COMPUTER ON A CHIP

   Intel  has  introduced  an  integrated  CPU  complete with
a 4-bit parallel adder, sixteen 4-bit registers, an accumula-
tor  and  a  push-down  stack  on  one  chip.  It's  one of a
family  of  four  new  ICs  which  comprise  the  MCS-4 micro
computer  system--the  first  system  to  bring the power and
flexibility  of  a  dedicated general-purpose computer at low
cost in as few as two dual in-line packages.
    MSC-4   systems   provide  complete  computing  and  con-
trol  functions  for  test  systems,  data terminals, billing
machines,   measuring   systems,   numeric   control  systems
and process control systems.
    The  heart  of  any  MSC-4  system  is  a  Type 4004 CPU,
which includes  a  set  of  45  instructions.  Adding  one or
more   Type   4001   ROMs   for   program  storage  and  data
tables   gives  a  fully  functioning  micro-programmed  com-
puter.   Add   Type  4002  RAMs  for  read-write  memory  and
Type 4003 registers to expand the output ports.
   Using  no  circuitry  other  than  ICs from this family of
four,  a  system  with  4096  8-bit  bytes of ROM storage and
5120   bits   of  RAM  storage  can  be  created.  For  rapid
turn-around  or  only  a  few  systems,  Intel's erasable and
re-programmable   ROM,   Type   1701,   may   be  substituted
for the Type 4001 mask-programmed ROM.
    MCS-4   systems  interface  easily  with  switches,  key-
boards,  displays,  teletypewriters,  printers,  readers, A-D
converters   and  other  popular  peripherals.   For  further
information,  circle the reader service card 87 or call Intel
at (408) 246-7501.

The age of the affordable computer.

   MITS  announces  the  dawning  of  the  Altair 8800
Computer.  A  lot  of  brain  power  at a price that's
bound  to  create  love  and  understanding.   To  say
nothing of excitement.
   The  Altair  8800  uses a parallel, 8-bit processor
(the  Intel  8080)  with  a 16-bit address.  It has 78
basic  machine  instructions  with  variances over 200
instructions.  It can directly address up to 65K bytes
of  memory  and  it  is fast.   Very fast.  The Altair
8800's basic instruction cycle time is 2 microseconds.
   Combine   this   speed  and  power  with   Altair's
flexibility (it can directly address 256 input and 256
output  devices)   and  you  have  a  computer  that's
competitive with most mini's on the market today.
    The  basic  Altair  8800  Computer   includes  the
CPU,  front  panel  control board,  front panel lights
and  switches,  power  supply  (enough  to  power  any
additional  cards),  and  expander  board  (with  room
for  3 extra cards)  all enclosed in a handsome,  alum-
inum  case.  Up  to  16  cards can be added inside the
main case.
   Options  now  available  include  4K  dynamic  mem-
ory  cards,  1K  static  memory  cards,  parallel  I/O
cards,  three serial I/O cards  (TTL,  R232,  and TTY),
octal  to  binary  computer  terminal,   32  character
alpha-numeric   display   terminal,   ASCII  keyboard,
audio  tape  interface,  4 channel storage scope  (for
testing), and expander cards.
   Options  under  development  include  a floppy disc
system,  CRT  terminal,  line printer,  floating point
processor,   vectored  interrupt   (8  levels),   PROM
programmer,   direct   memory  access  controller  and
much more.
