#3567219 Thrifty McNifty

Posted by Airshack on Sun Aug 7, 2016 11:17 AM

Funny how it's named after a slide rule. Airline pilots once carried large bags with all sorts of charts and heavy manuals inside. Now everything they need to carry is conveniently stored on the iPad. My company calls the iPad and associated software, ELECTRONIC FLIGHT BAG. Reminds me of the Beverly Hillbillies referring to their swimming pool as the CEMENT POND.

#3567215 Any Cheats/Tips to Bypass 4-Sprite Maximum on Horizontal Line Limit in XB?

Posted by Airshack on Sun Aug 7, 2016 11:11 AM

If you haven't already accomplished the F18A upgrade you're in for a real treat. VGA out to a nice 19" Samsung monitor ($10 at Goodwill) makes everything better in the TI world. Remember in the Wizard of Oz when everything B&W turns to color? It's simply that dramatic! New graphic card also removes the four horizontal Sprite limit.

I believe this page in the XB manual is where you need to concentrate. This leads to the calls: PATTERN, DISTANCE, POSITION, and LOCATE.

#3564341 Velocity to Animated Sprites?

Posted by Airshack on Tue Aug 2, 2016 6:03 PM

For a multi-colored animation:

A. Hide another Sprite (of another color and/or pattern, using CALL LOCATE) off the bottom of the screen by positioning it on to the last row of pixels.

B. Use CALL POSITION to find where your Sprite needing animation is located.

C. Momentarily reposition the hidden Sprite to that location using CALL LOCATE.

D. Move that Sprite back to the hidden row using CALL LOCATE.

This technique is found in the Miller's Graphics book, SMART PROGRAMMING GUIDE FOR SPRITES.

#3564337 Velocity to Animated Sprites?

Look specifically at lines 230 and beyond:

PATTERN subprogram
CALL PATTERN(#sprite-number, character-value [,...] )
The PATTERN subprogram allows you to change the character pattern of sprite without affecting any other characteristics of the sprite.

Sprite-number specifies the sprite you are using. Character-value may be any integer from 32 to 143. See the CHAR subprogram for information on defining the pattern for characters. See the MAGNIFY subprogram for more information.

The program below illustrates the use of the PATTERN subprogram.


Lines 110 through 140 build a floor.

>110 CALL COLOR(12,16,16)
>120 FOR A=19 TO 24
>130 CALL HCHAR(A,1,120,32)
>140 NEXT A

Lines 150 though 200 define characters 96 through 107.

>150 A$="01071821214141FFFF4141212119070080E0988484 8282FFFF8282848498E000"
>160 B$="01061820305C4681814246242C1807008060183424 62428181623A0C0418E000"
>170 C$="0106182C2446428181465C3020180700806018040C 3A6281814262243418E000"
>180 CALL CHAR(96,A$)
>190 CALL CHAR(100,B$)
>200 CALL CHAR(104,C$)

Line 210 creates a sprite in the shape of a wheel and starts it moving to the right.

>210 CALL SPRITE(#1,96,5,130,1,0,8)

Line 220 makes the sprite double size. >220 CALL MAGNIFY(3)

Lines 230 through 270 make the spokes of the wheel appear to move as the character displayed is changed.

>230 FOR A=96 TO 104 STEP 4
>260 NEXT A
>270 GOTO 230

(Press SHIFT C to stop the program.)

hmmmm hard to say. Contacts clean and OK ?

You could use the "HP USB Format Tool" (v2.2.3) to lowlevel- format it once, maybe this helps.

Just google it, it is common. Only use FAT32, OK, but maybe once low level format it with NTFS, and 2nd step back to FAT32...


The fact that the card is working on the PC does not mean that it is technically OK at all.

Maybe just dump it, not to get in risk with your data....

Or sell it on ebay "as is" :-D :grin: :D

I've been using the suspect card in my camera for a few years without fault.

Do you have a pic from the non-working (and the working one) SD-cards, just to see them (want to read the imprint) ?


Yes! The one on the right will not work for some reason?

The new guy appreciates the MG.hfe. I'm seeing these things for the first time and their pretty damn cool!

#3542990 Lotharek .hfe disk image links?

Posted by Airshack on Thu Jun 30, 2016 9:30 PM

SUCCESS! I finally got the HxC Rev-C working today! Special thanks to you guys for the .hfe files! Cool! I love this thing! My straight ribbon cable worked out and it wasn't tough to make. Joking actually, my crimping tool crushed a few of the connectors before I got it just right. Time to look on YouTube to see what's wrong with my technique.


Next item: Why does one of my SD cards behave with the HxC while three others are no-go? Of course they've all been formatted Fat32 and have the same config file placed on the as the first file.


This makes me want to write a TI how-to for the Lotharek site. Group effort would be nice to get everything right.

OH Wow! Thank you both... I have an original controller (for the time being) so I suppose the 40 track. i don't know enough about this thing quite yet so maybe just a few of both SSSD/DSSD. Thanks!

#3540607 CorComp RS-232

Posted by Airshack on Mon Jun 27, 2016 1:59 PM

I just picked up a CorComp RS-232 for my PEB. Wondering if there's any issues with this device vs the TI card? Are you TI geniuses privy to any resources for a CorComp manual or anything else of related interest?



#3526417 How to turn off a PEB card?

Posted by Airshack on Mon Jun 6, 2016 10:09 PM

The best way to turn off any card in your PEB is to unplug it and mail it to me.

#3526330 How I installed my F18A in my extra Ti-99/4A

Posted by Airshack on Mon Jun 6, 2016 7:50 PM

I went to ACE hardware and purchased a pack of furniture spacers intended for elevating couches off wooden floors. I set the PEB atop these spacers and run all my cables underneath the PEB. Helps with cooling as well -- airflow and all. Some solutions are just that simple. Cost $7.

#3506698 New PEB question

Posted by Airshack on Sun May 8, 2016 10:29 PM

Thank you for saving me the disappointment of purchasing an empty box for $200. Wow. I continue to have a problem.

TI gear seems unavailable here in Phoenix, AZ. I've searched flea markets, etc - nothing. I've recently ordered a 99/4A and I'm excited about revisiting my earliest programming days from the early 1980s.

Recently the nanoPEB and CF7+ solutions have evaporated - unavailable. So, I'll ask, how can I code and store on the TI without a functioning PEB and floppy disk drive?

Also, how did the CF7+ die? Are they available on the secondary market?

Thanks in advance guys...
