Rare Macintosh Plus with Total Systems Accelerator Board

[Crutch]

Yes the SCSI2SD 5.5 should definitely work on your SE's SCSI port (since that will have term power, unlike the stock Plus SCSI)!  I use mine with a right-angle adapter so it bends up nicely against the back of the Mac instead of sticking out 3 inches.  It's lovely.

This looks fairly different on the inside from my Plus with a Total Systems accelerator. I do use mine with an external SCSI2SD and really like it. It's my go-to compact Mac because it's easily the fastest one that I have.

That's the thread I was thinking of earlier!

Curioser and curioser.

So what is the blue graphics card connected to on the accelerator board underneath? And what’s that little green card standing up behind the graphics card?

Not sure if it helps, but that display card is definitely made by Lapis. The blue is a telltale sign, but the FCC ID confirms.

Anyone ever seen a driver for this sort of card? Is it the "Dual Screen Software SE 2.E" one? Or something else? Lapis seem to have different drivers for every day of the week and way the wind is blowing. Is wish they'd rolled the functionality into a single driver instead of one for every card.

The card name from TattleTech might be enlightening.

Sadly there probably isn't any info in tattletech. Its in a Plus, so it is piggybacked on the CPU, not in an expansion slot.

Even on the SE cards don't use, what is it? Slot Manager? Anyhow, its not like the later machines.

I could swear Tattle managed to read some info off my SE cards....but yeah good point on the Plus. In that case it'd probably take a ROM dump to find out what the heck it is. From the Lapis ROMs I have I've noticed they're good (or bad, depending on your perspective) on giving every single card it's own string somewhere in there.

I can't remember how much you get on the SE, I feel like it is hit and miss depending on the card... but I can’t remember at all really. I certainly have cards I've tried to find out about and they were just invisible without a driver.
