| Mac 286 in a 7100? |
Posted by: rickrob on 2018-04-16 13:15:05
Is it even possible that a Orange Micro Mac 286 could work in a 7100?
I'm thinking No, as the drivers probably won't work under 7.1.2 and up.

Article talks about the need to turn off 32 bit addressing so I would think the mac286 is probably a OS 6 or MAYBE OS 7.0 card (they dropped support pretty fast).

Hi rickrob,
I've the same card (original Mac286 AST card, two cards linked up), and wondering what I could do with it as well! Confirming it needs 24 bit addressing and < OS 7.1, so not a good choice for a nubus PPC but might be of merit in a lowly '030 (or Mac II). Of course if you put it in anything faster, you could probably emulate x86 faster with more RAM and colour support. It's a fairly limited card, but cool for oddity's sake.

From what I read if you have a 5.25" floppy drive connected to the controller board of the card you can read CP/M disks with it (its not the normal PC floppy controller chip).
PC cards are fun to play with. I have a bunch of Orange Micro 386 and 486 Nubus boards plus Apples 486 6100 model and the Pentium PCI one.
I would recommend a Mac II or IIx for the 286 card (there are 2 versions a single card and dual card).

I figured it would not work in a 7100-- I tried it in my IIci, but forgot to turn off 32 bit addressing. The software seemed to boot up, but I didn't see a DOS window or any way to get to DOS. Can't find any docs on the web, there's basically nothing out there on this card. Mine is the dual card version.

Not sure about the 286 board, but the 386 models need some software to setup virtual drives and then you need DOS disks to install the OS and then load whatever apps you need. The DOS screen should be in a window on the mac screen (later cards allowed external monitors and sound, parallel, serial ports etc).

I think the 286 versions had DOS in ROM. Not 100 percent sure though.
I have System 7 Pro and a Turbo 040 card in my IIci. Guess I'll have to pull the 040 and try 6.0.7
I have a SCSI2SD in there, so I can toss in another SD Card.

The virtual C drive has DOS 3.3 installed but that is software not a ROM feature I would think.
