$8 - Ensoniq EPS Operating System Disk v 2.49 OS Boot. One brand new copy of the original EPS OS boot image on a labeled diskette. Version 2.49 (last one released). Image transferred to a high quality new DS DD 3.5" disk. Disk color may vary. Works for the EPS rack version also.

The EPS Classic uses double sided, double density 3.5" diskettes, which hold 720k, as opposed to HD diskettes, which hold 1.44 MBs of data (ASR10).

OS version 2.49 requires EPS firmware 2.40.(Eprom chip version). If you need an earlier OS version, let me know. Most units can run V2.49.

 

To find your firmware version:

Press Command, then Env 1 (Display then says:) "NO COMMANDS ON PAGE", but ignore this. Scroll right until you get to "SOFTWARE INFORMATION", and then press Enter. Displays current "RAM VERSION" (O.S. version you are using). Press Enter again to display "ROM VERSION" (this is your firmware version). If you don't have an OS disk, the only way to determine your firmware/ROM version is to open up the top lid (4 hex screws) and inspect the two EPROM chips labeled "UPPER" and "LOWER" on the main board. It may take some force on the left lower side. The version may be printed on the chip labels. If not, then guessing is all that's left. Take a picture and send it to me, and I will try to decipher the code. At least 90% of EPS's that I have seen can use OS V2.49 (ROM V2.40). I recommend trying V2.49 first if you are not sure of the ROM version. The wrong version will not harm the machine, it will just shoot an error such as "INCOMPATIBLE OVERLAY".

If you are getting the error "DISK NOT FORMATTED", or "DISK DATA CORRUPTED" you may have a faulty or dirty disk drive. If you found a thin 1/2" square of metal roaming around inside of your EPS, it fell off the top of your disk drive. It is a counter weight, and should be glued back on (center, top of drive - look for the glue mark). I've seen a few drives that did not work properly without this metal square in place. Plus, electronics do not like little metal things randomly landing on components!

It's also a good idea to blow out the disk drive slot with compressed air if you are getting errors, as dust and hair can collect in there over the years. Replacement drives are out there for about 50 bucks, but may be hard to find. They are NOT the same disk drives that went in your old Windows 98 PC, though they look similar, so don't be tempted. They came with NEC disk drives. A good place to start is TheSoniq: http://www.thesoniq.com/     408-829-0713   They are a great source for parts and ROM IC upgrades.

The original classic EPS requires a boot disk to start up the machine. It also asks for it during certain operations while running.

I used an EPS as my main sampler/sequencer for 13 years and recorded many songs with it. Click here to hear some of them. It's a unique and intuitive music workstation. Save your work often!

If you have any questions about the EPS,  I will gladly answer them.
