Re: [M100] New Age Digital Storage Box (NADSBox)

[Brian White]

Ok, got some numbers.
Conditions:

Main board: Teensy 3.6
Adata 8G class 4 sd card inserted. (different cards draw more or less)
128x64 mono OLED attached by I2C and lit up with a screen of text.
  https://www.velleman.eu/products/view/?id=439232
Serial1 connected to a level-shifter to a pc
  http://schmartboard.com/schmartboard-rs-232-module-710-0001-01/

http://www.analog.com/media/en/technical-documentation/data-sheets/ADM2023_1181A.pdf
The level-shifter is powered from one of the 3.3v pins provided by the
Teensy, ie, NOT from the Vin or VUSB that feeds the Teensy itself. (this is
mostly just to protect the Teensy io pins from getting more than 3.3v from
the level-shifter, but it also means the current draw number
includes the level-shifter)
RTS and CTS lines actually connected to level-shifter too.

USB not connected. Power coming from a plain 5v supply to the Vin pin on
the Teensy, with ammeter in series.

on-board led lighted during sdcard access

Voltage measured at the Teensy and while under load

Running at 2mhz:
While waiting for a keypress: 18.3ma @ 5.07v
While writing to sdcard: 33-38ma @ 5.07v

Running at 24mhz:
While waiting for a keypress: 36ma
While writing to sdcard: 59-66ma

Running at 180mhz (default):
While waiting for a keypress: 96ma @ 4.98v
While writing to sdcard: 96-130ma @ 4.7v

This is with no special tricks to go idle and draw low power. I think there
are lowpower libraries that can do some things, and definitely there are
purely eltronics ways to cut power and restore power based on serial
activity. But my test code right now is just sitting in a loop reading the
serial port.

That's not bad by itself. This is roughly 1/3 of the current draw of
the M102 itself, so maybe ~33% impact on battery life with no
optimization.

I'm pretty sure the serial port can be used to wake from deep sleep,
so the idle current can probably go to single-digit mA or lower
depending on how the SD card handles sleep.

Nice!

Re: [M100] New Age Digital Storage Box (NADSBox)

[Brian White]

24mhz, no OLED attached, totally absent from code too, 5v source, no usb:
Waiting for keypress: 27ma
Writing to serial port at 115200: 32ma
Writing to sdcard: 50ma

This is more like what a tpdd emulator would be. Or less because I think
even the 2mhz is enough for tpdd.
This includes the rs232 level shifter as before.

[M100] Tandy 200 RAM modules

[Josh Malone]

Hi all,

Is there any current source for Tandy 200 24k RAM modules? My T200
only has a single RAM bank. I feel like I used to see these all the
time on eBay, but a search just now turns up nothing.

Thanks,

-Josh

Re: [M100] Tandy 200 RAM modules

I don't know about pre-made, but there is one you can build yourself:
Here's links to the pcb on oshpark and a pre-loaded digikey cart.

There is also a single RAM version with an easier to solder SOIC part.

They do come and go from eBay, just need to look out for them.

Check eBay. There is a gentleman who makes them and sells them on Ebay. I
bought 2 earlier this year and they work great.

Like I said - I know I've seen them on eBay, but I don't see any of
them now. I'm going to investigate the dual-bank PCB option that Steve
posted to OSHPark.

[M100] program library in WAV format

[Jesus R]

Some updates:

I have been testing the save and load function via a Logitech USB to
earphone and microphone interface. This interface came with a gaming
headset. I'm using Audacity to capture and play the file for loading and
saving them on my T100.

As a proof of concept I have some files you can try posted on a temp Google
spreadsheet:
https://docs.google.com/spreadsheets/d/1m7QRN1I5KpJJO_
RKYnwFhmrluDjbYm6bEe_rIgz80ug/edit#gid=0

Setup:
1. Connect the T100's cassette cable to the headphone and microphone jack
of the USB interface. Some computers have these built in.
2. Make sure the volume for the headphone output is 100% and bit perfect.
3. From Basic enter this command which helps with saving the files - sound
off.
4. From Basic enter this command which will clear any pre-existing programs
- new.
5. From the TRS-80 Model 100 manual follow the instruction on page 191 for
Loading a Basic Program from Tape. Here is a link to the manual:
http://www.classiccmp.org/dunfield/kyocera/manual.pdf
Example of filename (caps matter and it must match) - TPL.BA, ZOIDS.BA
6. From Basic enter this command which will confirm you received the code -
LIST
7. Finally, don't forget to save the file to your T100.

Let me know any questions or comments.

Ken, you have been a busy guy:) I didn't realize you were behind the
Virtual-T project. Is it possible to copy and paste code into it? Also,
would a TPDD work with it? If so, it would help me tremendously with my WAV

Re: [M100] New Age Digital Storage Box (NADSBox)

[Ken Pettit]

Hey JR,

Yeah, I began that project back in 2004 from a small (not quite but 
nearly complete) baseline that Stephen Hurd started.  Then I slowly 
added to it bit by bit over the years, along with help from John 
Hogerhuis (Linux support) and Jerome Vernet (MAC and preferences 
save/load support).


You can't copy and paste, but you can use the File -> Load from HD menu 
to load files directly into the emulated file system.  The only thing to 
watch out for is if the extension is .BA, then make sure it really is a 
tokenized BASIC program.  If it is a BASIC ASCII listing, then it should 
have a .DO extension prior to loading.  Then use the BASIC load 
"file.do" and let BASIC tokenize it.


Similarly, you can save Model T files to your host using File -> Save to 
HD.  There are options to save BASIC programs as either tokenized or 
ASCII text.


As for using a real TPDD, this is kind of hit-and miss based on any 
timeouts that the DOS implements.  TS-DOS for instance will time out 
every time if the emulation speed is not set ot 2.4MHz.  And even then 
it times out sometimes.  To use a real TPDD, you have to configure the 
emulated serial port to use a physical port on the host.  Alternately, 
you can use the emulated NADSBox / TPDD server option in the emulated 
serial port dialog.  Then your TPDD disk is simply a directory on the 
host that you specify.
