Happy 40th birthday to the #Sinclair #ZXSpectrum 🎉🎉🎉 The computer that lead me to a career in software and for what came after. And I still have it! It does need fixing though. 🤒

After a long wait for more boards due to a lockdown in China, I have been able to make more #minstrel4th usb keyboard interfaces today. Please DM if interested. #Forth #minstreltheforth #jupiterace

Great news for anyone with (or anyone interested in) my Minstrel keyboard adapter. I’ve finally solved the issue of not all keyboards mounting. Seen here with a regular Pi keyboard. #minstrel4th #jupiterace #minstreltheforth #forth @jubrunk

It turns out that 'relisting' an item gives a different item id. So here's the new link. I didn't see a 'revise listing' link after the last of the first batch sold. Does anyone know how to relist an item and keep the same item id/link? ebay.co.uk/itm/284679639077

Just soldered up the Backplane5 addon for my Minstrel 4th,so that I can use both the Jester Ace and the USB keyboard addon,on my Minstrel at the same time! @shieladixon @JesterAceSD .Highly recommend both addons! Shiela's awesome keyboard addon makes using the 4th so much easier!

It's time to put together the Jupiter Ace kit. Classic British microcomputer with a focus of Forth. The kit came with a coloring book and balloons which is nice. I have to dig through my socket supplies though as only some sockets were supplied. #RetroComputing #NotAZX80

Is it possible to deadlock the ULA in a #sinclair #zx81 ? #RetroComputing

Thanks all for the great suggestions! Looks like asmx is perfect for my (simple) needs. I can now transpile Z80 assembly into Forth machine code words. 😎

Does anyone know where or if I can get hold of 8x256 byte dual port SRAM ICs in a DIP package? Cypress seem to have manufactured them but no more I think. #electronics
