Orange Micro NuBus PC Card - Need Help

I just found and bought an Orange Micro OrangePC NuBus 66mhz card, the seller says it looks like the 220 version but since it only has PCMICA card slots and no external connectors, I would assume it is actually just a 200.

Anyway, long story short, I am trying to figure out what software/drivers I need, and where to obtain them.

Member Charlieman stated in an earlier post:

*** OrangePC NuBus 200 Series

With the NuBus 200 Series, Orange adopted a "pick and mix" approach to features and processor speed. Depending on your budget, you could buy a 486 card with VGA or SVGA graphics, real serial and parallel ports and a PCMCIA expansion connector. The VGA/SVGA chip is provided by Video 7. The PCMCIA connector, which replaced the ISA slot on previous NuBus cards, was intended for a sound or network card, but other devices may work. Orange Micro advised users to use monolithic network drivers, rather than installing Card Bus or PCMCIA management drivers. Almost everyone who managed networked PCs in the early 1990s will agree with this recommendation. The cards have a single 72 pin SIMM slot and the processor can be upgraded. Orange Micro specified 32MB as the largest SIMM but it would be worth trying a 64MB or 128MB SIMM if you have one lying around.

The 210 is the entry level model with limited graphics capability (VGA) but a real serial and parallel port. The 250 has better graphics (SVGA) and a PCMCIA connector, but no serial or parallel ports. The 290 is the top of the range model with all of the functionality provided by cheaper models. A 220 model later appeared with similar functionality to the 210 but with SVGA graphics. Orange Micro's cards were more expensive than an Apple Houdini card of the same period, but had more PC compatibility (eg the ability to support software protection dongles).

The 200 series cannot use a separate monitor and video is displayed in a window on the Macintosh desktop or, for best performance, in full screen mode. A multiscan monitor that supports 640x480 and 800x600 resolution is required.

For your interest, this is the card I just purchased

PS. I see it sold for best offer, how much?
Thanks for the help, I totally forgot about the internet archive. I thought the higher end models had connectors not just PCMICA like this one appears.  I won it for $100 which is pretty fair considering the rarity.  I have like $650 into my Quadra 950 and this will be the finishing touch.

The higher end models of the 300/400 series do have an octopus cable with audio, serial, video, gameport , printer ports etc. That card is cool because it is the only one with pcmcia they made.

Interesting, I think there is a lot of incorrect info about the 200 series online.  I am thinking of finding a Sound Blaster PCMICA card, but I am not sure which might work for this unit.

This one is PCMICA but shows it requires Windows XP...  I think I would be using Windows 95 so I am not sure if it would work.

I'd love one of these cards, been looking for years, 386 or 486.  Closest I've gotten is owning a Mac286 card, but it's limited to a low 286, CGA, 1MB RAM.

The Audigy2 PCMCIA sound card is 32-bit cardbus and not compatible with 16-bit slots.  16-bit PCMCIA sound cards are hard to come by, there are devices such as an OPL2LPT external parallel sound card that might do.

Cardbus have those round balls on the end and won't fit let alone work in a 16 bit PCMCIA slot. You are stuck with the usual modem/ethernet/scsi/wifi/special CDROM controllers for that slot.

I like collecting those Nubus OrangePC cards. Think I have (2) 386 models and (2) 486 ones.

I got it today and looks like fun, I was able to remove the memory which some have said it’s easy to break.  Does anyone know the max size?

Yes, I should have noticed the difference of the cards.  I did find a nice list of audio cards that anyone viewing this forum should use for future reference.

Necro'ing this thread for a related question. I've got the same card (OrangePC 290) and I'm seeing visual artifacts appear soon after opening any program with graphics (e.g. Windows 3.1, Simcity). My guess is this is a VRAM issue, but I haven't stress tested this card to know if this happens after a while in DOS as well. Any ideas? Would I have to resolder new VRAM chips on? 

Note on the 'A20 Hardware Error', I think that's from swapping in a 486 overdrive instead of 486dx2-66 rather than the video issue, but that's just a guess.

A20 is a keyboard error. I don't think that card has its own video chip or VRAM since there is no video out cable. The video is using the macs built in hardware for display. Does the card work 100% with the original CPU?

Same issue with the original 486dx2-66 (the solitaire image was from that). Interesting I didn't realize it used internal video but that makes sense.. I figured the two large chips to the bottom right of the 486 were VRAM but I guess they're the 128k cache the card comes with.

Sounds like I should swap back in the dx2 and see if the A20 error comes up again. I can also swap the RAM, haven't tried that. Any other ideas?

My only idea was the CPU (or a support chip overheating or shorting to something) causing timing issues with the software.

Ok, looked up that WD90c30 chip and it is a VGA chip. I had looked that CirisLogic chip up and it is not for video so I called it a day.

The Cirrus Logic chip is the PCMCIA controller. Note that it is impossible to make a 100% Sound Blaster compatible PC Card since the standard lacks any sort of DMA pins.

Ok so VGA and VRAM is on-board. Am I right in assuming the visual artifacts are likely VRAM related then? I've read about something like this happening before from other vintage hardware, but want to isolate the problem best I can before I go looking for new chips & someone to fix it. Thanks!

Curious card. Has anyone got a version with the IC implemented on the pads far left or botttom right? PCMCIA alone seems quite a limited choice for I/O on the backplane.
