    Does anyone know exactly what the added benefits are by upgrading to OS4?

    • @TheBizzyBScience
      @TheBizzyBScience  2 роки тому

      The OS v4.3 upgrade provides bug fixes related to midi communication and system code issues.
      Added - Timestretch
      Added - Read and write S3000 format disks
      Added - 2 track hard disk recording

    I am pretty sure that OS 4.3 crashes when you try to load/convert s900 format disks on the s1100. So it may be worth making a backup of the old OS to disk if that is something you will be doing btw.

    Interesting video. I did the same upgrade on my Ensoniq EPSm 2 years ago (2 OS EPROMs).
    And these EPROMs were quite hard to take off too but everything worked well.
    The next upgrade I'l have to do will be on my own S1100, not an upgrade actualy but more a fixing: The display light.

    It reminded me changing the amiga roms sweating in the summer... Are the samples distorted both from floppy and input? I had a look at some S1000 and S1100, the S1000 is still cheap while the S1100 is near the S950 now. Good video btw!

    You can reprogram them but you will need a eprom eraser and a programmer. I have done a few of my samplers by erasing the original eproms and reprograming them with a TL866II Plus Programmer.

      Its funny you said that ! As it happens I am messing around with a XGecu Pro as we speak, I had to turn off chip id and was able to read the info , but programming it back to another 32 Dip chip failed, Any tips would be appreciated!

      Peel the label off the eprom you extracted, if there is a clear window you need to get an eprom eraser that emits UV light before you can reprogram.

    Shame eprom didnt work bizzy, just remember that the psu is a 5v and 12v. Any question on wiring, just ask 👍 and try the digital out. It will eliminate the audio board from the equation. The board looks a bit dirty round those ic’s, wonder if anything has been spilt in it. Give it a good clean with 99% isopopyl alcohol and a toothbrush. You never know, if anything has been spilt, it may be slightly conductive. Worth a go. Fingers xd for you bro. 👍

      So do you mean that the sampler uses 12v and 5v?If the voltage is correct and the watt is enough,it will work well.
      But what i concern is that the new power supply is a switching power.I assume that the new psu may not match the audio equipment standard and the high frequencies could mess with the impedance values that was designed for the old psu.

      @cutnrun22 2 роки тому +1

      @@lanmichaelmix2818 The logic is 5v and 12v dc (i believe for the floppy and hard drive), the audio board runs off a separate transformer, +-12v, this mod is discussed elsewhere and has been done by a lot of s1100 owners. As long as 12v rail on the new psu is loaded with 50w 47uf chassis mount resistor to enable voltage regulation, it should be good. The original psu if fails, overshoots voltage and fries the motherboard, the replacement has output crowbar circuit to prevent this happening. I am open though to the thought of impedance values, im not that well versed in understanding it, and please if you have anything to add / warn us of, feel free to throw some knowledge out here 👍 im always willing to learn and listen to differing opinions.
      Thankyou LanMichael.

      @@cutnrun22 if the audio board is well isolated from the digital board,i think that it would be okay.If the new psu has good regulation of ripples(which is rarely be the case of switching power),i ain't a problem.Anyway,digital ICs don't require clean DC,but audio circuits do care about impedance,just a few nano henry inductor can affect the total signal quaility of an opamp,it's really complicated topic because impedance isn't the same as resistance,it's like the resistance for specific frequency only,you can't interchange component between those.That is why they use linear power like transformer so that it can easily regulate the ripples so that at least the amplifier can gives clean output.

    it's interesting that the two epproms were labeled lsb and msb,it could be *least significant bytes* and *most significant bytes* don't know why they call these just like that.Sad that it didn't work,i suspect it has something to do with analog sections.

    Just a thought bizzy..... Have you considered looking at the op amps located on the audio outputs? These can be a problem with age.

    • @TheBizzyBScience
      @TheBizzyBScience  2 роки тому

      The thing is , i have changed the whole of the output boards and it has made no difference, so I guess that's ruled out. but I will look into the op-amps , do you know if there on the main board?

      @@TheBizzyBScience I'm not sure where they are located on a s1100 but I know that they are located on the main board of s2000 & s3000xl at the back. I've had issues with them on my novation nova. Common makes of op amps were often by texas instruments in samplers and synths. I could be wrong though Bizzy, it's a nightmare when you can't trace a fault.... Like looking for a needle in a haystack. Keep on going mate I'm sure you will nail it in the end👍🏻👍🏻
