Hardware projects - which would be most popular?

[david@uow.edu.au (David Wilson)]

I am thinking of designing and building a few hardware projects for
my Apple // systems. I am considering going to Kfest 2002 and were I
to get working prototypes by then I would bring them with me to show off.
Are any of the following of interest to anyone else but me?

1) PS/2 keyboard and mouse to ADB adapter (for //gs)
2) PS/2 keyboard to Apple //e adapter
3) PS/2 keyboard to Apple ][+ adapter
4) 5.25/3.5 FDD controller to Apple 50 pin bus
5) 5.25/3.5 FDD controller to Smartport bus (for //c and //gs)
6) Smartport to SCSI bus adapter
7) Smartport to IDE/ATAPI bus adapter
8) High speed serial card with onboard PPP processing

Numbers 4 & 5 would use standard PC disk drives but use GCR formats
giving the following data capacities:

DS/DD 40 track 5.25"	320KB + read/write Apple 5.25" disks
DS/DD 80 track 5.25"	640KB or 800KB + read only Apple 5.25" disks
DS/HD 80 track 5.25"	1200KB
DS/DD 80 track 3.5"	800KB (Apple 3.5 compatible)
DS/HD 80 track 3.5"	1600KB
