Hi,
Some MGP/MDA cards have Character Generator ROM (UM2301, Sis23C01, etc.) as optional chip. However, some MGP/MDA cards have Character Generator ROM soldered. Is it important to have the Character Generator ROM in the card? What is the benefit to have this chip?

Well as i heard, ROM chips on Hercules cards are for local fonts. So if you missing ROM chip on your card, then you cant use national characters different from english. Ofc you have to there right fonts burned in chip. Often you can see stickers on cards like PL (Polish) or Cz (Czech). VGA cards can load fonts into memory from harddrive, but Hercules cant. So if your card missing ROM chip, it would work, but only with english fonts.

I have a MGP/MDA card with the corrupted ROM. In my case without the ROM, my video card does not run ok. After I soldered a ROM - UM2300 because I dont have a UM2301 chip or Sis23C01 but it show doble characters. Perhaps that chip (UM2300) is not compatible. I have looked for the Sis23c01 datasheet, UM2301 and variants of them but there are not info on Internet. Do you have the datasheet?

Dear Vlask!

Did you find any further information about your card?
Is this an hercules only card?
The J1, J2, J3 jumpers can switch modes?
I just bought a card that looks like as yours.
