Hi Rasteri, is there anything special you have to do to get the HIDMAN to work with Amstrad PC1640 apart from putting it into XT mode? You sent me one through last September but didn't get a chance to try it until today with this machine. I have updated the HIDMAN's firmware to 1.1.6, connected up and power on, put it into the XT mode (red/orange). But I am then finding that weird keys are being output to the machine: https://photos.app.goo.gl/4eHwBXHGpts4cVVBA seemingly randomly. I've tried it on a second 1640 and finding the same. Tested on a newer PC via PS/2 and works ok there. Any ideas? Thanks, Will
