Sinclair ZX80 / ZX81 / Z88 Forums

That's why the sponzy was made - to compare the interpreters on same hw.
The Fast mode is ideal for this purpose, no display/keyboard handling.

Hi all, I have always been interested in what are the tests that the magazines just referred to as BMn. Finally, in July I found an exact description of them. I was curious about the performance of SPONZY , so i quickly tried them out using the EO. Used ROMs for the test:ZX Spectrum, ZX81(in fast/sl...

Hi, Here is it! :D It was simple - were stopped after the load, pressing the BREAK key. But now it starts not automatically :( - just type "RUN". Enjoy Zsolt PS: If you have not a ZXPAND, i recommend to use (my project of course) the Hibrid Loader ;) http://www.sinclairzxworld.com/viewtopic.php?f=6&...

The tape loader part of SPONZY did not work with a real hardware - as it was also reported by Siggi. So I decided to study our favorite from this perspective. The by-product of this work is in the attachment. The basics of the hardware: Due to the hardware solution of Zeddy's EAR-port, it is easier ...

Hallo Siggi, Thank you for all help. If my additional HW will be ready finally, I will continue the test with following steps: step 1: Load a testprogram (a wav created in EO/SPONZY) into ZX81/SPONZY; step 2: Load same testprogram (a wav created with ZX81/SPONZY) into EO/SPONZY; It may come out whic...

Hi Siggi, I hope, that it is not corrupted.... No, that was OK, but buggy - the corrected version is in attachment. I was thinking a lot about "white screen during load" in real Zeddy. Possibly it causes the different construction of the tape interface: SP_ZY_TAPE.jpg What's happen if you (without t...

Szia Siggi! (Hi) were the commands correct? Yes, the syntax of these commands is same in Speccy too. I tried your steps in EO - SAVE "test" then NEW and LOAD "test" - there was no problem, 'Zeddy' switched to FAST mode. But the screen remains white (no black stripes) and nothing is loaded. :( I don'...

Dear Siggi,

Sziasztok! (HI ALL,) SP81 - there was more (mostly timing) problem: It seems that I wrote bad things only about sp81, but it has a really good part, which is (with some modification) implemented in SPONZY too: the NMI-stack. To calculate the addresses in the Speccy's nonlinear H-File is a time-consu...

Szia Siggi! (Hi Siggi,) So my first question is; where is the D-file located in your rom? The D-FILE is located at the end of printer buffer - this is in the 16K-32K region, in front of system variables. If printer is in use, Zeddy is in FAST mode. The printing session ends with clear buffer, so we ...
