My psion 3a's microphone is broken. How an I fix it?
While I am in the case, is there a modification that Psion can
recommend that gives me headphone out and microphone in, as I feel
that the Psion 3a rather lacks these.
Pulling .wve's off a remote PC does not work real time, and a 4 min
techno track as a .wve takes up the whole Psion 3a! A mod file player
would be nicer, but I am stuck at the moment on getting 4 tracks of
amiga sample audio through one channel. Its not impossible. I would
do some work on wavmod (the mod stands for modify not
Sound/Pro/Tracker module which is very nice, but samples is not
enough, expecially as I have broken the microphone and so cannot
sample. Idiot I am with a sharp instrument.
What is needed is an analog synth with digital filters. I am going to
look into porting sapphire<sp> to the Psion 3a from Unix. This renders
a digital filter pipeline into a .wav.
I have been doing lots of FFT frequency plots on 'mxv' on linux of all
my favourite acidcore tracks. I think the noise I like, the 303 noise,
gives the following time/frequency plot:
f/Khz
0 3 6 Event/Sequence/cubase
+---------------+
0| \=\ | ---- portamento up noise
| \=\ |
1| |=| | ---- end portamento
t/s | |=| |
2| /=/ | ---- portamento down noise
| /=/ |
3+---------------+
Any ideas/clues for a hopeless acidcore fiend?
Kids love Psion 3a's. The keyboards are just perfect size!
I have been copying each Psion 3a 2M file system incarnation into my
home directory. Anyone interested in having these on the net
somewhere as a sort of online running 'Nick's Psion cache directory'
sort of thing. So far I have:
Sound development:
Piano - Cheesy beepy piano thing
musipoc - Cheesy two voice melody thing
wvemod - Sample editor, like Protracker on Amiga or mxv on Linux
Very very nice.
lots of fun samples
sapphire - When compiled up with smallc, hardcore non-realtime
digital signal processing and synthesis.
Sound Potential:
bab.wve - 1.7MB of babdobelin.mod from aminet mods techn, wicked,
loud and digital all the way down to the Psion 3a speaker
Kiddies games (keeps them quiet!): Only beaten by gamelan.
bunnies - Clone of original ZX Spectrum Platform & levels
tank - 3d tank duel, seriously good 3d like elite
stigma - quite state of the art arcade game
tron - two player, amazing fun
Program development (just dreaming)
Small C - Nice.
revtrans - to reverse engineer others OPL and rip bits out
docs - from Psionics, system calls
assembler
disassebler
Small C decompiler - using j2c from java as template.
macro processors
shells
window managers
tighter RPC - IPC - TCP/IP - NFS - device binding with Linux Box/Internet
Entire GNU/Linux command set and window managers
My current theory is that the 2M of Psion RAM is just the local cache
of all the packages I have on the Linux box, and hence the Internet.
RCOM is very very nice the way you can access ALL Psion drives on PC
and, best of all, all PC drives from the Psion using REM:: . That
wasn't expained very well. Now what I want is to be able to reach
whole Linux file system from Psion. Then I can NFS link
sunsite.doc.ic.ac.uk to the Linux box, and hence to the Psion, and get
files off the Internet into the Psion FROM THE PSION something like:
REM::/mnt/sunsite/pub/psion/devel/*
or
cp /mnt/sunsite/pub/psion/devel/* /psion/mnt/LOC::M
Wow, that would be sexy. Getting closer to Java all the time.
Anyway, any sign of the TCP/IP stack? Unix compatible C compiler?
Terminal program? Modfile player?
Insidentaly, the reason freeVT sucks is that is doesn't have
Xmodem/Ymodem support. Upon reading the manual in Psionics it says
that Xmodem/Ymodem is built into the EPOC OS as layers on a device
driver, so it shouldn't take much to get it working. Sort it out, eh?
Why has nobody given me a copy of the SDK yet, warez style? Go on, I
can't afford to buy it, not on 35 pounds a week Giro (the Psion was a
gift) and the newsgroup is full of people just begging those with the
compiler to 'O please compile up something you powerful rich people
with the means of production.' You might even get some java/Psion
crossover ported stuff.
Come on Psion INC/PLC/Mega Corp, you are inhibiting the development of
the Psion with your petty profiteering. I will get a copy of the C
compiler one off someone else, anyway, but it would be a nice gesture
on your part. ? How many copies have you sold? Give it and info away
for free or Linux / GNU / Sun / Java / The-Whole-Damn-Internet will
laugh and leave you behind, despite the best efforts of all these nice
folks.
Do you even read your own newsgroup?
Yours Nick Macro

Probably. Buy an electronic engineering book, study, and then when you feel competent enough, go for it. > What is needed is an analog synth with digital filters. I am going to > look into porting sapphire<sp> to the Psion 3a from Unix. This renders > a digital filter pipeline into a .wav. Er... I think you are taking this sound thing *far* too seriously. The Psion plays essentially 8-bit sound, through a speaker which is designed to support beeps. You can get a feel for the limitations of the frequency envelope by writing a program which BEEPs through all frequencies (starting higher gives a better idea, IMO). Loud sounds lose a great deal of resolution because of the encoding algorithm. There is *no bass*. Add to this that the Psion is no powerstation, and you simply don't have a good basis for a music workhorse. Still, each to his own. > Any ideas/clues for a hopeless acidcore fiend? I'm tempted to say "Get real.", but you seem to have admirable conviction, so I'll instead say "Yeah- go for it- I'll believe it when I see it.". I sincerely wish you all the luck in doing whatever music manipulation stuff you do- be sure to tell us all about it here, won't you? > I have been copying each Psion 3a 2M file system incarnation into my > home directory.

That way, anyone even remotely interested in what you do can take a look for themselves. [scads of stuff removed] That was weird. You have an NFS server and a dissassembler for the Psion? > My current theory is that the 2M of Psion RAM is just the local cache > of all the packages I have on the Linux box, and hence the Internet.

Modfile player? What's a unix compatible C compiler? Otherwise, yes (probably), yes, yes, and no.

Why don't *you* sort it out if it sucks so badly? Or presumably you believe the rest of the Psion community is at your beck and call? > Why has nobody given me a copy of the SDK yet, warez style?

You might even get some java/Psion > crossover ported stuff. The newsgroup is also full of people that recognise that piracy kills platforms. I notice that you've crossposted this to an amiga newsgroup too, a platform blessed with having plenty of pirates. We (Psion users) are blessed that there quite literally a massive number of "great guys (and gals)" who will utterly bust a gut to help people out. I've personally had far more help from Ali Manson and his terrific support team than I deserve, the folks on CIS are superstars when it comes to answering any question from the simplest to the most complicated, and the contributors to comp.sys.psion graciously wade through mountains of crap (sorry- read "usenet") in order to expound their knowledge and help others. Why not use them, instead of stealing? By the way- openly soliciting for illegal stuff is asking for trouble. I assume you knew that, but were having a momentary abberation. But hey- if we break the law by giving you free software, we "may even get some java/Psion crossover ported stuff". I'd like to see you run some Java on the Psion- I really would. > Come on Psion INC/PLC/Mega Corp, you are inhibiting the development of > the Psion with your petty profiteering.

You just told Psion that you don't care about them enough to steal from them, and now you're asking for free stuff. Cosmic. Your turn of phrase is par excellence. I *do* hope Psion get in touch with you. > Do you even read your own newsgroup? What do you mean? Psion doesn't have a newsgroup.

To be honest, I rarely give messages wherin the poster advocates software piracy and wants something for nothing, much consideration. All the best Ali
