I had the day off work recently so decided to spend some time stripping down the machine to see what I've actually bought (and so I can determine how much of a money pit its going to be to get everything fixed/renewed etc on it). Having now been able to fully inspect the machine I've made some interesting discoveries......
Here’s the board, which I have removed from the RF shield (which has got a bit bent over on the edges and a lump cut out of the top left inside edge?)
As you can see - it’s a 1D1 board (circa 1992). This board predates Escom/Amiga Texhnologies by quite a way.
Kickstart 3.1 factory ROMs with 1995 Amiga Technologies date stamp. These should not be in here (least of all because they are three years+ older than the board itself. If in its stock form, this board should have 3.0 Factory ROMs.
Bit of bodge wiring. I seem to remember either my 1st or 2nd original A1200 motherboard back in the 90s having this same thing. I believe this was a legitimate production line bodge fix.
And finally I flipped over the motherboard to check the underside for the Amiga Technologies PC floppy disk hack. And it isn’t there! This alone is amazing news and tells me something surprising about the internal floppy drive that came in this particular machine.....
This is the floppy drive that was in the 1200. This is one of the drives used by Amiga Technologies as a floppy drive - but not the one most commonly used (and it has an Amiga Technologies barcode label on). However, Commodore also used this same model as it could be easily modified to work properly on the Amiga (and Commodore would have them modified accordingly). It looks to me like this was either old Commodore stock that Amiga Tech reused, or an Amiga Tech drive that someone has properly modified to enable it to work on the 1D1 motherboard. Either way, the motherboard I have is not modified to take a PC floppy, and therefore this floppy drive can’t be operating as a regular PC drive, it must be Amiga modded. Yippee!
Oh, and one last thing - the caps. They look like new (no bulging, no cap juice residue anywhere, no fishy smells), which is making me believe this board may have been recapped a little while ago.
So what next for this machine? Well, I want to recase it. While the original case (a mix of an Amiga Technologies Rev E case top and a Commodore Rev B case bottom) is in pretty good condition and hasn't yellowed, it has malformed on one side (top half, above the PCMCIA slot) either from heat or from crap moulding in the first place, so the top and bottom halves of the case don't fit together properly there. Plus, I've kinda gone off beige/cream coloured computers. I have managed to find stock of the A1200.net Transparent case, and one arrived from Germany late last week.
I also have an internal Gotek kit and a new PSU from Retro Passion, though I am rethinking the internal gotek in light of the discovery that the floppy drive is good. I have an external Gotek, along with external floppy drives, ready to use either way.
I will also to fit an internal scandoubler/flicker fixer - I managed to source an Indivision AGA Mk3 (it is very good, but not the one I wanrted as this one also has to clip onto the keyboard controller, so if I ever recase into a Checkmate case, I will have to lose the scandoubler).
I already have an 8MB RAM expansion for it (the Wicher 1211 with Ethernet and SD Card daughterboard). I plan to upgrade from that to a Vampire V4 Ice Drake next year when they go on sale.
