"One computer Ghuru I talked with in Baltimore said it appeared as if the HDM was nothing more than a miniature hard drive that fits most notebook computers. The only difference was the external selection switch which allows you to select the individual allocation slots on the hard drive. He said they sell for well under $100 at most independent computer stores."

I think you will find the HDM is a little more complex than this. It sure looks like is uses a notebook hard disc which indeed can be had for under $100, but Floppy disc interface used by PCs/Keyboards is NOT the same as a hard disc, and the disc directory structure, whilst identical in concept (FAT), is not identical in implementation. The HDM presents "I'm a floppy disc" to the keyboard whilst presenting "I'm a PC" to the hard disc; the switches select the selction of the hard disc that is being used to hold 1 Floppy Discs worth of data. This is quite a neat trick and is much more than "just a switch".

Beaky: I've wondered about the "flash ram chip swap" as well; however if the flash is embedded into the processor then we are noodled. Also it depends on where the flash exists in the memory map (if thats how it is done) or how it is accessed (i.e. is it accessed purely as another storage device). To be honest I figure it's a no-no.

Is there a part number on the existing chip?

I'll probably go the HDM route and not the flash rom route. The only advantage of the flash rom route is saving registrations and it would be cheaper, but it might not work, and I'm nervous about tinkering with the keyboard like that.

After reading from two happy PSR2000 customers, I am convinced, and I'm going to purchase this thing.

Good for you Larry

Let me know how it all goes for you.

Thanx

I received another reply from a German PSR2000 owner who is happy with the HDM in his machine.

Hi Beakybird

Could you tell me what the German forum address is. I think I had it but can't find it now.

Thanx

Hi Larry
I'm interested in what you're working on, also. Increasing the flash ROM sounds great, but I know I can't do it.
I like the idea of the HDM, too. I might get one if you have a good experience with it. One thing I want to point out. Since HDM essentially acts like 99 floppies you have to consider how you "load" them. You have to use the push button device to choose the floppy. So, if you're on number 01, and you want style that's on 87, you have to push the button 87 times? That doesn't sound too good. Maybe I don't have a clear understanding of how it works, though.

Hi Tom and Larry

My guess is (I hope) that if you are on 01 and want to go to 87 you can go backwards 01,100,99,98.... This is how it works on a Lowrey organ and the cheaper Yamaha's. Also, on a lot of instruments, if you press them both together they automatically go back to 00, or 01. Also, I would think you could go up one at a time, or hold the button down to go quickly to a distant number.

I'd like to know more about this flash rom chip. I wonder who would have the answer for that one?

Scott Langholff

I was just thinking, maybe one of the other Yamaha keyboards has a larger flash rom chip, and may have the same 'plug-in'? Tyros, 8K, 9K ??

It's interesting that I spoke with my friend Marina at worship services today. She is the friend who called the fellow in the Ukraine who is listed at the 2av.com website. She asked for his email address. It is the same address as the one at the 2av.com website. I was wondering why he never returns emails, and I thought perhaps he had a different email address. No one I know has ever been returned an email.

My friend Marina told me that when she spoke to this man, Vasilio or something, for a few minutes to get his email address, he said that he speaks absolutely no English whatsoever. Thus, no return emails.
