I'm in the process of purchasing an FX-20 and am wondering what options are available for data storage. I don't know if the current owner has any RP1 data packs and I'm sure it doesn't come with an MDR1. I have an HS-8 with an MDR3 (which is MIDI). I know the FX-20 is not a MIDI instrument, but can the MDR3 be hooked up to it?</P>
You've already answered one of your questions - sorry, MDR 2,3 or 4 cannot be used. RP1/MDR1 and its product specific disks will not be easy to find given they are now over 20 years old. Best advice I can give you is to check Ebay or similarunder "Yamaha Electone" and see what crops up.</P>
Congratulations on the FX-20 ...please share some photos and sound
files when you can. There is a local FX-20 for sale and I am
tempted. Not sure where I would put that ... but tempted.
I bui;ld a MIDI convertor fpr the FX and FS organs. I currently need some metal backpanels to build more right now. I have toyed with making a reg pack that can store many times what an RP1 can, but have no way to make the necessary plastic cases. I have also modified one user's MDR1 to use both the original and the 3.5 inch floppies... It is tricky, but I also have even used a 5.25 inch floppy connected to an MDR1... </P>
I am kind of a focal point for technical help on these organs should you need it, so keep my Email address should you need help.</P>
I've been in possession of my FX-20 for three weeks now. What a fantastic sounding beast this thing is. It absolutely destroys my HS-8 in every aspect except programmability. </P>
Anyway, I have had an opportunity to pull off the small metal plate on the top-right corner of the back of the instrument and unfortunately, the MDR-1 connector is not present. So, my data storage options are extremely limited. It's really unfortunate that Yamaha did not include the "CASSETTE IN/OUT" feature on the F series. As slow and clumsy as this feature was, the ability to store registrations on analog tape would be a Godsend for me right now.</P>
The metal plate did not have to come off to see if you had the IFB kit... The connector, if present, is mounted on a replacement plate.</P>
Do you have some RP-1 reg packs? The reg packs have a 16Kbit static CMOS ram chip in them. The run from a Zener regulator in each pack that regulates 12 volts down to 5. There is a single Lithium cell in the packs to back up the contents. The pack has protection resistors in the address and data lines to protect against static discharges. The connector of the reg packs has two longer pins to connect the power before the logic signals. The 12 volts sent to the pack is gated on the SC board within the organ when accessing the pack. The connector onthe packs has Metric spacing.</P>

I hadan RP-1 back in the 1980s when I owned an MR-700 and competed on the FX-20 in the Electone Festivals, but I traded it in with the MR-700 when I bought my HS-8. Who would have ever thought that I'd own an FX-20 twenty-one years later? I have four RP-3s and one RP-5 for my HS-8. I don't suppose there isa way that the RP-3 or 5 could be manipulated to work with the FX-20???</P>

Why bother with the plastic case? I have torn my RP-3s apart and have inserted just the card into the slot and they work fine. </P>
As far as the "psycho" on ebay that wants a ridiculous amount of money for those RP-1s, he can choke on them as far as I'm concerned. I've already been "warned" by ebay for offering him $50 for the entire lot! LOL!</P>

One needs some form of a case as the RP1's have a write protect breakout piece. Without holding the microswitch up by the case, one can't write to the card.
Ok Fred, I think I have tracked down an RP-1. The current owner believes the lithium battery is dead. I have read the other thread about replacing the lithium cell and it is well within my skills to do so.</P>
Problem is, I have searched the online retailers mentioned in that thread and neither is showing the part number CR2430-ST. Is this cell no longer in production?</P>
