Roland MKS-30 with 2 voice replaced to clones

"custom made juno chip"
Curious if these are SynthSpa's. Note there is no mention of the JX-3P. The MKS-30 is known to be a JX-3P in a rack with some modifications. The PG-200 programmer works on both.
Update via Alexey: "I developed my own project for the repair roland synths . in the future I plan to add different versions of the project : 12/24 db switch (like in roland jupiter8), aditional filter switch -add board with more classic filters polivox/moog ladder/korg ms/steiner-parker/arp4075.
and i do clone mc5534 fo juno106. i plan to modify original schematic of mc5534 to add additional tuning voice(2th dco). i maked juno 106 chorus mod- to reduce noise and add 3 channel essembly chorus, add speed, depth ,feedback pot.....
With best regards Alexey"
