Why not take the opportunity on this auspicious day to power up your #Minstrel4th or #JupiterAce (or #EightyOne emulator) and learn some #forth. It's easier than you think, and your reward is being able to write fast and compact code - github.com/markgbeckett... #maytheforthbewithyou

If you need some more festive decorations for Christmas, why not power up your #JupiterAce/ #Minstrel4th and run AceSnow (inspired by Xsnow which adorned my Unix workstation in December for much of the 1990s). #retrogaming github.com/markgbeckett...

Having disassembled Colin Dooley's port of #centipede for the #JupiterAce (and #Minstrel4D), and discovered an unused spider graphic, I've been working to restore the spider feature and (hopefully) fulfil Colin's vision for this great game! I will share a TAP version soon. #retrogaming

I have ported Tree Forth/ ZX-Forth from #zx81 to #JupiterAce/ #Minstrel4th. With no display generation to worry about, #Forth runs amazingly well on Minstrel 4th. It can find all primes in first 500 integers, using Sieve of Eratosthene, in well under a second. #RETROGAMING github.com/markgbeckett...

With help of @robertprice.bsky.social , I've connected my Timex Sinclair 2040 printer to my @tynemouthsoftware.co.uk #Minstrel4th. ZX Printer was well-supported by #JupiterAce with lots of software, which I'll be exploring. www.robertprice.co.uk/robblog/usin... www.jupiter-ace.co.uk/sw_zxprinter...

The sleek Jupiter ACE resembled the ZX81 and the Spectrum, but was discontinued by 1985, without ever having its own version of Football Manager.

`store` and `load` implemented, using #JupiterAce code, as it is more robust than ZX-Forth original. This means you cannot load screens from #ZX81, though you could load screens into Ace Forth (if you can think of a use for that). With that done, I can now start coding! #minstrel4th #retrogaming

The Jupiter Ace (1982) used Forth instead of BASIC. Would programming in schools have changed if Forth had been more widely adopted? Who preferred Forth? And WHY are these so madly expensive now?

Did I mention the Minstrel 4D (#JupiterAce Compatible) computer kit currently has £72 off (inc UK VAT)???
I'm mostly sure I'm making a loss. But times are hard and I need to buy Jelly. www.tfw8b.com/product/mins...
