EduQuest Model 30 (another "turbocharged" Model 25) 9603-01X
Special thanks to Tim O'Connor
over in Decatur, Illinois for this unit.

At present I do not have much information about operation or maintenance of the system. IBM doesn't appear to have any information concerning it nor does the Web in general. While your EduQuest system may vary a little from these specs, this is how my system is set up right now.
As mentioned above I do not yet have much information on this system but every day now since Tim dropped this off I have been getting more bits and pieces. If you have ANYTHING on the EduQuest, don't be shy--drop me a line! Even if the EduQuest you have isn't listed yet, I am always searching for them and even if I don't get one of the unit you have info on, I will post your info and give due credit.
IBM 386SLC-25 CPU (soldered)
4MB Installed RAM
1.44 Floppy Disk Drive
DOS 5.0 is in ROM on this, just like with the EduQuest 40. A Setup utility is built in, there is no reference or starter disk I know of.
I have found that use of a disk manager (those based on Ontrack software) requires a "cooked" diskette as the EduQuest Models 30 and 40 (and possibly all other EduQuest) cannot boot the DR-DOS used with Ontrack's solution. I will be providing a "cooked" disk image here soon.
528MB disks are the maximum supported by the onboard IDE. Higher capacity is possible if you use a disk manager program.

You may notice that I don't have a whole lot of information on this system. IBM doesn't seem to have any info that I can find, and I've searched the web only to discover that I am one of the few people providing any information on these systems. If you have information on either the EduQuest 30 or any EduQuest, please do send it to me for inclusion on this site.
Components:
X1 - 12.000MHz XTAL
OSC1 - 14.318MHz (Software RTC, "Color Burst" signal (?), possibly ISA bus clock?
OSC2 - 50.000MHz (Halved to 25MHz--system CPU clock)
OSC3 - 16.000MHz (for ?)
OSC4 - 24.000MHz (for FDC?)
D4 - Green LED
Not quite finished here yet, but I'm getting closer...first I have to clean up and sort out all these pages.
