Re: Testing emulators using z80test-1.0. Quck results

Independently of the quality of the test tool, it might have some specific dependency on a specific instruction, that if it fails, it might trigger a lot of other fails. What I mean, is a simple fail, might trigger a lot more fails, because the test tool relies on that specific bad instruction, to m...

Re: Testing emulators using z80test-1.0. Quck results

There are some inconsistent results too Running `Z80Full.tap` Gives 002 errors, for example. and I see that instruction INC RR an INC XY (apparently they are different things (could it be second is for iX and iY ?) are returned as OK. But these return as errors, when running `Z80ccf.tap` It's not ru...

Re: Reverse engineering "Stack Light Rifle"

I'm convinced the circuit will be very similar to the one on the Magnum Light Phaser. They are. The interior of the gun is well documented. I just need the interior/pinout of the connector. Yes, I am aware they just work with CRTs. You guys would be surprised to know how many of us still have one o...

Re: Reverse engineering "Stack Light Rifle"

According to Wikipedia the principle is the same of any other gun or light pen from the 80 s. https://en.m.wikipedia.org/wiki/Stack_Light_Rifle The electronics inside the pistol consist of a light detector or photo-diode and a small amplifier and buffer. I'm convinced the circuit will be very simila...

QAOP runs fine (Firefox).

Re: Freezing Basic

Code: Select all

10 FOR i= 1 TO 2 STEP 0
20 PRINT i
30 NEXT i
Dumb loop will keep BASIC ocuppied.
