| 16-Bit BBC IDE Interface
|
The 16-bit IDE interface allows full 16-bit access to drives. The PCB has
1MHz bus terminators and a through connector. All BBC filing systems use
8-bit sectors, so only half of the actual drive space is usable without
using specialised software. If you want to experiment with accessing
DOS-formatted drives or CD-ROMs you will need a 16-bit interface.
Robert Sprowson designed
the 16-bit interface and PCB.
There are a couple of errors on the PCB, so the assembly instructions
include instructions to modify the PCB. The PCB is
too compact for my soldering skills to sucessfully assemble them (I've
ruined three so far!), so I only supply the bare PCB. Thanks to Robert
Sprowson, the surface-mount diode comes ready fitted.
