Begging for ROMS

The Yamaha SY99 is a synthesiser combining frequency modulation synthesis (branded as Advanced FM) and sample-based synthesis (branded as Advanced Wave Memory 2) and the direct successor to Yamaha's SY77/TG77

By looking at one of my pics (taken while 'servicing' my SY99) I just found out that my CPU is the PROM version:

More interestingly is that it is the CP10 version that I assumed to mean 10Mhz. Maybe the CP10 version is fine to use with the 24MHz xtal :)

Miks,

Yes - that picture is definitely worth a thousand words, confirming the CP10 will work. Just waiting for Brian's CPU to arrive to test ... since it's burned from the dump of your CPU's code, optimism is high.

I've already confirmed the EPROM portion of the 1.57 firmware, so if Brian's burn of your data is confirmed -- it looks like we're a go without having to rely on the 'unicorn' CP12.

BTW - No, I can't read the masked version CPU

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 !

So as long as the CPU is socketed (PLCC84), any SY99 should be upgradeable all the way to 1.57. I think if the firmware is older than 1.40 you might want/have to do the other 3 EPROM's as well, but I believe Miks has that data as well.

Good job, mates!

Manny

PS Gonna keep bugging Musitronics for the 5MB expansion... that would be 10MB fully loaded with a WaveBlade !
PPS Brian, love the Datablade, replaced 6 MCD64 Cards.

That's great news, and I am glad you achieved what you wanted. It shows what still can be done with this range of older synths with a bit of detective work.

I've been following this thread quietly as I dont have a need for this, but it has still been very interesting to follow. :)

WOOW - this IS indeed great news! (Y) ((i)) ((i))

Well done, Brian & Manny - great outcome! :D

So where can you get a functioning blank HD6475328CP10 chip from now?
Wasn't that the biggest obstacle, sourcing the chips?
I had little doubt that the upgrade would work with a correct blank chip, my understanding was that sourcing the chip was the problem.

And to think I can going to toss those CPUs!

Mine came from Aliexpress a few years back. A recent search there came up with 4 vendors but the risk can be high.

This one can't even get the "H8" part correct - see photo :!:

Does anyone have the V1.30 sequencer ROM XJ616D00? http://www.yamahaforums.co.uk/forum/viewtopic.php?t=190

Jepp - wait a moment, I'll dig for it on my other computer - I'll be back! :wink:

Edit: took me a while to find it - but what's puzzling me is a text file saying IC 101 (Sequencer ROM) is Version 1.2 instead of 1.3 8O

Is there a way to find out what Sequencer ROM version really lives in my SY99? Perhaps via the built-in test program... :?:

The stuff I've been testing with I've been getting off eBay. Prices are all over the place, but if you just need one $50 (from a seemingly reliable vendor here in the states) is less than Yamaha charged.

Thanks Sonus - Main ROM is 1.57, Seq. ROM is 1.20 8O

Could it be the '1.30' is a typo...?
