H to cycle through the CLU/PI (channel related but not yet sure what exactly that stands for)
J to cycle through the TS (timeslot) once you selected a PI.

Ctrl-H and Ctrl-J cycle backwards through the respective diagnostics.

Apparently I wrote the disk image onto a bad disk and it caused the problems I was having. Got it written onto a good disk and IT BOOTS!!!!!!

Gonna have to build a custom startup-sequence for this, tailored to my system, to check for 3.1 ROM, and if present softkick 2.04 ROM.

It seems to work on my 3.1 ROM, sorta. It doesn't switch into interlace mode and it causes my genlock to output a signal that is constantly drifting to the left (but otherwise "stable", no skewing across scanlines), and the palette on the upper half of the screen is messed when it loads images. Still seems to work better on a real A2000 than emulation when it comes to 3.1.

Got two good disks here now, one write-protected as my physical "master", and the other one for day to day mucking around.

Excellent work

you'll have to let us know how it goes, I'll give it a try on my a2000 (if it still works!

) but trying to focus on the reverse-engineer, so if it has already been done once, that will speed things up

Lots of definite correlations.

1) All special items in the scrolling grid (e.g. the two messages prior to HBO/channel 25) correspond to odd items in the CLU list (e.g. LO708B and LO708I).
2) However not all items in CLU list are shown on the grid (at least during the time period I checked: Windows time of test was 12:00 AM on Apr 2 '99 -0700, a.k.a. PG time: 10:00/10:30/11:00 PM).
3) DITTO = apparently items whose listing never changes (not confirmed by checking whole 24 hour period).
4) ALTHILITESRC = blue highlighting.
5) HILITESRC = red highlighting.
6) Can't figure out what "None" means (I thought at first that it must mean no highlighting, i.e. that you would either see "ALTHILITESRC" or "HILITESRC" or "None"; however CLU entries 0 and 1 have both "None" and "HILITESRC" ... and some like CLU 4 have neither.)

swest77: And you say you don't need to come to the IRC channel because your Amiga knowledge is waning...lol

tin: I do think that is best - you are much better at figuring out what means what in terms of RE'ing...you should come to IRC too, so we can all talk in realtime.

Oh, if you didn't see on the wiki, I updated one thing - N does in fact switch the top half to color 0, even on my genlock - I fed a random video source (my PS2 running Guitar Hero II, since the PS2 generates a stable NTSC video signal) through my genlock, and even though it doesn't work properly with regards to dissolving between video and Amiga graphics, when I hit N, the top half shows perfect PS2 video while the bottom half shows Amiga graphics. Quite interesting that this still works even with a non-UV genlock. If I don't put my control sliders to be 100% Amiga video, however, other than in "N" mode, when A2-Blue generates color 0, the external video drifts to the right. I really need to find a UV genlock from the AP2000 machines (as opposed to the genlock seen in the EPG Sr. machines). If anyone here has one, feel free to send it to me (I have no money to buy one, and that's assuming that one could be found separated from it's A2000).

Edit: LOL, as an aside, I ran mIRC a couple of days ago with this laptop set to 4/1/99. Now it says "You have been using mIRC for 4074 days, which is beyond the evaluation period." I've also noticed that, despite the fact that I reset the Amiga clock on every disk boot, that the last few times I've rebooted the disk, it's basically started back up as if the time hadn't been reset. No idea if it's actually changing the system clock or keeping track of the differences. I need to Ctrl-C out of ESQ on the diagnostic menu and check the date, which will answer this for me (unles ESQ is devious and resets the Amiga clock on exit).

Oh, and for the record, I have three disks now - one virgin, one "master" with my modified startup, and one for day-to-day operations. I figure, if nothing else, I can backup the file with the local text ads, and restore to the modified "master" as needed.

Edit 2: In the listings, there is an entry saying "Spice will feature an alternate audio feed [music] between the hours of 6am-10pm. This is to comply with Section 505 of the 1996 Telecommunications Act.". I looked it up, and it leads to section 641. This is what it says:

1996 Telecommunications Act Sec. 641 wrote:`SEC. 641. SCRAMBLING OF SEXUALLY EXPLICIT ADULT VIDEO SERVICE
PROGRAMMING.
`(a) REQUIREMENT- In providing sexually explicit adult
programming or other programming that is indecent on any channel of
its service primarily dedicated to sexually-oriented programming, a
multichannel video programming distributor shall fully scramble or
otherwise fully block the video and audio portion of such channel
so that one not a subscriber to such channel or programming does
not receive it.
`(b) IMPLEMENTATION- Until a multichannel video programming
distributor complies with the requirement set forth in subsection
(a), the distributor shall limit the access of children to the
programming referred to in that subsection by not providing such
programming during the hours of the day (as determined by the
Commission) when a significant number of children are likely to
view it.
`(c) DEFINITION- As used in this section, the term `scramble'
means to rearrange the content of the signal of the programming so
that the programming cannot be viewed or heard in an understandable
manner.'.
(b) EFFECTIVE DATE- The amendment made by subsection (a) shall
take effect 30 days after the date of enactment of this Act.
SEC. 506. CABLE OPERATOR REFUSAL TO CARRY CERTAIN PROGRAMS.
(a) PUBLIC, EDUCATIONAL, AND GOVERNMENTAL CHANNELS- Section
611(e) (47 U.S.C. 531(e)) is amended by inserting before the period
the following: `, except a cable operator may refuse to transmit
any public access program or portion of a public access program
which contains obscenity, indecency, or nudity'.
(b) CABLE CHANNELS FOR COMMERCIAL USE- Section 612(c)(2) (47
U.S.C. 532(c)(2)) is amended by striking `an operator' an
inserting `a cable operator may refuse to transmit any leased
access program or portion of a leased access program which contains
obscenity, indecency, or nudity and'.

I bet that was quite inhibiting to viewers wanting to get their rocks off, seeing as they had to listen to music instead of the requisite moaning that comes with watching porn. Good thing that nowadays, adult channels are digitally restricted through addressable converters, so that no matter what time of day it is, the viewer can discreetly watch porn with all the proper sounds, without it being available to underage viewers who tune their sets to the adult channels without prior authorization (so that the signal is descrambled).

Edit 3: Ok, I checked the date after exiting from ESQ - it stated that it had only been three hours and change since I booted the system (I set the clock to 14:00:00, and it said it was 17:xx:xx) - I definitely need to back up the local ads and restore from my modified master. I just rebooted and was told that it was 14:00:00, but when ESQ fully ran, it said it was 6:45pm, exactly as it was before rebooting.

Quite interesting that this still works even with a non-UV genlock. If I don't put my control sliders to be 100% Amiga video, however, other than in "N" mode, when A2-Blue generates color 0, the external video drifts to the right. I really need to find a UV genlock from the AP2000 machines (as opposed to the genlock seen in the EPG Sr. machines). If anyone here has one, feel free to send it to me (I have no money to buy one, and that's assuming that one could be found separated from it's A2000).

Just so you understand, these UVGEN units are _RARE_. The hard part is not having the money to buy one, but rather to find one.

Man that is such a shame. I guess most of them are in the bin.

I have left my Amiga off for about a day now. Given the fact that I've restored from a virgin disk, and only copied over my modified startup-sequence and local.ads, it stands to reason that it's possible for the software to be storing something in battery backed RAM. Does anyone here actually know how much battery backed RAM a standard A2000 has? I'm having trouble finding out. I'll try booting it up in a little bit and seeing if it resets to 4/1/99 12pm on the listings. Either that, or it stealthily stores info on the hard drive and re-reads it on boot. I'll check for that next time I boot it as well.

If anyone ever comes across the later UV genlock card, and feels like spending the money to acquire it, feel free to send it to me for testing purposes. I'll gladly send it back once it's no use to me, but well after I make some videos

I know how hard it is to find rare shit - I spent several years trying to find a decently-priced cartridge copier for the Sega Genesis, and finally found one when I came across an eBay auction that was selling a Genesis with one - I bought it for $100, and have refused to sell it even though I've been hard up for money and could probably get $75 for it alone.

Edit: I booted up the A2K. Even after all this, it still says it's 4/2/99. I modified s:uv-startup to display the date right before launching ESQ, and it said it was a few seconds after 2pm on 4/1/99...when it boots up, it says 4:13pm on 4/2/99. This is fairly serious in regards to running the software on a real system, as it means that the software is storing the last known time somewhere that isn't on the floppy. I will try one last time to restore from a virgin disk and copy over only my modifications (local.ads, s:startup-sequence and s:uv-startup). I only have two ideas for where it's storing this - either clock RAM or DH0:. Since I'm pretty sure AP2000 units didn't have a hard drive (wasn't the SCSI controller disabled?), I'm thinking it's unused bytes in clock RAM, since the software had no access to DH0:.

Edit 2: Ok. I restored to a virgin master disk, and the only thing I did was copy SetCPU to the c directory so it'd be available when I disabled DH0 and booted from the disk under 2.04, so I could use it to move the 2.04 ROM from chip RAM to fast RAM. Even after all of that, and ensuring that the date was 4/1/99 14:00:00 before ESQ booted, it still said it was 4:xx pm on 4/2/99. It has to be clock RAM.

Amiga knowledge needn't be one in the same with general software intuitiveness. Just means I barely remember the hardware.

Incredibly mysterious, this phantom clock issue. See, clock RAM, evidently with extra space for stuffing unrelated data. That's something else I had and have no clues about in the Amiga world.

So all I can say is, good luck there.

About mIRC, if you're using 6.35, change offsets 6354C / 6354D / E6BEF / E6BF0 / E74FA / E74FB in mirc.exe from 85 / C0 / 74 / 27 / 74 / 36 to B0 / 00 / 90 / 90 / 90 / 90. Its /registration command will then become magically permissive (and internet activation-ignorant), and clock-driven messages will bug you no more.

Oh, and I remember that stupid Telecom Act crap. Cable scrambling technology (except Zenith's PM/PZ and I think SSAVI scrambling methods) back then did not secure the audio carrier whatsoever, so even if there was no useful picture, you could still listen to any scrambled channel's audio loud and clear.

Hey Guys,
I know I am a bit... off topic. Please excuse me for being offtopic

Now, I was wondering if anyone knew how to get it to show the listings. I read the thread, but it still wont work after setting the date to April 1 1999. It returns Error 007. The time is 9:22 PM in the emulator. Anyone know how to fix this?

You may have obliterated the cached listings inadvertantly at some point. Save the local.ads file from the root of the disk, and restore to a virgin copy of the disk as you originally received it, and then try again.
