Forum rules
You're welcome to trade Acorn-related stuff with other forum members here - the rule of thumb to follow when trading, is that items or services offered should be of interest to our Acorn community. Do NOT use multiple accounts - please trade with your regular (and only) forum account. If you're giving items away, please make it clear if you would be unhappy with the recipient selling on some or all of the items. Similarly, please ensure that the giver is comfortable with you re-selling items you have accepted as a gift. We cannot be held responsible for what happens in these trading forums or for deals done via PM. This must be done at your own risk. If you aren't comfortable with this - make the trade via an alternative site which can apply safeguards of their own. Be sensible - if someone approaches you to trade via PM who is not posting in the public forums, this may be a sign that they are not entirely what they seem. Please report it to the moderators if you receive an unsolicited message from anyone suspicious, so that it can be investigated and hopefully stop anyone being taken advantage of. This forum is not for advertising items you have for sale on ebay or other third party marketplaces.

I thought I'd post this here, as I wasn't sure where else would be relevant . . .

Rummaging through some more of Dave Moore's (Arcadian) BOXES, that he's entrusted to me, I found some part built Slogger Pegasus boards - 7 in total.

5 of them are issue A boards e.g. the same as the ones in this thread - but different in that they don't have 'curly' tracks and have one extra jumper (I'll see where its connected too later). See photos below.

2 of them are issue B boards :shock: Not noticed these before. No 'curly' tracks, again, and more extra jumpers. Some work to do here to see what they're for :D

Here's an annotated schematic (courtesy of Prime) showing the added features of Pegasus board Issue B.

The quality is just good enough to see the details.

Edit: The position of the RAM has also changed to the left hand socket (IC3) - so there may be another schematic change.
Edit: The DFS is now fitted in IC2
