Re: WP32 McCake : MT32 compatible waveblaster board

Posted on 2021-07-12, 11:02

I didn't have enough time for testing last weekend but I'm really impressed so far. MT-32 emulation sure sounds nice and I really like how easy it is to change modes with mt32-pi command line utility. Soundfont support is very nice also so this one little internal MIDI-device really does it all. I'm …

I was last of the early birds to get McCake. It arrived yesterday. Fully MT-32 compatible MIDI daughter board is quite unbelievable. And it supports soundfonts as well. I didn't have time to test it yet but I'll try to do so today. It should be an excellent board for any MS-DOS gaming system, Copam …

I must have had back luck then. Slow card have worked but 1993 cards have not. I've tested one CL-GD5422 based card and it did not work but worked on a 386 and 486. The #9 S3 928 I already tested on Copam did not work on my 286. Then there was one Ati 28800-5 based ICL card but again, it did not …

I recommend to avoid line-in on old Sound Blasters. It can reduce the quality a lot. There are alternatives to using external mixer. I like to use Creative Gigaworks T20 and T40 speakers because you can connect two devices to them at the same time. You only have one common volume control but it has …

New RAMDAC is now on its way. Actually I found a whole ISA card based on WD90C30-LR controller. It is very good, actually. And not only that, this card has RAMDAC already on a socket so it makes things a lot easier. What makes the WD90C30 so good? It is fast and has good compatibility but most …

I took a look what the RAMDAC in the DECpc is. It happens to be Sierra semiconductor RAMDAC but too good one, SC15025. It doesn't even support 6-bit mode so I can forget that. I did more testing about possible speed sensitivity of the Bt RAMDAC. Setting CPU to 16 MHz did not help but disabling …

This is from Bt datasheet: "Occasional accesses to the color palette RAM can be made without noticeable disturbance on the display screen; however, operations requiring frequent access to the color palette (such as block fills of the color palette) should take place during the blanking interval." …

I had to put the UMC RAMDAC back last night for testing. I noticed some graphics errors (color dots) with the Bt RAMDAC and I was pretty sure the UMC did not have them. And it didn't. These dots that the Bt displays are usually visible while loading etc and not during gameplay. So these are related …

Those look really nice. Do you happen to have proper color codes for the paint? I'd like to try repainting a case or even monitor someday and I'd like the color to be what was originally used. I got rest of my CF-HDD-drives ready and I turned the CF adapter around so now the cable goes nicely. Here …

Actually it is 1,8" drive but I'm sure it would have been possible to use 2,5" drive and adapter as well. I wanted to make drives like this since it is very hard to access CF cards if they are behind computer. Also cables are usually not long enough to connect HD as master and CF slot as slave if it …
