I found a repository on github that is supposed to be a mirror, it looks like it has the common directory in the exp25 folder!

Re: Spartan 6, 5V tolerance and PS/2 Keyboard
I have just tested this with a new keyboard CIT KB-2106C, a USB keyboard with USB to PS/2 adapter. It works and the voltages are around 4V, just under. I will use this from now on.

Re: Spartan 6, 5V tolerance and PS/2 Keyboard
Using the BAT54S tied to 3.3V and ground looks like a good way to protect the Spartan 6 i/o pins.azesmbog escribió:Умные люди ставят защитные стабилитроны и не задумываются о проблемах электромиграции...

Re: Spartan 6, 5V tolerance and PS/2 Keyboard
I will copy my answer from Facebook here: PS/2 devices connecting to a host are assumed to be open collector, so they either pull the signal to 0V or float. PS/2 pins at the FPGA are internally pulled up to Vccio (3.3V). A proper PS/2 keyboard should not pull up their outputs to 5V, as this is done...

Spartan 6, 5V tolerance and PS/2 Keyboard
Hi, I have seen a couple of threads on the ZX Next forums discussing the issue of the Spartan 6 not being 5V tolerant. I noticed a while back the we have 510 ohm resisters on the inputs of the ps/2 keyboard on the ZX Uno and no further level shifting. I measured the the voltages either side of R8 an...

Re: Creating mcs file

Hi, I have just finished building a zxuno board it seems to be ok as I tried flashing the prom with just the test23 core and I see the initial screen waiting to load the BIOS. However I cannot find the generamcs_multiboot_Q32.bat file in the repository, so cannot create the prom.mcs file. Can someon...
