Here is another project of mine, Built Amiga 2000!
This is a big project and taken me over a week to build!
Stage 1: I Did all Diodes and Transistors.
Stage 2: I Did all Ferrite beads and axial fuses.
Stage 3: I did all Resistor Networks.
Stage 4: I added Zorro slot 3 x RCA jacks RGB port and 2 x 9 pin ports to protect the components while i was soldiering and added all resistors too!
Stage 5: I added all Ceramic Capacitors Axial and Radial type. that taken me the longest to do as there was shed loads to do! and added Electrolytic capacitors too!
Stage 6: I Added the rest of the I/O Sockets, power connector, battery holder, Video Hybrid, Crystal Oscillator, Jumpers, Floppy header and Power Led Header!
Stage 7: I Added All EMI capacitors
Stage 8: Added all Sockets!
Stage 9: Added all Zorro, ISA Slots and video slot too!
Stage 10: Installed all Chips ! She looks like an Amiga 2000 now! She has a bluster chip not buster!
Now time to test!
It power on and no smoke that a good sign!
Kickstart 3.1 screen came up and it's alive!
Now to put Amiga test kit in and run all test!
As you can see, Amiga boots floppy drive okay no issues, It has kickstart 3.1 ROM and OCS and pal too!
I added Zorro 8MB ram card to see if zorro Cards work! and yes it does, but there is an issue, More on this a bit further down!
Tested all CIA's all working correctly
Serial port Working!
Parallel Port Working!
tested RGB, Sound, mouse, joypad and keyboard all working!
Game Boot fine and working!
Now here is an issue i have with Zorro Bus!
This is 8 Mb ram card it works on my A500 plus and 4000D with no issues but when i put it into this A2000 it comes up with errors! but only on Amiga test kit software!
I have clean card, re flowed all Zorro sockets just in case of cold joint and tried all 5 Zorro slots and same result error. and i have change the jumper on card to 4mb and same result!
However I Have notice when I first switch Amiga on with or without Zorro card installed I get a green screen flash for like half second then it's gone and boots fine. (not same green screen as if you have chip ram error, it's a darker green screen)
I booted to workbench and filled up ram disk with floppy disks to make memory full to see if Amiga crashes from that error in Amiga test Kit, But no it didn't crash it filled memory up and was working fine no issues! as you can see in photo! which is weird that it works in workbench without any issues!
then I put in DiagRom and did Ram test on that with all 5 Zorro slots that had taken a while to do but no Issues there either!
So if anyone has an idea on why It has a green screen on power up only (warm boot is fine) and why Amiga test kit showing error on fast ram, then any feedback would be great!
I got feeling something to do with bluster!
