Re: Baildon Electronics IDE Interfaces - Replication

I'll order 10 of these. So if anyone would like one - just let me know. If someone could carry out a sanity check, please. I'll take one if there is one spare. Seems to be a slightly odd order of address lines out of the shift registers, would be better if you re-ordered to make the shifting out of...

Re: For Sale: IDE Podules again

I do have some more PCB's on order, but I'm making no promises as to when they will be available.

I'm NOT starting a list, please don't ask, they will be listed on the forum if/when they are available.

Re: IDE interfaces - hardware details

The two jumpers on board, one selects between ZIDEFS or other, when set to other, the other jumoer switches between IDEFS and SIDEFS (of little use to anyone, but left in for extreme cases of 3 cards fitted to one machine) Try changing the jumpers, do a full reset, check the module list, see which ...

Re: Combining sprites in RiscOS

I can't remember how to combine individual sprite files into a single file, and the user guide is not much help. Does anyone here know how to do that, preferably using the command line? Command-line, no idea. Easy enough to do using the GUI, open one file, open another, then save the sprite from fi...

Re: A3000 IC2 - keyboard/mouse controller

The two wire serial interface is the same as the usual keyboard connector on the A3xx/A4xx etc. machines. So you can, if you have one, use a normal Archimedes keyboard. Flip link 16 and wire a din connector onto LK3. You can then also use one of these - https://stardot.org.uk/forums/viewtopic.php?f=...

Re: Difficulties extracting zip / adf files to DOM

If all you want to do is play games from adf files, then a gotek may be a better option, as I understand it it will read adf's directly from a USB stick.

If either/Both of the new boards can be flashed with the newer IDEFS module, then surely 8 partitions is also feasible ?
The boards I produced are not hardware compatible with any Baildon cards. IDEFS software module don't just magically work with any IDE hardware interface.

Not sure what a DOM is, or what it's for, but I'll take that too please.
DOM = disk on module

It is solid state module which emulates a hard disk.

So the interface + DOM becomes a plug a nd play solution, no further hardware required to have a functioning hard disk.

Re: IDE podules - 8 and 16 bit versions

I don't understand the difference (benefits) between an 8 / 16 bit version (hardware-wise). It's mainly a physical restriction. The podule bus on the original Archimedes range was on a DIN41612 64-way connector, which had a 16-bit databus on it. When the A3000 was introduced Acorn included an inter...

The collision detect circuit uses half a LM319 - you need the other half to handle the incoming clock and received data, so there's no additional silicon required there.
