Well after skimming through the video, I was screaming at the camera at you... LOL... 

Take the cards out! take the thing apart! its no good to anyone if we cant really see what it is, what it can do, or what it did.... 

Watching how you were trying to remove the cards was painful. LOL. its like friggen pull the card out already. sheesh. 

Anyways, Rant aside. I think the large board on the side is a memory expansion. To access the HDD, it would had to have a modified ROM so it can boot from it, or a special floppy to load the HDD drivers. 

I can only "assume" one of the card is an MFM controller.

good man techknight - i want to tear it apart like yesterday - but there are wires soldered all over the place and i have to take pictures of everything. I dont like putting too much force on boards - would it be ok to lever the cards up instead if just pulling them straight up - this thing is old....might end up ripping the entire slot of the board. Is there any point in spraying wd40 into the slots. That colored ribbon cable i held up to the camera has a pretty good length to it - me thinks it was plugged into some external  machine, looks like this may of been used in industry . I think the 4th slot is a video card - it has thoes white wires coming out from the back of the card - i think they are the same wires soldered onto the analog board  analog board does not look like any apple board

im getting older and more paitent man. I intent to strip this baby bare and ill take pictures of everything and share the here,

 
my god.. these cards were stuck in there pretty bad - levered them out - 

Video card had 2 wires attached and 2 that seem to have broken off.... BEFORE I TOOK IT OUT!!!!....

Motherboard says apple on it - i only have apple ii e's - dont know if its a clone or not

looks like language card/ memory expansion card

serial card

z-card - is that the same as z-engine c/pm card?

video card

floppy controler

ide or scsi controler card - dont know which?

will start taking it apart tomorow

That Z card has an SGS Z-80 CPU,so it might be a CP/M card. I replaced a ton of those SGS cpu's from Italy way back in the 80's. They were used in bar code readers and had a high failure rate.

Put stickers over the window of those EPROMs. I figured it had to be an Apple II recase hack. What the heck kind of setup was that ISKRA?

Oh man, this is the coolest thread I've seen in a while! That machine is crazy, and I'm delighted that it ended up with someone on this board - I'm dying to see where this goes...

If you can ever take out the logic board and fix it up, there's an original Apple II board for you. Now, when was it made? ;)

I think it's more likely it's a II Plus board, and not a particularly early one. (It's totally missing the 4k/16k jumper blocks, for instance.) Without getting my Plus down and taking a look I'm sort of inclined to say it's one of the post-1982 ones that says "Singapore" on the back, because that's what's in mine and it looks suspiciously like the same thing.

Do you mean the big board to the left (looking from the rear) of the drive cage? No way that's a memory board. Notice how it has three ribbon cables coming off it, one of which goes to a slotted card in the motherboard (see below). That's pretty obviously an MFM-to... something, disk controller. I want to say that "something" is SASI, 1978's paleolithic predecessor to SCSI, but it could be something proprietary. (I don't think it's Corvus, it looks like that used fewer pins.)

The board with a blue connector looks like a Printer card.
Given that it appears that this connected to the board above I'd say it's the host interface for the hard drive adapter board above.

 
... been skipping through the video, per an observation at around the 11 minute mark, a IIplus motherboard doesn't have a joystick port. But you've probably figured that out by now. ;)
