MOTU Issue: Problems installing the Express PC
Usually problems with installing the Express PC means there’s a resource conflict happening in windows. The Express PC works best on IRQ 5 and 11 (2 and 9 share the same resource chip, so they’re not really different IRQs, and 2 is always taken). Go to the device manager (right click on “My computer” and choose properties). Double click on the computer icon at the top of the list. If a device is taking IRQ 5 or 11, you will need to move the device to claim another resource, so the Express PC can operate properly.
As well, you can view i/o addresses in device manager (same window as the IRQ list, just choose the i/o address radio button). No other device should be taking an i/o address range of 300, 304, 340 or 344.
If the problem is persistent, check the ISA card type. If you’re running an 8 bit card (one connector to the ISA slot), it may not work with faster computers like Pentium II/III 200/500MHz machines. An upgrade to a 16 bit card may get you up and running. If you’re registered, you can get a replacement 16 bit ISA card. Contact Tech support at 617-576-3066 for details on ordering a replacement ISA card.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
