Well it is this version of the Dragon 32 Motherboard: http://archive.worldofdragon.org/index.php?title=File:Dragon32_PCB_Top_(PC10087_Issue5).jpg Mine had a few labels on some of the chips. It has Z105226 on a stamped piece of paper just above IC26. It had a long sticker with a handwritten AT on it ...

Thanks Zephyr, and apologies for the confusion caused by absentmindedly posting on the wrong thread!

Thanks Robcfg, that certainly a good tip that I'll try.

Hi Zephyr. Yes the warranty stickers are all still in place; so consequently I'm not yet sure which board is in there. Before I can open it up I should really check with my brother in law (whose machine this actually is, it's on long term loan to me) to see if he minds me opening it up with a view t...

The thing is Alastair I only got I/O errors when the tape was badly adjusted. What's been happening recently is that the loading process has been working fine, I have seen the loading screens of several programs, but midway through the cursor stops flashing, and the screen freezes. I know they are d...

OK< thanks sixxie. That's great.

I worked out that the CBM basic P shift O etc doesn't work on the Dragon. Is there a way of shortening the commands? I know Acorn equipment used the fi...

Thanks Alastair. That combo seems to work quite well when loading from my iPad.... up to a point. It all seems to be loading and then the cursor stops flashing, the wav file ends, and nothing happens. I think I worked out why, but posted it on the wrong thread, apologies for that! Please see here: h...

Thanks sixxie and zephyr. I shall certainly try those, and report back. At the risk of sounding a bit thick; should I put line numbers with those commands? The Dragon is a new system to me. I noticed that ? is short for print, the same as CBM Basic V2.0 (also by Microsoft), does that also extend to ...

Still nothing will load. It gets so far through the process and then the cursor freezes, the .wav file ends, and the screen does not change. I tried Chuckie Egg, Airball and Frogger. I think I have found the problem though - BAD RAM. When I type ?MEM, I get 8492, which is rather lower than I was exp...
