SE Basic IV 4.0 Anya

But what is "Var" thing anyway?...

Sorry for the late reply. It's just a copy of whatever is in the variables area after the program. I'm making good progress on SE Basic 4.1 now and have added the TRACE, SCROLL, and SPEED commands. The latter replaces two commands (FAST and SLOW).

Small update to version 4.0. I've backported the new keyboard mode from 4.1 and juggled a few characters around to support the Chloe 280SE's keyboard.

Updated to v4.0.7 with experimental Kempston mouse support:

Somehow missed this topic, found it only today. Despite already knowing about OpenSE Basic, didn't know about this fork. Seems to be a great project. And it supports 8-bit encoding, just like OpenSE Basic does. Good luck in continuing developing it.

Playing with SE Basic IV v4 on my TS2068 (in normal mode):



Machine boots as TS2068, but after OUT 244,3 command it switches to SE Basic IV

I didn't know that I can enter hexadecimal numbers here

Like poke &ff00,&ff

Nice

Interesting, but I'll stay with v4.0.4

P.S. I want to build simplifyed "ZX Spectrum SE" clone with v4.0.4 onboard and I understand that most likely it's a decade long jorney

Some clarification on which version of SE Basic to use for what.

If you want maximum Spectrum compatibility, use SE Basic 3.2 (https://zx.itch.io/sebasic3)

If you want a high degree of Spectrum compatibility, plus an 80 column mode, use SE Basic 4.0 (link above).

Version 4.1 was a failed attempt to refactor the code base that introduced a number of bugs. It's really best to avoid it.

If you think you might be interested in developing for the Chloe 280SE microcomputer, use SE Basic 4.2. It has no Spectrum compatibility. It also requires an esxDOS compatible OS kernel (https://zx.itch.io/sebasic4)

Good to know. Thank you!

You're welcome. It's also probably worth noting that SE Basic 4.2 is entirely disk based and it *might* be possible to get it to use TR-DOS instead of esxDOS. It avoids all the TR-DOS address traps (because the divMMC emulates TR-DOS). It depends on if TR-DOS will work with the SE Basic 4.2 ROM, which is radically different from the Spectrum ROM.
