Front Bay Adaptors
Several of our P-series of PCMCIA card drives for PCI bus are designed to give PC Card slots in a front bay. These fit into a 3 1/2 bay (floppy drive size). If you need to use one of these models (P423, P113 or P223) in a 5 1/2 inch bay you can buy an plastic adaptor to so that the fascia fits into the larger slot.
These are available from "all good computer stores" on the High Street as well as PC peripherals catalogues and cost around £5. (USD $7.5)
