Few hours ago I bought a six gigabyte IBM hard
disk and 64 megabytes of sample RAM to my PSR
9000 and they work very well. The installation
was easy and I did it myself. At the moment I
am waiting for the 2.0 operating system.

I have heard that it is possible to convert X1
and KN5000/KN60000 styles to the PSR9000. The
idea of having Technics and Solton styles in
my PSR9000 sounds great. How is this possible?
It really really sounds amazing.

I have been looking for buying a carrying case
for my PSR9000 becuse then I could take the
keyboard with me to our summer cottage for
the summer. From where can I find a cheap but
still a good quality case for the keyboard
where I can carry the keyboard safely without
a single scratch?

Thank you!!!!!!!!

Given I am having some difficulty finding the correct SIMMs to use in my PSR 9000, you might beable to help me.

What was the specification of your RAM/SIMMs and who made it?

* 32MB
* 72 Pin
* EDO
* 60 ns
* Non-Parity
* etc.

I tried a pair of SIMMS with the above general spec. and the PSR would only recognize 16MB of the 64MB.

Thank you

Hello Frank!!!!!!

The specifications of my SIMMs are:

- 70ns
- 64bit
- 64mb
- sdram

Sorry. I don´t know who made them. I could not
find any mention about it. I think you should
try another pair of SIMMs. It is possible that
the SIMMs you have are damaged.

Good luck

Michael

Hello Frank,

at the unofficial PSR 8000 site I wrote a warning about 72pin EDO RAM. I also installed 64 MB EDO RAM and my PSR 9000 recognized only 16 MB (the same amount as yours). Fortunately I had in my computer a pair of old 32 MB 72 pin (non EDO) RAM, which was recognized without problems. To be quite sure, then I tried once again another pair of 32 MB EDO RAM and they also were not recognized (not at least 16 MB).
Therefore I assume, that the PSR 9000 has problems with the recognition of the EDO RAM and I would recommend you to use old non EDO RAM.

Hope this helps

Regards

Marek

P.S.: Micco, SDRAM are 168pin, they cannot be used in the PSR 9000.

Thanks for your response. I have contacted Yamaha Tech Support and while they are no longer suppling the RAM, they had some in stock and will send them out to me this week.

Thank you
