Over in the Kontron thread, Robbbert mentioned
The Kaypro 10 issue is that we had no info on the hard drive and its controller. That is why it's marked as not working.
Well, in my Kaypro 10 the harddisk is a Shugart 712 series, 10MB MFM driveftp://bitsavers.informatik.uni-stut...-712_Hard_Disk_Reference_Manual_1984.pdf
According to the manual it's 320 cylinders, 4 heads and 32 or 33 sectors per track with 256 bytes per sector.
I wonder if the controller actually formats it that way ... it's a WD 1002-HD0 which offers different sector sizes ...ftp://bitsavers.informatik.uni-stut...-0030_WD1002-05_HDO_OEM_Manual_Jul83.pdf
One of the hard disk controller's chips, the WD1010BL-00, clearly has a masked off window. Is this some common MCU that has been relabeled so I could dump it?
Between the controller and the mainboard sits the "intermediate board" that is described in some internet posts. It only has two ICs (a 74LS00N and a 74LS138B1) and adapts the 50pin connector coming from the mainboard to the 40pins needed by the WD 1002-HD0.
MAME's kaypro.cpp mentions
- See about getting keyboard to work as a serial device.
- Need dump of 87C51 cpu in the keyboard.
My Kaypro 10 has an 8049 keyboard controller which I'll dump as soon as I have my equipment back.
