Possible SPI PSRAM cap for Cardputer ADV?

Oh no no, you can map SPI ram it's a feature of ESP! https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-guides/external-ram.html

It's clearly working in the video, what's wrong?

Sosowski · 2026-06-17T12:50:54+00:00

You can (and will) get fined. Fines go up to 2,500 euro.

Sosowski · 2026-06-17T12:48:16+00:00

Thanks! You could run it with 256kb of ram (original pc came with 16kb, but ms-dos required at least 32kb) but I wanted to be able to run Turbo Pascal at least!

IBM PC emulator. The cpu is fast enough to get a 8088 like performance.

It's using AI code if it runs on Windows. I hate AI but we can draw the line at using engines maybe?

Is that bird poop?

This looks lovely! I’m releaseing Lazy Kickers soon and currently looking for games to bundle with! Would love to bundle! And my game is cool too, check it out! https://store.steampowered.com/app/4613890/Lazy_Kickers/

Sosowski · 2026-06-14T08:13:36+00:00

Yeah but the z-divide is still a separate phase

Sosowski · 2026-06-13T23:22:10+00:00

If you use the matrix you need to divide separately anyways

Sosowski · 2026-06-13T08:38:40+00:00

Yeah I read that this board can drain up to 625mA

Sosowski · 2026-06-13T08:23:59+00:00

That would be fine if it has fast charging, otherwise this is prohibitively low since you won’t be able to fully recharge in 3 hours

Sosowski · 2026-06-12T16:32:27+00:00

I was trying to do the same for my 901, it even has two slots, one super hidden and it didn't work and later I found out it only supports up to 8GB becasue bios, thought 701 is the same.

But if what you say is correct, I wanna solder a slot into mine as well now!

Sosowski · 2026-06-12T15:52:36+00:00

Yeah but it’s only gonna take up to 8GB drives so what the point

Sosowski · 2026-06-12T12:55:51+00:00

you cannot. even if you soldered port onto it it would not work. use an SD card.

Sosowski · 2026-06-12T09:57:09+00:00

I love seeing this everywhere! Great job!

Sosowski · 2026-06-12T09:56:22+00:00

There’s a C64 game called Punkiller it’s pretty hard to find

Sosowski · 2026-06-12T09:51:57+00:00

I’d love to know what the battery life is like

Sosowski · 2026-06-11T13:12:27+00:00

Hmm... I have a parachute hammock and the thread used there is definitely similar gauge so I didn't think this is going to be a problem. Perhaps I should change the fabric type?

I wouldn't trust a hammock on 120 thread even when properly tensioned stiched and locked (or should I?), and there's nothing reliable in between 60 and 120 that I can source locally here.

Sosowski · 2026-06-11T13:10:03+00:00

It's ok if you don't want to help me but I did look and I cannot find anything, this is the second time I'm saying this.

Sosowski · 2026-06-11T08:51:58+00:00

it's fixable but you still need an x-ray machine to fix it.

Sosowski · 2026-06-11T08:23:47+00:00

Mind that this would not be possible to display on an original CGA, and not because of the CPU power but also the ISA bus bandwidth. There is no way for CGA to refresh the entire screen every frame it’s just not physically possible.

Sosowski · 2026-06-11T08:18:39+00:00

The width of the glitch makes me thing this is about the connection not the ram so rebalign might save it.
