Re: Hello from a rather wet Manchester

Welcome, I guess you have been over to http://bbcmicro.co.uk to see what is new and what you might have missed. If the drives work, you can probably use "tape" (phone/computer) to copy a few bits to disc, or maybe a gotec/mmc for more.

Re: My main beeb from the 80s has died

Capture is no good, I tried a working beeb and it has a few sensible bytes then a patch of rubbish, few bytes, rubbish... The decode isn't helped by my compiler not understanding positional arguments (1$, 2$, 3$) but in this case, a small change and removing them fixes the display. I'll try some dif...

Re: What is (zp,X) actually useful for?

You would still expect X=0 or at least that the instruction to known which stack.
It feels like it looked useful and as noone else had programmed the 6502 it was a reasonable choice.
Shame they didn't extend it in the C02 to (zp) and (zp),x, like they did with store 0.

Re: My main beeb from the 80s has died

I have written a D2XX reciever which seems to work OK. I have written some tsearch functions, removed the arg parsing (hard-coding for now) and compiled 6502deocde with VS. I can't get it to work though, so there may be something wrong that doesn't show as a warning or error. I also couldn't tell wh...

Re: What is (zp,X) actually useful for?

I have only used it a few times and probably half of those had X=0. There have been a couple of times when I have had to add to one of several lists and using (,x) and inc,x was more efficient.
I suspect that they may be more useful to a compiler or a virtual machine like sweet16.

Re: My main beeb from the 80s has died

I've written a simple d2xx reader and it reads nothing slowly with beeb off and something quickly with beeb on!
So, the board seems to be working, but maybe an issue with the various USB libraries and drivers I have stopping the COM port from showing.

...Double check the EEPROM contents are still there... Otherwise windows should install the FTDI drivers and it should just work. Did you test it on a known working machine - you should be able to get comms with BASIC and any terminal program? The C# reader isn't shared but I can send you a copy. P...
