It would bottleneck performance on the Pentium due to the slower ISA bus.

Even on 486 machines, 32 bit VLB and PCI slots were introduced to provide greater bandwidth and performance for expansion cards.

Thanks for the explanation. That makes sense!
I thought It could be a replacement of my aging Trio64 PCI card.
But I had not in mind that ISA is much slower than PCI.
I will remain with my Trio64 card in my pure DOS build.

This looks very exciting, It reminds me of VideoLogic’s Apocalypse 5D Sonic! Which leads me to ask is there a plan tio supply a gameport adaptor cable with it? IIRC the said VideoLogic one I think came with an adaptor cable.

there is no plan to include a gameport bracket, this is designed to work with the common motherboard ones you can find (hopefully?) on ebay/ali/etc
the only adapter cable this will come with will be the midi port one

since the design is validated and the only real change needed now is the option for banked/linear vram access for GD5434 we have opened the preorders for the card
we aim for a xmas-time release , all info is in the card's page 😀

Hi Keropi, I’ve sent the pre-order form... do I need to wait to hear from you before paying the 50%?

One more question: will you also be releasing the "standard" video card based on the GD5434?

Thank’s for your time 🤗
