7:57 pm - A1200 connection to broadband internet

aerofox
I have an Amiga 1200 which I would like to get back in operation.

It has a Viper 1230/28 RTC Also known as a M-Tec T1230/28 RTC
68030 accelerator which when it has 8 megs of memory installed, makes the PCMCIA slot useless. I could just use 4 megs, but even 8 is anemic :P (I would use my Apollo 1240, but it unfortunately is defective)

So, how to connect it to the internet? I found this device which appears to be a bridge between a serial device and ethernet. From what I understand, it emulates a modem and will provide a PPP connection to the broadband router. (That is if I'm reading things correctly?)

Does anyone here have any experience with something like this? $182 is a bit much to spend and find out it doesn't work. I would be using the dial-up TCP/IP software that comes with OS 3.9

6:11 pm - Sonic the Hedgehog demo

coyoteseven
A long long time ago (in a galaxy far, far away), I remember downloading a demo for Sonic the Hedgehog for the Amiga. It only worked on versions 1.2 or 1.3 of the operating system and it was a very faithful reproduction of Sonic 1's Green Hill Zone, sans the parallaxed background. It also had, as I recall it, some rather nice music which I've never heard anywhere else. It wasn't really too functional though, beyond being able to move Sonic back and forth along a side-scrolling map.

I'm basically wondering if anyone else remembers this (and it's not just some fevered dream I had at some point, lol)? Was it an actual demo created by Sega and then distributed or somehow leaked out? Or was something fan made? I do recall that Sega did put some ads in Amiga magazines, looking for programmers for their games (and saying something to the effect that the Genesis platform was very similar to the Amiga).

a good way to get the absolute value of %d0.w ?

11:52 am - Another Amiga legend gone

grimmtooth
Those of you that were with the Amiga early on may remember a gal named Asha Develder on Compuserve, GEnie, FidoNet, or, more recently, TAML. Unfortunately, she has passed on.

12:11 am - Amiga Palettes

jerronimo

For those of you who might be curious, I just determined the hex values of all of the palettes in Amiga OS 1.x and 2.x. They are as follows:

(1.x color ordering rearraged to better fit with the 2.x ordering)

1.x
        blue    black   white   orange
        05a     002     fff     f80

1.0 (Musicraft)
        lblue   black   white   orange
        77c     002     fff     f80

2.04    
        gray    black   white   blue
        aaa     000     fff     68b

        a96     002     fff     779

Dunno if anyone besides me will find this useful, but there you go

11:40 am - The mask of Zorro 1...

coyoteseven
Apparently the folks over at The Big Book of Amiga hardware have all forgotten the existence of the Zorro 1 specification. Take the Pal Jr. as an example. They have completely confused the Z-1 slots for Z-2, and go as far as saying they are some kind of "custom configuration" or so.

I ought to e-mail them or something and remind them. The Pal Jr. and Amiga 1000 expansion boxes like it adhered to the original Zorro 1 standard. Zorro 2 didn't come out until that part of the Amiga 2000 design had been finalized.

Both Z-1 and Z-2 are the same as far as bus specifications are concerned; as they found out you can plug in half sized Z-2 cards into a Z-1 slot and they will work. But Z-1 had a completely different form factor. The expansion cards were square.

I wish I still had my old Amiga magazines from the time, where this was all clearly explained and I remember it well! I'm sure someone else out there remembers this. I mean, there was a reason why Zorro 2 was called "2" and not "1", haha!

8:16 am - Redrawing Andy

jerronimo

So, back in 1985, at the launch of the Amiga, A little-known artist named "Andy Warhol" digitized and colored an image he had captured Live(1) of little-known musician named "Debbie Harry". [Video on Google Video -- fast forward to 12:00 in]

As far as I've been able to determine, there are no digital copies of this imagery in existance, not anywhere public anyway.

One thing that I started to work on, and I'd eventually like to accomplish is to re-compose the original 64,000 pixels of that 320x200 image from that press conference footage (which is on the Cloanto Amiga Forever DVD in its entirety) by hand.

I had started to do it by re-scaling the image in Photoshop, and doing various bits of processing to get the base done, then started tweaking by hand, but I'm starting to think this is completely the wrong approach.

The correct approach is: Set up my Amiga 1000(2) with the A1300 genlock. Next, either use the Amiga Forever DVD, or build a new DVD with properly scaled imagery to fit the screen as perfect as possible, playing that DVD on repeat through the genlock. Next, fire up Deluxe Paint 2 and draw on the blank slate with the correct pixels; pixel for pixel, to recreate the imagery.

Depending how hardcore I am, I could instead use GraphiCraft, since it's a direct descendant of "ProPaint" which is what Andy used originally. If I could find that, I'd gladly use it.

Yeah. I'm a geek. I totally accept this.

(1) Pun: the hardware he used was a precursor to the "Live!" framegrabber. (2) which is now in storage.

Sometimes, when you're using your modern computer, with your 2+ Ghz CPU and WinXP or Vista, and sometimes it might seem to lock up or hang, perhaps when its moving data from the swap file or whatever, but you're suddenly paranoid that a crash is imminent...

Do you sometimes find yourself turning your head to look at the computer's power light to make sure it isn't blinking?

3:15 pm - Greetings from a Female Amiga Fan

amiga_rippermod
Hello all Amiga-maniacs. I'm a girl with a huge passion of my Amiga 500 since 1996. I still adore Amiga but unfortunatly she's "dead" (some keys such as CTRL ALT Amiga SHIFT and the mouse clicks are all broken) but I still have my own Amiga PC with me.

I have a channel at YouTube.com with the same username as my LJ and I hosted a few vids of some Amiga games of my own. I have a program named Lemonade that I download from LemonAmiga.com website. You need a WinUAE and kickstart ROMS to run it. I got theme with a simple help of some "partners" of the Lemon website


I still need to do more recordings...however I still play lots of Amiga games.

My fave from all times is of course "The Settlers" and with that whole passion of War and Strategy games I created a community about Settlers and other related games...

Find it at
the_settlers1



C yo all!

I held off posting this until I got some confirmation, but alas it is true: Fred Fish passed away on 4/20/07.

A fine fellow, he was.

Does anyone here have a CatWeasel Mark IV?

I'm asking because I have one, with two SID chips on it. Only I haven't used it since I re-installed Win XP on my computer. I had to remove it because of stability issues, and this is why I thought to ask right now.

Had anyone else had problems with the CatWeasel drivers causing your Win XP system to become unstable? Version CWMK42000 caused a lot of problems, while earlier versions did not. I've since that since I've last had it in my computer, a new version of the drivers has come out, which makes me curious.

I'd really like to put it back in my machine. I got it a year ago and it makes my computer a bit unique. As well as the 5.25 inch floppy driver. ;P

8:36 pm - Good times

grimmtooth
If you haven't read it, Jason Scott has a great precis of the early Amiga demoscene on his blog today: http://ascii.textfiles.com/archives/000365.html. It's a nice little tribute.

If you don't know who Jason is, block off some time before going over there. It's worth a long visit.

10:41 am - Amiga 1000 Rebuild

jerronimo
So I decided to revive my Amiga 1000. Back in college I re-grounded and replaced the PALs on the daughterboard, but I did a poor soldering
job
... namely, I took a shortcut which worked for a while... some of those center pins never saw any
solder. Over time, they corroded and it all stopped working. The last time before this week that I actually
had it working was bout 8 years ago at this point.

I put up loads of pics for those interested.

In any event, I've encountered a problem. I soldered the PALs directly to the board, since I couldn't find any sockets at home, which works,
as I
can get it booting now. (The floppy
drive being vertical thing no longer is true. It works horizontally now.)

Here's the problem...

It seems like some colors aren't being generated properly. all 12 levels of Red look perfect. green and blue do this weird stepping thing. Rather than the effective values being "0 1 2 3 4 5 6 7 8 9" for example... it's treating them as "0 1 0 1 0 9 8 9 8 9" It's like one of the middle bits of the value are being ignored. I looked around on the net, and found reference to a color issue being a result of a bad 74HC244 in the video circuitry, so I think this might be related. I tried a different Denise, but to no avail.

here's a movie that demonstrates the issue:



Does anyone have any clues for me?

10:06 am - sure... it seems obvious now...

jerronimo

Since the recent comment in "The Joy Of Tech" about the OS X 10.5 feature that gives the desktop multiple desktops.. "Wow. Virtual desktops.. They're finally part of the Mac OS? How quaint!" it got me thinking.

On the Amiga, sure, you can have multiple screens up, which you can pull down to reveal, hide, resort, etc... but Workbench never used more than one screen. AmiWM does, since that's all it does, but not the original Workbench...

The concept of multiple desktops existed back then... at least to the very early 1990s (since I remember things like TVTWM and such) but they never made it over to Workbench.

In retrospect, it seems totally obvious... multiple Workbench screens, each with different apps running on them (for workbench-screen apps), different file browsing windows open, etc.

So... yeah. Virtual Desktops were sooo almost there, but not quite. I guess I didn't really have a point with this.

9:36 pm - We've got SID

coyoteseven
Well seems like my CatWeasel is working fine afterall!!

I plugged the audio cable into the internal AUX input on my motherboard. That was all I had to do. Now I'm hearing all that 8-bit goodness coming out of my speakers. It's great!

I switched the SID chips around so that chip #1 is the one that came from the C-64 I had lying around. I got it from my high school way back when, when they were switching over to another platform and that one had a broken keyboard. That way I get to hear it play with the current CW drivers.

I got my CatWeasel MK4 today and I've installed. It came with a SID chip pre-installed as I ordered, plus I plugged in one more, taken from an old C-64 I have lying around. They are both 6581's.

Well, I jumpered it according to the diagrams. I plugged in the floppy drives correctly as I can make an image of an Amiga disk now, and both WinVICE and ACID64 seem to recognize the SID chip (though they mistake it for a CatWeasel MK3).

The problem is that I'm not getting any sound. It appears to play, but... nada. I got the audio output connected to the CD-in on the motherboard, so the sound should be coming from the speakers connected to it. I've verified that the speakers are hooked up correctly too. I'm not sure what's up!

Might be a driver issue. Might be that one of the SID chips is busted. I'll have to swap them and see if that doesn't make a difference.

11:10 am - Amiga 2000 progress report

coyoteseven
Well, as suggested to me, I snipped off the battery last night from my Amiga 2000 motherboard and cleaned the area off some more as best I could. It looked like the battery leaked on one side and not the other. The top silked layer, or whatever it is, was worn off. At one spot I could see the copper colored traces. Eep! I thought maybe that could be my old A-2000's doom.

With nothing else connected to it, no expansion boards, floppy drives, mice or keyboard or anything at all but the power supply, I plugged it in and hooked up the b/w video output to a television. I turned it on but I got nothing. No signal or anything. The power LED did not even change brightness, it just turned on and stayed on. I was about to become dismayed, but then I thought that maybe all the socketed chips needed reseating. I turned the computer off and did just that. Every socketed chip made a slight creak as I pushed them down, gently but firmly, and I did so until they creaked no more!

I turned my Amiga 2000 back on. This time it actually came to life. The "Insert Workbench" screen came up, showing that it was running a Kickstart 3.1 ROM. Excellent!
