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 drive

ftp://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 ...

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.

- 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.

Are there any parts (ROMs, etc) or pictures needed from other Kaypro 10s? I have one that is moments away from the trash but I'm willing to save/document anything wanted.

I'd take it off your hands ... at least the boards and keyboard. Where are you based?

I'm in VA, USA
it's pretty beat up and I just noticed now that the connector on the keyboard (the RJ11-looking one) is broken and loose inside the case.

I can take some pictures of the innards later if you want, any recommendations for an easy place to upload images to link here? I haven't needed to use one in a while, and I logged into photobucket for the first time in years and it's a hot mess of ads and random hijacking

Hi Sharkpuncher,

I'm using imgur for the pictures.
If possible, do any and all dumpable ICs even if Kaypros are pretty documented - the BIOS ROM, the character ROM, open the keyboard and dump the 8049's ROM.
And then comes the dreaded WD1010BL-00 - at least on my harddisk controller. It's clearly a part with a ROM, but we'd need a clue as to what IC part it is so we can set the programmer accordingly.

If you can ship it for a non-lethal amount of money, I'd gladly rescue it.

If Sharkpuncher wants to send me the WD1010BL-00, I'd be happy to decap it and take pics so you know what it is.

Ok. If I get a chance this evening or tomorrow, I will pull it apart for some pictures and if you want to pay shipping I'm fine with sending it wherever. If I remove all the parts that make it a boat anchor it should not too prohibitive to ship...does the HD or floppy drive have anything that needs to be saved for decapping?

OK, thanks, Sharkpuncher. If possible, send the drives too ... nothing to be dumped, but maybe to be imaged. I can do that on my end.

@seanriddle ... thanks for the offer! I'd say we wait for Sharkpunchers pictures to see if it's even the same controller as I have.

Sorry for the delay, I had a busy weekend. Here are the images I took, I can see a few differences between yours and mine.

Main board

IO Board

"Intermediate" Board

Floppy Drive (Top)

(I guess it was commonplace to have to adjust the timing on drives?)

HD Controller (Seagate ST-212)

I didn't take apart the keyboard but I can do that if you wish. Regarding the drives, for the HD there are a couple wires that are hardwired in at another location (one looks like a ground line and the other is for the LEDs), so if you want the drive as well let me know if you want me to cut the wires at a certain point or if you have any particular advice.

Oh also I do have the capability to dump chips, though I have yet to do so. So I can also try giving that a shot if you want.
