You can build your own but I don't have the details, perhaps Drak does and is willing to share them. -andy > On Feb 20, 2022, at 10:46 AM, Jules Richardson via cctalk > <cctalk@classiccmp.org> wrote: > > > Hi all, > > A friend of mine has just acquired an Indigo (R4k with XZ graphics option), > but of course it's the usual story and the keyboard/rodent had been lost.
