R7565 Beta Core for V1200 : We Need Your Feedback

Hi guys,
 
We have been testing core 7565 for V1200 for some weeks now and noticed we need more feedback before releasing it as a stable core.
 
Biggest change in that core is on the ChipRAM speed and we need to make sure it does work on all A1200 motherboards giving people same level of stability and without hickups on CIAs (mouse, keyboard, etc.).
 
For that, we would be glad if you could test that core and report with details of your A1200 motherboard :
  * Motherboard revision
  * Recapped motherboard : yes/no
  * Recapped PSU or new one : yes/no
  * Timing fix : yes/no
  * If yes : which fix ( based on EXTERNAL LINK )
  * Any other useful detail regarding the issue you face (mouse type, replaced keyboard membrane, etc.)
 
Only report if you have all those details otherwise your feedback won't help us.
 
Core is here :
EXTERNAL LINK   
 
Happy testing ! :)

Ok just tested before your request on my A1200:
    Motherboard rev 2B Not Recapped
    Original black 25W 3A PSU not recapped
    Timig fix NO because the motherboard have no E123C and E123C and no E122C and E121C
    Original Commodore Amiga 1200 Mouse 12/93
    Kickstart 3.1 instead of the original 3.0 and RTC on A1200 clock port.
    The core run ok but is unstable after a bit like said on slack with problems typing with the keyboard where the keys repeat the same letters several times.
   
    Bustest runs ok the first time showing 7,1 as bandwidth on all chip operations. But when became instable reports very different numbers.
    I noticed that clicking the floppy drive also tends to desynchronize.
 
Instead on 7389B core all perfect.
   
Bye.

No problems at all with my recapped a1200 with new psu and board rev 1D4
  I tested with a remapped 3.1.4 rom (no rtc no timing fix)
System run stable after whdload, Quake, sysinfo, ecc.. . Bustest reports 7.1 on all values before and after, floppy clicks are regular and keyboard works perfectly

Hi Renaud, after the first cold reboot I got instant problems on my machine - I can't really use the Amiga because of the mouse and keyboard hick ups.

  *fast and often diskdrive clicking
  *Mouse double click dosen't work reliably
  *Seconds are jumping in DOpus - No RTC clock - (get time over net)
  *Keyboard error - It's not possible to write one correct word

Config:
  *Motherboard revision: 2b
  * Recapped motherboard : yes
  * Recapped PSU or new one : new one - EOS VLT60-3000
  * Timing fix : yes
  * If yes : 121C,122C,123C, 125C removed
  * Any other useful detail regarding the issue you face
    *Edu PS2 Mouse Adapter with an 15 year old wirless PS2 mouse
    *new Keyboard membrane
    *no RTC Clock
    *Soundcard MelodyPro
    *D520 Flickerfixer

With the last 2x12 Gold Core is the Amiga fast and stable.

Hi guys / Renaud,
 
System does not boot for me either, Vampire boot logo and the "blip" sound...then it doesn't go any further.
 
 
    * Motherboard revision: 2B
    * Recapped motherboard : yes
    * Recapped PSU or new one : ATX
    * Timing fix : No
    * RTC : No
    * EXTRAS: Indivision Rapid Road

Everything works fine on offical 2.12 core.
 
Regards, Pete.

Some new whdload troubles (Example: desert dream demo crash amigaos on exit)

Motherboard revision:    2B
Recapped motherboard:    YES
Recaooed PSU or new one: YES
Timming fix:            NO

  Interesting - a working 2b. ;) Thanks for the Info. Which PSU do you use? Have you checked the mobo on the backside for the timingfixes?

Thanks :)

  Hi, here are som pics of my setup:
 
  A1200 motherboard with a500 keyboard: EXTERNAL LINK 
  A1200 running whdload demo with beta core:

  A1200 bustest chip after running some demos on whdload:

  Bench PSU locked @5.00V:

  If you need more information, I will gladly send it to you. I can also connect my oscilloscope or logic analyzer on the bus I can also do it. (200mhz 2ch with trigger osc and 1ghz 16ch logic analyzer available)

Edit: No timmig fix on motherboard, confirmed.
