| Summary |
 09456: lw840: White screen |
||||
| Description |
This system is listed as working. When started a white screen appears - and that's it. Not sure if a floppy is required, and there's no software list. |
||||
| Steps To Reproduce |
>mame lw840 White screen, with a few black dots in the top corner. Checked with the debugger, it gets hung up at 017872 checking bit 7 of 0xffff37, which I guess is something internal to the CPU. |

The user manual claims that it should show the main menu once you turn the machine on. Also I find it questionable that a typewriter + printer combo is not marked MNW. |

0xffff37 is: rw(m_dma1, FUNC(h8h_dma_channel_device::dtcra_r), FUNC(h8h_dma_channel_device::dtcra_w)); It broke in 0.256, big H8 updates from OG in that MAME version. |
