I bought one of these on here and interested in finding more information about this board and any upgrades.
Had a search on the old Google search engine but couldn’t find anything 🤷🏻‍♂️

This board has a lot on upgrades over the original ACIL board. For example a Clockport header. Does this give a faster or same as the A1200 Clockport?

Any links or info greatful.
 
This is through AI search.

The Saft6luck Rev 2.2 Amiga 4000 motherboard is a modern reimplementation of the original A4000 board with numerous upgrades designed to enhance performance, compatibility, and functionality. Here are its features in detail:

Key Enhancements:

1. Memory Improvements:

ChipRAM: 2MB integrated directly onto the PCB (eliminates the need for the 74F841 chip).

FastRAM: Supports up to 112MB using configurable SIMMs (1MB to 64MB per module).

Double-Sided Modules: Compatibility with 2x32MB or 1x128MB configurations.

2. Kickstart Upgrades:

BIGROM Integration: Supports 1MB Kickstart ROMs while remaining compatible with original ROMs.

Kickstart Switch: Integrated to toggle between different ROM configurations.

3. Modern Connectivity:

Clock Port Header: High-speed A1200-compatible clock port for expansions like USB and networking.

I2C Integration: Includes a 3.3V I2C bus for peripherals, with fan controllers and voltage monitors.

4. PCB and Component Design:

Drill Holes: Converted from vias for better reliability during assembly.

Simplified Layout: Removed unused "option" jumpers and unnecessary ICs to streamline the design.

RTC Battery: CR2032 socket with integrated diode fixes.

5. Additional Features:

Fan Support: Three fan headers (2x12V, 1x5V).

H/V Sync Buffers: For enhanced video signal quality.

Power Supply Options: Includes jumper-configured power for IDE DOMs or CF adapters.

Connector Improvements: Updated holes and dimensions for modern DB23 and RCA connectors.

6. Miscellaneous Fixes:

Delay-line compatibility for both 14-pin and 8-pin SMD versions.

Improved reliability for stacked connectors.

Enhanced power-up reset functionality and dedicated NMI connector.

Sources:

AmiBay sales thread detailing the features and upgrades.

Saft6luck Rev 2.2 upgrade documentation and user discussions.

Maybe @saft6luck can confirm and/or add something.

Thanks 👍🏻🙏🏻

So looks like the Clockport is a faster version… Maybe worth trying out the trident I have to see how it performs.
 
The full story can be found here https://www.a1k.org/forum/index.php?threads/90658/.
Please consider to contact me in case of questions, too :)

The clockport is configurable (see jumper). I would be interested in the performance of the trident.
Fantastic! Nice to see the creator of this board be in here 👍🏻

I wasn’t aware of the jumper for the Clockport? The board I have acquired from the seller is sort of 98% complete. So I have ended up adding the RTC chip, the Clockport header pins and the floppy select jumper pins. None of the power headers are populated. So will have a look out to see about the jumper for the Clockport.

Not sure if you are looking for further advice on maybe a later revision of this board? But one thing that I feel that needs to be added. Are some sort of pins for the RATTE monitor switcher to connect to the CIA chip, as the board I have has the Sockets fitted for the CIA chips. The RATTE comes with a 3 signal connector to detect native Amiga output for the switch from RTG mode and vice-versa. The adapter normally clips over the CIA chips. On the Rev 1.5 A1200 recreated boards a 3 Pin header is added to the board for this.

For the IDE port. Does this have the PIO modes mod? Or was this abandoned due to issues? I know reading about a mod being made available for up to attain a PIO mode 2. But believe this was problematic.

Thanks for what you have achieved and delivered so far 👍🏻
 
PIO 2 should work but I flash the standard version only. You can replace the GAL easily as it is in a socket.

A connector for the RATTE switch is a good idea. For more ideas, the a1k forum thread would be the perfect place.
 
@Boing-ball I have an Acill a4k mobo as well and ran into the same issue with the Ratte switch. Would love to know if/when you come up with a solution :)
 
Who is "you"?

My solution looks like this:

My only current solution with the Rev 2.2 board is to either:

1).. Remove the CIA socket and have the CIA directly soldered onto the board. So that the current adapter fits over the CIA chip.

2).. find a way with either soldering into the correct pins for some extention cables or pushing in some cables into the socket.
 
That would work 👍🏻 What is the SCSI enable jumper? Is that currently on the rev 2.2?

This is for V2.4 with SCSI on Board (see A1k forum).

Instead of removing the socket (and soldering the CIA on the board to use a socket to connect to the CIA) you can use PIN 6 of U305 to get access to _CTS.

GND and 5V is all over the board but also at U305.

As an alternative you could use a PLCC plug, solder the CIA on this one and put it back into the socket. Then the RATTE connector socket fits onto the CIA.

Thanks 👍🏻
Will have a look at U305.
It’s good that this A4000D board is still being worked on. Exciting times! Great stuff 👏🏻
Will try my best to interpret the German (Deutsch) Language over on A1K 😉
 
@saft6luck. May have found a compatibility issue with Rev 2.2.

Just to let you know, I have just struggled to get a Warp Engine 040/060 to this board. Every power on I just get a dark grey screen on power up. On putting the board back into an original Rev B board. All is well.

Not sure if this is to do with the Kickstart ROMS (3.2.2 47.111). Even though the same ROMs are being used on my original Rev B commodore board. Or maybe it’s something else?

What I have tried to diagnose:

Nothing on the main board. Just left with the onboard 2MB chip. Just power and the Warp Engine. No issues if I 0lug in a Phase 5 Cyberstorm 060/PPC as this starts up no issues.

Just putting it out there 👍🏻
 
The board was tested with the late version of the warp engine 4040 and did work. If I can borrow your board I might be able to trace down the problem.

Hi,

Thanks for the prompt reply. I can confirm that the Warp Engine I have definitely works fine when plugged into a Commodore Rev B board.

When I picked up this card off another sales site. I had no clue to the revision. When I put a wanted thread up for a 060 upgrade for it, a few stated it was a rev 2. But looking on the big book of Amiga Hardware, it maybe a rev 1.
I have attached a pic of mine with a few heatsinks on to give you an idea.

Here is a link I used to try and reference my card revision


Unfortunately I am of need of my card to get a stable working system, so will be unable to send this to you. I can confirm that the rev 2.2 will fire up with a rev 2 Phase 5 Cyberstorm 060/PPC card.

Thanks again.

Looks like rev 2.4 is now available? Sorry my German is poor. From what I can deduce the building of this revision is now underway. SCSI now appears to be one of the new features built onto this revision.

Who is building the new Rev 2.4?
 
Yes, V2.4 is under test now. There will only be minor changes, like a connector for the reset signal used by the KickSmash board.
Except for testers, there are no builds available right now.

Other topic: are you able to burn the 16v8 GALs? I‘d like to try a change of U701 to address the problem of your WarpEngine.

@saft6luck Thanks for the reply. Look forward to seeing the outcome of the rev 2.4 tests.

I don’t have the tech or know how to burn GALS at the moment. Sorry.
