Minstrel Keyboard overlays already had the ZXpand keywords on them?
Paul Farrows flicker free ZX80 games can use the Kempston interface, press C to change the control type on the main screens.
INKEY$ command to read the keyboard will also now benefit from joystick support as the INKEY$ function is also replaced in the overlay ROM. The Minstrel ZXpand can be configured as to which key will be pressed for each direction using the CONFIG command. Hey ZX81 Adventures, can we have joystick support for Tut-Tut?
Minstrel ZXpand will be available either as a kit with pre-programmed chips, or fully assembled. All parts are standard 0.1" through hole, with the exception of the SD card socket. I'll solder that to the PCB on the kit versions ready for you, so no surface mount soldering is required. They come with a replacement ROM for the Minstrel 2 or Minstrel 3 which contains the ZXpand ROM code. There are three versions on there, one for ZX80 4K BASIC, a special version for ZX80 8K BASIC (which does not use slow mode for CAT), and a ZX81 version.
Minstrel 3 listing, so you can now build the whole thing as one complete matched unit. Looks rather splendid, doesn't it.
Available from my Tindie store now (← that was the link to go and buy it).
Suitable for the Minstrel 2 and Minstrel 3. Not suitable for anything else. Really, I mean, it just won't work. I'm not just saying that. It won't, the firmware is different, the overlay ROM is not on board. The RAM is not there. Half of the decoding logic isn't there because it's already on the Minstrel board. Listen...... No, look..... Oh, whatever....... No, it's clearly not wide enough to fit behind an Amstrad CPC 464............No, it will not work on a TS1000 (or a T-1000) or a TS1500 or a Lambda 8300, or a Commodore PET or an Altair 8800 or on anything else, and let''s be absolutely clear here, even if it looks like it might fit in the hole in the back of the case, it still won't work.................OK, OK, I admit it. If you disable the ZXpand section completely, then only the Kempston joystick interface would probably work on a ZX81. But that's your lot mush.
