i just bought an atari assembler/editor from a mail order company.
however, i found no doc with it and a cheap plastic bag with a hand
written label stated it's atari assembler/editor.
they have a price list with the package which stated that the manual is
$9.00 . i'm wondering if atari editor/assembler comes with a manual.
anyways, i will order another package from another company which i'm 
sure that they will include a manual.
it needs time to wait for a new package to come, i request if anybody
here in the netland can me a command to active the cartridge. at least
i should know if this one is work or not, and i plan to make this as
a back-up. unlike most atari game cartridge, it has no display when i
powered on my machine.
and a advise to some atari fans, be careful to read the ads before you
want to buy something from mail order.
i also found ICD PR:CONNECTION is fine so far for the serial/modem
port (R1:) with my modem, it is working fine with most atari 850
terminal program. they include the public domain programs too.
finally, i want if anybody knows a good atari user group where i can
buy more public domain disk. i'm tired to download from compuserve,
and the expense is high too.
thanks in advance for your help.
