Re: [M100] USB "juice pack"

[Steven Ranft]

I found this on Amazon here in the US. 
http://www.amazon.com/gp/product/B00H01VGTQ?redirect=true_=cm_cr_ryp_prd_ttl_sol_0
It has the same DC to DC converter as the cable John Hogerhuis located in the 
UK.The DC to DC converter boosts the 5V output of the "juice pack" to 6V, which 
is what your Tandy AC adapter outputs.
For only $10 it look like a good deal.
The output plug would need to be changed to suit the M100, but the voltage 
should be fine. 6VDCIf you don't solder, these might work for 
you:http://www.amazon.com/Power-Cable-Female-Connector-Camera/dp/B00EK6OAF6/ref=cm_cd_al_qh_dp_t
 
Unfortunately you would need a meter to be sure how to get the polarity correct 
for the M100.
Obviously, If you can solder and have a meter you can find a plug that would be 
more elegant.

Hi John,
I use a 6v lantern battery in a plastic frame with a power switch and cable 
with the correct barrel connector on it.  I got it while I was living in 
Australia before I moved over to the USA do i don't know what the part number 
is.  I may have even got it at the local tandy store  :-)
Cheers,Bert

Anyone know what it takes to use the phone charger "juice packs" to run a M100?

Is there an off the shelf connector or converter needed or would I
have to build something myself?

I have a handful of vendor swag cheapie units laying around. Running a
Raspberry Pi off one of them.

Thanks!

Actually Steven I think this is the same seller as I saw on Amazon UK. It
seems in the US he just advertises the cables for specific devices instead
of by specification.

I'll write to the seller and see if the exact 6v negative polarity
5.5mm/2.1mm cable can be purchased.

Yes.  Ditto EXACTLY what Ray Lopez said!  With NADSBox and REX, it is all
done for you.

That's a real shame, Ken.  The NADSBox is amazing, and I use it all the
time.

I recently got a REX card from Stephen Adolph and that, in combination with
the NADSbox, make my T102 a truly useful everyday tool.

I think a REX card in combination with the DeskLink TPDD emulator running on
your Windows or Linux computer would be a good solution in lieu of a
NADSBox.

[M100] Is it possible to use USb flash drive with a Model 100

[John Martin]

I would like to have a NADSBox and REX card. But these items are expensive.

I am sure there are cheaper alternatives. If you can buy a Raspberry Pi
ranging from $5 to $35. That is very CHEAP for what it can do.

I believe it would be a great project to take some mass produced hardware
and software and find a way to solve M100 specific problems.  That's true
open source.

I saw that Uber cheap pi. They don't quote power but I believe it is vastly
more than the M100 itself.

It is all tradeoffs!

Re: [M100] Is it possible to use USb flash drive with a Model 100

[Ken Pettit]

Actually, I have an idea that would be REALLY cheap, but it's a software 
effort on the M100 side.  It would be a device that connects the M100 
directly to a USB port on any PC / Linux / Pi, etc.  I would use the 
device below (STM32 which has 5V tolerant I/O) with some tight ISR code 
to interface with the parallel port.  Using this board, it would only 
take a couple of small, simple, dirt cheap interface boards from OSH 
Park (only needs routing and a 26-pin connector to connect to M100 LPT 
port).


http://www.amazon.com/Practical-STM32F103C8T6-Minimum-Development-Arduino/dp/B00OOKAFM0

Then with the right software (on M100, ARM and PC / Pi), when you "plug" 
the Model T into the PC, it simply appears as a Mass Storage Device.  
Simply drag and drop files to / from your M100.

Re: [M100] Is it possible to use USb flash drive with a Model 100

[Ken Pettit]

Hi Lee,

Well, no that isn't exactly wrong.  The 8-bit output port on the M100 
LPT connector is in fact output only.  However it has 2 input bits ... 
the BUSY and /BUSY signals.  With proper 8085 ASM software and proper 
ARM software, a 2-bit "bit-bang" read operation can be performed.  In 
this case, 8 bits are read using 4 successive reads of { BUSY, /BUSY } 
and then re-assembling them into a byte.


This is the way TDock works and I have actually already written and 
tested this approach in VirtualT.  I actually have 3 TDock bare PCBs 
sitting on my desk that I received from OSH Park yesterday, waiting to 
be assembled.  They use a CPLD to perform the signalling and the board 
is a daughter card for the Raspberry Pi 2 B.  But I'm afraid the 
solution isn't really "cheap" because of all the connectors and the size 
of the PCB (building the TDock PCB costs more than the Pi itself because 
of small quantity purchase).  But I believe a fast STM32 ARM chip with 
5V tolerant I/O could keep up with the signalling involved that the CPLD 
is doing.
