Ah, shows you learn something new every day. The 8749HC is user programmable, but only once, for low volume prototype runs. I have the 8749HD with the quartz window, which are programmable multiple times. Hmm, creating Hermes chips is relatively easy if you have the programmer, did one just yesterd...

Hi,

The added components on the chip are to implement the CAPSLOCK_LED circuit, which works with 8049 and 8749.

So from the IPCVER$ function,the IPC is a 8049.

Hi, Thank you for the STL files, I got a quotation from Treatstock, which is a 3D Printing Company that outsources 3D Printing work to third party printers, which was quoted as $33.75 (they use US Dollars for payment) I could get a proto-type print done. The list of parts indicates the power supply ...

Hi, If the STLs are not available, I could have a go at producing a similar design. I have done a little basic design work on a simp.e cu ic Q68 case, not with any QL Styling. I will see if I can enhance it bit. You fancy sharing what you have ? Nothing really, only a copy of the current Q68 case. ...

Hi,

If the STLs are not available, I could have a go at producing a similar design.

I have done a little basic design work on a simple cubic Q68 case, not with any QL Styling.

I will see if I can enhance it bit.

Sorry its been sold earlier today.

Hi Tom

Thanks for the clarification, I was going add an Oqtadrive in next to my QL-SD, if I can map MDV 1-8 on the Oqtadrive, that would be great.

Hi Here is an update to the next batch of the Q68. I have submitted and paid for the the next batch of Q68 boards to be manufactured and have the SMD conponents machine soldered. Unfortuneatley, there is a 25 week lead time on component deliveries, this means the completed Q68 PCBs will be delivered...

Hi, The Joystick CTL functions, as in a QL are hardwired to the defined CTL Port. But an emulator could have user defined joystick functionality, is this possible? The joystick is effectively emulating 5 keys, so it is possible in theory, but it would require changes to the format of the ini file t...

Hi

I have done a updated PCB, with SMD components, which is 3rd on my list of jobs...
