Re: Complex Programmable logic CPLDs

It should be noted that (to my knowledge) the only hardware dependent things used directly and not through an OS driver are the RTC seconds counter in the 8302 and the mode control register in the 8301. Not quite ;) During compatibility tests of the Q68, Detlef found that few (two?) games access th...

Re: Psion Chess

Sorry I was a bit unclear - I didn't mean to say that Psion Chess brings it's own OS.

Please let us know if you can actually reproduce that. As far as I remember, Psion Chess completely takes over the machine, replacing the OS.

Re: QDOS-GCC How to run the binaries?

I think that the xtcc marking is the internal way QDOS zip/unzip stores the data space, so that makes sense. No, the XTcc business is only added to the code when the QDOS ZIP source is compiled on another platform (effectively replacing the QDOS specific header functions). The header information is...

Re: QDOS-GCC How to run the binaries?

I was unaware also that QL unzip knew about xtcc headers/trailers. Good to know. But is a special option is required on the compression side, I doubt it us used too often - but what do I know? Hi Norm, I don't think compression requires a special option on PC side, if it is a XTC68 or QDOS-GCC cros...

Re: QDOS-GCC How to run the binaries?

The binaries have an xtcc record at the very end which holds the dataspace value required. But how to make them executables with the correct dataspace? You need my Assembly language eMagazine, Issue 6 and my xtcc utility, code at https://github.com/NormanDunbar/QLAssemblyLanguageMagazine/releases/d...

Re: TF Services Interfaces and BBC Micro:bit

The Q68 has a I2C interface on tge board, which I have fitted a SIL header. All Tony's Inferfaces can be used. The only problem is the lack of external I2C connector when the Q68 board is fitted into a case. The real only problem is that no driver exist yet for the Q68. Unless I missed them. I thin...

Re: FGPA Anyone?

In the meantime a free scaler was released and another cycle accurate 68k core was revealed for another core, maybe I will try these one day. Are you referring to the FX68K core? I had a brief look, but was not in the mood to manually convert System Verilog to Verilog, which is required for my synt...

Re: Q68 Ethernet

By the way, the CP2200 chip is well suitable for the QL, it has a directly compatible, 5V tolerant 8 bit bus interface. Should Q68 ethernet software be released, the QL can benefit.

Re: Q68 Ethernet

Does the Q68 have any ethernet access? Or is anyone looking at providing ethernet access? Good and bad news. First the good news: Last summer I have already accessed the internet with the Q68 over ethernet. I successfully used ICMP ping, TCP echo, webserver, textmode webbrowser, POP3 email. This wa...
