I know it’s a bit insane, but I got a very good deal and bought an MKS-70. The MKS-70 is the rack version of JX-10. The JX-10 contains two JX-8P. So at the moment, I have a total of five JX-8P engines!
It seems to be fully working, has a few scratches on top and the front panel looks very nice. However, when booting it and pressing the VALUE button the screen read “Ver 1.03 FINAL JX”, which is not the last version of the firmware. Regarding “FINAL JX”, it’s kind of strange because it was not the last JX synth produced (JX-1 was the last one, though it’s not analog) and it was not the last firmware version either. Just like on the JX-10, the firmware was very buggy on the MKS-70, but they got it all sorted out with version 1.08. I’ll have to open the MKS-70 and check what kind of EPROM it uses.
