Re: ZXpand Maths prob and a display problem
Hi Moggy hmmm interesting! SO, a Victorian ULA in NedZed as well!... though NedZed's display is ok - FredZed gives me a slight warping at bottom left of crt screen and and occasional black snow drift horizontally across the screen (none of my other zeddies do this) - I think FredZed has a Ferranti b...

Re: ZXpand Maths prob and a display problem
NedZed.jpg Thanks Rich and Moggy! (hope you are well both incidentally) - yes, well I've cast warranties to the wind and have now opened NedZed and do find a most peculiar arrangement inside (that I've not seen before but have distantly heard of) and so here it is - You both have the explanation so...

ZXpand Maths prob and a display problem
Hello wonderful people Hope you are all well. Managed to have some quality time with my zx81s over the holidays and while at play noticed some interesting issues - some of which jigged a memory of an old problem with some zx81s back in the 80s but I have truly forgotten what the issue was. I have ru...

Re: MT keyboard enquiry
Hi Moggy and Mark! Thanks both for the very useful info, I hope I get another opportunity to make use of it! As I was reading your comments I confess to getting that gut-wrenching, sinking feeling (which I could go on to describe in much gorier detail) of having very stupidly missed a series of oppo...

MT keyboard enquiry
Hi all, I recently saw a spate of Memotech keyboards going on ebay. While I watched the auctions with interest I decided not to get involved as this keyboard attaches to the zx81 port for the display buffer thingy (hmmm...that's a phrase I've used three times this week). Although the buffer the atta...

Re: AY course
:D I instinctively reached for the 'like' button for the posts above ☝ - but there doesn't seem to be one... Sadly (especially for those around me), I extended my music education at the expense of properly probing the dark underbelly of Z80 programming. I regret that now as I didn't turn out to be :...

Re: AY course
Ah! Sir M, blessings! I shall go prospecting through that thread, it looks very absorbing (so that's this weekend sorted!). I did connect (couldn't resist connecting) the zxpand+AY to a Roland SH201 synth and the output is quite awesome - how wonderful it would be to be able to reverse the flow and ...

AY course
Just to say hello! I've been 'away' - which is code for my employers asking me to actually do some work over the last 18 months, at not inconsiderable inconvenience I might add. I missed the bonhomie of this forum and spending blissful hours with the zxpanded zx81! Returning to where I left off I'm ...
