Don't know why, but here

ok, all parts arrived ...
But, again but, I don't manage to get any drive to work ...
Tryed with :
Amiga drive
Amiga gotek
PC drive with adapter (3 PCS alps)
Amiga drive doe's not spin at all, I think I don't hear any spining ...
Amiga gotek says to check the ribbon cable - maybe wrong
PC drive spind, led on the drive is on
@8 - nothing
@9 - nothing
no matter how I turn the switches both up or down
JP1 is closed, JP2 is closed, JP3 - I didn't touch
2 ROM on 27c512 ....
EDIT : OK wih no drive connected I got :
73,COPYRIGHT CBM DOS v10 1581,00,00
-
Have you checket the dip switches behind the drive ???
maybe it's not set on 8 ????
-
I have made your Multi speeder ....
BUt I have a problem ...
After turning the drive on i got a constant motor spinning ...
BOth leds light and stay on ...
Advices where to search ...
THe eprom is an at27c040, do I have to brick somthing ???
Looked for the jumpers you wrote on your git, but didn't find them ...
EPROMS
Du kannst ein EPROM-OTP 27c040 verwenden oder ein Flash-EPROM 29LV040.
Bitte achte darauf, dass der jeweilige Jumper JP5 oder JP6 gesetzt wird!
Ansonsten funktioniert das Umschalten der Banks nicht korrekt, da sich das PIN-Layout dieser EPROM-Typen leicht unterscheiden (PIN 1/PIN 32) -
I'm assembling this board, and have a question ....
Is it possible to put a custom kernel switcher with 8 ROM's like this one Bitte melde dich an, um diesen Link zu sehen. ????
Can you let us know 8 different DOS for the 1581


You are right, didn't take care that the ROM's strictly must be for 1581 ....
Tought that I can put any ROM in it

But I think that if you have the original and jiffy, you don't need any more rom ....

Well the best way in your case will be the arduino mega as ISP ...
But I recommend to buy a cheap one USB to ISP programmer ...
EDIT :
Here but it's in english ...
Bitte melde dich an, um dieses Medienelement zu sehen.
It's the same UNO and MEGA, just look for the pinout ....
DID you download the GUi version of avrdudess ???
Try to get one of this, it's cheap and will solve you a lot of hedache with programming ...

Just reload the .hex file, change the fuse, and try to reprogram the chip ....
Even did you try the erase button in xgecu to erase the chip ???
Do you have an USB to ISP programmer ??? to try to program it with avrdudess ???

OK, non did mention that in the transport the HDD could be damaged ...
Take the HDD out, and test it in some other computer ...
Use the mini tool partition program to test the surface of the HDD, if the HDD will be recognized by the programm ....
An HDD station would be nice to have ...

OK, it's all great, but you have to solve the progamming the rom's when they are onboard, soldered ....
It should be able to move/remove/add another rom when all is soldered ...
Via some pin headers or similar ....
-
Why didn't you put all SMD components .... like 0805 resistors and capacitors .... or even 1206 ....
Would be more nicer at all ....
But with this 29040 or 27040, soldered once or twice, and had to say that that was a challenge to solder .....
How will the programing take part with all SMD ???

A1200 gleich in der ersten Minute
This don't look like an A1200, no floppy at the joistick side .... even the F1-F12 are in 2 colors, by an A1200 they are all grey ....
Even the keyboard is upped by holders ....
It looks like an PC keyboard ....

Today soldered ...
Thie first Magic Formel didn't work ....
Now hoping that one of this will work ....
And an 1541 ROM adapter with ram ....
