Sinclair ZX80 core?

[DrOG]

Hi all!

I found a ZX80.rbf core browsing Gehstock's github repository:

https://github.com/Gehstock/Mist_Cores/ ... air%20ZX80

Tried it on my MiST using differet monitors, but the result was no picture in every setup (15/31kHz).

Is it a work-in-progress core, or am I missing something?

Unfortunately there's no readme/howto documentation, perhaps the core needs an external .rom file?

Attached my results from the TV's framebuffer:

No Problems here (Rom included no extra Files needed)

Hmmm...

Similar graphic glitches as in case of ZX01/ZX81 core (see red circles on attachments). But this one works with Belinea, the ZX80 doesn't.

Will try it on other monitors also (tested Samsung LE40B650, BenQ BL912 and Belinea CRT so far, didn't work with them. Will try LG DM2352 and Philips Hotel TV also).

By the way: is this core 15kHz compatible?

[Gehstock]

it should, will check Core the next Days

Thanks in advance!

Tried all my monitors without success, will download the core again later (I am not at home now).

Redownloaded the core, it's only 241,9 kB, 15 kB smaller than the ZX81/ZX01 core.

Maybe it's trunctated?

This is normal, ZX80 has only a 4kb rom (ZX81 8kb).
New Version could take some time (just refresh the Dev Computer)
