[comp.sys.apple] Transwarp II

sysop@pro-generic.cts.COM (Matthew Montano) (11/28/89)

 AE has a new product due to ship in January..
 
 A very clean designed accelerator card that runs at 7mhz, almost no heat, and
is priced at $169US FULL AE LIST! With AE's higher than average reliability,
how long do you think Zip Technoligies is going to last in competition with
this monster from AE?

  It is a full card and I believe sports 9 or so chips, including one 8mhz
65C02.

----break for a commercial----

  Apple's TN regarding serial communications is interesting, they are implying
that making sequential calls reading and writing individual characters to the
modem device at any speed above 2400bps is going to give problems. I can't
remember exactly, but it was mentioned that using string based calls, reading
chunks at a time, that 9600bps communications were possible.

Hmm..

9600bps communications using string writes shouldn't be any different that
character based writes, and it shouldn't matter anyways. (Most Apple // CPU's
can't pump more than 6000bps down the line ANYWAYS). Would reading be the
problem, if the Modem device can't buffer it? I know that since the modem
device doesn't have a no-wait state, that one would have to check for a
character in the buffer everytime before reading, is this overhead enough for
9600bps communications to be hopeless?

Maybe if the modem device had a no-wait state?!
