fts=favourite track selection. You can store your favourite tracks for a lot of cd's. Player stores them and recogises the cd next time. In the 650 a separate controller is used to handle this.

As for the motorola way, had a quick look in the service manual of the cd880, which uses 68hc11. Two problems: protocol is different, not i2c towards keys and it's a controller with onboard rom. Expensive player anyway. Not shure if a player exists with external rom; dead end.

Actually you can select e.g. track 9 in stop position on any player. Press next nine times and then hit play. The message to the mab on the main pcb should be the same as if hitting button 9 and then play. So you probably don't need a player with a keypad for numbers (?).

And I don't think you need a player with exactly that pcb. Just a player with i2c/i2d communication from the right time (so with cdm2 or cdm4). So with a curved hole in the cd drawer.

Have a look around where you live (second hand shops) with what you can find and then post some numbers here. Good chance somebody here has the servicemanual and knows if it's good or not.

Yes, that idea occurred to me too. There is only one Philips CD player available, a CD104. Sounds like an early model and might be okay. Couldn't find an online sevice manual to confirm. Do you or any readers have access to a manual to check the pcb layout?
If it's close to the CD640 (or CD650 or CD660) then it's the one I need to further my work.

104 is older, 14 bit machine with cdm0 or 1. But it does use only two MAB84XX controllers with i2c/i2d bus. Apart from them, there's a serial to parallel chip on the bus (cmos hef4094).

This will be more difficult to keep running, as the pbc's give problems (search here). Allthough older, it might be enough for your needs. Maybe if it's really cheap.

As for the service manual, send me a pm

Actually got one of those, and a b&o cd-x which is based on the 104.

I've been reading reviews of the CD104 on the net, and they are all good. There seems to be quite a lot of nostalgia for the old kit.
What is the hef4094 doing in that machine? Will it still work if I were to unhook that chip from the I2C bus?
I know about the thro-hole plating problem, that doesn't bother me. This might be the way to go, get the CD104 for experimentation!
I've sent you a quick e-mail from this website.

Andy! Please would you be kind enough to upload the CD160 PCB layout to the yourfilelink website?
I'm getting this model soon, and it would be a great help!

Guido, interesting mention of this chip: does a HEF4094 allow us to make a discrete DAC?

It is a port expander.

Too bad. I would like to know if there are chips readily availaible to sort a series and bus feed to a parallel bit/by/bit schema. I understand from schematics like the TDA1541 that such a device must be called something like a shift register. . . because the (active) divider does the actual current sourcing.

Forum search engine. Term 'Discrete DAC'.

Default MAB8441 COMMAND PROTOCOL

I am surprised that some people need the same protocol that i need.
I work arround this because i want to make an upgrade kit for old cdm4 and use the cdpro2 from philips
now it's impossible to obtain any information about this protocol from philips
So i've buy an eagle I2C analyser and i've check the data command for the cdm4
There's a lot of things that a don't understand, but i've just understand the time that is running.
Does somebody have made some progress in that ??
