So, of course, I went and found a Unidisk 3.5" drive... This is correct. The LIRON card works with the Unidisk 3.5, Model A2M2053. # #The combination doesn't work, *even with every other card pulled*, so here #are my questions: Either the card, drive or cable is not functioning correctly. # #- Will the LIRON card work with the Unidisk 3.5" drive? My reading of #several FAQs says "yes", but maybe I misread something... Yes, and only yes. # #- Does anyone have docs for either the drive, or the card? There are no #switches or jumpers, and the installation seems obvious, but who knows, #maybe I missed something.... Plug and play. If the card is in the highest used slot, it will boot a properly formatted disk with ProDOS on it. # #- Can you boot from the 3.5" drive? Or is it only for storage, and you can #only boot with 5.25" drives? Yes, but it has to be in the highest used slot, or you can select the slot after booting from another device. I have had both bad LIRON cards and Unidisk 3.5 drives. If you don't have any other cards, drives, or machines (like a IIC+) to allow for an easy mix and match test, then locating the problem will be more complex. Louis
