Sinclair ZX80 / ZX81 / Z88 Forums

My VLA81 arrived safely to Sweden today. I am VERY happy to report I did not get slammed with the usual customs and VAT. I was a bit worried about that since I thought it was delivered from Germany when I ordered...
Will try to get time to test it this weekend and report back.

I believe he's on vacation in the USA, not very active at all electronically.

Working hard at the code I now have 4:3 and 16:9 modes of both the encoder and player. It seems possible to do 30fps in widescreen, so all the people in NTSC-land can have some high frame rate fun

An update to usage in EightyOne:
I used EightyOne 1.12, and you need the correct settings: 32k RAM, CHR$16, no hires, ZXpand+, PAL. Enabling hires (WRX) will muck up the display, even though it should not. And again: it works in slower frame rate, but the images DO look perfectly fine.

I wonder how this would compare to the Dragon's Lair encoder.... I have tested some Dragons Lair material I found online, which was rather crappy to begin with, but this encoder creates OK-ish result. I suspect Jim Bagley has done A LOT of good pre-processing, yielding a very nice result. With the ...

I made a promise when I released the Bad Apple video player that I would enhance it. Since then I've been working hard on upgrading the encoder, both quality- and speed-wise. This morning I made a break-through regarding the quality, so I wanted to show you! Here is a first preview, a full length re...

My small opinions: - Keep the "colour" modes greyscale to fall in line with the ZX81 spirit. A ZX81 with 2-bit greyscale would look lovely, just look at the GameBoy. Easy to use a composite video out with the new modes as well as the VGA in parallell. - It is VERY good to use the 8-16k area, so the ...

The PCB is surprisingly good quality. MUCH better than Sinclair

Naked PCBs would be very fine, and useful if someone wants to take his chance to copy it. Just make sure they are good quality scans, these will be very valuable. I guess you have seen Searle's NMI generator page? I do not think your clone includes an nmi generator at all, the NMI requires 6 more c...

Neazoi: hm, you are probably right. I first imagined that it really WAS a true ZX80/81, but they probably mean it is possible to switch ROM from 4k to 8k. So silly and dishonest to claim ZX81-compatibility :) Oh well, then I really MUST build an NMI-solution for the Minstrel I already have. Might se...
