Omega-TI Posted April 17, 2015 Author Share Posted April 17, 2015 OMEGA.dsk If this doesn't inspire you to finish the program, nothing will. Thanks Gazoo, I promise take a look next week when I have some more time, but seriously I haven't a clue about where to start or what to do when it comes to ASSembly language. When I see cryptic stuff like this... ... my eyes just glaze over and my mind goes numb as it means absolutely nothing to me. #Micdrop All you gotta do is pull out the EA manual and read Tony's comments... Oh yeah, some of my college text books were smaller than the E/A manual! Seriously, with my memory issues, lack of time. lack of basic understanding... Et voila. An easy crash introduction to assembly for ya, Kevan! Groan, I promised Gazoo I'd take a look, I'm seriously doubting I'll comprehend anyone of it....

Retrospect Posted April 17, 2015 Share Posted April 17, 2015 If the source is there, then you just have to worry about how to save the code to a disk image (or real disk?) and how to load (or call) it. As i know nothing about it either, I'm no help at all. Just so ya know - you're not on your own. Quote Link to comment Share on other sites More sharing options...

The code you quoted is part of the standard utilities that write to the screen, look for files on peripherals, look for keys, etc. I pretty much just copy that stuff into every program I write so I can use it when needed. You don't need to understand that part, just use it. The code earlier in the file that's commented is the part where you tell the utilities what to do, and is much easier to understand.

Opry99er Posted April 17, 2015 Share Posted April 17, 2015 Matthews assembly thread is a phenomenal resource. Based on the conventions in that thread, I was able to do quite a bit of assembly stuff when I applied myself. Understanding what the registers are (R1,R2...R13) and how they are used to accomplish tasks is a really good place to start. BTW, the EA manual is not a tutorial for beginners. I learned that the hard way. but guess what... We have (in the dev rec thread) a copy of Lottrups book.... Which is the bees knees, IMO. Try writing a HELLO, WORLD! program first. It is easy and fast, and anyone can do it. I have tried dozens of programming languages over the years (never really mastered any) and I always do the HELLO, WORLD! program to see how I like the language. I remember when TheCodex got me working in Java. I liked the UI of Eclipse alot. Just try it... Learn how loops work, how to manipulate registers. I'm terrible at assembly, but if I needed a routine or a small program, I could whip something up. And so can you, buddy. Quote Link to comment Share on other sites More sharing options...
Opry99er Posted April 17, 2015 Share Posted April 17, 2015 Simple delay loop. DEF START START LI R1 1000 TOP DEC R1 CI R1 0 JNE TOP END (L)oad (I)mmediate Register 1 with "1000" DECrement the value in R1 (reduce by "1") ©ompare (I)mmediate the value in R1 to "0" (J)ump if (N)ot (E)qual to TOP (Loop) If the values are the same (R1 and "0") then END It has been a while, so I might be a little off, but you can see that it is very legible and understandable. It is not harder than BASIC, it just takes more time and a few more instructions. You are completely at the helm in 9900, and you can run your program off the bridge. You can also drive alot faster. To be "good" at it, you need an understanding of the memory map... Something I lack (which is why I am not a very good assembly programmer)... But for basic stuff, assembly is really just broken-down BASIC. You're BUILDING the CALL CLEARs and the CALL HCHARs by hand. No limitations. Truly awesome.

Asmusr Posted April 17, 2015 Share Posted April 17, 2015 You are missing a few commas DEF START START LI R1,1000 TOP DEC R1 CI R1,0 JNE TOP END And CI R1,0 is not really needed because most instructions compare the result to 0 automatically.

Opry99er Posted April 17, 2015 Share Posted April 17, 2015 I put the CI in there to make it easier to understand. The 0 could be a 10 or 56... Then it would be required. Quote Link to comment Share on other sites More sharing options...
Gazoo Posted April 18, 2015 Share Posted April 18, 2015 Well, there was a way cooler way to do this. I just couldn't resist. Having been pretty intimate with the PGRAM DSR, it seemed to be a better idea to just modify the code it uses for CALL PTIME. That way the clock can be displayed as it's running. You only need to change it if you choose to, otherwise you can run BOOT or quit. Since this code is lifted from the PGRAM DSR, it won't run on an emulator. You need a real CORCOMP or PGRAM clock for it to work, else you will find yourself viewing the TI title screen. It certainly was a lot of fun coding this on a PC and running back and forth to the TI to test the code. Dsk file is attached. Program name is SETCLOCK. BOOT is included on the disk with a menu entry for DSK1.SETCLOCK so you can go round and round in circles if you want. The path 'DSK1' is in the first sector of SETCLOCK if you want to change the disk number. If you want to change it to a subdirectory on a hard drive and lengthen the pathname, contact me and I'll make a custom version for you. SETCLOCK.dsk Have fun, Gazoo 1 Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted April 18, 2015 Author Share Posted April 18, 2015 One H U G E THANKS Gazoo! This is just too Freaking Cool for words. I love the way it keeps on ticking on the screen. A program like this was way overdue for the TI. Your version is way better than anything I envisioned. 1 Quote Link to comment Share on other sites More sharing options...

sparkdrummer Posted April 18, 2015 Share Posted April 18, 2015 Fantastic! Gives me a reason to crack open the box and replace my triptech battery. Many thanks Gazoo!!!! 1 Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted April 18, 2015 Author Share Posted April 18, 2015 Wish I still had my Triple Tech card. This is pretty cool! I wonder, since that new new speech interface of Greg's is so small, even with the speech attached, would there be enough room (height-wise) for small FPGA clone of the stand-alone CorComp clock to plug in too? Could it even be done? True, it would only be a 'Double Tech Card', but really, now days who would use the 64K printer buffer anyway?

Gazoo Posted April 18, 2015 Share Posted April 18, 2015 (edited) SETCLOCK.dsk Here's an alternative to the SETCLOCK program. It's been renamed BOOS, and altered a little. Put it in the same directory or on the same disk that you keep BOOT. When it is loaded, the header tells the loader to load the next program in the chain, so it loads BOOT and BOOU. When selection #2 is made, it jumps right into BOOT, which is already loaded. Gazoo Edited April 18, 2015 by Gazoo 1 Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted April 18, 2015 Author Share Posted April 18, 2015 That's pretty freaking SLICK there Gazoo! I copied BOOS over to my main program disk and it works great. I had a small issue with the version of BOOT you had on that disk though, but it did not occur with my version. Well, I have start getting ready to go. L8R! P.S. Awesome way to think outside of the box! Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted June 30, 2015 Author Share Posted June 30, 2015 Gazoo, Your program is fantastic, I like it as much now as ever and it does get quite a bit of use actually. Now since you like 'a challenge', from time-to-time, and seem to be an expert at adding AWESOME features to already great software, it occurred to me that there is room for 'one more' feature. So if you ever get bored, I have a possible idea.... Replace option 2 with "Sync PC Time" Granted this might be difficult as it would have to obtain the time from somewhere. One method to do this would be to have a small PC program running in the background that could be accessed via the UDS-10 in Telnet mode, (preferably with the same settings one uses for the BBS). It would give the PC's time to the TI and your program would do the rest. Anyway, that was just an idea that popped into my head as I was using your program this morning.
