invisible kid Posted February 16, 2023 Share Posted February 16, 2023 (edited) If you mean reversing the option/basic mechanics, OPTION=BASIC ON is much much much more convenient. Advanced users will be using this, and even if we get caught by surprise by the reversal, we will learn and appreciate I think.

So, booting up without any devices, nor touching the option key, goes straight to the self test. 1 Quote Link to comment Share on other sites More sharing options...
Mathy Posted February 16, 2023 Share Posted February 16, 2023 Hello Brian If you're thinking about removing or replacing the audio test, how about something that tests for the presence of a second Pokey? Sincerely Mathy Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted February 16, 2023 Share Posted February 16, 2023 Basic on or off can be controlled via software and always has been except for the original cartridge but there might be trick to that as well. I would have loved that feature to have been utilized on boot disk commercial games for sure. Fun times. I had to reverse the Altirra tick mark for BASIC. This isn't an all the time logic reversal correct, as in it only affects option during boot time like other solutions and not BASIC control across the spectrum.

Sincerely Mathy Hello, That's an option, of course. I am worried about going down that path due to feature creep. Something else could be put in other than the self test. But, there's only 2k to work with. I was actually contemplating the ACE 80XL until I found out it was 4k. lol I am open to suggestions.

reifsnyderb Posted February 17, 2023 Author Share Posted February 17, 2023 Once I removed the music note display, from the audio/visual test, I was able to stuff almost the entire self test code into the self test bank with 68 bytes to spare. Outside of the self test bank, there is now 1,119 bytes free. There is now plenty of space to put that peripheral handler loading facility, that was hidden for 40 years and never used, back in. 4 Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted February 17, 2023 Share Posted February 17, 2023 (edited) The Self Test was broken but fixable, It all could have been combined into one screen with the memory test fixed it could have helped with a number of diagnose my crap scenarios. Pokey/Graphics test was NOT really useful that's pretty certain. Edited February 17, 2023 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
reifsnyderb Posted February 17, 2023 Author Share Posted February 17, 2023 It looks like the Peripheral Handler Loading Facility takes up over 800 bytes. It's almost back in. I hope to see somebody make something for it within a few months. 😕 Realistically, there is about 284 usable bytes left. Quote Link to comment Share on other sites More sharing options...
reifsnyderb Posted February 17, 2023 Author Share Posted February 17, 2023 Support now added for internal parallel devices. (It only took 10 bytes. 🙂 ) I found code for the numeric keypad and am thinking about making it part of the OS. Thoughts? Current status: ;* Revision 4.99 (600XL/800XL/65XE/130XE/800XE/1200XL) ;* Added the following fixes and changes from Revision 3 (600XL/800XL/1450XLD) through ;* Revision 3, Version 4 (600XL/800XL/1450XLD) ;* Added IDCPU back to First 8k ROM Identification and Check ;* Fix initial address for RAM sizing to $4000 (16k). ;* Fix initial address for equivalence cartridge checksum to $BF00. ;* Correct mishandling of NAK. ;* Initialize PDVS to zero. ;* Added support for internal parallel devices.

reifsnyderb Posted February 17, 2023 Author Share Posted February 17, 2023 (edited) The first support for the CX85 Numeric Keypad is compiled in. It can be enabled (toggled) via SHIFT-CONTROL-3. (3 was picked because it's SHIFT/3 is the pound or number sign) The computer boots up with this support disabled so that 2 player games of MULE can be played without a problem. Also, the keypad support is on joystick port 2. I left the function keys as per Atari's example code: https://atariwiki.org/wiki/attach/AtariCX85/Atari_CX85_Numerical_Keypad_Technical_Reference_Notes_1_page.pdf But the return key (F1) and backspace key (F2) are hokey. I'll have to look into that some more. Tested with real hardware..... testos.rom Edited February 17, 2023 by reifsnyderb 3 Quote Link to comment Share on other sites More sharing options...
reifsnyderb Posted February 17, 2023 Author Share Posted February 17, 2023 The logic looks good. I am wondering if the problem with F1 and F2 is my keypad. Through BASIC, it returns the right values, though. Quote Link to comment Share on other sites More sharing options...

No. The F1 key is returning a 0 and the '0' key is returning a 0. The F1 key is special because ALLPOT is read. Bit 4 is masked out, inverted, and shifted to the left. That result is OR's with PORT A (which is right shifted 4 times) to become the number looked up in a table. Like this: CX85 = * ;entry LDA STRIG1 ;Key pressed? BNE CX8510 ;Exit if key not pressed LDA #$00 ;Reset attract mode STA ATRACT ; Determine value of key pressed LDA PORTA ;Read port 2 LSR A LSR A LSR A LSR A STA CX85T LDA ALLPOT ;Read ALLPOT for 5th cable pin stat AND #$08 ;BPOT bit mask EOR #$08 ;Invert bit ASL A ORA CX85T ;A has key value LDY #$00 ;Table index CX851 CMP TCX85,Y ;Check for match BEQ CX852 ;If found, proccess the value INY INY LDX TCX85,Y ;End of table?

Was it only the (now simplified) Selftest ? Yes. The space eventually came from self test space. There is a lot of self test code and related tables outside of the banked self test area. Once I removed the self test code a lot of space was made. I was also able to move almost all of the self test code into the bank. 3 Quote Link to comment Share on other sites More sharing options...
reifsnyderb Posted February 18, 2023 Author Share Posted February 18, 2023 (edited) After studying the code and realizing that the only key that isn't working right is the F1 key on the CX85, I am thinking the problem may be my CX85. But, I can't confirm this as I don't have another to try. If anyone has a CX85 and can test this that would be great! I changed the CX85 keys around to what was specified in the instruction book as opposed to the programming book. In the instruction book the function keys are arrow keys and the "enter" key is a return key. Here's the latest build. testos.rom This one is compiled with the Atari rainbow logo...just for grins. Edit to add: Boot with Option for BASIC and Shift/Control/3 toggles the CX85 driver on and off. The CX85 works on port 2.

The official definition of ALLPOT in the Hardware Manual is that 0 = valid, 1 = invalid for each POT0-7 register. But what it actually means is whether the POTn registers are actively loading from the master counter that counts up from 0 for each scanline during the pot scan. While the caps are charging and the input is below threshold, the ALLPOT bit is 1 and the POTn register continually updates from the master pot scan counter. It flips to 0 once the register stops updating and the value is locked in, which happens either when the cap voltage reaches threshold or the scan finishes. Normal pot scan takes 228 scanlines and is triggered by stage 2 VBI around scanline 256, so the scan is always completed at the start of the VBI. This guarantees ALLPOT=0 at the start of the VBI, which is why your code is sensing the 0 key rather than the ESCAPE key. Try using POT3 instead. 1 1 Quote Link to comment Share on other sites More sharing options...

Rybags Posted February 18, 2023 Share Posted February 18, 2023 (edited) If I was removing the Self-Test I'd insert some powerup code to give feedback on the initial Ram test on coldstart. Maybe something like 1/10th second green background then go to black and continue for a pass. 1/5th second red background, maybe have a beep as well then go to black and continue for a fail.

Showing extended memory would be nice, too. However, I don't know how much code would be needed to show all possibilities. (i.e. RAMBO vs Compy, etc.) If somebody has some code that could scan this, and is willing to have it added, I would certainly be interested in adding it if there is space.
