Still working on the keyboard. It's connected to the 8031 serial port (Which is odd. I guess they really wanted it to be a terminal on a card.) rather than the mc2661 as on the PCD. Once that's done I'll commit it but the HDD still doesn't work either so it won't install yet.

Great work on the PC-X ... and good to see Axel "on board".

A few finds ... I had wrongly assumed that the PC-X used the OMTI 5300 MFM hard disk controller (which has a connector for a tape streamer as opposed to the OMTI 5100) ... Axel's PC-X uses a DTC520B. Now I suddenly wasn't sure if I had imagined mention of the 5300, but it's there ... in the Servicehandbuch Teil 1, page 217 relative to the PDF.

https://dl.dropboxusercontent.com/u/55419307/Siemens%20PC-D%20Servicehandbuecher.zip

I'm still baffled by the beep after the "Test End" message, which should be quite short.

Servicehandbuch Teil 1, page 194 says that the loudspeaker is driven directly by Timer 1 of the 80816 (if I read the source right, that's implemented), and that "to help switching on and off of the speaker, one bit of the Device Control Register is used ... Bit D5 = 0 switches the speaker off, Bit D5 = 1 switches it on"

There's also a sort of beeper on the keyboard that can produce key clicks and beeps (duh!) ... cf. page 174.

No worries because the OMTI and the DTC are compatible. I've almost got it formatting but it's trying to do some geometry detection as SINIX appears to support 9 disk types.

Nice ... the DOS HDINIT harddisk preparation utility has a list of drive types it recognizes (and I think expects as parameters at the beginning of its binary ...
Code:

Code:
306,   4,  17, 512
612,   4,  17, 512
640,   6,  17, 512
360,   4,  17, 512
640,   2,  17, 512
830,   5,  17, 512
1022,  8,  17, 512
830,   6,  17, 512

Here's the list from the sinix kernel. It also supports 1024 Bps at 9 sectors per track. Don't know about the 9th, the formatting program says there are 9.

Right,I've identified those drives from the HDINIT list ... second column is what the utility actually expects:

Second try ... system wouldn't let me edit the last post

The second column of drive parameters is now taken from the HDINIT executable ... notable differences are with the NEC drives.

B6188 BASF 6188 360-4-17 360-4-17

The sinix image in inverted in the video. Still am not sure how that works though. The video also shows the default user is "admin", I don't know what the password is though.

Great!

Found two relevant entries for inverse video in the Systemhandbuch Teil 1:

p.158 shows a simplified diagram of the video circuit ... a "inverse" signal is coming out of the 8041A

p.106 the TDS (test and diagnostics system) disks have a test for the function of inverse video
