The cassette pretty much simulates the paper tape of the old ASR-33

The write mode on the cassette is is either "continuous" or "record",
if it
is continuous the tape writes characters in blocks on 'n' characters, if it
is in "record" mode it writes a block that ends with <CR> (carraige
return). I'm trying to see if I can hack in the reader-run control from the
M8655 (300 baud). If so it should be possible to copy my set of PDP-8 tapes
to cassette and then load them from the terminal. (Weird but cool)

Talking of Silent 700s, has anyone else come across the
'ASR' version? I
have one with an extra box on top with 2 digital cassette drives on the
front and a panel of switches and LEDs. Inside said box there's a little
cardcage with half a dozen cards packed with TTL in it.
Yup, I've got one sitting in the office across the hall.
From the
markings on the switches it appears you can type to cassette,
print out the text on
a cassette, copy characters from one cassette to
the other (and I guess type extra ones from the keyboard), send text from
a cassette to the line, record characters from the line on a cassette, etc.
I've not got it working (yet), but it's on the 'to be hacked' pile...
