How to order
To place an order email me to let me know which converter you want and your email address. I'll send you Paypal invoice soon.

My email is: hasu@tmk-kbd.com


Price
USB-USB:  $57USD
M0110: $47USD
IBM4704,Sony NEWS: $44USD
ADB, PS/2, NeXT, SUN, X68K, PC98, IBM Terminal: $34USD

Payment: Paypal Invoice will be sent to your email. You'll be able to make a payment with credit card on Palpal even if you don't have Paypal account.


Shipping to CANADA: Sorry to say this but we had very long delay on delivery in Canada these days and it takes even two months occasionally when you suffer from bad luck. In the case of trouble you have to wait two months(plus a week) before having me issue fully refund. If you are in Canada consider using EMS for shipping method, which is traceable and very fast(3 days or so) but it costs 20USD instead of 6 :( Let me know if you want to use EMS.

The converter looks like the pic and includes detachable coiled 4P4C cable. The cable supplied with the converter, it is a 4P4C telephone handset calble which differs from original Apple keyboard cable.

USB-USB converter
I ordered five MAX3421e chips at an Aliexpress shop for USB-USB converter, it will take several weeks to come up to me.
After got those chips I'll assemble the converters and decide its price.

Thanks.

Yes, just post here or PM me.

I have to decide the price later due to final cost calc, but you can cancel it if you don't like the final price.
The price will be around 40-50USD, probably.

I have a leopold keypad that doesn't send true numpad scan codes, I'm thinking I could theoretically fix that with your converter yes?

I think USB-USB controller will cost around $50 and $8 for shipping, not final price though.
I ordered USB host chips from China but not receive them yet, it will take more a week or two. After getting the chips my production process will take a week.

BTW, Kinesis has another viable option to think about, this controller replaces Kinesis original MCU and allows to upload custom firmware.

I think Teensy 2.0 or Pro micro is also small enough to accommodate it inside of the keyboard. And way cheaper than my converter, unfortunately :p

If you still want my converter for some reason I'm happy to sell my converter definitely. I can assemble the converter without USB or/and PS/2 connector if it is useful when you install it inside the case. It costs $25 + $7 for shipping.

Do you think it would work with a Poker II? I don't really know what a keyboard "with fancy functions" means :D Would there be a way to check this somehow?
The Poker II is not PS/2 compatible so I can't use your USB<>PS/2 converter on it... but it would be perfect if your new USB<>USB converter worked!

Poker II uses NKRO mode I don't think USB to USB conveter works with it at this moment.
But I believe firmware can force it to work in 6KRO mode with future update.

What I meant by "fancy functions" are NKRO, media control keys and system control keys. The converter doesn't recognize those keys.

Interested in a usb-usb converter. Primarily interested in using it with RF87 on OSX. There's an issue with he keyboard where if I wake the computer from the keyboard, keyboard doesn't register after that. Any chance someone tried it with an RF?

I can't explain everything in detail here. You have to read TMK documentations first and the docs won't be enough, you can use google to get further detail.
https://github.com/tmk/tmk_keyboard/blob/master/doc/build.md
https://github.com/tmk/tmk_keyboard/blob/master/doc/keymap.md
and read converter's README of course.

And optionally also check Wiki.
https://github.com/tmk/tmk_keyboard/wiki

It may take long unless you have experience with AVR, but take time to learn if needed.

EDIT: Also check the first post of this thread.

Thanks, Hasu. I think I figured out what my issue was. (As you mentioned, those Xtals are indeed tricky to install.)

My NeXT keyboard is alive! My board (Part no. 192.00) has the ANSI layout, where the layout in TMK is ISO. I'm noticing a few weird things (keypad layout is different, "Alternate" key doesn't register at all) so I'm going to break out the debugger and see how things are different. It's likely I'll have a push request for you.

One side question: I read the schematic and I thought I installed my LED with the correct polarity, however nothing is lighting up. Should the LED light up on boot or does it only light up for certain events?

Thanks,
U47.

Some use it as CapsLock indicator or debug, others don't use at all.
Next converter doesn't use so you can use it for anything you want.

Hi, the usb to usb converter seems great. How much would it cost to send one in Europe (French) ?


Same rate for all surface of the globe.

Shipping and Paypal fee: $8USD (add $3 per extra converter)

Thanks

Do you have any plans at any point to do a Bluetooth version like you did for the HHKB?

I've had a plan kind of that, you can connect both keyboard and Bluetooth dongle to the converter via USB hub at same time in theory, and you can give it power supply and Lipo charger(from sparkfun or adafruit? or just use power bank in the market) to make them wireless.
USB Host Shield libaray already supports Bluetooth dongle and HID luckily. My concern is MCU flash size, TMK has bloated its size now I'm not sure the code fits in 32KB.

I don't a plan to design new hardware but USB-BT conversion is possible with this USB-USB converter + BT dongle + USB hub + power bank, I think. Too big and clumsy? :D

yes, you can change keymap.

That would be awesome to have one that was less clunky.  So far, the only things I've seen are this USB2BT and what you have.

If I wanted, I could use your USB to USB with a Bluetooth dongle, battery, and hub on any 60% board?  Or does it only have to be with specific boards?

Yes, you could do with existent TMK USB-USB converter, no specific hardware is needed for this, just firmware development is required.

If keyboard has hub like HHKB Pro2 you can plug dongle in it, it would look like this.

The firmware development would be for the bluetooth, correct, not the keymap, correct?

Yes,
the library seems to support only bluetooth HID host role, but we need device role and will have to make it.

What an awesome project! I got my self Tandberg TDV-5000 with following connector:


Is it possible to use it directly with Mini-DIN type Converter ?

No, you can't use it directly because that pinout is not PS/2.

Okay, thank you for answer. How about PCB rev2.1 - can it be used for this pinout?

Assuming pinout diagram above displays female connector(socket), any of pin configuration jumpers on the PCB can not give GND connection to pin5 in the diagram unfortunately.

My converter PCB's pin configuration jumpers looks like pics below. In case of Mini DIN6P connector DIN1, DIN2, DIN3, DIN5, DIN6 and DIN8 are wired to each connector pins. Pin5(DIN6) has no jumper for GND connection as you can see. Other pins can be connected with jumpers(for Next) somehow.

I'm on the road and away from home unexpectedly, shipping for some of orders will be delayed until Monday. And I cannot check and reply to inquiry mails until then.
Thank you for your patience.
