And, it was made by Mitsumi Elect. like the Amiga 3000 one, not NEC.

We (on the hungarian thread) almost gave up the amiga mouse -> neos mouse + boxsoft way of mouse connecting ...

We would like to connect PC mouses to the EP now. If we can, wireless ones, too ... :)

Zozo is thinking about extending the boxsoft circuit with a PS/2 -> NEOS converter circuit,

and I am thinking about a microcontroller what could connect everything to the EP in a boxsoft's converter compatible way,

multi button joysticks, sega megadrive controllers, PS/2 mouses and even USB mouses ... and USB mouses can be wireless ... :)

I've mid-read already that thread(google translator...). That are good news!

-------------------
At the back of the mouse card is a TA7533F.

Yes, the Neous mouse which are used with the BoxSoft interface using same protocol with the MSX mouses.
Then I found PS/2 -> MSX adapter, very simple circuit with one PIC microcontroller.
I think will be very simple project build on same PCB this adapter with Boxsoft interface then we will got a PS/2 mouse to Enterprise interface which are compatible with the old Boxsoft-Neos package.

Yes Zozo, it's the same mouse, at the backside is the a/d converter, a smd TA7533F.

I think the MB88201 is the controller chip(programmed) that changes from mouse to joystick behaviour. And could be who do the protocol, so an Amiga to MSX converter probably needs that chip, preprogrammed.....bad news.

I have an Amiga trackball connected to the internals of a striped USB Mouse(not optical). The Amiga mouses(Atari type) are very simplistic, as they give directly the movement of the disks-optocoupler pairs to the sub-d pins.

---------------------------------------------------
PS/2 to MSX!

I have a tactile surface Mouse from an old laptop PC....

Here is a page describing  ps/2 and Amiga protocol converters to MSX mouse.

---------------------

Attached below are the schematics of a MSX Mouse from Phillips. the same preprogrammed MB88201 microcontroller but few more components.

Observe the pinout of the sub-d connector, 8 is STOROBE, +5 is on 5, ground is on 9, Left sw is at 6 and Right sw is at 7. Too much different to the Boxsoft mouse.

According to this page STOROBE is necessary  for a MSX mouse  as the joystick port acts as a serial port(?)

Is the Boxsoft a re-re-modified mouse?

Viewing the schematics: convert Neos mouse (MSX like) to Amiga: remove wires from the Left/Right/Up/Down outputs of controller then connect these to the XA/XB/YA/YB inputs (output from the sensors). The controller totaly not used in Amiga mode.
When opened the Amiga mode Neos then connected the wires to the controller input pins?

Then I think just needed to put back these to the connector. Because the controller not used then possible it is contain the original program. Probably lot of original Neos mouse are unsold then these converted to Amiga by the simple wire replacement?

I don't have the modified Neos mouse I only extracted the pictures HI-res from that web. The Amiga mouses are simplistic and the computer does all the work, so here our Boxsoft Neos mouse does it by a micro controller. But is some different in its pinout than a MSX mouse.

For the strobe signal used one wire from the serial port. It is connected by jack plug to the main adapter. When it is inserted then Mouse mode, if not inserted the Joystick mode can be used.

Yes it is a C64 version, I think some wires reordered. But the communication protocol same with the MSX. Will be interesting found MSX one and open it...

I will measure my mouse wires, and write down the pinout with wire colors.

Which Neos you have? You wrote you bought one from Amazon.

I "only" have the UNmodified one of the last two pictures in this post.


--------------

On one web page they warn to not connect an Amiga mouse to a MSX mouse port, as the +5 pin is on the wrong one... you can fire "some" the MSX computer...

It can be interesting to extract the firmware of the MB88201, only 512 bytes(or 1k x 4bits) according to its datasheet.

I will document my mouse wiring and you compare on your mouse.

Yes, will be interesting but it is a Mask ROM. Programed in the factory during the production, not with a external device :-(
