These A4000D boards are part of the third batch which I did to test the ENIG coating. They are based on Acill's A4000D board and have the following upgrades integrated:
  • Markings added for jumper, chipset, sockets, logic, all resistors, capacities etc.
  • Drill holes are changed to real holes instead of vias, L500 and many, many more small fixes applied
  • 2MB Chipram on the PCB (74F841 not needed anymore)
  • BIGROM integrated (see A4000T), allows for 1MB Kickstart, compatible with original ROMs; can be deleted via resistors
  • RAM Extension integrated: up to 112MB Fastram
    SIMM size configurable via jumper: 1MB up to 64MB SIMMs, max. 112MB Fastram; can be deleted via resistors
  • RAM BANK0 und BANK2 can take double sided modules now, e.g. 2x32MB (= 4x16MB) or 1x128MB (= 2x64MB)
  • 8MB Chipmem options are removed -> saves 2 ICs and removes 2 useless jumpers
  • Kickrom with 42 Pins and integrated Kickstart switch
  • RTC Diode fix integrated, 2032 batterie socket + diode
  • Dedicated NMI and power up RESET connectors
  • Useless "Option"-jumpers removed (1x 74HCT166 not needed anymore)
  • Delay-line with 14 pins or 8-pin SMD version
  • 4-pin fan connectors: 2x12V, 1x5V
  • H- und V-sync buffer for the 23-pin connector; can be deleted
  • Power supply via jumper for IDE DoMs or CF adapters
  • Side holes for the stacked connector are fixed to work with up-to-date connectors from e.g. mouser (old style still works) - similar for cinch connectors
It took me ~8h to build one board, just using the markings on the board. Normal A4000D and/or A4000Cr build instructions also work fine.
The board is tested with BFG9060 + 112MB Fastram, original A3400 (68030) and Z3660.
The following Zorro cards are tested as reference: ZZ9000, Buddha IDE, Deneb, XSurf 100 with RR, Piccolo SD64 und Re4091.

There are still 6 4 1 PCBs available.

PCBs are available on request as I regularly order new PCBs for my developments.

One PCB is 192€ + shipping via DHL, for Germany included, most EU countries 9,50€, all others on request.

Payment possible via Paypal F&F or in EU also via IBAN.

Also part of the delivery are the files for the GALs, a manual, the BOM for the missing parts and a Mouser basket for all parts which are available there.

If interested, I can include the chipram for 16€ and/or 2 used, but fully working MX29F1615 flash chips (-> 4x 1MB Kickstart) with e.g. DiagRom for 5€.

PCB arrived today after a 2 week journey to New Zealand. Very well packed / damage free and prompt shipping. Thanks. Feedback left.

Got my new A4K board, the old board is ready to harvest, Mouser BOM order and tbtorro's 200 pin Connectors arrived. Now to find sometime time.

Declaring interest in one, with Chipram and flash chips. Been trying to fix up my OG board but can’t get Z-III working so time to take the plunge and rebuild!

PM incoming.

I really like seeing progress on getting updates done to my boards. I'd like it even more if the official repo got changes added back into it as well. It's a shame all the progress isn't getting back in with a few exceptions. I know of several branches all working independent now. This wasn't my original intention on making everything public.

That's right but it also needs time to update and test these changes. If you want to participate there, you are free to join.

There will be a version soon, which you can get to review and even update your repo.

But I don't think this is the right way to communicate your dislikes. You know where to catch me. And personal communication should do the trick.

I'd love to, but currently I am away on work travel. I can still check in some though. I also replied to the discord message you sent me.
