[GreenKeys] newbee AGAIN RE: HAL ST800a

[Jeffrey Angus]

The ST-8000 has a CRT display for tuning, LED dispays for the shift and baud 
rates,
and rotoary and toggle switches on the front panel. The ST-8000A has a 
membrane
keypad on the front paney and bar type LEDS for the tuning indicator instead 
of a
CRT.

Both are designed to handle a 60 mA local loop for a real teletype machine.

Subject: [GreenKeys] newbee AGAIN RE: HAL ST800a

> I posted a question earlier today about HAL modem ST800a, to which someone 
else added an additional question.  While their added-on question got 
response, my question seems to have "fallen through the cracks."  I had 
asked about the Hal modem(s) on ebay and their application/compatability to 
running the old 15s,19s, & 28's including supplying loop power and ability 
to adjust to the 60ma requirements and the possibility of the unit running 
multiple machines simultaneously. What I see tells me this is exactly the 
application (plus much more) this unit was built for.  However, my 
knowledge is SO lacking that information from experienced/knowledgable 
sources would be welcomed. 
> Also the other poster asked about difference(s) between the ST800 and 
ST800a.  I have not seen any response to that, although since I get the 
digest version it may come later.  THANK YOU!
