morelenmir Posted July 16, 2015 Share Posted July 16, 2015 I'm not sure how you mean. Candle's SimpleStereo is controlled directly by P4/M1 on the Ultimate board. Lotharek's Dual Pokey requires a U-Switch board to turn logic 0/1 into a substitute for a mechanical switch. The effect is identical: turning the second Pokey on and off. Let me rephrase; when "System->Audio->Stereo" is enabled in "Altirra" I see under "System Clock and Features" that "Stereo Pokey" is enabled. However, the actual sound I get is over the left channel only, nothing on the right. However, from my experience - of Lotharek's version of "SimpleStereo" at least - the mod should still output balanced mono from both L&R even when explicit, separated Left and Right channel sound is not being generated.

flashjazzcat Posted July 16, 2015 Author Share Posted July 16, 2015 No idea, I'm afraid. As long as the Stereo Pokey BIOS option sets P4/M0 correctly, I'm happy. Quote Link to comment Share on other sites More sharing options...

Fair enough - I guess it might be a problem with the 'test 18' of "Altirra". I'll make a post over there in a moment. The last thing I will mention here is - while the "Stereo Pokey" enabled/disabled state does correctly reflect the option in "Altirra"s 'System->Audio->Stereo' setting, the actual item itself is greyed in the BIOS menu. Therefore I cannot actually use it to turn 'on' or 'off' the simulated mod. I have attached a picture of the screen. On the real hardware perhaps this will enable?

Any stereo mod I have used behaves that way. Original pokey is left, and 2nd pokey is right. I have not used the Lotharek module, but I have never used a mod which did balanced mono when using just one pokey. Quote Link to comment Share on other sites More sharing options...

When enabled, but only outputting normal system and mono-game sounds they only gave one channel? Quote Link to comment Share on other sites More sharing options...

Therefore I cannot actually use it to turn 'on' or 'off' the simulated mod. I have attached a picture of the screen. On the real hardware perhaps this will enable? Use of the four bits controlling the four pins of the P4 header is completely arbitrary: that's why I implemented plugins so their use could be changed. Altirra doesn't connect pin M0 of P4 to stereo enable/disable and there's really no need for it to do so, given you can control stereo using the emulator settings. The Stereo Pokey option in the BIOS will only control your stereo board if it's connected up to pin M0 as I explained earlier (directly if it's one of Candle's stereo boards, or via U-Switch if it's one of Lotharek's). If you don't have it connected, the option will be greyed out as per your picture. If you have stereo present and it is not under Ultimate 1MB's control, the hardware status should be accurately represented in the "System Information" menu.

Just to be clear - one channel only when the "SimpleStereo" is not enabled, but two channels when it is? This even if just generating normal - mono - system or game audio?

flashjazzcat Posted July 16, 2015 Author Share Posted July 16, 2015 Stereo on, but no stereo-aware hardware hitting the second Pokey chip = sound out of left speaker only. Stereo off = sound out of left speaker only. 1 Quote Link to comment Share on other sites More sharing options...
morelenmir Posted July 16, 2015 Share Posted July 16, 2015 Interesting! Whatever the case it clearly isn't the "Ultimate1MB"'s fault one way or the other, however I'm wondering if you have an older version as this is directly from Lotharek's site: Main features : - GTIA sound mixing on both channnels - Dual Mono/STEREO switch - Stereo Indicator Led - high quality PCB I took the second item to mean when off then balanced mono on both channels, but when on one pokey in to each channel.

flashjazzcat Posted July 16, 2015 Author Share Posted July 16, 2015 Heh... without proceeding further off-topic, let me revise my earlier conclusions now that I have the correct stereo cables plugged into the back of the 1084S: it does appear to mix mono sound.

spookt Posted July 17, 2015 Share Posted July 17, 2015 (edited) Hi Jon Quick possible bug report. I'm on real hardware and I'm seeing odd results with the cold reset (SELECT+RESET) function. If I hit select+reset the system resets to a blank black screen. Hitting reset on it's own at that screen will bring the system back but not perform a cold reset. Instead I get back to an SDX with TDline running and a C:> prompt, oddly my custom margin settings are gone. I've tested with shift as the reset modifier and it shows the same behaviour. Cheers Paul EDIT: I've just found that if I hit any key (seemingly) on the blank screen the system then boots!

flashjazzcat Posted July 17, 2015 Author Share Posted July 17, 2015 Quick possible bug report. I'm on real hardware and I'm seeing odd results with the cold reset (SELECT+RESET) function. Thanks Paul: I'll have a look at that. Haven't tested that in a while so perhaps something's broken. Sounds like it ends up sitting in a keyboard polling loop somehow.

Roydea6 Posted July 17, 2015 Share Posted July 17, 2015 Jon, On my second 800XL running the new Uflash.xex from a partition and selecting and item to dump to file I get and ERROR box [Error #$8b] [OK]. Hitting any key I can then select an SIO drive D1: to dump or upload the slot and It works on SIO.. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted July 17, 2015 Author Share Posted July 17, 2015 (edited) That's a CIO read-only error. What was the default drive ID before you switched to D1:, and is there any device attached? UFlash catalogues the SDX logged drive by default. Were you trying to save to the PBI HDD? Is global HDD write-protect enabled? Is the partition's lock flag set?

Roydea6 Posted July 17, 2015 Share Posted July 17, 2015 Jon, I can't even get it to read FDISK or The Last Word this is with a SIDE2.. My SIDE1 cartridge works okay... So it seems that this 800XL doesn't like the SIDE2... APTDEV reports ok APTDISK reads the partitions CHECKAPT preforms ok Just Fdisk not finding an APT Not a big deal this 800XL is usually in storage and I can always use the SIDE1 cartridge with it.. I was just busy getting the new BIOS AND PBI 13 installed and I was able to do that.. Quote Link to comment Share on other sites More sharing options...

You might want to swap out the "SN74LS08N" IC or replace it altogether with an "SN74F08N" unit. Quote Link to comment Share on other sites More sharing options...

No luck with this Bios28 on this machine I also had no luck with the swapping of 74LS08 and 74F08N. So back to storage now that I have the BIOS AND PBI13 installed..
