While he is cloning the Gotek HW, he is running HxC firmware.
I do not know if there is an agreement (licence ?) between piotr and Jeff. If this is not the case, then this should be known.

For a drive to answer A and B while internally connected means that the SEL line at uC interface is always low (bad jumper configuration) or the uC is ignoring it.
Only Jeff can answer the software side and we all know piotr answer from HW side  :doh: .
@Jeff_HxC2001 any chance of an official HxC device in a 3inch drive chassis?


If it is not the case that Licences have been paid then I have been ripped off and I want my money back! The MxC firmware is worth every cent and Jeff should be rewarded for his hard work

Fo me is  the same circuit that the 6128 usb ,but it have removed jumpers, and add the screen part. Rearanged conexions as the necesity

Take a look:

http://www.eightbitclone.com/6128.html






The firmware is the same for the two i think.so the chip connections are the same.

Search were are connected the lines go to the jumpers drive configuration from your chip.

I think he designed it to work as a and b.

Maybe you can put a good picture of the pcb?

Yeah, I'll see. But the lcd is soldered on, so I cannot scan it. I'll try to get a good picture on the phone later on.

The sloppy work on pin 2 is not a good sign.
It looks like the connector pinout is wrong, and this is confirmed if the jumper select between A and B.
Drive select signal are on pin 4 and 6, the jumper block is on pin 6 and 8 (Motor On).

That is how it came. I have not stripped the plus one from it's 3d printed chassis to see if it is soldered as 'interestingly' yes I think I can solder pin headers better than that.

OK..... Here is the other board. Still really rough soldering. But is anyone willing to help me out here. These will be the last thing I buy from @Piotr and I can only recommend others to stay clear.





Since the drives are not as advertised, and not fit for purpose I wonder if I can get a refund through PayPal.

Paypal normaly gives the reason to the buyer.

Anyway. Technically speaking. If your live inside the u.e and the seller lives in the u.e . The product is cover by the u.e laws. If you are in the same country as the seller.  And you want complaint you can go to local consummers office.

If you live in other country as the seller but inside u.e you can go to the european office consumer and make a complaint. Its free. And they contact to the seller to search a solution.

I wonder what the solder blob is doing, connecting pin 4 & 6 (also seems there is a trace going to the jumper block).
Pin 4 Drive select 1 (That would be drive B or ?)
Pin 6 N/C ?

Also it's hard to see if Pin 4 and Pin 2 also interconnects (probably not).. And probably the jumper was routed to pin 6, but should have been pin 4, you tried messing with the jumper there (disconnecting it)?

on a 3inch drive
- 2 is the index pulse
- 4 is drive select 0
- 6 is drive select 1
- 8 is motor on

On that drive it look like pin 4/6/8 where shifted. To fix this
- he cut the index track going to pin 4 and connected it to pin 2
- removed pin 4 from the connector (I don't get why. once disconnected from index, there sould not be any problem)
- connected pin 4 and 6 together. I also do see why : pin 4 is disconnected and connector has no more pin.

What's missing ? He should have disconnected pin 8 from the track that goes to the jumper (drive selection) and connect it to pin 6.

@CraigsBar : the drive are answering to both A and B drive because the drive select jumper uses the motor on signal instead of a proper drive select (and it look like the Gotek does not care about the motor on signal at all).
 To fix it, you need to :
- replace the missing pin on the connector (and remove the bridge beween pin 4 anb 6), to restore connectivity for DS0
- Optionally disconnected pin 8 from the track that goes to the jumper (drive selection) and connect it to pin 4
- place the jumper on outer side of the jumper block to select DS0

@gerald:
Seems you nailed, btw. where do I find the correct pinout of internal 26 pin connector, I was looking at this:

Edit: found it in the DDI service manual.

Many thanks Jerald, so let me clarify this...


1. Remove the SOlder link between 4 & 6
2. Cut trace between Jumper pin and pin 8
3. Connect the same Jumper pin to the newly restored pin 4
4. Leave the jumper where it is and it will be DS0 and work with my ABBA switch.


Seems simple enough. please confirm that the below crude drawing is correct. Blue is the current config. Red is the changes and the solder bridge to be reomced when te new pin is inserted

I have tried to contact @Piotr through SellMyRetro, PayPal and here... with no response. If he does not get back to me I'll raise a calim with Paypal for a refund. Depending on the putcome of that I'll try the mod on one drive.


Ideally I want both working as drive A if the mod works (And I see no reason why it won't then I can handle that.

Guys, I bought my HXC from Piotr and I'm very happy about delay,shipping and material.
My HXC was originally designed for ZX Spectrum, I just adapted the case to fit into my CPC+.

Piotr  doesn't answer at the moment, as he is on holiday out of country.
I'm waiting him back to order from his shop, a buzzer for my HXC.

Be nice with him, he is not doing HXC for business but only to move forward on AMSTRAD/SPECTRUM stuffs to help us.  8)

This isn't a once off, experience. You may have had an ok experience with him, but there are soooo many users (including myself) that have seen a completely different level of support. He can't be on holidays for 6 months of the year. I posted several questions to him, which he completely ignored although he was logging into the Forum during that time. And I'm not alone. Either Piotr gets his act together or he can go elsewhere. We have enough other users that build top quality hardware for the CPC scene. Gerald, ToTO, Duke, Jeff, etc. We don't need his half finished, non-supported rubbish. His hardware attempts aren't moving anything forward, he's just peddling badly designed crap to make money. If you need examples I can supply you with several. He had his chance and blew it.
