Re: What am I doing with a 286?

Posted on 2017-08-30, 01:10

Just one more thing! I've just seen two 128KiB upgrade cards at eBay, ending today (16:18 UTC, 17:51 UTC). They claim to be for the PC/AT 5170. Maybe they also work for clones ? The original AT was running ISA at 6MHz, after all. Anyway, here's the link: http://www.ebay.de/itm/152671099914 and …

You're right. Because of this, I once built myself an Composite to S-Video adapter for my 1702. It was essentially the one from Wikipedia. https://en.wikipedia.org/wiki/S-Video#use I'm afraid it wasn't perfect, though. The old Chroma/Luma ports had a different impedance than modern S-Video. Edit: …

Cool! You've got my best wishes. Hope you get that memory card soon, too. ^^ (though it is a sweet little monitor) Yup, I had the almost same model as a kid (PAL). ^_^ Long, long ago my dad gave it to me and so it became my Nintendo monitor (NES+SNES). It did a good job for composite video, maybe …

Thanks for all the replies so far (please go on)! ^_^ In my opinion, an era doesn't end just because there's a roll-over from one decade into another. The tranistion is rather smooth, I think. Sorry, I'm not so good in coining sentences. Let me say it this way: The 80s didn't stop in 01.01.90, but …

Next step is find a VGA card and memory card. I'm sick of composite quality CGA already That's understandable. :) If the current EGA (?) graphics card can't do proper Composite CGA then there's little practial reason to keep that card installed, since some early VGA cards have emulation modes for …

Oh, there's something I forgot to mention! You can actually use a Hercules card to get 64KiB of UMBs. Since you're running a CGA system, it would perhaps not conflict with your video memory (if Hercules is set to half-mode). Together with the extra memory in the HMA (High Memory Area), you could …

I would have assumed I would get 640k/384k. I may search for a memory card that has documentation, etc. You're right - That's how it is supposed to be. I am not sure as to why your machine behaves so differently. On the bright side, there were a lot of no-name 128KiB upgrade cards which were meant …

Re: SB16, no MIDI out through gameport

I would prefer a real OPL3 but I'll settle on the AWE64 for now, it's so quiet :) Awesome, glad it works now! :D I hope you didn't mind that I'm not so much of an PnP fan. I didn't mean to say that all SB16PnPs/AWEs are bad cards per se. While it's true that I prefer classic SB models (non-PnP), I …

In all the sooundcards that I have checked (quite a few): the waveblaster midi pin is hardwired to the DB15 port midi pin. Thanks for verifying that, I thought the same! ^^ My CT1740 is currently boxed up, but the CT2230 here has several resistors located near the DB15. On his card, maybe some of …

Jo22, thanks for your reply! I have a CT1740 Sound Blaster 16. There is no MPUEN jumper on that card, only a port select (300h or 330h, currently on 330h). I have verified the cabling multiple times... I will try again with the AWE64 to confirm it is working. You're welcome! I look forward to …

Nevermind the memory issue... changing the Base/Extended to 512/512 fixed it! Whew! Glad it worked! :D These XT RAM cards (or UMB cards - both are essentially the same) can be quite finical at times. I own one of these, too, and without the manual I'd be totally lost! :sweatdrop: By the way, If you …

Hello olivil! It works via the waveblaster header, but not the DB15 port ? Strange. Please double check the cable. Try switching both ends of the cable, if necessary. Sometimes a labeling like "MIDI OUT" means "TO MIDI OUT", which can be quite confusing at times. :confused: Also make sure the " …

Thanks for sharing ! :) Also thank you for the background story, which you wrote so feelingly. ^^ This PC totally reminds me of the transition between old and new millennia. Back in late 20th century, there was this feeling of a new hope and euphoria (..) and more natural, colourful, more rounded …
