Thats very cool. How are you connected, through a WIFI-232?
I want to do this with my HP-100LX one of these days.
Yes, my connection is through CBM's WiModem-232 which I believe is the eas method of getting vintage computers online nowadays. The TRS-80 Portable Computer also has a built in terminal programme which makes going online v straight forward.
Good luck in getting your little palmtop HP-100LX online! :-)

Did you post on r/retrobattlestations? There's a picture of a pristine 102 posting to a BBS there this morning.
If only you could create a QWK reader in BASIC, but you wouldn't have enough room left over for a mail packet!

Yeah, it was a pretty neat system in its time with a built in terminal and the probably the most compact acoustic coupler ever made.

But its max is 32K. But between the built-in software and the fact that the data formats tend to be VERY lean, 32K is plenty for that system.
And if you need more, they made a portable floppy drive too. Several of us have re-created that using modern hardware.
But damn, this really is a joy to type on.
Those old computers had really nice keyboards. The layout was... interesting...on some of them, but they were nice to type on.

I think acoustic couplers give you a more illustrative idea of how data
is transmitted from one device to another through a telephone line.
Even though they look absolutely archaic, they appear to run at 300
baud which is just useable for basic BBSing and data transfer. My Tandy 102 is running at 300 baud right now :-).

I'll agree the PET is a strange keyboard layout. Every time I use it
for any length of time and use a standard IBM layout I'm heading to the top right of the number pad, reaching for the backspace key.
The one thing I do love is the top row of keys all usable without using the shift key. I find it nice for BASIC. Quotation marks, $, %, *, (),
all accessible with one press.
The chicklet keyboard take a bit to get used to but actually isn't
that bad considering the size.
My favorite keyboard of all time is the IBM clicky Model M.

Look on the back of the 102 and you'll see 2 round ports. One is marked "phone". That's the built in 300 BPS modem. They probably made an acoust coupler
setup that plugs directly into that port.
I know that they made a modular phone cable that plugged into it.
There was a service called pocketmail that used acoustic coupler modems an toll-free numbers to provide mail service. I had a modem for my PalmPilot that snapped onto the bottom, and they made a Sharp organizer with a pop-o "neck" that allowed you to connect a phone handset to it. If you could fin and cannibalize one of those, they'd make a nice small coupler.

In that era, the norm was 16K. Smaller systems had only 8K.
"Beefy" PCs had 32K. But that would quickly increase to 64K and 128K and finally to 640K - which was enough for anyone (according to Bill Gates).

They are surprising how well they work. I found a few schematics online for Acoustic Couplers and I'm thinking of building one. I would like to make a really compact unit like the one for the TRS-80 102 for my HP-100lx.
I have a PCMCIA card modem for it, but they pretty much wipe out a set of AA batteries in a few minutes, and the other disadvantage is that I would need actual phone line to plug into. With an Acoustic Coupler I can connect to a pay phone if I wanted to. And if it has it's own power source I can still keep my battery life on the palmtop.
I don't know but I think that the TRS-80 102 had some of the acoustic couple hardware built into the computer.
Does yours have a another port outside of a regular RS-232?
There is a few IC chips that were pretty much a modem on a chip, and there's one that runs at 300 baud which would be prefect for a acoustic coupler.
Haha what baud rate are you using?
300 baud was always considered to be about the speed you read at - so you could read along well at 300 baud.
I used to use 300 baud (and 110 baud) on paper teletypes used with old phone systems, and I can attest to that. It was a comfortable speed to read along without falling behind.

Yeah that chicklet keyboard was a nightmare for touch typists and Commodore took a lot of heat over it. There were even a few aftermarket full keyboards made shortly after the 2001 was released. Back at that
time there were few word processors that would actually run on the 8K
PET Wordpro 1 was about the only one that was usable on a professional level. Also Commodore was late to the game coming up with a printer.
So I imagine the main interest in the full keyboards were programmers.
At the time I guess it was acceptable considering they were aiming at
the home computer market and they were testing the waters.

I am currently on 300 baud. I heard on Reddit that the TRS-80 Model 100/102 is capable of a maximum rate of 600 baud due to t type of LCD screen it has.
I have typewriters out on display as decor in my shop.
Young kids are totally amazed at watching the mechanics
and all the moving parts.
A local book store had an old manual typewriter (the same
one I used in High School) and a deck of brown paper 5x7
cards. Kids were encouraged to type haikus (or any poem) on
the cards and post them.
The kids were enthralled with the workings of a typewriter.
I remember that time and I remember several people saying that they needed a real keyboard for their PET - and they weren't programmers.
I remember one guy who was a tech wiz showing off his external keyboard replacement for the PET with the calculator keyboard.
Actually, none of the "big 3" had any idea that their products would take as they did. Radio Shack, for example, made the first run of their TRS-80 only as large as the number of stores. So if the product flopped, they co repurpose them to manage inventory in the store.
In Commodore's case, Commodore was already manufacturing calculators. So going cheap and repurposing a calculator keyboard (or 2) for their compute seemed like a good way keep costs down in case of product flop.
Years later, I had a company build a PC to my specs. The motherboard
that they chose could hold 256MB of RAM. I would have had to choose between RAM and a car at that time.
Is your old hardware still in use?
For the most part. I don't have a lot of space, so I rotate them in and
out on the table. I just finished my Kaypro projects, so that's packed
up right now. The Tandy 1400LT is on the desk where I'm rediscovering
Turbo Pascal.
You can get higher rates. But you need to run terminal software that does hardware flow control. Basically tell the other end to stop sending for a moment so that 102 can update the screen.
The terminal program that comes with the 102 doesn't do hardware flow contro

At the time everyone would have been transitioning from full keyboards also which would have made it more of a challenge too. Now most of us
have used smaller keyboards on cell phones and such. The early home computing days were such a test of the waters. It's an interesting
time. Commodore was swamped with orders and really when it came down to it, BASIC Version 1 was released full of bugs, especially the very
first ROMS with the different screen edit. The early Sanyo white key cassette drives were pretty buggy as well.

In fact.I just ordered it. The Way Things Work, by C. Van

I did my first computer class on CBM 4032s, and there were shops that made custom ROMs that we used. I suppose they left memory addresses free?
POKE to a memory address and you could do hi-res graphics, or some other add-on features, of which memory fades. I do remember doing algebraic graphing using the add-on ROM.

The keyboard is really nice and it's fairly fast.
But the screen limits the software available. Software will *think* it's CGA, but some color combinations will simply be unreadable.
It did some with some utilities that would let you reverse the LCD and change the color pallet, so sometimes you can get the software to be
usable.
Then there's the 720K limitation. No hard drive. So everything has to run off a 720K diskette. Most of the software on the Internet is made for EGA/V systems with hard drives.
Later 1400 models (like the HD with hard drive, or the FD with dual floppies but could get a hard drive) took care of that.
Supposedly the LT can get a hard drive too, but I'm still trying to make tha work.

Today, the 102 is great for taking notes in a meeting. You can build a modern version of the Tandy Portable Disk Drive and copy the notes to a

It does take a while to load a message but with the 40x8 character
screen it's not to bad as I can read everything as it's being
displayed. Like I said, I don't think I'll be able to use this computer long-term due to it being totally barebones and featureless. I'll
probably keep using it for the next week or so before removing the C internal battery and placing it into storage.
They tried to get as much into as small a package as possible (while staying price competitive).
Remember that LCD displays have only ever been made by a handful of companie so given a time frame, the "normal" screen size will pretty much all be the same. Also, color was always more expensive than monochrome, so even if the color LCDs were available, they probably weren't in general use.
This reminds me of a car museum near me. If you go there, you see many
of the high end classic cars, but very few of the 'workhorse' cars. Did
you ever wonder why? Because the people who could afford the high end classic cars could also afford to maintain and keep them in good repair.
The 'workhorse' cars tended to just be worked until junk.
The same goes for computers. Many of the old workhorse type of computers got pretty much worn out from use.

I agree. It's quite hard to find workhorse type computers used in businesses in good repair. Even something highly popular such as an IBM 5150 or 5160 is near impossible to get a hold of despite millions being produced, only the more exotic computers appear to have survived in
great numbers.
I do my best to preserve my own computers into posterity
despite lacking any real computer knowledge. My dad is a retired electronic engineer so he's able to recap or reflow boards,
remove/replace internal batteries and re-wire if necesary. The best I
can do is clean them up and make sure these machines don't die on my

Yup. Just like cars. After several years, they are "old" and
"useless". So they are thrown away. It's only many years after that
they become "classic" and deemed worthy of preservation.

I originally got into the vintage computer hobby because I started to learn how to work with electronics. My education and work was always on the softw side of things. So I wanted to expand and learn some about the hardware side.
I always suggest to people that they learn basic soldering and electronics if they want to keep old computers.
Like vintage cars, you just can't take them to the local repair place to
get them fixed. You need to be able to do some of the maintenance yourself.
The hard part of those kinds of projects is the keyboard interface. But
I have seen things that are making that easier and easier.
The next hardest part is fitting the new technology into the case.

It must have been frustrating for you if you were ever tied down to 300 baud. I cannot speed read so it's perfect for me. I think most of the general population can only comfortably read at that speed.
I've picked up a bit of an interest on teletype machines and have seen numerous people on Reddit connect them to Bulletin Boards as terminals. Most type at around 110 bits per second! They were used quite
frequently in the 1970s so I guess most of us weren't around using
these things back then. At least you'll end up with a hard copy of everything that you do :-).
There are many Arduino-like microcontrollers that will work. But every vintage keyboard is different and debugging a microcontroller is a bigger hassle than debugging your software on a computer.

The best way to learn soldering is the get some junk circuit boards and a soldering iron, maybe 40 or 60 watts and start practicing.
A junk circuit board is a great learning tool as you don't have to worry about trashing it, and you can just concentrate on soldering.
You don't need anything elaborate, just a basic iron and some good 60/40 electronics grade solder. Go for a smaller iron if you want to work with smaller parts.
That's all I use for my main iron and I've been repairing electronics for 27 years now. Most of the stuff I work on these days is old tube and early transistor equipment.
Start unsoldering capacitors and resistors and soldering them back in.
Keep the tip clean, and you'll have better heat transfer to your work.
Heat your work and feed the solder in right in between your work and the tip of your iron.
Your Dad will be able to give you some hands on pointers as well.

I'm sure you'll do well. Soldering is pretty easy once you get the hang of it.
Another thing to note is when you are soldering a part in is to keep a eye o the the melted solder, and when you see the solder flow across all your work lift the tip of the iron off your work. And just feed in enough solder wire so that the molten solder continues to flow till you have the right amount for a good solder joint.
A good solder joint should look bright, smooth and shiny.
If it looks like there are jagged edges on it, or it looks crystalline, then you need to apply more heat.

Never said he shouldn't get rid of it. But scraping it brought the company very little money when they could have sold them on eBay for much more.
That's all note I'm sure I'll make a horrendous mess of a lot of damaged/broken boards before I become competent in any way, shape or form. I sure as hell won't be touching any genuine project machines this year as they'll require a steady hand. Again, I appreciate the advoce!

The dotmatrix printers must have been the next to the worst as
far as noise was concerned. I really don't miss those machines
at all.
I've never heard any of the older Teletype or punch style printers
other than on YouTube videos. When I first started school, the Dot
Martix printers were getting phased out in favour of laser printer I
still do remember the high pitched ear-splitting noises they made.

One place I worked, I created a process where you could queue up things
to print and then, after we had left for the day, it would print everything out. We just had to make sure we had a full box of paper in the printer.
It worked out pretty good. Only a couple times did the paper get
jammed. But it did scare the heck out of the security guard one night.

Way back when, I had an old apartment with old wiring. I think the
entire place was running on 2 20 amp circuits. I had a hand-me-down
Apple Laserwriter, and I printed to it via serial port (since I had a
PC). I'd queue up a print job, printing to the printer at 9600 baud, go
in the other room, and in a couple of minutes when I saw the lights flicker, knew the printer was finally printing.
