What systems does the DOS on Mac Card for LC currently support?
Macintosh 5200, 5260, 5300, 6200 and 6300 series computers.
Can I copy and paste between the Macintosh and the PC?
Yes, whatever is in one clipboard is translated to the other clipboard when you hot-key between platforms.
How fast is the DOS on Mac Card compared to my Macintosh?
These are 2 different platforms so a direct comparison is difficult. Macintosh is based on the PowerPC 60X processor while the DOS on Mac Card is based on 5x86 processors.
How fast is the DOS on Mac Card compared to the same processor and video subsystem configuration on a stand-alone PC?
Approximately 10% slower due to the shared SCSI hard drive.
Can I share the memory on my Macintosh system with the DOS on Mac Card for LC?
No, the card requires dedicated memory. However, the card uses the same type of SIMMs installed on the Power Macintosh computers, so excess memory, if any, can be transferred.
Can I be connected to my Mac and PC network at the same time?
Yes, with the dual TCP/IP extensions available through the optional DOS on Mac Network Pac users can have two simultaneous IP connections, one on the Mac side and one on the PC side.
Can I see both my Macintosh screen and my PC screen on one monitor at the same time (Window in a Window)?
No, you have two choices:
1. You can hot-key between the Mac session and the PC session.
2. You can attach a second monitor which will mirror the first monitor. This could be a large screen monitor, for example, used as a teaching aid.
Can I use a hardware key that goes on my PC parallel port with the DOS on Mac Card for LC?
An optional card with a built-in parallel/serial adapter is available to support all parallel port devices including hardware keys.
How do I partition my hard drive between the DOS/Windows and Macintosh environment?
We do not partition the hard drive. During the install you are asked how much of your remaining Mac hard drive you would like to allocate to a folder for the PC side. The install program then does it all for you.
How do you compare with Insignia Solutions SoftWindows?
On the platforms that we currently support, we are over ten times faster. This means that an operation that takes 15 seconds with the DOS on Mac Card takes over 3 minutes with SoftWindows. Plus, we offer true dual-processing -- two processors running independently as compared to software emulation running two operating systems on only one processor.
How do you compare with Orange Micro cards?
In general, our cards offer superior price/performance. At the present time, Orange Micro does not offer a solution for LC systems.
