As some have mentioned, the B&Os are limited to using their own cartridges. However, keep in mind that the tonearm was specifically designed for those cartridges. The tonearms are NOT flimsy, they are, however, exceptionally lightweight. This, combined with the incredibly low effective tip mass of the B&O carts makes for a very good tracking turntable.
Your best bet would be to find a good condition MMC2 or MMC1 cart for that table. Or, step up to a B&O tangential tracking turntable with an MMC2 or MMC1. I currently have a B&O 9000 with both MMC1 and MMC2 and I can tell you, without a doubt, that it is a very fine combo.
