HINT AND TIPS

From R. VanNieuwenhuirzen: In order to assign your 4023

to device #5 you must go to U4D on the board and pull out pin

#11. This will make the 8023 device 4 and the 4023 device #5.

This will enable you to have both printers on line and direct the

print to either one. <The chip number for setting device

number in the 8023 is U10, and is also a 6532. Opening pin 11

adds one to the device number, pin 12 will add 2, and pin 13

ads 4 (which would put the printer at 8 which is reserved for

disk drives.) See the discussion on device number changes in

the 8050 manual. The schematics all clearly show the above

"pattern matching" pins. >

From Dick Forman: On the 4023 when printing single sheet

the paper out switch is a major irritant. An easy way to defeat

the switch is < I assume also on the 8023 > to insert a scrap of

paper over the switch (located at about 45 degrees above the rear

bottom of the platen roller. Secure it with Scotch tape or even

easier, use a post it note.

From Bob Bushre: A bit more useful fix for paper out:

Install two switches: a SPSP toggle switch in series with one of

the wires going to the paper out switch. Opening the circuit

disables the paper out. A SPSP NO push button across the two

original paper out wires (before your new toggle switch) serves

as a pause control. There is adequate space on the front left

printer panels to install the switches.

From CBUG: A number of members have had difficulty

obtaining parts for the 4023 Printer. The problems are currently

reported as to print head failures (one or more pins sticking) and

were previously reported as stripped gears due to defective

ribbon cartridges. The 4023 was made by Shinwa (see the

mention of the print head manufacturer in the instruction book).

Shinwa USA is located in Morton Grove II., at 5915 Lincoln

Ave., phone 708 470 1600. Two years ago when tracking this

information down, the Shinwa people were most cooperative.

They will sell the replacement heads for a bit over half of what

you would have to pay to a CBM dealer if you can find such a

dealer with parts who knows what a 4023 is!.

CAUTION. Shinwa sells the printer under the identity of

a Compumate CP80. Don’t mention the 4023 or Commodore

to anyone but top management. They never heard of the 4023.

Remember too, these sources are good only for the mechanical

parts, not the circuit boards or chips. For those you have to go

back to CBM or the electronics parts store. Of course, buying

a head as an end user will be without warrantee — but I’m told

there is nearly nothing to installing them. Also remember to get

a 8 pin head if possible rather than a 9 pin head. The 9th pin

will not function as there are no driving electronics in the 4023.

NEVER EVER use a fabric ribbon with the 4023. It may

work for a while, but the ink oils will get into the head and jamb

the head when they dry. Bye bye head.

From Rodney Jay Lillibridge: I think I have found a way to

output the GRAPH characters in Superscript II. Before typing

the desired GRAPH characters type the following command:

*sa7;[Graphic Characters]*sa8

< where the "*" above is the reverse star for Superscript

commands >

<H ere followed a string of graphics which we can not

typeset. > Unfortunately using this method you must have a

RETURN after the graphic characters otherwise you will get a

printer error.

SECONDARY ADDRESSING IN SUPERSCRIPT II

The "Format" instruction in SSII does not work as directed.

In its stead is the following syntax:

To enter the required escape codes, enter at the top of the

document *l=codel, *2=code2, etc. Diablo example above -

*1 = 27. I’ve not experimented with putting more than one code

on a line. NOTE, the * is in fact the REVERSE STAR from

the OFF/RVS key.

Once these codes are preset, you then enter *1*2*3, etc

before and after your text as you turn features on and off in your

printer. The *1 will appear as a 1 in a reverse field, etc. This

capability is limited to 20 defmable characters (lower and upper

case number keys), which is likely the largest quantity needed

to call out any fancy feature set. These codes are necessary when

doing feature work on many printers including Star, Gemini, etc.

You should get both the Centronics manual and the Commodore

interface manual for whatever printers you get as the Centronics

manual usually will not show the CHR$( codes, rather only the

standard escape codes.

I understand SS3 has the format escape codes operational.

From Edwin R. Bowerman: I had a problem with Super

script II when I tried to use the *ch command to create user

defined characters such as superscripts and degree signs.

Superscript *ch command uses an 8 high x 6 wide printer

matrix while the 4023 printer uses and 8 x 8 matrix. The result

is that extra garbage is printed out in the two right most matrix

columns. Precision Software in England came up with a fix.

Brian Leighfield wrote me that *ch could be replaced by *sa5

and the whole 8x8 matrix could be accessed. It works!

Defining a degree sign as *sa5,96,144,144,96,0,0,0,0, and

ESC $ to enter the user defined character, we can write:

the solar home was 72 < degree sign> F when the outside

temperature was 25 < degree sign > F.

A problem will be encountered when two user defined

characters are needed on the same line. My solution is to invoke

the pause command with a status line message to remind me to

backspace the printer of the line feed that the second character

definition creates. This is tricky since the 4023 printer has a

detent mechanism that needs about 9 clicks/line.

Defining a delta as *sa5,2,10,34,130,34,10,2,0 and using a

pause with message (*ps backspace 9 clicks, restart with p) we

can write:

This give a < triangle delta sign > T o f 47 degree sign > F.
