Re: Amikey-2 pinout

It's OTP ROM. OTP for One Time Programmable and ROM for Read Only Memory. EPROM is Erasable Programmable ROM. OTP EPROM would be a contradiction. EPROM are UV erasable, EEPROM are electrically erasable. While the term is confusing, there are EPROM dies packaged in a cheap plastic case without a …

Re: How to get a secondary monochrome monitor working in DOS and how to connect it to a modern display?

The BIOS is also split into two chips, which would make any kind of flashing of alternative firmware very difficult. The chips that it comes with are also OTP. I don't know if there is a compatible EEPROM. Those chips are likely standard 16KB (128KBit) OTP EPROMs or 128KBit mask ROMs. The pinout is …

Re: Trouble installing Matrox G450 PCI on Win98(SE)

The G450 seems to be a PCIe internally. You can see the large PLX bridge chip near the PCI edge connector and the installation of a PCI-to-PCI bridge driver when it's first detected. This is most likely the cause of the Bus Mastering issue. It's not PCIe, you skipped a generation. The G450 is AGP …

Re: Ct3670 eye candy

But the onboard sound ROM is definitely not as good sounding as my Ra-30. That's not surprising at all. The RA-30 is claimed to have 1MB of compressed audio samples . The AWE32 ROM has 512KB of 16-bit PCM uncompressed samples. Assuming a 3:1 compression ratio, the RA-30 as six times as much sample …

Re: Ct3670 eye candy

Clear as mud! 🤔 I was just hoping it would be like unlocking some old gpus and give increased capabilities. Well, it actually is a good comparison: Just as GPU unlocks just permits the driver to things it wouldn't do without the unlock, without physically changing what the hardware can do, this is …
