Re: Where can I find a 5 pin din to twin Jack plug

Even if you have the DIN connector connected to a ZX81: the voltage levels at the DIN connector are much too low to be recognized by the ZX81 input circuit (DIN connectors use low levels and expect high impedance inputs, the ZX81 inputs are low impedance).

Re: Artic ZX Galaxians - now with ZONX support (and Chroma81 & UDG)

Strange: when SPACEIHR.P is running on my ZXDeluxe (ZxPand+ZeddyNet), compared to EO the horizontal movement (O/P) is much slower and the fire button (shift) seems to be always activated ...

Re: Artic ZX Galaxians - now with ZONX support (and Chroma81 & UDG)

Maybe that is the same reason, why SPACEIHR.P also crashed on my Zeddy (WRX, ram 8-64K, M1-NOT for code > 32K) ...

The new version of ZXGLX.P crashes on my Zeddy (56K, no ZxPand, no chroma, no ULA, but with Z80 ;) ) when the second screen appears. The old version is running as expected ....

Re: 32k Internal ram with m/c above 32k

I don't think, that there is any usual BASIC program > 16K. I needed to disable m/c above 32K, when I once compiled CHOPPERDROP3000, using MCODER II. The Basic source was < 16K, but during compiler run, the generated code was inserted into program line 2 (or 1?), which increased the size of the prog...

Re: 32k Internal ram with m/c above 32k

if you fit the m1not circuit, you dont need to 'deactivate' it if you have basic over 32768, it 'should' make no difference If a BASIC program is bigger than 16K, the D-file is located above 32K (above the BASIC program). It an M1!-circuit is active, the D-file is executed as code (during dispaly) ...
