Next, for

plenty of

the

hands -on

construction

details,

check

out

Chediski,

Colcord,

and

Elden's

medium-

budget

project

pages

1245 -1277 of

the same

issue.

It sure

is refreshing

to see

a very

scholarly

journal

that

always

re-

mains simple,

practical,

and yet

quite easily

understood

lay

people.

It looks

the tech-

nology you

should

watching

the quark

-muon

dissociation

and

regeneration

process.

So,

I guess

I was not

too overly

surprised

when

Marcia Swamp

felder

shipped

me her

latest two

peripheral

cards

for the

old

Apple

I Plus, her

MIT-T1

mass-

trans-

ference

transmitter,

along

with her

MTT

-R1 mass -transference

re-

ceiver.

Marcia

tad on

the

con-

servative

side, so

she

insisted on

using

the

illegal

monitor

entry

points

that precludes

the use

those

cards

newer

Apples or

other

personal

computers.

The pricing

is rather

attractive

CARD

$68.50

for the MTT-T1 and a

mere

$43.50 for the separate

MTT R1.

You can order direct

from Marcia.

Anyway, you

first

plug your

transmitter card

into

one

Apple

Plus and as many as

four receiver

cards

into four receiving Apple Il

Plus computers.

Any

object

that

gets placed

the transmitter's

dis-

sociation chamber

then

will

ap-

pear

reconstructed in the re-

ceiver's

regeneration chamber.

The effective

range does de-

pend

on the telephone

line in

use,

but

for your average quality

voice

grade

line,

you can

teleport ob-

jects as

far

as 500

miles using one

receiver, 200 miles using

two re-

ceivers,

100 with three, and 50

miles with four

receivers. The

poorly understood

methodology

of conjugate phase

decongruence

does

prevent you

from reliably

using

more than

four receivers,

re-

gardless

of the distance.

Even on

local

loops.

The

Apple

power

-supply and

baud -rate considerations

both

lim-

it the size of the

teleportation

chambers.

Those chambers

found

on the

MTT-T1 and the

MTT-R1 are

slightly larger than a quarter.

In the

usual demo

of the cards

you

insert

a quarter

into the chamber on

the

MTT-T1 card, and

it will reappear

intact approximately

12 minutes

later

on the

MTT R1.

For a real

"Golly Gee

Mr.

Sci-

ence" demo,

you permit

four

re-

generation

cards to serve each

dissociation

card.

The

single

quarter you placed

the dissocia-

tion chamber

will simultaneously

reappear in all

four

the receiv-

ing

cards,

again

in the twelve

min-

ute

dissociation

-regeneration

in-

terval.

Put another

way, the quad

demo

returns a dollar

change

for

every quarter

that

invested.

Figure 5 shows

you

the MTT-T1

transmitter card.

The teleportation

chamber

optical

fiber coupled

to an

Atascotia

Industries 100-

milli-

watt tunable ultra

-violet

solid -state

laser. I don't

know whether

the

$2.75 price or

the 67-

percent op-

tical

efficiency

is the

most out-

standing

feature

of that

new

component.

The rest of

the card

consists of

RAM,

ROM, CPU,

and

I/O stuff, all

done up

Marcia's

highly conservative

style.

Marcia reports

that

virtually all

her current production

is going

to all the

importers

specialty

herbs and spices.

Her new tele-

portation system eliminates

all of

those

long

delays

at customs, be-

sides allowing her users to

set all

their own international currency

exchange

rates.

New tech literature

new Microelectronic Data

Book just

arrived

today

from Mitel.

It is

chock

full

telecommunica-

tions chips, and

includes bunches

of useful ap-

notes. Two other

re-

cent arrivals

are the Linear Circuits

Applications

from Texas Instru-

ments,

and that

MOS

Products

Catalog, from Gould, who

recently

bought out

AM/ and all the chips

described

in the book.

Some

interesting new strain

gauge

products are

now

available

from BLHElectronics.

In particular,

their

SR -4 should

be useful

for

weighing scales or whatever.

And

Sharp

has a new

LCD

Units

booklet

liquid

-crystal displays and

their

drivers.

Tektronix

has

new TEK Direct

catalog

and several

free video-

tapes out.

Their

oscilloscope

prices

start at under

$700, and

are

much

better

than those of any

other

manufacturer.

Unusual and quite

high -quality

audio

kits are available

from the

Old Colony Sound

Lab.

a caver

who

exclusively uses

carbide

for

light,

I guess I've disqualified

my-

self from commenting

on the ap-

parent stupidity of

still continuing

to use vacuum tubes

in this day

and age. Oh

well.

ColorEase

unusual and

quite

messy

process

that

lets you

create

your own

full color "real

ink" instant transfers that

may be

applied

virtually

any

surface.

Two

interesting new trade jour-

nals

include ID Systems on

bar

codes and such, along

with

Sensors,

for the

robotics crowd.

Turning to

own

products,

you are

at all

into

designing

active

electronic

filters, check out

Active

Filter Cookbook.

If you are

into

high -quality text

or graphics

of any style, be

sure to

look at all

my PostScript stuff, especially

the

PostScript

Show and

Tell. Finally,

remember that

now have fully

updated and

edited Hardware

Hacker bound

reprints available.

Let's hear from you.
