(beginners and Expert),..

Experiences..

with Commodore,..

Why I love Commodore machines,.

EDITORIAL

First a big thanks to all the people who took time to email

me giving me positive comments and encouragement, I

must say I didn`t expect such a number of emails of praise

to arrive in my inbox! I did receive a few negatives but

they criticized certain layouts of the magazine and

interviews however these users did make suggestions on

ways to improve so I cant call them complaints really as

they were helpful in producing a better more polished

magazine.

because I pay private and they want my custom to

continue, I suppose if they said "you wont recover" then I

would stop paying for treatment.

CP/M

I am making a final push for you guys to supply some

information about Cp/m, I have a little something to put

together for a future issue; but I am a little disappointed

that no one has come forward saying they used, or indeed

still use CP/M with there Commodore machines. Although

many people are still posting messages about CP/M and

Commodore on various news groups and forums. I guess

these users are a little shy so if you feel that way I can

publish your items anonymously if you so wish.

This issue is rather Forth orientated, I was contacted by a

reader with an offer of a tutorial about the programming

language Forth, its quite a long tutorial and the reader

suggested it not be split, but would prefer the tutorial as is

so I hope you enjoy reading about the Forth language, I

also contacted a Forth user group and asked some

questions you may like to read the answers. I have never

come across the language before; it makes some

fascinating reading, if you want to learn more then feel

free to contact me.

Commodore Haters

Its sad that I found out some people are attacking

Commodore users via email and forums criticizing

everything they do or post, Commodore Free magazine

tries to cater for all users as I say every issue from

Beginners who have just acquired a machine through to

Ok I am trying to write a tutorial a game that starts using Commodore graphics and BASIC then extends into using sprites then

adding music and finally finishes with a game in machine code

advanced users. I know the main focus is on the

Commodore 64, but this is a special machine for me as it

holds so many memories. If you have any Commodore

related news feel free to contact me. Back to the haters

then, we are building up a list of user names and I have

successfully traced some users back to ISPs (at cost to

myself) should I publish the information? Well I am

undecided at yet

BASIC to MACHINE CODE

Ok I am trying to write a tutorial a game that starts using

Commodore graphics and BASIC then extends into using

sprites then adding music and finally finishes with a game

in machine code, this will run over a number of issues,

problem is, I am definitely not a programmer and so am

requesting help to write this tutorial, although there are a

number of machine code type tutorials there is little taking

the BASIC programmer with a minimal amount of

knowledge into the real's of assembler or even just BASIC

game design and its pitfalls. If you can help out in anyway

I would appreciate your input, as a reward I can print your

name in the magazine, heck that must be worth

something.

BYTE BACK

As I write this Byte back is imminent and it is sadly

impossible for me to attend due again to the back

problems, you could say the I am "BACK BYTE" Argh

that`s a very poor joke, thanks to everyone who expressed

concerns and although I don`t feel it I am assured the

back is getting better and will "fully recover", or is that just

REVAMP

NOTE: Issue 26 marked the beginning of a new format for the C64 version of Commodore Free:

Use a Mouse in Port #1, a Joystick in Port #2, or Keyboard Cursor keys to navigate the new format.

On the Main Menu screen, you will find a list of Topics on the left, 3 Icons on the right and a Title bar on the bottom.

As you move the 'Arrow' cursor over the Topics/Subtopics or Icons, the Title bar provides a short description of what you can expect when

you select that item.

The top left Icon is a question mark.

If selected, you can read about Commodore Free.

The top right Icon is a music staff If selected, you can play or change background music.

The bottom Icon is a curled arrow. Select this to quit Commodore Free & return to BASIC.

When you select a Topic, you will either get the article or a list of Subtopics to pick from. The article screen displays an article title at the

top, a scrollbar (with single & double arrows) on the right and the words EXIT & PRINT on the bottom. If you click on a single arrow, the

text will scroll one line at a time in the direction of the arrow. Use the double arrow to scroll a page at a time. On the keyboard, the

UP/DOWN cursor key scrolls a single line & the RIGHT/LEFT cursor key scrolls a page at a time.

Select EXIT to return to the Main Menu or PRINT to get a Hardcopy of the article in 80 columns. The keyboard 'E' or 'P' keys also provide

these functions. On the main screen pressing M will toggle the music on or off, but has no effect in the reader application.

DirMaster v2.1/Style

DirMaster is a Windows-based GUI tool useful for the management

of common (and uncommon) emulator formats (such as .d64, .d81,

.t64, .dfi, .g64, etc) as well as native archival formats (such as .arc,

.sda, .lnx, etc).

New in this version:

- t64 *write/modify* support

- t64 "Run In" support

- disk/archive content preview on file open dialog

- remembers window location/size between launches

- cross linked sector check

"Run In" can now operate from a transient disk or tape image; this

creates a temporary image which is passed to the chosen emulator;

temp images are deleted when DirMaster exits

Configurable character replacements for exported file names and

various other user interface tweaks and bug fixes

Jim Brain uIEC/SD Device

- uIEC/SD not only supports SD and SDHC cards, but either SD or

SDHC cards can also be used for updating the firmware (new fea-

ture, older firmware update software only supports SD cards)

From: Jim Brain

I held off on announcing uIEC/SD availability until I had some stock

(impatient folks, you know who you are but I do now have some

stock (90 units).

Pictures available at:

http://www.jbrain.com/vicug/gallery/uIEC/IMG_6514

As with uIEC/CF, units are $50.00/unit, with shipping (for up to 3

units) as follows:

Since uIEC shares the same firmware (kudos to Ingo Korb, who

does not get enough recognition for this fine piece of code) as the

recently announced SD2IEC, I'll spare everyone rehashing the simi-

larities and just note the differences:

$5.00/US

$10.00/Canada

$15.00/Intl

- uIEC/SD is currently the smallest known CBM drive (1.5" x 1.5"

by 0.3"). Perfect for embedding in your favourite machine, drive, or

calculator (shout out to Tone007, who stuffed one in a CBM pocket

calculator)

Email brain@jbrain.com for ordering information, or simply PayPal

the address for immediate purchase.

I'd like to thank all

those who have

purchased uIEC

units. I hope every-

one finds them use-

ful.

Jim

- uIEC/SD shares the same 128kB Atmel AVR 8-bit microcontroller

as the rest of the uIEC line. With 51kB used for firmware, there's

plenty of room left for the future.

- uIEC/SD comes complete for use with IEC connector and power

supply cassette port connector. VIC/64/C128 users can simply plug

the wires in and use. (SX64/+4/C116/C16 users need to source 5V

elsewhere, let me know before purchasing if you'd like an alternate

connector)

- Although not yet defined for use, uIEC/SD offers an additional

switch line and programmatic LED for future use.

Blok copy for the PET

is enabled by default in VICE but is very loud, turn down the vol-

ume before running the game!) If you'd like a version of this game

on tape or disk it should be available soon from Cronosoft for £1.99

(excluding postage and packing).

Trivia: the original and, at the time of writing, incomplete version of

this game was written in order to learn the Atari 2600 hardware

where it utilised vertical splits to achieve eight independently

coloured playfield objects; despite all of that colour, the PET version

is, of course, rendered entirely as green (or orange) on black. The

music is a cover of "End Theme" done on a one channel sound

hack...!

Jason Kelk (TMR) has released Blok Copy, for the Commodore

PET, you will need a minimum of a 40-column screen and 8K of

RAM to run the game. The game also supports sound from the par-

allel port of the PET. To read about it and download a copy head

over to

<http://www.cosine.org.uk/products.php?prod=blok_copy&4mat=ot

her>

The mission objective for Blok Copy is simple; the playfield con-

tains seven distinct designs of tile arranged into columns of five and,

at the start of each level, those tiles are shuffled around; the operator

must then reorganise those tiles to resemble their starting order to

unlock the stage and progress to the next until all ten levels have

been re-synchronised. The controls are W for up, X for down, A for

left and D for right, using these controls alone move the cursors at

the edge of the playfield to select a row and column and holding

down the right hand shift key at the same time will instead cause the

selected row or column to move.

Blok Copy is the first release for Cosine on the Commodore PET. In

order to run it, you'll need a machine with a 40 column display and a

minimum of 8K RAM, any PET that meets these specifications

should be able to run it and those fitted with a parallel port sound

hack will also get titles music, in-game effects and jingles (the sound

New revolutionary C64 music routine unveiled

The routine in question was demo'ed in the production VICIOUS

SID (picture), which also included other crazy audio routines you

can check out by following the attached link.

Commodore Free :- Although this demo was original released on the

29th of October in CSDb

http://noname.c64.org/csdb/release/?id=72678 it's one I missed! Al

Jackson noticed the article on this blog website

http://c64music.blogspot.com/ and I have copied the text below.

Now for the people who still doubt; how about that C64 entering the

charts with minimal external processing effects is getting closer,

wouldn't it be great to see errr hear on a cd :====

Beta testing of this software will start soon, a few artists have started

to experiment with pre-beta versions of the tools, like Fanta, who

made an amazing X'2008 SID music entry with his tune Fanta in

Space, which you can check out by clicking here.

http://oxyron-party.untergrund.net/fanta_in_space.mp3

(this is the output straight from a Commodore 64, nothing added!)

http://c64music.blogspot.com/

A team of super talented coders have managed to break the limits of

C64 sound once again.

The Human Coding Machine from Germany and SounDemoN from

Finland, have managed to create a music routine that allows you to

have:

- 4 channels of 8-bit sample rate, digi playback

- 2 channels of SID synth sound

- You can filter both SID channels AND SAMPLES!

- And you have enough raster time so you are not forced to turn off

the screen, and can actually do something with it ;)

This technique has been presented in the X'2008 demo party, the bi-

annual classic of the C64 scene where usually all barriers are broken

and this one has been, fortunately, no exception!

Ten Ten Duality

The Story:

In a world of bi-location, you must achieve synchronization. "Ten-

ten" comes from the Japanese "dot dot" or Dakuten. Your objective

to align a universe of dots.

web/bulletin/bb/viewtopic.php?t=3362

A game for the Unexpanded Vic 20, Joystick required.

All BASIC.

Game Play:

Use the joystick to control both "Tens" on separate playfields. Take

advantage of asymmetry to bring each simultaneously to its respec-

tive goal. Fail, and your doppelganger will escape to autonomy.

Sleep deprivation does strange things to you. I made this game earli-

er this week between 1am and 5am. I couldn't sleep. It made sense to

me at the time and seemed very fun. The next day, I played it, and I

couldn't understand what the heck I was thinking the previous night!

I decided to just abandon it.

Ok, I know none of that makes much sense, but play it anyway.

http://sleepingelephant.com/denial/games/TenTen.zip

Tonight I am up late again, and the game makes sense to me again.

So, at the moment, my judgment may be clouded. I present to you,

Ten Ten. Whatever that means.
