PedroM 68k OS Released
Posted by Michael on 10 December 2003, 23:21 GMT

Patrick Pelissier, author of PreOS and other fine 68k programs, has written the first third-party operating system for the 68k calcs. The open-source PedroM looks like a Unix shell, has task switching and a much smaller size (only 192 KB). It is designed to be compatible with the AMS 1.xx series.

In order to include this OS in our archives, we have added categories for TI-89 Operating Systems, TI-92 Plus Operating Systems, and Voyage 200 Operating Systems.

Morgan has also been fixing up the TI-83 Plus Flash directory into subcategories of games, science, math, et cetera. New submissions should no longer go into the general Flash category but rather one of these new subcategories.

Update (Michael): We are currently being Slashdotted, but holding up just fine because HTTP requests are load-balanced among our Beowulf cluster of 2000 TI-85s. Bring it on!

Basic programs don't work - only assembly ones.

Every ASM program I've tried so far has worked. TICT Explorer, eBook reader, Phoenix, Space Dementia...

Try with Hw1 programs, anyway there is a list of compatible programs inside one of the docs included with PedroM

Which programs do you try ?

off(), recompiled for AMS 1.00, my tsr_list (autoclbr(), isl()), and some other things which I forget. I'll look at a V200 text file on my PC's most recent backup once my V200 is repaired or replaced, which could take some time :(.

OK, I looked at the file and that's it, except for ID, which obviously won't work and I didn't try. I'll try some other ones (the ones mentioned above).

How the devil do you SEND a .TIB file to a real calculator? I've done it before but have since lost the Windows program to do so. Someone help me out - all I've gotten so far are people who say "use the TIB receiver" - which is a no-brainer.

Open tib and a 89u file in a hex editor. Copy the first 78 bytes from the 89u file (which is not anything copyrighted, for those who were about to yell so, since it is only the header and not AMS code) in front of all the hex in the tib file. Save it. Using tib reciever and tilp, send the thing!

WARNING: DO NOT do this if you have no idea what you're doing. Also remember to use the "install product code" command to restore AMS when you're done fooling around.

I think your right since, form what little I know about this, it is the signed section of the code that makes it possible for transfer.

Do this in *nix (in a Bourne-compatible shell like bash):

(dd if=[anyfile].89u of=[tibfile]2.tib bs=78 count=1; cat [tibfile].tib) > [tibfile]2.tib

or something like that, replacing [anyfile] and [tibfile] with the base names of the respective files.

I can't help bragging - I submitted the story to slashdot.

I see OS News and GeekNews have taken it up too, now.

Good thing it hasn't overloaded the servers - then I couldn't brag.

Actually, our load never went over 0.5 (it should be completely un-noticeable until at least 4 or 5 on this system) and our network bandiwidth never went over 25% uage.

So it's no problem. As long as you have reasonable hardware (200MHz machine is enough, just make sure you have at least 256Mb RAM and decent disks) and a well-designed software, you can easily handle it.

Oh yeah, aod for the interested, there were some 18,000 people clicking on those links from slashdot (according to our referral logs, which are of course not 100% correct due to browsers not sending referrals).

Also, the percentage of Linux based browsers increased drastically - no surprise there.

err... I sent you an e-mail four days ago, and haven't gotten a reply yet. Do you not check it that often, or something?

I stand corrected. I just received your response.

For the record, I do not read my @ticalc.org mail every day. So don't expect a reply right away. I do read it eventually, though.

I guess I'll brag too and say that I sent the e-mail letting Michael know about this program release. :-)
Cheers!
