 Today I want to tell you about the development
boot of the famous Novosibirsk group
FLASH Inc., bearing the proud name VICOMM 2.
As you probably already guessed, the speech will
details about the modem for the ZX-Spectrum.
  In preparing the article, we used mathematics
rials of the demo programVICOMM 2
FLASH Inc. group, for which I want to thank
to express my deep gratitude to them.
  Well, now closer to the body..., that is, to
business.
  Radioelements that you will
get it before you start assembling
of this device are given in electrical

  Хочу обратить внимание на то, что  модем
будет устойчиво работать в том случае, ес-
ли у вас правильно  отрегулирован магнито-
фонный компаратор. Проверить его можно ос-
циллографом, сравнивая положительные и от-
рицательные площадки на осциллограмме.
  Подключается VICOMM 2to the computer
as follows: Input - to TAPE OUT , Output -
k TAPE IN .
 To work with the modem, use the following:
Operating software:
  This is, firstly, the MODEM 3.6 program, which
noraya allows you to work at speeds of 600
and 1800baud, but the most convenient to use and
the fastest (2400 baud!) is
MACRO MODEM program.
 That's all. Any questions, call...
