Much has been said about that desoldering station, all positive.

I can't remember if the Zicon shows the register values or not, it's been that long since I used it.
I would be very interested if it did.
Just checked - it doesn't.. pfft. It's one of those oddball things that's totally useless, until you need it.

Re: Z80 Protocol Decoder

Sorry for the thickie question, but is the protocol analyser like the Zicon logic analyser by any chance? Yes, in that it works as a "inverse assembler" (like Zicon and certain HP logic analyzers). But it improves on those in two respects: - it requires fewer connection (just the data bus and a few...

Re: Anyone remember a four colour ballpoint pen plotter?

I've got a Tandy one on the shelf. Model CGP-115, with spare paper and pens. Serial and parallel ports, uses an ALPS DPG1302 plotter mechanism. Always liked the idea, but it's quite slow with text. 12CPS - imagine listing a 48k BASIC program (from, say, a Speccy) - it'd take decades.. Makes an inter...

The Atmos keyboard has a really nice feel to it despite it having a membrane. It's the same as the Oric under the hood, save a bug fix or two to the BASIC.

Re: Elan Enterprise

uIDE is a really simple interface which relies on the IDE device to do the heavy lifting. If there is already a driver that supports an IDE device, all you need to do is configure the address decoding chip (I'm cheating here - it's an 8 bit comparator) on the uIDE to match the I/O address in use by ...

For mass storage you might try one of these: http://www.cpcwiki.eu/index.php/UIDE_Universal_IDE_adapter_cards_for_Z-80_computers So far they are only in use on PCW computers and one other machine so I'm keen to get them running on others.

Re: Worth Taking a Look At

EuroBeeb uses the AcornBus as it is derived from the System 1 (or2, 3 not sure). Card would be electrically compatible - but may need some ROM hack on the processor card to support it - I doubt it, though!

Hey Mark, do you think those cards are Acorn System cards?

Nah, I was the spotty kid with the faded tee shirt hacking hand assembled code on a ZX81 while my best friend (who I was very envious of) turned out wonderful, flicker free, colourful, musical and fast programs on his Model B.

He had several very nice jumpers.
