 fully separated pins.

However, I now find that I am free to open this L3000. It died a few nights
ago and I was forced to break the warrantee seal in order to fix it. Turned
out to be a bad solder joint. A wire coming from the power socket had come
loose. :/ I almost died when it blinked out, though.

Well, at this Salvation Army thrift shop, it's hard to find anything of that
sort at all. Anything Apple compatible is gone before you even know it was
there. Same goes with anything made by Commodore, excepting the Vic-20,
and anything that has integrated monitors or disk drives. Basically, if it
isn't a CoCo 1 or 2, a TI-99/4A, or one of a couple of models of Atari 8-bit
system, you're out of luck. Even the VIC-20s generally have a short stay.

All machines are almost immediately stripped of any cabling, power supplies,
or peripherals as well, and it is VERY rare to find a manual for anything.
Cartridges appear occasionally, though.

I guess the Laser 3000 had people confused enough that I was able to get it.

As for pricing, I'll give you a rundown of the prices I've payed at the SA
here in Montreal:

Atari 800XL: $3
Coco 1: $5
Coco 2: $5
Vic-20 (with French manual): $5
TI-99/4A (with PS, cassette cable, RF Modulator, tape manual, half of box): $8
Laser 3000: $10
5 Vic-20 cartridges: $5

Basically, I think they base prices on how complete a system is, what quality
it seems to be to the uninitiated eye, how they feel that day, how I'm
dressed, etc. :) (When I bought the L3000, I had just had a haircut that day)

I always get the feeling that someone actually purposefully strips all
valuable stuff from them. In fact, there's a store in Montreal that sells
C64 power supplies for $20, 2-prong Vic supplies for $10... Hummm...

They don't price the units at this SA until you get to the cash (though a
few machines have prices on them - usually very high).

You probably already have all the computers that can normally be found in
this shop. Or do you want a few dozen TI-99's? :)

Well, I don't know how to access the second 64K in an Apple IIe. I always
just had a II+ clone. I guess I'll have to snoop around in some Apple
programming manuals, if the university still has any. :)

GREAT! A thousand thank-yous. Now to find out if this company considers
Canada to be part of the U.S. ;)

i'd grab the Vic and the cartridges. play video games for a while,
then strip it for parts. OMEGA RACE will always be better than Duck
Hunt.

You say an Apple II is slow? Gee, mine runs about on par with several
'286s I've seen.... oh yes, I have a command line after 4 seconds, too.
