In the Aurora manual there is a nice lovely section on the mouse port numbering - but it has left me even more confused than ever!
I understand the IDC header numbering goes odd down one side of the connector and even down the other side - so the idc cable would then be 1-2-3-4-5-6 and so on, (only first 8 connected)
BUT - when it gets to the 9 pin D shell - the numbering for Amiga and Atari mouse don't seem to match completely with what I've seen on the various forums for each mouse type.
I see on Marcels site that you can switch between Atari and Amiga by just swapping one and 3 over from the 9 pin perspective (which is effectively swapping 1 and 5 from the Aurora connector?)
Does anyone know if that will also work for the cocolino Mouse adaptor that converts PS/2 mouse to Amiga format?

Re: Confusion over Aurora Mouse port numbering
Keep in mind that conventional D-connectors existed before the idea was thought up of making IDC versions that could connect to IDC cable. Hence the numbering gets a bit confusing.
Atari, Amiga, Acorn and some early PC mice are ‘bus’ mice. Two TTL digital lines are encoded with square waves for each direction, (so two lines for the X direction, and two lines for the Y direction) plus the button inputs and +5V and 0V/GND.
But the various different manufacturers were not consistent in their pin allocation. With the Atari and Amiga, just two signals need swapping around to change from the Atari pin-out to the Amiga pin-out or vice-a-versa.
The same would apply to any standards converter that goes from PS/2 or USB to an Atari pin-out or to Amiga pin-out if you wanted to use said converter on a different system from the original intended system.

Standby alert
“There are four lights!”
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer in Somerset later in the year
QL, Falcon, Atari 520STFM, Atari 1040STE, more PC's than I care to count and an assortment of 8 bit micros (Sinclair and Acorn)(nearly forgot the Psion's)

Re: Confusion over Aurora Mouse port numbering
Looks like it's pins 1 and 4 that need to be swapped for Amiga Mouse - which would be 1 and 7 on the IDC cable H and V movement swapped for Amiga
so straight through IDC is for Atari - not Amiga as documented in the Aurora manual...

Re: Confusion over Aurora Mouse port numbering
Hi,
I seemed to remember there was problems with the Aurora manual which did not match the I/O connectors, I think there is mistake on the serial port as well.
Did you get the Aurora board working?

Nearly there - I have a backplane to solder up, and a modified qubide board to put together (extra IDE channels)Derek_Stewart wrote:Hi,

I also need to finish up my PIC PS/2 to IPC keyboard interface - plenty on the go
