These guys were also actors on the CPU market at that time : https://en.m.wikipedia.org/wiki/Cyrix

I just wanted to know why peanut butter tastes better on toast than just bread, also crunchy or smooth, which do you think Carmack enjoys the most?

PCs were hella expensive.

Why, though? You're just posting the same things as in the A1200 thread. It makes no sense.

It's a very strange phenomenon

Yeah, HDD drives and SVGA monitors were totally overrated


Aaaarggghh, we're doing it again. The virus has escaped the containment zone. Mod action required.

Didn't need either of those to play Turrican

He doesn't care, as long as it's on pizza. The guy pretty much only ate pizza for the entire duration of his stint at Id.

Plus extra 3mb ram for Doom and don’t forget VAT = £725+£109VAT = £834

Tbh that is pretty cheap compared to the major high street retailer prices. But we all know if you wanted to play Doom in a decent window and speed a 486 was really needed. And when buying a PC buying the lowest common dominator is never a good thing as they get outdated so quickly. Our first PC in 1997 (200mhz) struggled even with a 3dfx card chucked in a year later was not willing to play games on high settings.

Has this been confirmed that he had peanut butter on pizza? That would confirm the mathematical brain powers in the peanuts, and debunk the rumours that peanut butter is bad for programmers.

Apparently he ate the same pizza, day in, day out for years, from some guy that charged him unchanging prices due to his loyalty.

I don't know about the peanut butter side but I find I can work on stuff more intensively when adequately peanutted up.

The pizza is/was a decoy. John Carmack feeds on cosmic particles.

I still think that the SNES Doom assets would allow for a more playable experience on weaker Amigas with 68020/68030 CPUs.

Though, I'm pretty sure that there have been all kinds of mods to make Doom more playable on a 386 machines, but they have been lost to time.

The author of the mod for Doom II -> SNES called SunLit replied to my Tweet. He doesn't know how to go back the other way. The original author of SNES DOOM wrote Amiga tools to go from the Doom Engine map format to the Reality Engine Map format but obviously not the other way around.

Sunlit speculated that textures were reduced and transparencies removed but nothing about modifications to the maps.

There is no floor and ceiling textures, resolution is 320 x 100??, screen is not full screen.

Is it true that the height differences are minimized so that they always fit within the standard screen height? Nothing is higher than the top of the screen?

[alexh]

You know more than me or this guy. Post to the original author on twitter? Read the source code? Report back here ;-)

true, but the game is very enjoyable

Apollo/Blizzard 1220/4 was about £175 in 94/95 or something and Gloom is very playable on that spec.

The Blizzard 1220/4 (which is a very capable turbo board, beating the A3000 in performance) wasn’t available when Carmack stated that the Amiga couldn’t run Doom at a sufferable frame rate, and Gloom is not quite Doom, most definitely not at a definition that Carmack would tolerate.

Apple’s response to this was to release a cheap machine with a 25 MHz 68LC040 and chunky pixels. Commodore’s response was to file for bankruptcy.

If Commodore had been in better financial health and had released the A1200 a bit earlier (eg. late 1991), by the time Doom was released it would have been well established and just might have convinced Carmack that a port was viable.

That’s his entire point. He was referring to real-life Amigas, not the minuscule installed base of A4000 users (if we ignore the fact that Doom wouldn’t run very well even on an A4000 until after years of dogged optimisation).

I might have to frame that quote.

I presume you are talking about the Mac Performa 475/LC475/Quadra 605. It was released in October 1993, 2 months before Doom. And they had other 040 Macs well before that, so your attempt at wit falls flat. The LC475 wasn't a response to Doom at all.

Here's a video of Doom running in low detail mode on a Quadra 700 (full 68040 @25MHz). Frame rate doesn't look great, around 8-9 fps? (my A1200 with 50MHz 030 gets ~14 fps with the same settings).

I think that poor performance would have just confirmed Carmack's opinion that a 25MHz 68040 wasn't fast enough for Doom.

That’s his entire point. He was referring to real-life Amigas, not the minuscule installed base of A4000 users.

And I totally agree with that conclusion.

Carmack would need hundreds of thousands of potential customers to justify porting Doom to the Amiga. The chances of Commodore selling that many 040 based Amigas was nil, not least because if you had that kind of money you would simply buy a PC.
