Re: 286 “Turbo” Speeds

Ok, so finally got the boards... The 25MHz one if a really tiny board, using SIMMS and with 20MB of RAM installed (2 are free so could expand if desired). The crystal is a 50MHz one. Now, while the chip is 25, sysinfo 8.0 (from Phil’s dosbench suite) says it’s 24MHz? The only “playing” I have done …

In any case, the ones I can get here are about $35 but for the whole motherboard/cpu/RAM. And another one for $40-$45 but also including floppy controller, floppy, compatible vga and keyboard Nice! I had no idea you could by new XT parts for so cheap. Is that with 640k of RAM or 1mb? Another …

Are you talking about just the cpu for $20? New (NOS) 8088s, 8088-2s both intel and other brands cost like 1,5 USD. https://www.utsource.net/itm/p/439126.html V20s are a bit more expensive - around 11 USD. https://www.utsource.net/itm/p/1869159.html UT Source is just one place where they are …

For a 286, low speed refers to the clock of the original IBM AT, so either 6 MHz or 8 MHz. Everything faster is "turbo", just like it was with the XT (Turbo XT = >4.77 MHz). Now whether it goes down to 6 or 8 MHz depends on the quartz crystal installed on the motherboard. E.g. on a 286-16 you'd …

Vast majority of early clones were 8088 Some were 8086 Faster came later So the ones I see with NEC V20s are rarer? Better/worse/the same? The NEC V20 is a 8088 clone. It is a bit faster than a real 8088, and very compatible. IMO I think real 8088 is a safer bet. You can still buy them on ebay for …

Hi again, Back in the day my first PC was an XT clone. I did not look into these thing back then, and I have no idea what processor that machine had. I am now looking to purchase an XT clone again, and I am wondering: what were the most common CPUs used in XT clones back then? I know the original …
286 “Turbo” Speeds
Posted on 2019-07-31, 00:54
Hi folks! Back in the day, around 1991, I had a 286 “AT” clone. I don’t remember which cpu exactly, but I do remember here in my country they used to advertise these by their speed, and “dual” speed at that. So for example, they would offer you the “AT 12/16” model, the “AT 16/20” model, and the “AT …
Re: Voodoo 3 Standalone or in tandem

So having both a PCI Voodoo 3 (2000) and an AGP Voodoo 3 (3000), besides hoarding/stocking, regardless of whether it makes sense or not for the dual setup, would there be any point in keeping the AGP one, or just keep the PCI one and sell the AGP version?
Re: Voodoo 3 Standalone or in tandem

Not with a TNT as performance is still pretty close but something later it may make sense. I've got a P3 1Ghz with a Ti4600 as the primary and V3 as the secondary. Most Glide games also supported D3d so if you select D3D it'll just show on the primary device. If you select Glide it HAS to go to the …

It makes about zero sense. V3 3000 was faster where it counted, and in that era of windowns software you often had no way of selecting which card to use. Didnt stop Alienware http://i.imgur.com/SU2TG.jpg That was one of my doubts, regarding card selection, although in windows I would assume it …
Voodoo 3 Standalone or in tandem

Hi All, Coming from the Voodoo and Voodoo that *required* a 2D card, and that I was pairing with other 3D cards (Voodoo with Riva 128 / Voodoo 2 with TNT), I pondered doing the same with the Voodoo 3. With the first card I got it wasn’t optimal since it was a Voodoo 3 3000 but AGP, and so I couldn’t …
Re: SC-55 MKII or Regular?
Posted on 2019-03-21, 18:57
well, if your favourite game of all time relies on capital tone fallback, then yeah it matters which one you get... otherwise so few games require capital tone fallback it does not matter and something like an SC88 with more polyphony is better :P and since you cant tell unless the supplier shows …

Walterg74: As for the link you quoted, see this comment by Cloudschatze: "The v2.00 SC-55s do support capital tone fallback. There is a slight difference in drum set Program Change behavior however, affecting the improperly-programmed sequences of at least two known game titles." That comment …
Re: SC-55 MKII or Regular?

The important feature in my opinion is the extra 4 note polyphony of the mkII, which yields better results in later GM games such as Gabriel Knight, or Quest for Glory IV. And IIRC, the DAC might be 18-bit vs 16-bit. But it's not life or death stuff. https://www.vogons.org/viewtopic.php?t=56988&p= …

Hi folks, reading a bit about the SC-55 series, and I’m a bit confused... On one hand, I read that the best one you can get is the MKII, but on the other I also saw the discussion of ROM versions, and it’s also said that an older version (1.20/1.21) was the best one because it lacks no features, and …

Lots of replies, thanks. I am aware of the lmits of different platforms, ut not really looking to overcome them unless there’s a reason. To illustrate, why bother with an inmense hdd for a 386? On such a machine I would probably play floppy based games and how many really were either installable or …

Hi all, building a few machines from different eras (386/486/P1-4) and considering HDD sizes for each... Considering the games that are played on each platform/era, and without having a “kitchen sink” approach, what would you say is an adequate size of HDD for each one..? What if I didn’t want to …
