Wow I wanna say I am impressed with the effort to save this wonderful beast of a machine. My hat is off to all who are trying.

I have searched high and low to find a replacement for my beloved sp808 preferably portable.

Incomes the iPad but no success in finding apps that do what half the sp808 can do. So I set about building a sampler /looper using a Raspberry Pi but the hardware connecting with Python programming language has proven to be quite difficult for me any ways. So back to the iPad, I looked at Swift programming language, watched some tutorials.

So now I have decided to build an sp808 IOS app minus the 4 channel digital recorder and d-beam . So it will have the sampling and looping capabilities of the sp808 and to keep it simple for now no effects but I am sure we can add that later. Another idea was to incorporate the IOS app called Samplr into it where you can manipulate the wav file in realtime with the iPads touchscreen...how cool would that be.

I wrote the Samplr developer in hopes that he will either release the code as open source or work with me on this project ...stay tuned.

Hello,
I'm posting to see if anyone got the SP-808 drive up amd running. I've been trying to find a working ATAPI flash drive for ages. Any help would be greatly appreciated!
Thank you

Unless HaQue can enlighten us to the contrary, you might like to try the SalvationData adapter with my suggested ATA-to-ATAPI modification.

Ive got the adapter, but been too busy in all aspects of work/home to go further. I bought a mainboard of the unit to try and do additional testing but the shonky eBay seller gave me the wrong board (control board not a mainboard), and will not answer email or phone. I still plan to buy an 808 but just tied up.

Was anything else ever done with this? Were you able to test the Salvationdata drive?

3 years later and still nothing to report unfortunately

too many things on the go all the time, and let this project go stale. I still have the SD adapter. If Chris is still interested, I am willing to make the mod to the board and work something out to test it.

I understand. I have let many a project go stale. I only ask, as you guys have done the best testing and investigating that can be found online. I'm considering modifying my unit, but man, I hate to spend $80 on a unit, and the find out it doesn't work.

Sorry if this is a stupid question to ask, I came up on the thread when googling ide HDD replacement and quite like the idea of using a usb flash drive to replace the HDD on some older stuff. know most would say go for a cf adapter but those that USB to IDE converter from Salvationdata work as a normal ide device? Does it have an option for master or slave configuration on the board?

The problem is that the IDE host is expecting to find an ATAPI device, not ATA. SalvationData's adapter is designed to be configured for either mode via a programming resistor.

In my case my device as i know is looking for ata. Is SalvationData way to change from master to slave thru the 2 pin jumper it has on one side? Once again sorry if these seem like rather basic question to people more knowledgable in this.

You can connect up to two USB devices to SalvationData's adapter. This is explained in the technical manual for the S1R72U16 chip.

You will need a USB hub. The first detected USB device will be the master, the second will be the slave. Any additional USB devices will be ignored.

The chip has a pin which needs to be programmed for "two-device mode". I don't know whether the adapter has a jumper for this. If not, then you will need to hack it.

oh i see so the only way to get a slave is if it has 2nd usn which is the master, it cant just put a single usb into slave mode.

It an older console that when the GD-ROM goes bad on it people do an ide hdd to replace it but the software asfar as i know only recognizes ide devices that are in slave mode. To me a usb would be much better then hdd just because of how easy it would be to remove it and add more game to it.

ISTM that you can configure the adapter as a slave in single device mode. There are no jumpers for this. You just need an IDE cable that uses the Cable Select pin to determine whether the adapter will be master or slave.

Quote:
2.1.2 Device Count Setting

This specifies the number of storage devices connected to the main CPU via this LSI. Set to two-device mode when controlling two devices (master snd slave) using the LSI. Set to one-device mode when controlling a single device; in this case, the CSEL signal shall be used as defined in the IDE standard.

The CSEL pin on this LSI should be set to “Master (=Low)” in two-device mode.

I fail to find a single dreamcast using an actual flash drive the close thing to a flash drive if you google what you is the DC SD Adapter which look like a flash drive that get plugged into the back of it but it is isnt a good method to use compare to an actual ide mood.

I would think that it would be unsafe to treat any USB device attached to this IDE adapter as hot-swappable, if that is what you are expecting.
