Bavarese: none of those numbers match a known microcontroller to my knowledge. Might have to get it decapped to find out what it really is.

The C64 printer interfaces likely contain a small CPU or microcontroller and ROM(s) that can be fairly easily dumped.

Logitech relied on a number of custom ICs, manufactured by Zilog or Motorola according to the site http://www.tcocd.de/Pictures/Peripheral/in_mice.shtml, especially

330063-00 S1 (Motorola) - used in M-S28, M-S30, M-S35 mice
331021-2001 (Motorola) - used in M-S34, M-S35
331021-3001 (Motorola) - used in M-S30, M-S43, M-S38 MouseMan
331115-1001 S15.1 - used in M-S61, M-S35 mice

Is anything known about these chips - or the numbering scheme? The last part looks like a software revision...

--- On another note, the Wiesemann Type 9200 has a PHILIPS MAB8048HPS017 controller (guess it is a 8048 compatible), + a seperate EPROM. Guess i can read it - if i can obtain infos on the type.

Here is a list of 44 Logitech mouse MCUs from 1986 to 2003, taken from a half-defunct German site Mostly Logitech's internal numbering, though. I added my own PS/2 mouse, as well as info retrieved via FCC-ID.
In some cases, very detailed PCB photographs may be obtained from the FCC site. Logitech even printed the FCC ID directly on the circuit board (for some time).

After 1994, they were force to relocate manufacturing to China / Taiwan (and i believe they stopped marketing programmable mice and used less capable controllers).

I am curious what Motorola SC403127FN (1990), 42C40P1924 (Japan 1991) or SC88932P (Motorola, ADB Mouse M-AC13-4MD) controllers had inside.

In case it may be of interest, somebody has been hacking and dumping stuff from a TecToy "Mega Drive 4 Guitar Idol" console.

Cool!

New level of crazy for the EuroPC: A guy dumped the Schneider Keyboard MCU "Schneider ZC86115P" which turns out to be a mask programmed MC6805U2. Using Info from Sean Riddle he dumped the chip and replaced it with a MC68705U3 that is mentioned in the schematics as an option. He's posted the ROM code as well.

Nice, can you reupload this? That forum requires registration to download files.

TeamE's been busy again with stuff I sent him - I can't thank him enough!

One of the highlights will take a little time as an adapter is needed to dump all the relevant stuff - I finally got hold of an Olivetti Quaderno, a tiny subnotebook that had a special feature - you could activate its harddisk without booting the machine and use it like a dictaphone to record audio using transport keys (play, stop, forward etc) on the lid. I'll make a proper post once I've got all the files.
The second goodie is an ultra rare portable machine that was developed by the same company as the ITT3030 and the Alphatronic P2/P3, the SKS Nano 2500 (actually model 2515). No boot floppies have turned up for this CP/M machine, but me and another owner hope that including it in MAME and prodding it with the debugger might help in generating one from TA/ITT ones. Again, this beauty will get a post of its own once I have all the files and some nice photos.

The Sharp Fontwriter FW-600 uses a much smaller screen than the FW-700 RB's already taken a stab at, and this one has an English keyboard.

Files as usual on the FTP and here.

Keyboards ... my old nemesis smile I got some spare mainboards today, three Commodore (PC 10-III and PC 30/PC40-III), and one with an Ericsson sticker.

Before I issue a pull request, I'd like to find out what machine it comes from (anyone? Edstrom?) ... there are two Ericsson models in the PC driver (with the portable one working), but this one is different again. I hope the ROM is complete, as there's an empty socket next to the existing chip.

With the mainboard came a little memory board

Dropping the ROM into our PC driver produces that old chestnut, keyboard error - press any key.

Other graphics cards produce varying, but less convincing results smile
