4023 HARDW ARE ERRORS by A la n B o u v ie r

Don’t despair when you

turn on your printer and it just

flashes at you like an idiot.

It’s talking to you. It’s trying

to tell you what is wrong.

When you turn on the

printer it first does some in

ternal checking of some of it’s

chips. If it finds something

wrong it flashes at you to let

you, or the repairman know

what’s wrong. Each error has

a number. To indicate a 1, it

flashes once and then pauses,

flashes once and pauses. For

a 2, it flashs twice and pauses.

The list of error codes of

the 4023 and the chips caus

ing them are as follows:

Error Desc.Chip ID Chip#

1 -zero page

2-Rom chksm

3-Timersl&2

4-Timer 3

5-Timer 4

Generally, replacing the

chip which is generating the

error should cure the prob

lem. There is always the

chance that the problem will

still be there after replacing

the chip. If that is the case it

is time to take the printer to

your local Commodore serv

ice center and let them know

what was done. (Save them

the same efforts.) It would be

a good idea to keep a copy of

this list in the printer manual

just in case you one day find

that your printer has died.

Even if you don’t do the

repairs yourself, it may save

you some money. I don’t know

how many service men actu

ally know of this or just re

place the whole thing. All of

this was obtained from the

disassembly of the 4023 oper

ating system. I would think

that the error meanings are

the same for the 8023 but the

chip ID’s would probably be

different.

It is possible that if timer

1 is not working, it will hang

the printer. It will sit there

without any lights coming on.

(see below) To check to see if

this is the case, turn the

printer off, remove chip U4D,

and turn it back on. If it does

not indicate error one, then

THE CASE OF THE CONFUSED

4023 CHARACTERS By: Warren D. Swan

This article will present a

simplified approach to the

characters thought to be un

printable using Superscript II.

These are the left bracket, the

backslash, the right bracket,

the up arrow, and the left ar

row. The Commodore dot

matrix printers have always

had a bug in their character

generation ROMs that cause

these charac ters to be

switched with some graphic

characters when they are

printed in the upper/lower

case mode. The characters

were never lost, they were just

confused.

One section of this article

explains the exact problem.

Another section describes a

utility for printing non-Super-

script II files to a Commodore

dot matrix printer so that the

above characters get printed

correctly. Before that I will

describe a trick that allows us

to get to these characters us

ing Superscript II without a

lot of work, or changing ta

bles, or patching in machine

language routines.

Please note that if you are

writing a document that will

normally be printed by both

letter quality and dot matrix

printers, you should probably

avoid using any of the above

characters but the left and

right bracket. Why? Be

cause the letter quality print

ers usually print characters

that might not have been ex

pected or desired.

The reason being that the

character codes used by the

Commodore computers and

dot matrix printers are based

on (a mutilated version of) the

1964 American Standard

Code for Information Inter

change (ASCII) character set,

whereas all of the letter qual

ity printers use the 1971 AS

CII character set. The later

character set replaced the up

arrow with a "hat" (also

called "circum flex" or

"carat"), and the left arrow

with an underscore. Also,

each letter quality printer (or

print wheel or thimble) maker

seems to have a different idea

as to what to replace the back

slash with.

For that reason, in this

article I have chosen to write

out the words (like up arrow)

instead of using the actual

symbol, since I don’t know

what would be printed when

my article gets published!

Also, since the published ar

ticle will not be able to use

reversed characters, such as

the reversed * that Superscript

II displays when RVS is

pressed, I will underline all

characters that are to look re

versed on your screen when

using Superscript.

THE PROGRAMMING

TRICK:

We will use a little known

and lesser understood feature

of Superscript known as the

"format =" command. Yes, it

does work on all versions of

Superscript, but none of us

knew how to use it for the

longest time. The purpose of

this command is to send spe-
