Nice! Seemed like it was a lost cause from your other threads. Good for you. I'm glad you got it going.

Nice!!
I still have work to do on my A1000..
I can solder a bit (it needs some), but I'm afraid of my level for the work.
I don't mind breaking most of the things I solder, and I haven't yet.
But I don't want to break my A1000, so I'm in a wait state..

Nice seeing yours boot to KS 3.
I'm still not sure about that on mine..  Part of me likes keeping that part of the A1000 original..  

Nice seeing you're up and running..  Might motivate me to get back to work on mine. ;-)

Ah cool, I read somewhere it had some software it needed? Week is a pretty good sign...

See this page:
http://amiga.resource.cx/exp/search.pl?product=&company=Microbotics

  • a simple battery backed up clock
  • time is read by a CLI command, it does not take over the system clock
  • connects to the A1000's 2nd mouse port
  • once the port has been used (eg. by reading the clock or pressing fire on a joystick) the MouseTime clock puts itself to sleep making the port totally transparent - but the time no longer can be read from the clock until the next hard reset
  • passthrough connector


I've seen that. Strange little clock. My A1000 is in really good condition, inside and out, which makes me a little uneasy about cutting into it. Maybe I'll look for a second unit to work on....

All you need now is KickTOS!

I am confused. It says it's an Amiga 1000 kickstart disk but it's already had kickstart loaded, otherwise you wouldn't get the hand.
 
Atari ST emulation on the Amiga isn't new, you could do it back in the day.
 
If I had an A1000 I might be tempted to make it boot from ROM and turn the WOM into RAM (pretty sure there was a way of doing that). However I think ultimately I would leave it original.

No, the hand on the Amiga 1000 -when you first turn it on- is asking for a Kickstart Disk, not a Workbench disk.  Once Kickstart is read then it will present another hand for Workbench.  Much like you see on other Kickstart ROM based Amigas.

If I read everything right, the KickTOS disk loads a copy of TOS (Atari ST's based OS) into the area where Kickstart normally goes.  Then the Atari emulator points to TOS so you can run Atari ST stuff.

A long time ago I did work on Medusa (an Atari emulator) and had to do a bunch of TOS work.  It was a neat project but I was also just a kid...

Still, this is pretty cool!  :-)

It was my understanding that KickTOS wasn't an emulator, that it was a hacked TOS that ran native on the Amiga... essentially turning your A1000 into an Atari ST, but with a bunch of dormant amiga hardware.  It loads TOS into the WCS, then just runs natively from there as if it were an ST.  Or am I mistaken?

This is my understanding too, but the version of KickTOS I have is PAL and in French. Is there an NTSC version in English?

You are probably right.  I only read a brief summary.  The Atari ST is pretty simple and cobbled together from basic off-the-shelf parts.  I guess it would be pretty easy to load TOS and then patch system calls to handle the memory addresses.  

I read somewhere else that after TOS there was only like 64k (?) left for patching which isn't enough to do everything they would like.  

While its impressive today, imagine what kind of a stir this would have made back in the day.  Wow...

BTW, I realized today that the ICD Shuffleboard sits under the Gary -- which does not exist in the 1000.

Ah, well.  I am going to fit my 40MHz Derringer in today or tonight...

Ok, more good news; got everything working today. I had two big hurdles to get over:

1. DKB Insider had a broken pin, repaired it with a leg cut from another IC and soldered it on.
2. The IDE cable header did not fit, so I filed it down, now all sits nice.

A little more clean up and blasted with air can. More easily seen here:

Test Boot, I get a yellow screen only when I boot from the early startup-sequence. But seems fine. Normal boot, the yellow does not happen. Crappy capture does show some off colors that are not there in reality. But the yellow is real.

That's an ICD Shuffleboard you have on the CIA, right?  Amiga Resource says it goes in the Gary... I am confuse...

Yes CIA, right where you see it. I have the manual, I was gonna scan it.

Would be a great benefit to myself, and probably others, to have the correct installation information.  If you do scan it, I would appreciate a copy, and it would be neighborly if you were to submit it to Installer's Heaven.

I'm going to put mine in tonight.  Having the internal DF0: hanging there makes me nervous.  Plus, I think I can use the floppy power to supplement the power and ground to the Derringer.  I might build a quick regulated supply to cut the noise.  I need to pull up my 1000 schematics to assist.

Yup!  Got my shuffle board installed and moved to the 1011, which draws MUCH less power than the internal.
