Let me clear up the minor confusion here: Roy wood wrote:

Well, here's the deal: The cables I used as a jig were from a PC that had them wired correctly, or I should say, logically. They used the same system i did, a piece of ribbon cable and a press-fit connector on both ends. If you build a serial cable for the Aurora that way, it's wired correctly. Surprisingly, almost all PCs have it wired 'wrong' - on the Aurora side the pins alternate row to row as the pin numbers increase (which is the standard numbering for this kind of connector), on the DB9 side, they go first one row, then the other, again standard for this type of connector. On the PC they have to go 1-1, 2-2 etc, which means that you cannot wire a flat cable directly as in that case the pin numbers do not correspond on the connectors, due to different numbering standards. because of this, you CANNOT use PC serial board cables on teh Aurora, with very very few exceptions. This should not be a problem as it's very easy to do your own using press-fit connectors, and that was the goal. Incidentally, PC manufacturers use cheap sweatshop labour to solder the connectors by hand :( Ffibys ;) wrote: > Maybe they were more than one versions of Aurora? No, just the one. There is going to be a Special Edition soon (assuming I don't just keel over one day with the amount of work i have to do these days). the reason why the last 25 or so were not assembled yet is that I plan on putting a half meg flash ROM onto the board so that SMSQ/E can be booted directly. It's a minor mod if you are building an Aurora from scratch, but not on an already built one.

You should consider yourself lucky that I only use my powers for good ;) Tony Firshman wrote abut the extra 4 pins on the Aurora ROM port that nothing uses... Well, there is, hopefully, soon going to be somethiong that uses them, namely a small Ethernet board... assuming again I don't keel over. Not far from it at the moment as I have the mother in law of all sore throats and sinus inflamations :( Nasta _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
