Thx scali.

What is you suggestion of getting the effects run separately/standalone. The files seem to indicate that (but it worked for none of my incompatible machines) So what about the lake scene? Do you think it's possible to run that on "not 100%" compatible hardware in the future?
The lake scene is arguably the most demanding part in terms of compatibility, and as such the least likely to work on anything that is not 100% cycle-accurate.
There is also no room to make it more compatible with other hardware.

OK thx scali...I already suggested that.
that was the water scene I remembered from ChamnbersOfShaolin on A500.
Your Lake-Effect is so much better than this...congrats!

...I remembered that I own this old Sharp-PC4600 Laptop
...after searching for hours I found it and gave it a try...

Let me know what you think.

Nice, better than expected! Loses sync a lot on the external monitor, but something tells me a lot of it is just the monitor being picky, not necessarily CGA compatibility issues. For example the Marble Madness part appears to work fine, while the tall multi-screen image (~5:22) doesn't. Although as far as the monitor is concerned the only real difference is the overscan color...

The Sharp PC-4600 appears to have an 80188 CPU, which is not cycle-exact to an 8088, it's slightly faster at the same clock speed.
That is likely going to throw off some effects.

Or well, it says '80188 compatible', so it could also be a NEC V20.
Either way, not an 8088.

I will not rip-off my A2000 with A2286 VGA (ET4000K), so I will order another A2000 KS 1.3 motherboard. I still have three A2088XT and beside the CGA Emulation on this, it's possible to put in a real CGA card.


This does not seem like the correct course of action to run a cga-register-level, 8088-cycle-counted demo.

I know Jim, but I have to test this because actually there is no way of getting the real thing for an acceptable price. Just ordered that CGA card.

This is the Adapter I am using on my EuroPC, Tandy1000 and on that Sharp PC4600 to convert MDA/CGA/EGA to VGA on a suitable TFT like my Nec 71vm. I already tested this Adapter against my real 1084S and there was no difference on the EuroPC, but I did not have tested this with the sharp yet. Now I am on vacation for 10 days. Best regards Doc.

That's not an IBM CGA card.

I have a 13” 2021 MacBook Pro with an M1 processor. Will that work?

instead of looking for old compatible hardware I would give FPGA a try

from the prod thread:

Impressive demo, congratulations. I've been able to test it on the PCXT core I'm running for the MiSTer platform and except for some glitches it works pretty well!


this seems very impressive when you consider that many real PCs fail ...
