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.

Subject says it all. IC7 on an A3010/A3020. Readily available in DIP, but not SOIC as used here.
I've just had one fail (output levels are weirdly 4V not 5V) causing "No keyboard present" failure in RISC OS... boo! (Already replaced the decoder this feeds, so I know it's not a loading problem)

Actually wondering if I can get away with a 74LS368 here, since the enables are hardwired 'on'.
(74LS368A is available!)

I would say yes, the 368A looks compatible if the enables are both 'fixed'.

74HCT366 also looks readily available and should do the job.

Thanks all.
I put an HCT14 in place for now - it was "close enough" (just VCC needed strapping over) and I had one to hand :)
