.c;HOW TO USE TN20
|
|
.s
|
|
NOTE: Make sure that the cable in the micro-room labelled "TN20" is
|
|
attached to the appropriate port of the micro-computer you are
|
|
transferring to. Follow the instructions for that particular machine to
|
|
prepare it for transfer. When you are instructed to do so, return here
|
|
to run TN20.
|
|
.s
|
|
1. Log onto the DEC-20.
|
|
.s
|
|
2. When the @-prompt appears, type "TN20".
|
|
.s
|
|
3. You will be asked what file to send. If you are not connected to the
|
|
directory that file lives in, you must prefix the file name with the
|
|
directory name, followed by a colon. For example, the Atari and
|
|
Commodore interpreters live in the Z directory; to transfer them you
|
|
would type Z:ZIP.ATR or Z:ZIP.C64, respectively.
|
|
.s
|
|
Most game directories are located on the alternate disk drive, called
|
|
SS. (The primary disk drive is called PS.) In order to copy Starcross,
|
|
for example, you would have to type "SS:<STARCROSS>STARCROSS". TN20
|
|
assumes the ".ZIP" suffix, so you don't need to include it.
|
|
.s
|
|
If you are making a two-disk game, such as Deadline on the Atari, the
|
|
game file must be sent in two parts, called [game].PRE (the first part)
|
|
and [game].PUR (the second part). To split the game file into these two
|
|
sub-files, first connect to the directory it lives in. For example, to
|
|
connect to the Zork I directory, type "CONN SS:<ZORK1>" at the @-prompt.
|
|
When the @-prompt reappears, type "SPLIT [game]". After several seconds,
|
|
you will be informed that the game file has been split. Then, when TN20
|
|
asks which file you want to send, type "[game].PRE", and later
|
|
"[game].PUR".
|
|
.s
|
|
4. TN20 will now ask what machine you are transferring to. Simply type
|
|
the name of the machine: Apple, Atari, Osborne, etc. If you are not sure
|
|
what a valid response here is, type a question mark to get a listing of
|
|
all valid responses.
|
|
.s
|
|
5. TN20 will then inform you of the baud rate it will transfer at (4800
|
|
for the Rainbow, 2400 for the Apple, and so on). Type any key to
|
|
commence with the transfer.
|
|
.s
|
|
6. If everything is okay, a whole lot of A's should begin appearing on
|
|
the screen of the DEC-20 terminal you are using. A's will appear on the
|
|
screens of certain receiving micro-computers, but not all. If the A's do
|
|
not appear on the DEC-20 terminal, go to the troubleshooting section.
|
|
.s
|
|
7. When the transfer is complete, TN20 will tell you the actual baud
|
|
rate and compare it to the theoretical baud rate. (The higher the
|
|
percentage, the better the speed of the receiving micro.) Because of a
|
|
bug, you may get a double @-prompt.
|
|
.s
|
|
8. If you want to transfer another game file, type "RESET TN20". If you
|
|
are done, then log out of the DEC-20.
|
|
.s
|
|
TROUBLESHOOTING: If the transfer didn't work, check to make sure that
|
|
the TN20 cable is properly plugged into the receiving micro. Look at the
|
|
screen of the receiving micro -- there might be an error message of some
|
|
kind there that will tell you what's wrong. Finally, some twit may have
|
|
unplugged the TN20 cable from the other end, in the main computer room.

.c;HOW TO TRANSFER GAMES FROM THE DEC-20 TO THE PDP-11
|
|
.S 2
|
|
1. Log onto the 20. When the @-prompt appears, type "11".
|
|
.s
|
|
2. You will get a prompt that looks like "20>". Type "C" to connect to the
|
|
11.
|
|
.s
|
|
3. Log onto the 11. When the period-prompt appears, type "20".
|
|
.s
|
|
4. You will see a prompt that looks like "11>". Type "R".
|
|
.s
|
|
5. You will be asked for the name of the file to be received. Type in
|
|
"INT:[game]", where [game] is the six-letter abbreviation for the game name.
|
|
For example, to transfer Starcross, you would type "INT:STRCRS". You
|
|
will see a message like "[N blocks]", where N is the number of free
|
|
blocks available in the INT directory.
|
|
.s
|
|
6. The "11>" will reappear. Type "B".
|
|
.s
|
|
7. Hit the BREAK key. The "20>" prompt will reappear.
|
|
.s
|
|
8. Type "X". The @-prompt will reappear.
|
|
.s
|
|
9. Follow the separate instructions for running TN20. When TN20 asks for
|
|
the machine name, type "PDP-11".
|
|
.s
|
|
10. A bunch of A's will appear on the screen. The transfer will take
|
|
around five minutes.
|
|
.s
|
|
11. When the transfer is complete, the @-prompt will reappear. Type "11"
|
|
and hit return.
|
|
.s
|
|
12. The "20>" prompt should reappear. Type "C" to return to the PDP-11.
|
|
.s
|
|
13. When the period-prompt appears, type the name of the game file (DEADLN for
|
|
Deadline, etc.). When the game prompt appears, test the game by typing
|
|
"$verify".
|
|
.s
|
|
12. Leave the game (type "quit"). When the period-prompt appears, log out of
|
|
the 11.
|
|
.s
|
|
13. Hit the break key. The "20>" prompt will appear. Type "Q" to disconnect
|
|
from the 11. You are now back at your original 20 login.
|
|
.s
|
|
NOTE: There are a limited number of remote lines between the 11 and the
|
|
20. If, at some point, you are informed that a given remote line is
|
|
already in use, you will have to try again later when it is free.
|
|
.s
|
|
ANOTHER NOTE: If the INT directory on the 11 is too full, you won't be
|
|
able to transfer the game file successfully. If this happens, ask
|
|
someone to delete some unimportant files from the INT directory.
