Description: This is my "Holzbrett" (pronounced "hold-s-bread") and means "wood board"  :-D

On this board you can see (left hand) an A1000 (PiggyPack PAL-Agnus Rev.A) and (right hand) a PeeCee (sorry, its a intel PIII700 .. but i got it for free).

Starting on the left side, you will find the following parts:

- 1,76MB HD-Diskdrive
Teac FD-235HF with prototype HD-FloppyFix
this is THE prototype which made it possible to support the A1000 with the HD-FloppyFix
it can read/write/format in 1,76MB/1,44MB/880KB/720KB (FFS/OFS/CrossDOS-FAT)
Copyprotected games, various bootloaders and copytools are workin 100%.
There is also a testreport on the actual AmigaFuture

- MultiVision2000-Flickerfixer
The flickerfixer is mounted on a selfmade B2000-compatible videoport, nearly all signals are coming denise (3 signals are taken from the rgb-port)

- Kickstart/BootROM-switch
Selfmade Kickstart-Socket (512KB ROM) and BootROM made switchable for uptodate Kickstart and 100% retrofeeling
The selfmade-guide is on www.a1k.org, if someone wants to translate it to english .. contact me!

- Interfaceorgy
mouseport -> ps/2-interface -> kvm-switch -> trackball
a1k-keyboard-port -> a2k-interface -> ps/2-interface -> kvm-switch -> keyboard
Denise -> MultiVision2000 -> kvm-switch -> monitor
peecee -> kvm-switch -> keyboard/trackball/monitor

the amiga is conected as "master" ... double hit on ctrl to change the system (amiga-peecee/peecee-amiga)

the win/menu-key is supported as "cycle trough screens" on the amiga side, but works only on kick2.x and up (simulates AMIGA-M) .. under Kick1.x you can only flip to the first screen, not back.

- peecee
normal intel p3 700mhz with matrox g200 and realteck 8139C network and 128MB mem .. nothing special here

- onboard sound
speakerset modified to work with 12V from ATX-psu
speakerset is conected with the a1000 (peecee as no soundcard)

300 Watt ATX-PSU modified to power the peecee and the Amiga1000.
It is modified to generate the needed TICK-signal.

- wooden controlbox
main powerbutton / peecee-reset-button
amiga-power-led / peecee-hdd-led / peecee-power-led
internal peecee "biep" speaker
amiga-switches (left sided)
BootROM / KickROM - switch
extra amiga-power-switch (for amiga-shutdown/hw-testing/ without rebooting the complete system)

- wooden block in the middle (extra picture below)
it is called it the "BDU" babylon docking unit
i will place a interface board the with left hand zorro-signals and right hand pci-signals
on these interface board i will conect the babylon-interface later on .. which is allready only existing in my mind.
(my target-project for 2008 ...)

So these holy bitch is only made for "babylon-development" ...  :-D

First of all: WOW, this is simply AWESOME!

To answer your question Ratte/Andre, the problem is the language, that's why there are no questions. What I mean is: I'm very interested in all of these sub-projects (and of course the main), but I don't want to tire you with petty questions about "how did you do the FDD-fix", etc, etc, before I RTFM. Once I can read your comments and descriptions in a1k.org (only in German right now), then I can start asking questions. Imagine if you had to answer thousands of questions... Babylon would never be finished :-(

Perhaps you can write the comments and description in a second thread, but in English, as you make progress through the project.

Can't wait to see more!

Can you please tell me more aobut that kickstart switch/romboot you made? for the a1000 :)

I can't read german language.

If you have any drawing of the design, can you please email it?

My email is:


Thanks :)

Wow! So how close are you to producing this?

November 14, 2007, 06:38:10 PM
But I miss some comments or questions about all the other stuff on the wood board!

I think nobody noticed, that there is a NORMAL PC DISKDRIVE with full Amiga-HD-Support!
Thats not the old "use a PC HD-Drive for the Amiga as a DD-Drive" story ... its 1,76 MB !!!

There ar no questitions about building a kickswitch for the A1000, with KickROM and BootROM.

No questions about the selfmade Videoslot ...

... adding a TICK-signal to ATX-PSU ...

Hmm, it seems to be that A1000-Users are rare on Amiga.org ?!

... just like a 060-board, it will use some of its memory as "fastmem" for real speed.

the pci-bridge will translate PCI to ZORRO ... and will act like a CPU-BOARD on the ZORRO
This CPU-Board is "emulated" by the x86-System

So the x86 machine functions as a fast emulated 68k processor?

November 13, 2007, 08:53:52 PM
lol the possibilites are endless, PPC emulation and u can run OS4 on it  :-)
November 13, 2007, 08:21:38 PM
@apache2k: ... target -> PicoITX ...

The amiga should be connected to the x86 with a pci-bridge.
the pci-bridge will translate PCI to ZORRO ... and will act like a CPU-BOARD on the ZORRO.
This CPU-Board is "emulated" by the x86-System.

Next year i start modifiing an existing pci-bridge and bus-converting.
3,3v <-> 5v signals and so on ...

x86 as CPU-Board on the Amiga

Can you explain this a bit more? (in English please :-) ) I'm curious to know how the x86 CPU interfaces with the Amiga. Is there some kind of translation in between to make it function as an Amiga accelerator? Does it run an emulated 68k processor? Or is it used for running x86 code, like a brigeboard? Also, how real is this? Is it more than just an idea?

November 12, 2007, 08:59:40 PM
I can't read / speak German. Someone mind filling me in?
November 12, 2007, 08:17:25 PM
ahh now I understand what the thread on a1k.org is all about :)
November 12, 2007, 08:09:53 PM
Very cool!  :-D
Just put a glass over it and you get also a nice desk? Haa? and some lights under it.

On the other hand maybe u got it wrong , people try to get everything in to a smaller packet ... this hmmm.. :lol:
November 12, 2007, 07:06:04 PM
What a mess! Couldn't you have put all that in one of those big towers?
November 12, 2007, 05:09:52 AM
Sorry, I forgot to explain what "babylon" is good for ...

Short: x86 as CPU-Board on the Amiga
schematics after brainstorming, made by botfixer (a1k): Babylon.pdf

The link inside the posting isn´t working, here is the new link to the german forum.

More in 2008 ...

What is this freak-of-nature? What am i looking at? I don´t get it.. :-?
