Hello again folks -
Im trying to acquire the first revision of the t1600 or t2600 fmv in order to avoid (the marriage of system boards to the unit) the PCA/mainboard marriage issue noted by Tom.   Apologies if there appears as spamming.

@PJL COMMENT MODEL=HP DesignJet T1600 Printer
@PJL COMMENT MODEL=HP DesignJet T1600dr PostScript Printer
@PJL COMMENT MODEL=HP DesignJet T1600dr Printer
@PJL COMMENT MODEL=HP DesignJet T2600 MFP
@PJL COMMENT MODEL=HP DesignJet T2600 PostScript MFP
@PJL COMMENT MODEL=HP DesignJet T2600dr MFP

@PJL COMMENT MODEL=HP DesignJet T940 Printer
@PJL COMMENT VERSION=CYCLOPSNEPTUNE_08_22_11.1
@PJL COMMENT DATECODE=20220316
@PJL COMMENT UPGRADE SIZE=1407139808

CYCLOPSNEPTUNE = t940,t1600,t2600 series.  may be seeing if theres some one on line who has sold one and see if there usage page has the firmware version different to that.

and let me know the version as i will also be checking.

anything i find ill add it here.
