PCMs

PCMs

Years ago I designed a PCM, this was around 1970 maybe. PCM stands for

Parameter Control Module; the idea was to create a unit which could

connect and control other similar units. PCMs were digital but they didn't

need to be. There were any number of inputs and outputs. The idea was that

anything could be connected to anything else. In other words, there were

standardized simple protocols in terms of voltage and bandwidth; every-

thing functioned like blood in the veins of some untoward ganglion. In

order to enter the PCM array, translation was necessary from an outside

world into the protocols; this was the job of an input interface which

could be tailored for particular situations. The interface was divided

into two sections: the outer section was tailored to the world, and the

inner, to the emission of protocols. So the input interface was generous

in its acceptance. At the other end of the array, there was a similar

output interface, divided into two sections; the inner section was

tailored to the protocols, sending the signal current to the outer

section, which was tailored to the world, and generous. For example, an

audio input interface might take microphone signals and standardize them,

sending them to the array; an audio output interface might take the array

protocols and send them simultaneously to audio amplifiers and a lighting

board. What made the array of greater interest, of course, is that input

and output signals could also be applied directly to any particular PCM,

bypassing the standard interfaces. The array as a whole, as a ganglion,

would be in effect a ganglion open to the world at any place or space,

both for input and output. One might think of the PCMs as formal neurons.

Internally, the components of the PCMs might be smoothly voltage-control-

led, with the possibility of directly inputting different equations; one

might begin with standard smooth trigonometric functions and replace them

with discontinuities of all sorts, including chaotic behavior. I believe

to this day that designing the PCMs would have been a relatively trivial

matter. Although the project remained stillborn, the concept behind it

remains of interest to me. I've begun to think of the arrays, inputs and

outputs, as an affair in which anything might modify or influence any-

thing, including, reflexively, itself. The arrays in fact might be virtual

and one thinks only of empty, undefined, space or air, a distant model of

the real and external world, where such things happen. Thus anything here

and now has the potential for affecting anything else, and anything might

seem to turn around and talk directly with you, listening, at the same

time, to your innermost thoughts, whatever you choose to reveal: here are

the input and output interfaces. What goes on in such virtual arrays is

only the ideality of the world itself, the ability to take-for-granted

that there are always relatively stable domains for communication or

dwelling, for work or discourse, and so forth. Any dynamic action, any

action which changes in time, might be considered to be modeled thus; any

static action might be one which leaves the virtual array quiescent. The

size and power of the virtual PCMs are also of interest; as they decrease,

one might argue that the granularity of the world is increasingly differ-

entiated, just as their increase transforms the granularity into rougher

constructs handled by integration. In the middle lies everyday life, where

processing of this sort is kept to a minimum. I can imagine in this

fashion thinking of the world as a vast complex of fundamental operations

on the ordering of everyday life, just as Aristotelian logic and its laws

of distribution appear to deal well with the uncanny lack of transience of

everyday objects. The edges of such modeling, however, are always limit-

points which a different kind of roughness appears, for example quantum

phenomena or color vision or even corrosion. To some extent, these rough

processes, including unknown one, can be imagined within the virtual array

which would have additional signals, alarm signals, that anomalies were

working their way into or out of the array; there could be, in fact,

virtual interfaces utterly open to the real, whose sole purpose would be

the conversion of such anomalies. One process would be that of the name,

beginning with the proper name, and working towards untoward generaliza-

tions; another would be that of radical smoothing, and a third might be

the cessation of array activity altogether. I think of this as burrowing

or death, depending on the degree of destruction or rearrangement

encountered. Likewise, there would be inverse processes, those of birth or

emerging, in which partial identity transformations would remain and

perhaps even be backwards-traceable, backwards-compatible in terms of the

protocols. The whole, virtual and real, is a form of metaphor ready to be

implemented. I can only conclude that the same is already in the world,

and perhaps always already in the world, it is there and here, it is

operational or quiescent as you like. And such would be the world and its

dynamics; it is only a question of looking over your shoulder, back into

the space you have just left behind, forward into the space your are about

to enter. If you have the time, of course, without catastrophe or

disruption.
