jmccorm Posted February 7, 2018 Share Posted February 7, 2018 There are some fairly complex programs and simulations. This is the first Lunar Lander that I've run into where you can overtemp and destroy your main thruster. 3 Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 7, 2018 Share Posted February 7, 2018 Indeed. I will be making a video showing how to walk around the system soon... Isn't it amazing? There are over 16,000 lessons on cyber1... -Thom Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 7, 2018 Share Posted February 7, 2018 It's worth noting that ALL the programs you are using, were written in a language called TUTOR, not just by the systems people, but by ordinary PLATO students, teachers, and users. You can ask for lesson space and make your own programs. (I want to make a multi player berzerk) -Thom 2 Quote Link to comment Share on other sites More sharing options...

I managed to come across a lab on writing programs for TUTOR, called 0csix and 0cseven, but it looks like I don't have permissions. I've tried other educational labs, and it looks like I don't have permission for those, too. Do they fine-grain permissions so you have to ask for each or is there some way to get blanket access to a wide breadth of educational material?

tschak909 Posted February 7, 2018 Share Posted February 7, 2018 (edited) I have recorded, a completely impromptu long-form video showing the patched PLATO cartridge: If anybody has requests on videos to make regarding PLATO, drop them here or in the atarian notesfile. I'd love to see everyone jump on! -Thom p.s. I show the "touch" screen bits around 22:00. Edited February 7, 2018 by tschak909 3 Quote Link to comment Share on other sites More sharing options...
16kRAM Posted February 7, 2018 Share Posted February 7, 2018 Kudos, Thom! I'm so impressed how quickly you and Steve solved the issues. Here's my personal hack. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 7, 2018 Share Posted February 7, 2018 Kudos, Thom! I'm so impressed how quickly you and Steve solved the issues. Here's my personal hack. Should we do a canonical disassembly, so we can start hacking on it? I do know we should crank up the baud rate, at least. -Thom 3 Quote Link to comment Share on other sites More sharing options...

Hopefully the Atari is able maintain its rendering chores at speeds higher than 1200. Quote Link to comment Share on other sites More sharing options...

Hopefully the Atari is able maintain its rendering chores at speeds higher than 1200. ICE-T can handle 9600 baud with a software-rendered 80 column display. 2 Quote Link to comment Share on other sites More sharing options...
jmccorm Posted February 7, 2018 Share Posted February 7, 2018 ICE-T can handle 9600 baud with a software-rendered 80 column display. Related, the Altirra serial port emulation (with TCP/IP connections) seems to pseudo-connect to Plato at 9600. Where the Atari bottlenecks is on actually drawing the screen data. I find myself often using the F1 key to accelerate the screen draws. I should probably go into System -> Speed Options and lock it at some multiple like 300%, but the only problem I've found is that while I have things accelerated, the key repeat engages too fast. I seem to remember there is a memory location in the Atari somewhere to adjust the key repeat delay and the repeat speed? I also wonder if there is an Altirra option to slow down key repeats while the emulator is running faster than 100%? Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 7, 2018 Share Posted February 7, 2018 (edited) well, it only REPORTS connecting at 9600. This disparity is literally to deal with brain-dead telecom and BBS packages, and can be set when you're setting up the "modem" device in Altirra. If you explicitly set rate throttling, then Altirra will throttle the connection to the baud rate asked of the R: device. -Thom Edited February 7, 2018 by tschak909 Quote Link to comment Share on other sites More sharing options...
evilmoo Posted February 7, 2018 Share Posted February 7, 2018 I started disassembling here: https://github.com/jduerstock/tlp You're welcome to add/use/steal and/or tell me you hate ca65. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 7, 2018 Share Posted February 7, 2018 Fantastic. I've started a note on PLATO for it and let the cyber1 people know. Hopefully we can get some mileage out of this. -Thom Quote Link to comment Share on other sites More sharing options...

I do know we should crank up the baud rate, at least. -Thom I think that's a great idea, while this is IMHO, done very well, I bet some of the better tools and mathematical choices of today could improve things, faster baud rate and a wider variety of serial, pbi, ethercart choices might be made available. Currently this is bound to a limited scope of serial device modem choices. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 7, 2018 Share Posted February 7, 2018 If we made an R: handler for the dragon cart, that would be sufficient, I think. -Thom Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 8, 2018 Share Posted February 8, 2018 Good news: Steve Cox was able to change BAUD rate. Bad News: The 850 and the terminal program can handle 2400 reliably, MAX. The relative ROM offset $17EE is the operand of an LDX instruction that gives a target BAUD rate: $0a = 1200 BPS $0b = 1800 BPS $0c = 2400 BPS $0d = 4800 BPS $0e = 9600 BPS So with that, here's a patched ROM: TheLearningPhone-patched.rom -Thom 4 Quote Link to comment Share on other sites More sharing options...
+MrFish Posted February 8, 2018 Share Posted February 8, 2018 Having a problem with both versions of the hacked ROM: when in the "Bigjump" and using the + key to scroll down the list, it always bails out at the point shown below, prints the text "OK" off to the left side of the list, and then Altirra's connection status changes to "(in command mode)". At that point I can do nothing but reboot and start over. I can type text, but nothing seem to have any effect on the mode I'm stuck in.

tschak909 Posted February 8, 2018 Share Posted February 8, 2018 hurfff... I haven't hit this problem, yet. I'm thinking the guard character needs to be disabled somehow. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 8, 2018 Share Posted February 8, 2018 Probably don't use three +'s in a row for now. Quote Link to comment Share on other sites More sharing options...
+MrFish Posted February 8, 2018 Share Posted February 8, 2018 Yeah, I can get to the bottom of the list using a combination of +, +, - repeated enough times. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted February 8, 2018 Share Posted February 8, 2018 The guard time is what's killing it. If we can set a new guard time, then we can prevent this from happening, dunno if we can do e.g. ATS12=255 or not... if we need it, need to ask phaeron to add it. -Thom Quote Link to comment Share on other sites More sharing options...
