How about the AY unit sit back and listen to the thousands of files available and while away the hours.
No seriously you have a bonny little set up there and what with the Xpand and all the software that's been created for it I wish you many happy years of zeddiness.
Also I think you will find games especially Bob's stuff much more enjoyable with the Memotech.
The only other suggestion I would make is to use a regulated 9V 1.5 to 2 amp power pack in the interests of keeping things cool under the bonnet so to speak, the meagre heat sink gets pretty warm with nigh on 7-8V being dumped by the regulator as heat energy.
Does anyone slightly lie about how much money they spend on stuff to their better halves? I normally divide by 2 in my head when explaining what I paid for something that to others may be utterly pointless!

LIE!!!
You must be joking I tried that just once and learned very quickly that for the sake of ones health it's best not to tell fibs to a retired Burler and Mender from Salts mill, they have very strong arms and a powerful punch.
These days I just say it's something for car/house/gas boiler etc.
I am the happy owner of a zx81, a zx81 chroma interface, a zxpand and a memotech keyboard. Till now i have connected chroma interface at the back of zx81 and zxpand at the back of chroma interface and all works fine. Furthermore i want to connect the memotech keyboard. Is there a specific order to connect the three of them? Which first? Which last?

Ok so put a wee plastic key-way/spacer in the gap, so that should be good now.
Still no go with the keys. I realised the Newline/Function key also is not working. So that makes 5 keys (H-J-K-L-NL).
Seeing there are 10 keys in a row, could this be a keyboard matrix issue? Maybe something on the PCB?
Funny, I wanted the Memotech keyboard to safeguard the membrane failing oneday (also have a membrane replacement stored away), but the keyboard has the failing keys issue! haha

I thought i'd respond to this, the ZX81 sends 5 signals sequencially and reads the result on the data-pins (while it is not performing a memory request ~o~ ) , those 5 keys are on the same data-pin, therefore a bad connection would be the case.

Thanks in advance,
I don't think there will be a problem if you place the Memotech keyboard interface between the ZX81 and the chroma interface.
Standby alert
There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.
