Re: IDE interfaces - hardware details

Does the output of the DeviceID program look sensible (does it match the size of the device you are using?) With zidefsdrive 1 and zidefsdiscs 1 and zidefsdrive 4, when you run the partion program it should allow you to set the size of the partition. Then reboot the machine (prefreably a power-cycle...

Can you configure a couple of pins as outputs? So you you could use two outputs as column outputs and have a 2x6 matrix of switches for up/down/left/right/fire1/fire2 for 2 players. Probably need some diodes to avoid gosting effects.

Are you looking at the right key, the "/" key in your original keyboard matrix picture, is the one on the numeric keypad, so will probably be on the other side of the blue link. The "/?" key is on R1 and C8.

Do these work on a3000, and support biggish hds ?
Both would work on an A3000 (the only machine with an 8-bit internal podule slot and an external 16-bit podule connector)

On a RISC OS 3.11 machine (e.g. A3000) they support up to 2GB of space (4 partitions of 512MB each)

Re: EUPURS and AP5 Cable(s)

As discussed before (but I still haven't tried it), if you want to stick to TTL levels and avoid the RS-232 voltages and the UPURS clamping components, you will probably need to invert the signals from the serial adapter - viewtopic.php?f=3&t=10586&p=136573#p136534
