Ah, I guess simple solution is SCSI2SD by Michael McMaster: https://www.codesrc.com/mediawiki/index.php?title=SCSI2SD and use SD card instead of SSD.
SAS SCSI for retro computing
Posted on 2021-06-29, 15:06
Hi, can you get some SAS SCSI cable with SATA connectors and use it on SOME controller for ISA VLB or PCI? I read that SAS SCSI use SCSI command set, but I don't know if it is compatible with old parallel SCSI or if there is some adapter or some retro controller with different connector. The goal is …

Regarding the 2nd card, the Waveshare addon is not made anymore: http://www.flxd.de/isa-ws-sl811/ ...but I guess you can find some other USB host to serial adapter. I don't care about period correct. 1996-1987 is only 9 years. Everyone had some computer for around 10 years and upgrade the parts …

Hi, I have same issue. Bought Hippo VL+ rev 2.2 and both Mr.BIOS and the second one (keyboard controller) are missing. I need to buy some parts and flash them myself. Any chance of finding rom for keyboard controller (the one next to it) as well?
Re: Does anyone got working Chaos Engine, the CD version with Roland music (MT-32 or SC-55) ?
Posted on 2021-06-16, 23:58
Ok, thank you very much for the hints and help! I already tried MUNT and various configuration. I forgot I'm a music producer and have full blown expensive studio soundcard with midi here...just got attached to gameport somehow, hehe. I run SC-55 in MT-32 mode, which is not 100% MT-32. The music in …

Perfect, thank you! I bought sealed CD US version on E-Bay. Perhaps I need the patch for SB :-) !! Thanks for the tip with DosBox. I tried DosBox-X (tried also DosBox SVN Daum) with this opengl yes....I'm playing on Samsung QLED with Radeon, which can do VRR (variable refresh rate), so mostly I have …
Re: Desert strike roland canvas or mt32
Posted on 2021-06-15, 22:26
So communication with midi in this, lets say Amiga PC port, might be caused by fast CPU? Because some even older games work and play MT-32 on this machine, but they are not Amiga ports. And I get this same issue with Chaos Engine CD version, which says on cover: for 386, 486, Pentium. I tried some …
Does anyone got working Chaos Engine, the CD version with Roland music (MT-32 or SC-55) ?
Posted on 2021-06-14, 15:50
Does anyone play Chaos Engine? I got this CD version, which got some extra video footage. But I can tell you, making 610kb of conventional memory including sound card driver and cd-rom driver was pain in the ass. Also this CD version runs great on Pentium. The floppy version is playable only on 386 …

Yes, if I don't connect Roland, it will switch to NO CARD just as you say. But if Roland is connected, it will hang. But it happens only on my Pentium machines and Sound Blaster. Perhaps time for SoftMPU? I tried it on 386DX and everything works out of the box! LOL Just a note: standard midi address …

Sound card is Sound Blaster Awe 32 PnP. It does not or should not need SoftMpu.
Desert strike roland canvas or mt32

Hi, mpu address is 330h. Doom is working with roland sc-55. Kyrandia is working with mt32 emulation mode. Desert strike and jungle strike are working with sound blaster. But everytime in game menu I choose Roland sound canvas or Rolant mt32, it will freeze and PC needs hard reset. Manual does not …

Yes, just check the continuity of the fuse - put your multimeter into continuity mode and (with the computer off!) put one probe to one side of the fuse and the other probe to the other end. It will vary on your model, but on my (ancient) Fluke 75: IMG20210603110448.jpg My guess is that there is …

megatron-uk wrote on 2021-06-03, 09:08: Keyboard error and faulty fuse: Yes, that might look like it. Either the fuse or Amikey controller. But how to measure anything on the fuse? Fuse is only for current, you cannot measure any voltage or resistance on fuse, right?
Re: 486 no keyboard found, only PC speaker beep

Check continuity on the 125v rated green fuse at the top left; it protects the keyboard/keyboard from over-voltage and shorts. I had similar issues on my identical PVI SP3 ("no keyboard detected", "keyboard failure" - a quick flash of lights on the Kb itself, and then nothing) and it turned out the …

But I should not connect the Teensy to USB 5V. He clarified it is not needed. Which I did not know and the RGB keyboard won't even run without it. So I guess if there is some voltage from PC DIN (I guess 3.3V). Then there is some logic converter 3.3V to 5V. Then there is Teensy USB with additional …

Maybe check if this applies to your motherboard, maybe you can avoid pulling out the mobo. https://diagramweb.net/img/ps2-keyboard-to-5-pin-din-wiring-diagram-12.gif Funny that it's in Czech language...which is where I am right now.

As Nexxen said, a picture of the motherboard (or the make and model would be helpful). If no keyboard is connected does the motherboard boot but halt with KB error like it should or does it do something else ? Yes, if keyboard not connected, it goes through POST and report KB error. The board is …

Ok, I got response from the maker of this adapter: "To protect the motherboard, a logic level converter (the smallest board) is installed on the adapter board." "Furthermore, each motherboard has a fuse on the +5 volt line, I recommend checking this fuse. Your motherboard is kept safe by these two …
