A Sony digital voice recorder in SHQ mode is a much better solution compared to
a CCR-81. Fits in your shirt pocket and doesn't require tapes, or rewinding, or
finding the proper location on the tape, hours and hours and hours of storage.
I use one for loading Romulus Chess on my 200. And occasionally I take it for a
backup just in case. It's reliable but really slow.
Everything else I use my Phone.

CCR-81 cassette drive:- portable, extra batteries available from any shop-
storage cassettes available from shops and thrift stores- no need for linux or
any software skills- user friendly interface, great for beginners- uses
standard cassette drive cable, or alternatively a DIN adapter cable- Large
size, not easily forgotten on the coffee shop table

between a pi and an android phone.. I pick android.
the Pi has some issues
1) it has no safe on/off switch. you can't simply power it down!
2) it is not portable. You will forever be tethered to a power source
3) linux. You have to be linux savvy to use it. period.
4) needs a "non trivial' cable solution.
An android phone however... now that is convenient.
* fundamentally portable
* slick packaging, robust, durable, flexible etc.
* built in connectivity options
* needs a wireless cable (IE BT)
Kurt found a great BT serial module for ~25$
A cheap android phone can be easily obtained...we've only built about a billion
of those in this world.
Anyhow both are neat options. Both work. Both leverage (1) large scale
hardware manufacturing (2) large scale software development projects. Both
require talented people to do the custom work to bring it together as a storage
solution for M100.

As far as I know, the answer is NO. It's not as simple as you hope it would be.
Because you have to realise that the Model T's are, by today's standards,
really primitive computers. There is not even a Disk Operatin System build in.
The only thing that even resembles a DOS, is the communication with a TPDD. But
even if it's dressed up as a disk system, it basically is a communications
protocol over a serial port with another serial device. Actually, not like a
common DOS at all. Integrating a disk - and of variable size - into that means
that you have to translate the commands from the rudimentary communication
protocol of the Model T towards file commands that apply to this disk/ram
device. No simple task if you have to do it all by yourself, i.e., if there is
no underlying OS to wich you can pass commands to. I have the impression that a
lot of people didn't understand what an engineering masterpiece NADSbox is/was.
It translates the TPDD protocol and creates its own disk-access protocol
towards an SD-card, so that this can even be read by other computers.
Basically, he wrote a mini-DOS into a purpose-build computer. There are not
many people in the world who could have done thàt, I think. On top of the
software, there's the hardware. You need to get the signals from a serial port,
through the translating process, towards an SD-card or a flashdrive. Again,
that is not too simple, though there, luckily, you can use industry standard
components. But you still need a skilled engineer - like Ken - to put it all
together with the controller, the interpreting and translating software, to
make a working unit. The NADSbox did all this, custom made. The price was
steep, understandably, but it was still only the cost of the hardware, I don't
think Ken made any profit from it. Basically, to be able to use any modern
storage via a Model T, you need a computer in between to make it work. To avoid
building the computing element from scratch, why not use one off-the-shelf ?
And that's where the Raspberry Pi comes in. This computer is as powerfull as an
iPhone. You have an operating system to handle disk operations, and you have
USB and SD-card ports. The only thing you need now - and that's still easier
said than done - is a link to the serial port of the Model T, and the
translating software. But because you are working in a real computer, the
translating software can be an adaptation of software that already exists. Like
LaddieAlpha. You see that, by using a Pi, you reduce software and hardware
effort considerably. I am working on using an old Pi as a TPDD. Just like with
my DOS station, I intend to write an article and post it to the Wiki. Everyone,
feel free to correct any gibberish I might have mentioned above. |\

Subject: [M100] Could you use a USB portable flash drive as an alternative
device to stores files on a Model 100 ? I was wondering if you could use any
USB Flash drive to save files. Maybe have some software written for it so the
Model 100 would understand it. I heard of the NADSBox and Raspberry Pi. But the
NADSBox is expensive and I am not sure if it is available anymore. As for
Raspberri Pi. It is $35 dollars. I have even seen one for $15. Even a CHEAP one
for $5. But I am not a very technical person or software programmer or hardware
engineer. I am just a basic user and owner of a TRS 80 Model 100. Any
suggestions or opinions that I can get. Duane A. Rejoignez-nous sur Facebook -
