One of the cool things about the #Minstrel4th is the fact that its #ROM not only contains the original #JupiterACE ROM and an Enhanced JupiterACE ROM by @nihirash (which enables program load via serial I/O amongst other things) - no: there are also #ZX80 and #ZX81 "compatible" #BASIC ROMs available on the additional banks, all selectable via jumpers.

The ZX81 compatible ROM works well enough to run "Flight Simulation" by Psion Computers.

EDIT: Oh, and it runs the ZX81 version of "Mazogs", of course ...

What will not work is anything that uses non-standard screen and keyboard routines, as the hardware of the Minstrel 4th is slightly different from the original ZX81. Still, it's a nice extra I didn't expect.

Done with the #Minstrel4th and it's #alive 🥳

I still have the Tynemouth clocked serial module to finish so I can easily transfer data via serial I/O, but that can wait until tomorrow.

I'm so happy that this replica of the original #JupiterACE is working - can't wait to load some classic games tomorrow!!

Started building my #Minstrel4th today but ran out of high precision IC sockets ... *sigh*

I spent a bit of time playing Valkyr this evening, and recorded my efforts.

This is the version from Geroge Beckett with fixes for the Minstrel 4th and RC2014 YM2140 sound card addressing.

This is a slightly loaded Minstrel 4th with a Jester Ace SD reader, Shiela Dixon's USB/serial keyboard interface, the RC2014 YM2149 sound card and Tynemouth Software's Boldfield compatible joystick card all attached via a RC2014 Backplane 5.

All cards used in loading and playing the game.

It's interesting that everything apart from the YM2149 is now standard on the Minstrel 4D Turbo.

This joystick card has had a Royal Mail journey worthy of an X-Factor contestant.

Put together yesterday and tested in the Minstrel 4th. Works a charm.

However, space problems with the RC2014 means I need to rework the Pi Zero Serial terminal and lower the card height to fit all the cards on.

I have a plan.
