By the mid-90s in Southern France where I come from, I only had one friend with a PC on which we played Doom, the 3d was making me feel sick to be honest, and MS-DOS was just scary. Microsoft was considered evil and PCs were still quite expensive while being completely unsexy. Macs were super expensive AND boring. Console gaming was expensive too
I had several friends with Amigas and I wanted one so bad. I managed to convince my parents to buy me an Escom 1200HD with Blizzard 1230. This is quite late I realize but the cost/performance ratio was not that important, this is what I wanted. I must have had it for 2 years from 1995 to 1997 before selling it to finance a piano keyboard. During the first lockdown, I had time and money to get a 1200 again and I don't regret it. It's the perfect hobby computer to reconnect with what made you like computers in the first place! Nowdays, the 1200 is upgraded with 060/RTG/WIFI/sampler/midi-MT32/shitloads of ram/Graphic tablet on a second serial port,PCMCIA SCSI: all this with the 1200 still in the original case. The machine is rock stable and fast, it's a pleasure to use it. I don't think the design was bad at all considering everything I do with it 30 years after and how much you can expand it! It's for me one of the best computers ever made, not so disappointing! |

It is incredible that without any upgrade, Paula on Aga can push 56hz and 14 bit audio! Why both blitter and copper can't take advantage of Doublescan as Paula ?

PCMCIA "Memory and IO" mode is for IO (64K address) addons. "Memory only" RAM expansion wasn't ideal use for laptops since can't be made as a semi-permanent system RAM configuration (i.e. hanging on the side has less durability) and was displaced by internal SIMMs and SO-DIMMs. PCMCIA memory-only expansion cards flopped in the PC world. Laptops have added mobility premium that is matching with market demand. A600 is not a laptop and it looks like a toy computer when compared to A500's full-size keyboard. PCMCIA doesn't allow for CPU acceleration addons and is effectively an anti-GVP job. Last edited by hammer; 21 May 2024 at 04:07. |

Potential AGA install base: +570,800 units. 165,000 Akiko C2P capable. This "Amiga 2200" has Akiko C2P on a desktop Amiga computer. $1199, 2 MB 32-bit Fast RAM, 210 MB HDD, 880K FDD. A valid 386DX-16/386DX-20 SVGA competitor with chunky pixels. $1599, 68030 CPU @ 40Mhz / 68882 FPU @ 40Mhz, 4 MB 32-bit Fast RAM, 1.76 MB FDD, 420 MB HDD. It seems the 4MB Fast RAM/68030@ 40 Mhz/Akiko C2P combo is targeting a certain PC game. It can be made cheaper with a lower-capacity HDD (e.g. 120 MB or 150 MB), no FPU, no ISA slots, no Compatibility Slot, no CPU Fast Slot (A4000/A3000 series compatible). Common features for Amiga 2200 1 x 150 pin "Local Bus slot" (Same as trapdoor slot in an A1200) 1 x "Compatibility Slot" (for some sort of 486 bridgeboard) 1 x CPU Fast Slot (A4000/A3000 series compatible) 4 x Inactive 16bit ISA slots. 7 x Other Slots (probably Zorro II or III). 1 x CD32 card with Akiko C2P. Optional SCSI. The "Agent 88" card is attached to the CD32 card's expansion bus. AUD (Australian Dollar) and CDN (Canadian Dollar) are close. The economics of scale is 65,000 units for this batch. Lew's direction is pretty good, but Commodore runs out of time and money. For H2 1993, Amiga 2200-2 configuration and price range are on my list. The added flexibility for A1200 and A4000 CPU acceleration cards is very good. I like "Amiga 2200" to replace my A3000. That A600 debacle needs to be removed from the timeline. AmiTech's CD32-based A2200 is a clone and it's different from the ECS-based "A1000Jr" (A2200). Commodore Canada, Commodore UK, and Commodore Netherlands could have continued trading if the CD32's warehouse wasn't in the Philippines or any country with tight relations with the USA. Ali hired the wrong head of engineering i.e. it should have been Lew Eggebrecht from at least 1989. Last edited by hammer; 21 May 2024 at 09:58. |

But anyhow, I'm not sure how did you make a leap from my "it's possible to enjoy games without hi-quality (or sometimes even any) sound" to "An Amiga without Paula", which really is as far from what I was trying to say as possible. |

Because of the expectancy that was made once you have witnessed such an experience aforementioned. So yeah, for my part, the "pew-pew" games were not enjoyed so much after that. Perhaps it's me but the games I remember had clearly good sound tracks. A least a good intro. Perhaps my memory is biased due to music of cracked intro. |

With 15 kHz screen modes, Paula has up to 28867 effective DMA cycles per second.
With double scan screen modes, Paula has up to 57 kHz (57734). Nothing is free and ECS's color display capability is degraded. Last edited by hammer; 21 May 2024 at 14:25. |

The number of DMA slots per second stays the same, it is still the same old 3.5MHz cycle like in the A1000. So Copper and Blitter can not do more work. But Audio DMA gets called every display line - no matter how long the line is! All video modes above 15kHz do have shorter lines but usually more of them, hence Audio DMA occurs more often Look up "video line frequency" on Wiki or ask your favorite AI. For the DMA slots per line on Amiga view: http://amigadev.elowar.com/read/ADCD.../node02D4.html |

I wouldn't call audio subsystem dependence of screen resolution particular advantage...

Ecs I Know it, but not OCS. It is still fascinating.

in a ideal world Paula would not be part of the trio, but Agnus and Denise would stand alone, and Paula would join DMAC and an (optional) HD controller. |

Is not only about DMA, but buses
