Amiga Hardware Issues and discussion / Re: DKB Cobra 030@28 - any good?
« Last post by Boing-ball on February 25, 2026, 01:00:08 PM »
Holy Thread resurrection Batman!  ;D

The one and only 030 classic accelerator was and still is the Phase 5 1230. 50mhz 030 upto 128MB RAM. Then buy and add a SCSI 2 add on with DMA and another 128MB RAM. Maprom functionality etc..

started with a 1202 around 2016 then a DKB Cobra 40Mhz card. Bought locally it was a good solid card with FPU. Luckily it was the updated rom version.

Around 2020 I was interested in the icomp ACA cards for their SYSInfo CPU and RAM performance. Mainly because that was the trend in forums at the time.

IDEFix scsi patch rapidly enhanced IDE = HDD CF transfer times and also the Cobra rom has a serious bottleneck in that department, giving around 800kbs IDE speed while ACA cards were 2.2Mbs up to 4.4Mbs with IDEFix. The IDEFix hardware shows even greater figures up to 6-8Mbs.

It's hype though and I was caught up in the culture of it.

  Yup..  20 yrs late too.   My first accelerator too although I first started with their DKB 1202 board.  (https://amiga.resource.cx/exp/dkb1202).  Simple memory, FPU and RTC upgrade.  Ahh those were the days.  8MB and you though you were a KING!

 FWIW I had nothing but good times with mine!  I had the accompanying Ferret SCSI board (https://amiga.resource.cx/exp/ferret) and it always worked GREAT! I used it with my external SCSI CD-ROM, Connor DAT drive (used AMI-Back, Diavolo and Quarterback) and a random SCSI flatbed or two.

  I seem to remember at some point having some technical issues, mailing it back to DKB, and corresponded with Dean Brown during the repair process.

20 years late, but you may still be interested.  The DKB Cobra 030 was my first accelerator.  I'm not sure if it was a 28MHz or 33MHz, but whichever it was, it worked well for me.  I later went through many other accelerators, but the DKB was the most reliable along with an Apollo 1240.

Amiga Magazines / Reminder: Amiga38 DVD released
« Last post by AndreasM on February 24, 2026, 02:35:08 PM »
It took a while, but the Amiga 38 DVD has finally been released to coincide with the Amiga 40 anniversary.

We'd like to remind you about the Amiga 38 DVD, which is intended as a small token of support for the organizers of the Amiga event.

This is for anyone who missed the presentations or would like to watch them again at their leisure.

Furthermore, some remaining Amiga 40 event merchandise is still available at amigashop.org.

Order Amiga38 DVD now: https://www.amigashop.org/product_info.php?products_id=474
Order Amiga37 & 38 DVD Bundle now: https://www.amigashop.org/product_info.php?products_id=475
Order Amiga Event Merchandising now: https://www.amigashop.org/index.php?cPath=53

The Amiga38 DVDs release is actually two (2) pressed data DVD9 discs with the following content:

* Amiga38 Documentary
* Interview with Dave Haynie (Amiga34)
* Amiga38 Panel AEON - Trevor Dickinson
* Amiga38 Panel Demoscene - Andre Kudra
* Amiga38 Panel - AmigaOS 3.2 - Camilla Boemann
* Amiga38 Panel Pistorm - Michael Schulz
* Audio Interview with Dave Haynie (Amiga34)
* Audio Interview with Markus (Amiga34)

Please note: These are data DVDs with video files.

Almost all of the proceeds go to the organiser of the Amiga Event, in order to support the financing of future events more easily.
The same applies to the Amiga 40 event merchandise.

A600GS & A1200NG / Re: AmiBrowser & broken JavaScript keyboard events
« Last post by broadblues on February 24, 2026, 11:35:19 AM »
OK added a extra layer of debug:

  END doesn't report at all

Doesn't generate a RawKey event at all so that will be why.

    PageUp reports as ScrollLock, too
    PageDown doesn't report at all

I have this the other way round PAGEDOWN generates RawKey 95 (ie it's mapped to scroll lock AKA known as HELP in amiga keyboard context on OS4 atleast) PAGEUP emits no event

    ScrollLock doesn't report at all

Doesn't emit a rawkey event.

    PRINT doesn't report at all

Also no RawKey event,


F11 Is mapped to RawKey 13 (backslash)

HOME and INSERT are mapped to 102 103 ie Left and Rght Amiga.


So these "errors"  the result of the default keyboard emulation.

```
    NumPad9 reports as NumPad8        -  SHOULD BE IN NEXT RELEASE FIXED REVERSED CODE order in table
    NumPad8 reports as ScrollLock        - FIXED ditto
...

```
    F11 reports as Backslash                  - my test in cefclient shows correct hardware code in table,
    INSERT reports as MetaLeft             - my test in cefclient shows correct hardware code in table,
    HOME reports as MetaRight             -  my test in cefclient shows correct hardware code in table,
    END doesn't report at all
    PageUp reports as ScrollLock, too
    PageDown doesn't report at all
    ScrollLock doesn't report at all
    PRINT doesn't report at all
```

These are  more complex the codes in the table are correct based on the key events generated on the linux side, it may be there is some translation happening between the linux keyboard and the rawkey emitted inside the emulation.

My table originally mapped RawKeys (sent by MKShare from AmigaOS4) to linux uinput events, it's 99% accurate insofar as the correct key events occure on the linux side when an amigaos4 key is pressed. So I filled in the entries in reverse to create the newtranslation of rawkey to lowlevl hardware key.

I'll  have to add a extra debug layer to see what RawKey I get inside the AmiBench layer. Perhaps these spacial keys have been traslated by AmiBerry to look more like an amiga keyboard.

```
    CapsLock doesn't seem to invoke "OnKeyDown" and "OnKeyUp" but with every keypress, it switches between the two (while "OnKeyPress" being with "OnKeyDown")
```
I'll bet RawKey events are only being created on transitions of the key state here as it;s a locking key.. tempted to blame input device for that one (without hard evidence :-))

```
ESC closes the browser, even if event.preventDefault() is called (but I guess that's a bit of another issue)
```

This key is intercepted by MUI before it can be sent to the browser engine, it may r may not be possible to listen for that javascript call later on.

After fitting a D.K. Video Crisper RGB video buffer, which I hear is 15khz only; to the RGB port of my A1200 OS 3.9, before a Scandex doubler, I have no video signal; HDD activity stops, about when WB is loaded in startup.

I am using an external Scandex doubler to TFT monitor for both CGA and VGA modes. I tried a second Scandex and no change.

The Early boot menu shows but invisible mouse pointer. Floppy boot is the same.

From this thread: https://forum.amiga.org/index.php?topic=73237.0 I followed Oldsmobile Mikes' suggestion of swapping the ROM's for new ones and Accelerator card and PSU. Also disconnected mouse and Joystick. No Change unfortunately.  ???

Suggestions Welcome. TIA.

Hi,

Welcome to the forum!

That is a nice collection for sure! Please let us know how it goes with the 2500 and the monitor. The computer might have some neat upgrades under the hood. 8) And.. nice list of games there!
