Just listened to interesting podcast on Hackaday with Eben Upton on all things Pi where he is asked what was his favourite programming language (@ 1hr 2min 26secs). Close contest between 6502 and 68000

So it turns out the NEO6502 couldn't be easier to use :-) It comes with with something already installed ( ProDOS , a filer/launcher front end to Apple II emulation, complete with BASIC and a dozen games). Just needed to hook up HDMI monitor, USB-A keyboard, power to USB-C and the system is up and ...

I keep seeing those advertised - I've got a couple of the lilygo boards already - and they are wonderful little things - but I am struggling to justify why I might need this one ;-)

Ha!, just received mine today from PiHut, along with a AgonLight2 with case and protoboard. No case yet available for Neo6502 unless you 3D print one.

What does that do?

Disables the interface interrupt (IPC activity). Value gets copied to ZX8302 interrupt mask register. QDOS never used it but Minerva introduced it to respond to IPC (Hermes). But it causes slow down on non-Gold systems (FLP activity, POKE!!53,128 restores performance). Don't ...

Try POKE!!53,128

I bought this interface from Dennis Briggs in about 1988 at a QL show. He mentioned his stock of MP interfaces had been updated with the official upgrade from QJump. I also have a copy of the v1.23 ROM (8K), don't know the status...

Miracle WIN driver sets up poll routine to check if booted then reverts device name from MDV to WIN.

So no WIN_USE WIN required :D haven't looked but I guess Tebby FLP drivers do same.

Isn't it because prog_end-start can be resolved immediately as an absolute number. But 16384-prog_end can't because prog_end position can't be resolved until linking/assembly? (16384 seen as fixed address, thus dcb.w size can't be resolved). QMAC manual page 29 Relocation factors: +1-1 (=0 absolute ...
