That would be great if Mr. Atari would join in. 🙂 Quote Link to comment Share on other sites More sharing options...

I don't get the reason for that one. The comments make it look like using all caps was a mistake. Quote Link to comment Share on other sites More sharing options...
reifsnyderb Posted February 16, 2023 Author Share Posted February 16, 2023 (edited) I think the cold start is now working correctly and has been enabled. I figured a version number of 4.99 is sort of appropriate. So, I put it in provisionally. Here's the latest ROM file: testos.rom Looking for feedback. 🙂 Here's where it's at now: ;* 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) ;* Fix TXEB table for XE banking. ;* 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. ;* Accept device number 0 (like revision B did) ;* Added the following changes from Revision 4, Version 0 (600XL/800XL/1450XLD) ;* Removed Peripheral Handler Loading Facility. ;* Add support for SIO fast mode (38,400 baud). ;* Processing of Control F1 through Control F4 no longer affects PORTB. ;* Reduced KRPDEL from 48 to 20 for NTSC and from 40 to 20 for PAL. ;* Reduced KEYREP from 6 to 4 for NTSC and from 5 to 4 for PAL. ;* Left margin set to 0. ;* Added OS version number to self test main menu ;* Re-added F1-F4 keys to the keyboard self test. ;* Shift-Help toggles international character set. ;* Control-Help sets left screen margin to 0. ;* Shift-Control-Delete cold starts the computer. ;* BASIC loaded only when Option key held down ;* Brian E.

adam242 Posted February 16, 2023 Share Posted February 16, 2023 (edited) Okay, hardware newbie question here... what model EEPROM would I need to burn this on to try on real hardware? And would it be possible to flash this into one of the AtariMax APE 32-in-1 OS slots? Edited February 16, 2023 by adam242 Quote Link to comment Share on other sites More sharing options...

You'll need a 16k EPROM. I am using an M27C128. For some reason, EPROM's are usually sized in kilo bits. So, a 16 kilobyte EPROM, with 8 bit bytes, will be 128 kilo bits. It is possible to use higher capacity EPROMs but then you end up soldering jumpers to the pins. 1 Quote Link to comment Share on other sites More sharing options...

Possibly. You'd have to figure out the offset for the OS slot and the chip would have to be able to be erased. So, assuming you don't have an image of the chip, I'd put the chip in a burner and read it. Then, save it to a file. You could then calculate the offset for the OS and overwrite an existing OS. Xgpro allows you to do this in it's buffer. If not, you'd need a hex editor. Then, you can burn the image to the chip. 1 Quote Link to comment Share on other sites More sharing options...

No soldering is necessary for a single OS in a larger EPROM as I have found that a 27C256 or 27C512 can be used by loading the 16KB OS ROM data to the last 16KB EPROM data bank, 4000-7FFF or C000-FFFF respectively, as the unused address lines at pins 1 & 27 are held high within the Atari thus permanently selecting the last 16KB bank. This makes it easier as you can use any of the three suitable 28 pin EPROMs 128K, 256K and 512K. 1 Quote Link to comment Share on other sites More sharing options...

There's no free space. Interestingly enough, some of the self test tables are located outside of the self test memory bank. (i.e. The table with the keyboard characters on it.) To save space, it's almost worth simplifying the self test code. Edit to add: Removing the keyboard automatic "test" code would save a few bytes. I am not sure how many. That always seemed useless. I don't see the point of the audio-visual screen. It could be combined with another screen as we know the video works when we can see something. 🙂 Edited February 16, 2023 by reifsnyderb Quote Link to comment Share on other sites More sharing options...
+Stephen Posted February 16, 2023 Share Posted February 16, 2023 I always thought the entire self test was useless. I'd have rather seen the space used for an ML monitor, or mini DOS. 1 Quote Link to comment Share on other sites More sharing options...

I'd have rather seen the space used for an ML monitor, or mini DOS. That's what I did on my OS used in my portable. I reclaimed the space for the self tests, the international character set, plus a bunch of other areas in the XEGS OS ROM, to hold my BIOS menu system, the compactflash support, etc. A big part of the self test area is banked, so you need to keep that in mind. I used the cartridge space in the XEGS ROM (normally holds missile command) for my monitor/debugger. There was too much code to shoehorn into the normal ROM memory map. 2 Quote Link to comment Share on other sites More sharing options...
reifsnyderb Posted February 16, 2023 Author Share Posted February 16, 2023 I disabled the feature for automatically performing all tests and move some of the self test tables into the banking region. There is now 894+ usable bytes available in the OS region. I think some sort of self test is helpful. But this thing is a hog. The space used just for the audio/visual section is nuts. Why do I need to see notes on the screen? I have a screen, so it's obvious that works. Having the sound test would be good, though. Maybe all 3 screens could be combined into 1? The space saved would be nice and there just might be around 460 bytes left, in the self test bank for @Mathy 's Atari Fuji code. 4 Quote Link to comment Share on other sites More sharing options...
invisible kid Posted February 16, 2023 Share Posted February 16, 2023 (edited) I agree 100% Minimize the tests to just the facts, mam. Use that shit for something else. Keyboard test program is useful, mainly for the booping sound when a key is pressed, don't need all of the custom graphics.

My computer was the problem with the video. I just watched it on a phone. (Go figure.) Anyhow, did you get a chance to try it with the Option key held down? Maybe I should leave the Option key alone?
