# SBC3 Emulator
2
3
It's quite a time consuming programming cycle for both the monitor and NetBSD, for different raesons in each case:
4
- for the monitor, you build then have to burn an eprom which takes several minutes
5
- for NetBSD, you have to load a 4MB s-record file over serial - again, that's several minutes

It would therefore be very beneficial to have an emulator for the board that was good enough for most testing. Obviously, the final proof of the pie still has to be running on the board but with a good enough emulator, development time could be speeded up hugely.

Mame already has all the components we need to emulate an SBC-3, it's simply a matter of creating a machine definition.
