first thing is that the back of the case does not have the usual FCC etc compliance notes label, rather there is a label which is blank except for ruled-up boxes. The SCSI port has been merely added to the back of the battery compartment - the battery is there underneath and the case has not been cut or altered. The inside of the back shows a dark grey or black finish, no signatures (yes I know what they should look like)
There has been a fan added to the inside near the top - on a bracket stuck with double sided tape. The fan is wired to the analogue board.
Now the interesting bits..
the mainboard has several mods-
a board 3"x4" which plugs into the ROM hi and ROM Lo slots, and carries the SCSI out socket The original ROMs have been placed in this board , there are 2 custom chips and another larger chip. I take it that basically this board taps into a bus which goes to the ROM chips and and provides the SCSI interface.
The brand of this board is supermac technology 1986 though the chips are C 1987.
the second mod is a Scarlan Megaram, a board which sits on top of the entire RAM section in front of the 68000. It is connected to the mainboard by 4 risers which have been put where RAM sockets were. It must at least double the memory capacit as it contains 21 RAM chips, and 2 control chips that look like they might have been taken from the mainboard.
There is a little veroboard circuit sitting on a little riser near the 68000. It contains a chip. It kind of looks like the local guys bought these upgrade parts and installed them in 1987, but still had to fiddle to get it working. A lot of effort, but maybe the expense of the computer justified it
the main board is copyright 1983.

No I wont do anything to it - I guess it already has some card or
suchlike added to it. I'm curious as to whether it has a HD or fan
installed inside because of the sound. I'll need to grab one of my
other old macs ?my classic 2 to make a startup disk for it. Can it run
6.0.2?
I think this last question outweighs everything overzealous listers might
have felt ;-) . If there is damage, it is done already, and it was done
before Andrew laid careful hands on this orphan. Remember the subject line.
As for the Classic II running System 6, I would not bet my last shirt upon
it as the C II originally came with 7.0.1; but you can always try as there
are other 68030 Macs capable of running OS 6, IIRC the SE/30 and the IIcx
shipped with 6.0.3, the IIx with 6.0.1.
Keep us posted about this baby! This is a very interesting thread.
