I confess to being hooked on data-comms from the very first day I ever
tried it. There was something almost mystical about actually getting
computers talking to each-other. Indeed many people who make their
living from others ignorance often do their best to perpetuate the
myth, and make data-comms look more like a black art than a method of
communications.
Of course it has it's pitfalls, but too many people feel threatened by
all the jargon and new kit needed to communicate. Over the years,
Compulink has always had some sort of on-line database for its members.
We feel our experience in this field is matched by very few in the UK,
possibly the world.
One of the most difficult things in setting off up the path to data
comms, is choosing a modem. The modem is the 'black box' that actually
translates the computers data into a stream of sound that can be
transmitted over the telephone, and can be understood by the modem at
the other end of the telephone line.
Compulink has stood solidly behind the Miracle Technology WS4000 for
about 9 months now as being the best modem under 200 pounds. The
WS4000 offers pretty much unrivalled price/performance. It will work
at 300/300 baud (characters per second) and 1200/75 - The latter is the
more difficult of the two speeds to acheive on an IBM-PC or clone, as
the PC will not actually operate at split speeds. ie 1200/75. The
WS4000 was designed to get around this problem, and it does the job
admirably.
Now you've got your modem - what are you going to do with it? If you
are using your PC in a corporate environment, then you will have
probably been told already what the modem is to be used for. If you
have no corporate fairy-godmother to guide you, then unless you have
previously gotten friendly with the local hacker community, you're on
your own. It's a catch 22 situation - you want to communicate, but
don't know how to. If you could only get this thing to talk to another
computer then all your troubles wil be over.
One of the main reasons we are so keen to get you on-line is to
show-off CIX - the Compulink Information eXchange. We have been
talking about this for so long, it seems hardly worth going over old
ground, but there may be a few that haven't heard about our plans, so
this next bit is just for you....
Ever since I started the first Compulink bulletin board, I was faced
with a problem. I had just one phone line into the computer, I used
the same line for outgoing calls too, but I soon got tired of this and
got another phone line fitted.
It's a funny thing running a bulletin board, when the board is quiet,
ie. no-one is using it, you sit there waiting for a call. Then as
soon as you get a call, you feel almost cheated because there might be
someone else trying to get into your number, but can't. On a PC this
is normally something you have to live with. The PC is a single-user
machine - only one person can use it at the same time.
It was a real revelation to find out that there was a piece of software
out there that would enable me to run the bulletin board at the same
time as I was using it. The trouble was it costed 500 dollars, and was
only available in the USA. Luckily I came across another program
called MULTIJOB which appeared to do the same sort of thing. True
enough it worked ! After carefiully installing MJ I now had two
computers.
It wasn't quite as simple as that, and there were still some things to
look out for as the whole thing would suddenly lock up for no apparent
reason. Now I had two computers, I could do something really clever
and run the bulletin board as a background task. Amazingly enough it
worked, what a buzz, I could use the computer at the same time as
someone else. I now had a multi-user machine, but only one person
could use the bulletin board at the same time. I had another telephone
line, and if I could make MJ work with two partitions maybe I could
make it work with three partitions and run another bulletin board on
the my other telephone line. This I did, and two years ago I was
running the first multi-user BBS in England, and one of the few
multi-user BBS's in the world.
The BBS got very busy on occasions, and I had lots of complaints from
members not being able to get into the BBS for days at a time. In
November 1985 Compulink was getting a bit too much to handle as well as
a full time day-job, so I quit to work on the user group full time. We
had already turned over one of our bedrooms to Compulink, but it was
gradually overflowing into all the other rooms in the house. So I
started looking around for an office. We located one in Guildford,
just 150 square feet, but at least it got Compulink out of our house.
It also gave us room for expansion as it wasn't possible to fit any
more telephone lines into our house.
I didn't want to be put in the same situation again with callers
wanting to get through but getting an engaged signal. So we installed
SIX data-lines. It looked like we would have had enough lines. We
didn't really expect more than six lines to be busy at the same time.
As usual - we were wrong, luckily it took about six months for the
system to pickup to full capacity, and it was only in late 86 that we
started getting all six lines busy on a regular basis. By this time we
had experienced some hardware failures, and all was not rosy in the
Compulink camp. We had to decide if it was worth spending more time
and money on our AT based system, or to go for something that was more
up to the job.
By this time FIDO was hosted on a complicated 'pseudo-network'
comprising a Compaq Deskpro 286, a Sperry IT (kindly loaned from Sperry
UK after the demise of the aforementioned AT), and another AT clone. I
refer to a 'pseudo-network' because that's how it must have appeared to
our users.
We were using the MULTILINK and LANLINK software packages from the
Software Link - distributed in the UK by ICCT of London. Multilink
allows the host AT to multi-task, and LANLINK is a local area network
that operates over RS232 cables. Both ML and LL worked well enough in
a simple network, but our system required not only that all three
machines to be multi-tasking, but that they be networked too. Each
machine was running up to five 'tasks', apart from the obvious speed
problem, the main problem we had was interupt clashes. There simply
aren't enough spare interupts in the AT's to cope with such a demanding
network. The AT and PC range of computers can only communicate using
COM1 or COM2, in other words you have to do some clever tricks to make
the AT address nore than the standard two comms ports.
The answer was to use a computer more suited to multi-tasking than the
IBM-PC based machines. This is where a number of ideas merged into one
and the resultant system was CIX. We had been talking to Byte Magazine
about their BIX system for about a year by this time (November 86) and
had made a few useful contacts. The BIX/CIX software as written
originally by the University of Guelph in Ontario Canada. Guelph's
system is called 'COSY' an acronym for COnferencing SYstem. We read
the reviews of BIX and decided that CoSy was the system for Compulink.
All we had to do now was select a computer to host CIX - and of course
finance the purchase. We sent out several mailshots to the membership
with cut-price offers, and eventually raised the 15,000 pounds needed
to put a deposit on the hardware, and pay for the software.
The machine arrived in late November, and I went over to Canada to buy
the CoSy software in early January. Within a week we had CIX up and
running in beta test. There were a few problems, and we had to do an
extensive re-write of some of the CoSy modules.
As it stands right now, it costs us in the region of 5000 pounds a
month to provide the CIX service. Compulink cannot afford to absorb
the cost of running CIX as we had previously done with the FIDO system
so we decided to make a charge for the service. It wasn't an easy
decision, but it was the only way that we could afford to pay the
lease. Predictably our newly announced charging policy was greeted
with mixed reactions. Some users simply refused to use the system and
accused Compulink of a 'sellout'. There was a very heated conference
about the whole issue of charging, and another about the user agreement
that we 'borrowed' from BIX. The conference (cixadmin/billing) is
still going strong.
Then a strange thing happened. The users that were complaining
realised that the system they were complaining about was actually a
versatile and useful tool - now many of them are CIX addicts.
There are already over 30 conferences on-line, most of which have been
started by members and subscribers. There is one group co-writing a
multi-user game in one of the conferences, and we already have a good
spread of 'non-computer' topics, such as 'property', 'books' and
'films'. And they're growing all the time.
I'd like you all to know that we had your best intentions in mind when
we set CIX up, and I'm sorry that we have to make a charge for the
service. There's simply no other way we could get CIX on-line.
I truly believe that the small cost is worthwhile - if you were to use
the similar BIX service you would be looking at between 20 and fifty
times the cost of our system.
Many members have never used any of our on-line services. I don't know
why this is, perhaps it's because they don't own a modem. We have
endorsed and sold the WS4000 modem for close to a year, and have
observed a gradual increase in the number of members on-line. We feel
that any member who is not using a modem is missing out on wonderful
new phenomena. CIX was recently described by Ralph Bancroft - features
editor of PC Business World as "electrifying"
You can find the full review in this Magazette under the heading
"Review of CIX" - judge for yourself what an independant third party is
saying about CIX. Ask yourself if you're not missing something
important.
If the answer is YES, then we have a special offer to those of you
wanting to use CIX, but are presently without a modem. We have put
together another one of our very special members-only offers.
I'm sure you are all familiar with the COMMUNIKIT, well now we've gone
one better, the COMMUNIKIT PLUS. The COMMUNIKIT PLUS comprises :-
1) A miracle Technology WS 4000 modem
2) A copy of PROCOMM - the best user supported comms program.
3) A cable to connect your modem to your PC.
4) A quickstart communications guide - how to get your modem online to
CIX within 5 minutes.
*5* Registration on CIX.
*6* A CIX user manual (70 pages)
*7* A CIX quick reference guide.
*8* Your first month on CIX is free.
** 159.95 ** 159.95 ** 159.95 ** 159.95 ** 159.95 ** 159.95 ** 159.95 *
Subsequent months are billed at the minimum monthly for online time not
exceeding 5 pounds.
Considering the recent price WS4000 price increases, the COMMUNIKIT
PLUS must be the best value in England. If you would like to take
advantage of this special offer fill in the CIX registration form and
write on the bottom COMMUNIKIT PLUS offer. The price of the COMMUNIKIT
PLUS is just 159.95 pounds plus VAT.
Of course if you already have a modem - you can still use the CIX
registration form just to register for CIX.
