Apple II cassettes by Brutal Deluxe Software
Toinet
Brutal Deluxe Software is proud to introduce the group's Apple II
cassettes to you on http://www.brutal-deluxe.fr/
With a list of around ninety cassettes from different publishers, we
firstly offer scans of the cassettes and their decks. We will then add
audio extracts of each cassette before we create an exhaustive list of
Apple II cassettes around the world. Finding a dedicated space for
such information is another part of the project.
You are welcome to participate in that project by providing us with
your cassette scans and audio extracts.
We wish you a happy near year to you and yours,
Antoine Vignau

What a great archival project! I have a Starcraft tape to contribute
when it arrives at my present location.
All the best for 2010.

an interesting question. What is the minimum audio quality necessary for
successful cassette reads? For computer files, what I mean is, what's the
minimum sample rate, basically? If MP3's will work with the Apple hardware,
what's the minimum bit rate, sample rate, etc?
Thanks.

Right - but nobody can actually prove any of it - it's just a pile of
rumors
and misinformation.
That's right Garber "Hardly " just don't cut it. People need
conclusive
proof without any doubt of what I was accused of - not just sloppy
third
hand gossip. Clearly we both have different concepts on piracy of A2
software. I've done a ton of good things for the needs of the A2
community
--- a lot more good than harm.
Collect your thoughts then carefully reveiw the full contents of;
http://www.apple2.org.za/gswv/me/
I think that link gives the fully
opened and honest me, what I did then and now.
Check out these carefully also and then make your personal judgements
about me and what all I did for the A2 world of a positive and
productive
way.

There is nobody on Earth that can give proof without a reasonable
doubt
that I did any of the bad, bad things that labeled me as the 'Grand
Old A2
Pirate'. Most of you have done some of the very things behind your
little
closed basement doors on your Apple II computers that I've done but, I
don't
see to much of the many efforts to bring old and important Apple II
software
with their src. codes into the public domain or make them available to
others
as abandonware online. In the purely semantic definition of it - sure
I pirated
lots of abandon Apple II software NONE OF IT commercially still sold
and
made it freely open and available thru others who see fit to
distribute it for A2
users to download, have access to and enjoy it -I did that simply to
hoping keep the
Apple II platform alive and self generating with both software and
hardware
projects for the Apple II user to have access to (and it seems to have
worked too).
So hey - call me what you like and then after you review everything I
did and
show opened claim to having done - check the scales to see if it shows
more
good and beneficial actions for the A2 users - than any bad things I
got trashed
over when I sincerely never actually did that stuff that I was branded
and labeled
as having done.
I hope all of you have an enjoyable and rewarding 2010 with the Apple
II platform,
be it in a real Apple II machine or one of the many A2 emulators for
the Mac and PC.
Apple II Forever!

An update to the project:
- the scans are of poor-quality but done
- all cassettes but Apple (ones and several others*) have been
converted to a computerized-form (thanks to Audacity and Ciderpress)
Find the first files here: http://www.brutal-deluxe.fr/projects/cassettes/cassette.po
I am really surprised and pleased to see that the cassettes are in
general good state and can be read easily. Nevertheless, some of them
fail to be recognized by ciderpress after being "audacitized" in mono
at 22 kHz- I use a double-deck cassette player linked to my Hi-Fi
system with a jack ribbon from the jack sound output of the cassette
player to the line input of my MacBook. When ciderpress does not
recognize the WAV file, I use the Dolby noise reductions (B and C) of
the cassette player but that still fails.
Any ideas on other techniques to get them with Audacity and
Ciderpress?

methodologies where computer data are concerned. Computers are so much more
sensitive than humans when it comes to reading data from an audio source. It
might be that the tapes have deteriorated enough that properly reading the
data is impossible. This could be especially true if, while listening to the
audio going into your computer from the tape deck, you hear audio dropouts.
If this is the case, there could well be no way of recovering the data,
short of finding another copy of the same cassette in better shape. One
suggestion, if you have the type of Apple system the software requires, have
you tried hooking a cassette recorder up to the Apple directly and doing a
read the old fashioned way? If the Apple itself can read the data and the
software works fine, but CiderPress can't recognize the wav files, that
would seem to indicate that something's wrong either with your tape deck or
something in your computer setup.
I don't know if you plan to do this, but I think it would be
interesting to have the actual audio files of the cassette tapes. That way,
someone could, at least in theory, hook their computer up to a real Apple
and load the programs in the old fashioned way.

The most likely cause of failure is that the cassettes were recorded
with alignment not matching that of your playback deck.
If you just listen to the cassettes that don't work, do they sound
deficient in high frequencies relative to those that do? If so, then
adjusting your deck's alignment (head gap azimuth relative to tape
motion vector) will probably allow them to be read correctly.
After you are done, you will want to realign the deck with a good
alignment tape, or perhaps with one of the cassette tapes that worked
without adjustment, for an approximate alignment.
The production of cassettes was often a "cottage industry", and
surprisingly often the alignment of the recorder was misadjusted.
Of course, the person recording them never knew, because they
verified them on the same deck!

Embarrassing moment ahead!
In summer band class, 9th grade, we were asked to bring in a song we liked.
I brought "What a Fool Believes", by The Doobie Brothers... (note: no, that
is not the embarrassing part. Well, maybe it is...)
My teacher loaded the cassette in his deck, started it - and out came an
episode of "Kung Fu" that had been recorded years before!
Turns out the azimuth screw had fallen out and the head was all the way up

I keep each cassette as an audacity project file and generate a WAV
file of it (22 kHz, 16-bit mono) which I can upload but I find the
audio file to be too big to upload to brutal-deluxe.fr, zipping the
audio file does not help.
Ciderpress recommends the use of a WAV file of 22 kHz 8-bit mono and
if I find a way to convert to that kind of file, I will upload the WAV
files to brutal-deluxe.fr

Thank you Michael and Jayson for your comments. I have a //e with an
external cassette player which I will use one day but I think the
cassette is probably misaligned or the data corrupt as I hear audio
dropouts. As told by Michael, I will try to align the tape.
Reading it normally or with Dolby B or C fails each time. But if it
fails for 5% of the cassettes and if someone else has them, then it is
no big deal.

Did you try the different analysis modes? Some of them work
better for some types of distortion than others.
(I had a decent set of digitized cassette images, gathered with a
20-year-old "boom box" wired to the sound card's analog input, but they
were part of what I lost when my hard drive ate itself 18 months ago.)

Danged cannibalistic hard drives. 8>O
Bill
Michael J. Mahon
Dropouts can be caused by two things: bad tape (we hope this isn't it)
and bad head-to-tape contact (this is easily fixed).
Cassettes contain a small spring-loaded pressure pad which presses
on the back of the tape to ensure good contact with the head. If this
spring strip is bent or fatigued, there may be imperfect contact--
especially if the tape tension at the head is a bit high.
A good cleaning of the capstan and capstan roller, and the supply reel
clutch (harder) may be necessary. It may be easier to simply substitute
another cassette drive.
The fact is that cassette drives have much lower chances of surviving
in good shape than the cassettes themselves. The O-ring capstan drive
band is a very common problem, since years of unuse cause it to take
a persistent "set", and as it goes around, the capstan speed "wows",
making reading of a data cassette very difficult.
These problems can be aggravated by the supply side tape winding
rubbing against the lubricating sleeves, exerting too much tension
on the tape as it is read. A good practice for old casettes is to
fast forward them fully, then rewind them fully, before attempting
to read them. This loosens the packing of the tape and (usually)
improves the "wind" of the tape on the bobbin.

If the cassettes have been stored in moderate conditions, I'd be
surprised if they cannot be read correctly, given proper conditioning
and deck adjustments.

Actually, I don't think you can (I'd love to be proven wrong!). Audacity
seems to only support 16, 24, and 32 bit waves. In fact, when you open
an 8 bit wave file it automatically converts it into a 16 bit wave file.
I'm sure there are many other wave editors out there that will export to
8 bit however. I know for example that the Nero wave editor does support
exporting 8 bit waves. I have not tried this freeware one, but it also
claims to support 8 bit wave files:
Hope this helps!

Guess I should have done a Google before posting. Apparently you can
export 8 bit waves by following this rather convoluted procedure:
http://n2.nabble.com/Audacity-help-creating-8-bit-WAV-files-td277530.html
Why the audacity developers decided to make this feature so obscure is
beyond me, but at least it is possible.
Sorry for the misinformation. But it is good news for me too, as I have
been wanting Audacity to be able to do this too.

The problem is that the menus of the PC version are not the same on
the Mac, have a look at the main buttons, there are not in the same
order! So, I'll have to dig into the menus :-)

Got it on the Mac version:
- menu File > Export
- select "other uncompressed format"
- click the "options" button
- select WAV / 8-bit unsigned
- That's done
On the PC version:
- Edit > Preferences
- Export > WAV, 8-bit unsigned
- That's it
The PC version is easier to you...

Maybe easy, but not very intuitive. The Mac version sounds more
intuitive - at least it lists the option within the export dialog.
Having to go into application preferences to determine the export format
seems a little dumb to me (maybe its just me though :-) ).

GoldWave puts the option in the Save dialog, but since most users will

reasonable.

The Audio engine for ADTPro does that, after a fashion... it takes
arbitrary data and sends it out as an Apple audio stream. I never
bothered saving it as a WAV file, since they are huge - it's more
efficient to store the raw data plus the engine to decode it. :-)

But, of course, an alignment cassette is only useful to align a

thanks for this great project!
In the Apple newsletter "Best of Contact '78" there is a directory of
Apple software published until the end of 1978 (!) (pp. 24-30), which
consists of more tham 200 titles most of which were published on
cassette! The software is catagorized in the categories education,
financial calculations, data handling, scientific, utility and
entertainment (83 entries alone).
I suppose there are still many discoveries to be made, e.g. I
recenetly asked here for King by Programma and was kindly sent an
interesting adaptation of the original to Applesoft and now with
Antoine's help I discovered that the Programma version is different
from this one!
Furthermore I have a question regarding Bob Bishops "Star War" by
POWERSOFT in Antoines archive. I tried to get this version running,
because for a while now I'm putting together a disk with the various
programs by Bob but I couldn't figure out what to do with the two
resulting machine language programs. Could anybody help me putting
together an appropriate loader?

I was poking at that as well. The first two pieces to it are easy, as
explained cryptically on the cassette label:
4A.FFR (Read in the first chunk of data to zero page)
800.1FFFR (Read in what must be the main program)
I used CiderPress to pull out those hunks of data, and put them on a
disk image. Since DOS is likely fooling around with the zero page
(and Bob liked to make liberal use of ZP as well), I tried loading the
first hunk in to $204a-$20ff, then loaded up the $800 hunk, then moved
the $204a hunk back down to $4f. The $800 entry point just returns
quickly, so I'm not sure if there's a different entry point expected,
or if there's some other behaviors it's depending on. I haven't
bothered reading the code yet. ;-)

Thanks for the reminder, Andy - I have of course read it before, and
promptly forgot about it. :-)
Ok, what's going on with this tape is manipulation of (integer) BASIC
pointers, using memory at the traditional beginning of BASIC space
($800) and that's about it. With an integer machine (or with an
Applesoft machine booted with the 3.3 System Master disk) you can run
the program by:
1) save off the zero page stuff from the .wav
2) save off the $800 stuff from the .wav
3) boot the DOS System Master (or boot your Integer machine)
4) get into Integer BASIC
5) bload the zero page stuff
6) bload the $800 stuff
7) RUN

Thank you Andy,
I have read it a long time ago, forgot the address and put it on
brutal-deluxe.fr in the cassettes section if you don't mind.

Links are always welcome.
I have some decoded cassettes on http://faddensoftware.com/, but don't
have the WAVs anymore. I used DOS Master on the 800K floppies so that
the Integer BASIC stuff would run without having to dance around ProDOS.

tapes thanks to Dirk and my latest purchase. Several tapes from MUSE
and SOFTAPE mainly.
Feel free to visit http://www.brutal-deluxe.fr/projects/cassettes/
We are approaching the number of 200 identified cassettes (not
counting Apple's catalog) and my personal collection is slowly but
surely arriving to 100. In order to finance further purchases, I think
I will sell my 8-bit disks and remaining cards (I know, I know, no US
people will buy them, too expensive :-)
Beep, beep, beeeeeepppppp

I found an orginal cassette of Temple of Apshai / Donjounquest -- do you have
that one? IIRC, someone told me it's (really) rare and valuable.

to get consistent loads of tape data (games) loaded into my diskless
Apple, I found my Nakamichi portable never had a problem, unlike some of
the players at work.
I believe the difference was that the Nakamichi consistently produced
1-volt peak-to-peak output.
The inconsistencies with other tape loaders had more to do with low
output matching into the Apple than any tape-to-head contact (which
certainly does occur, I know). The symptoms of lost bits due to poor
shell construction and too-low voltage can appear identical. It's only
when a crappy cassette is played in a highly reliable machine that the
one masking as the other becomes obvious.
In other words, sometimes it's not an unreadable tape, it's that the
low-voltage tape information coupled with low output voltage _combine_
to fall below a readable threshold.

And, of course, the Apple II cassette input is designed to be driven
by a *speaker* output--so turning up the volume allows you to adjust
the levels the Apple II sees.
