[GreenKeys] data speed tape reader? is it data phone too?

[COURYHOUSE at aol.com]

Great information Jim... What did the dataset look like? When We get one  
piece I  try to find the rest.
Being it has the name DATASPEED does  that  make it a relative  of the  Ink 
Jet Teletype printer?
 
Jim, when did this unit got into  production??

That is  the reader for Dataspeed Type 5.  One of my projects, so I  know
something about it.

Dataspeed type 5 used a 400-series Data Set  (modem) which was parallel- 
wire input.  The transmit modem uses a  very simple circuit, similar to 
that of the TouchTone dial, but with two  transistors generating 9 tones. 
Eight tones for the data bits and one for  timing.  Maximum speed is 750 
wpm.  Because the transmitter is  so simple it is relatively inexpensive
compared with Dataspeed Type  2.  The receiver modem was rather 
expensive, but could either go  directly into a computer or into a Type 5 
receiver that punched  tape.  Because of these cost considerations the 
system was especially  attractive for data collection applications, where 
the computer used an  autodialer to call up a bunch of outlying stations 
using the telephone  network to collect their data.

The Type 5 sending equipment was made in  two forms.  There was a cabinet
form, similar to other Dataspeed  equipment, and also a table-mounted
form which is what you have in the  picture.  For the table-mounted
form the rest of the apparatus was in  a wall box similar to the boxes
used to hold key telephone equipment.   (The prototype had the entire
sender in one desk-top box, but I decided  that did not leave enough
room for a variety of options, so went to the  wall box packaging.)  The
receivers were all in cabinets similar to  other Dataspeed equipment.
The Type 5 receiver used the DRPE punch running  well below its intended
maximum speed, so the problems associated with high  speed operation
didn't show up until later.  I was told that a lot of  senders were
sold, but I don't know if many customers used the receiving  punch or if
they went straight into the  computer.
