Another A590 questions (and maybe some answers)

[Chain]

Got a second A590 unit from my friend (almost for free, wohoo) so ive decided to investigate some posibilities and make a little resume.

First unit:
-no markings as rev. xx (?), but looks very very old
-LEDs are on wires connected to pins above XT/SCSI jumper
-U30 is fitted (marked as U101!) - its needed only for DMAC1 (see 590 serv. man.)
-has no PSU (im using CD32 one)
-512MB Quantum drive works, but i can format it only under KS2.x (?), it hangs on 0x1 error /w ks 1.3
original ROMS 6.1 (i have prepared another 6.6 set for this baby )


Second unit:
-looks very clean as new
-rev 7 board (i will make a photo for BBoAH)
-LEDs are directly soldered to pcb (uses also another metal plate)
-DMAC2 fitted, U30 socket is empty.
-ROMS 6.6, power connector is male standard molex soldered to board (as pictured in serv.man)
-I cant get it to work with the same Quantum drive as above, but works great with original XT drive (?)
-This unit have original A590 PSU, bur unfortunately without cable.


q1: I have only "A590 (Epson) setup 1.1" disk as dms. Is there any other version available???


q2: Can somebody open A590 PSU and measure output cable for me?? Pretty please. It will be best with a small photo
I need to know where is connected power_sense IN that PSU. (It seems to be connected to pin 6 on A500 expansion conn., just for info)


I will post some pics later (no dig. camera at home in these days )
