Anders: did you get the Vic to recognize the hdd? I recently got it working with a pre-partitioned cf-card.

Well done!

Thank you, problem solved!

Hi guys, Quick question: I just bought a Victor V386MX (the 16 MHz 386), but it seems to be password locked. Anyone know where the jumper for password reset is? (or default password)

Yes, the computer is based on Tulip parts, see post #3 above.

There we go!! https://www.dreamcast.nu/wp-content/uploads/2019/11/Tulip-TC40-bootup.jpg https://www.dreamcast.nu/wp-content/uploads/2019/11/Viatel.jpg The form factor of this computer is quite interesting. No 5.25 slot. It was assembled in Sweden and came with a huge modem card. According to their …

Phoenix bios, so 3-1-4-1 means "Test 512K base address lines". Hm.

Pinouts corresponded to AT standard. Now I have a more delicate problem: Error beep code 3-1-4-1.. Computer powers on, but gives no video 😒

Thank you, so I just check continuity between the specified pins on the ISA slot and power connector? It seems like "Blue" on the Tulip PSU corresponds to "Yellow" on a regular AT, since the 12V pin on the Molex connectors are Blue. That is a good sign, since they are flipped on the P1/P8 connector …

Sorry, I meant Tulip TC40. Below is images of the motherboard, and the PSU. The motherboard has an additional power connector, but I could not see any such cable on the original PSU. https://www.dreamcast.nu/wp-content/uploads/2019/11/mobo1.jpg https://www.dreamcast.nu/wp-content/uploads/2019/11/ …

I just bought a 486 with a Tulip PC40 motherboard and a (dead) Tulip Power Supply. When I bought a new AT power supply, it seems like the color of the cables does not match, as shown in image below. https://www.dreamcast.nu/wp-content/uploads/2019/11/AT.jpg In the top part of the image is the color …

Solved: I hooked up a cheap Chinese 5V audio amplifier between pins and speaker. I have no idea what caused the fault though. Tried to replace a few caps on the motherboard, without any difference.

I ran into some troubles on my Compaq Presario CDS 520 (486) the other day. Basically, I was messing around with connecting a small amplifier board to the integrated speakers. The right speaker also serves as PC speaker. Now, after the installation I noticed that the sound of the PC speaker is …

I have a question about the integrated speakers in the Compaq Presario CDS520: I plan to build a little mod and utilize them with a sound blaster sound card. Are these speakers active, or do they need a form of amplifier if connected to an external sound source such as an extra sound card in the …

Sorry for reviving this old thread, but I just bought a Compaq Presario CDS 520 and have the exact same issue with sound volume. First, I set all essvol to "2". So far I tried three games: Pinball Fantasies. When running this game in soundblaster pro mode, the music is insanely loud, and when I …
