Re: Proud owner of new WaveBlade. Need help with SY.factory not working.

Good to hear you got this cleared up :) The programmer firmware version shouldn't be an issue with sy.factory as nothing has changed regarding the connection. It's mostly code clean-ups and trivial stuff. All I can suggest is that to make sure the correct COM port is selected and use the 480600 rate...

Re: Retro Gaming with the Roland MT32 . . .

Every now and again I put the stuff on the bay as a sort of advertisement to say that it exists. There are long-time SY / TG owners out there that have only recently discovered the expansions are available.

Re: Retro Gaming with the Roland MT32 . . .

Thanks for posting that video para, the MT sounds a lot better than I imagined. I found a service manual for the MT that has a test routine that may be useful.

I don't see a download section for Roland so I've put the file here:

Re: Yamaha SY85 Sound Disks.

Here's an archive of 60+ SY85 disk images. Some are patches only and others have sample data. I've no details about most of them so you'll need to just try them out and see what you like.

Re: Begging for ROMS

Manny, thanks for the hint - will try bending the pins. Need to find out wich ones are exactly the ones for the wheels - is it documented somewhere? AN0, AN1, AN2 on the right-side of the CPU read the wheel positions: http://sector101.co.uk/external/forums/SY99_CPU.jpg It's probably best to adjust ...

Re: reface cp hands-on review

I'm very happy to hear Dusty is still about . . . He was MASSIVELY helpful to me some years ago on the subject of FW upgrades for the SY85. This takes me back to 1994 when I bought a new TG300. There was some strange bug with the LFO where a slow Sine setting on the filter would jump from time to t...

Re: Begging for ROMS

Gentlemen, awesome news, we have success! I received Brian's burn of Mik's CPU data to the HD6475328CP10 Chip, combined it with the EPROM data of Mik's that I burned & tested previously - and voila' - SY99 upgraded from 1.40 to 1.57 ! And to think I can going to toss those CPUs! So where can you ge...

Re: Begging for ROMS

By looking at one of my pics (taken while 'servicing' my SY99) I just found out that my CPU is the PROM version: http://www.yamahaforums.co.uk/forum/download/file.php?id=409&mode=view See lower right corner - it's a 6475328 type CPU... More interestingly is that it is the CP10 version that I assume...

Re: Begging for ROMS

That is the MaskROM version of the 532 where Hitachi have put the CPU code into the die during fabrication. 64 3 5328 MaskROM Version 64 7 5328 PROM Version See if you can extract the code from this. I tried with my SY85 80pin QFP CPU but failed, I don't know if I had it wired wrong or MaskROM CPUs ...

Re: Begging for ROMS

Hold fire on the CP10 version. The datasheet says that (at the time of writing) 10MHz was the fastest model available.

Maximum clock rate: 10MHz (oscillator frequency: 20MHz)

The Xtal in the SY99 is 24Mhz so the later CP12 version would make sense, assuming "12" means 12Mhz.

Re: Begging for ROMS

I remember trying to read the code from my TG500's CPU ROM area and it was successful. The TG500 uses the same IC as your 1.40 and 1.57 SY99 CPUs so it would be possible to get the 1.57 code out of the your CPU and use it to upgrade other SY99s. Some SY99 units may have the SMD version of the IC so ...

Re: SY55 Memory Card without battery lost presets

Hi,

Sorry, no magic will recover your sounds. Once the battery was removed during the change-over all the data was lost.
