FAQ: Read first! Your question is probably answered here... "Why didn't you put machine X, Y and Z?" Because if I decided to put the Amiga 3000 and 4000, then I'd also need to put some Compaq Deskpro, a few more Tandy, and so on, and it would have been 150 and not 80 machines in total, and 1.5 hours long instead of 40 minutes which is already borderline (and it would have been even longer if there wasn't a real effort to speak quickly). "This is not the only available resolution" Yes. Same reason: if I was to put (and I tried) every possible resolutions, it would have been illegible as a result. So the answer is to indicate the most commonly used res, and not max res or every possible res. "This is not the right color palette" No. The "color" value is not about palette but on-screen colors. "Then why not add color palette?" Same reasons as above. In general the aim was to display only the most concise information. I tried different versions, and it doesn't look good when there's a lot of text. Thanks for watching and for your constructive comments! This video will get better with each iteration, that's the goal :)

[@RetroDream]

[@lawrencedoliveiro9104]

I’d be curious to see something of the Mindset and Sirius/Victor machines. These were attempts to go beyond the IBM PC standard with extra capabilities, but it seems the market just wanted “compatible”, and nothing more, so they flopped.

The BUS speed as different from the CPU internal speed. The ZX81 may have had a Z80 but the machine didn't run at that speed. Brilliant nostalgia trip. Thanks.

[@RetroDream]

Thanks, very appreciated! You are correct, this synthesis only focuses on the CPU.

[@lawrencedoliveiro9104]

18:58 That _Flight Simulator_ screen on the Tandy is apt, because that standard for demonstrating “IBM compatibility” was the ability to run that app. That’s why I think the proper term should have been “Microsoft compatibility”.

[@vladtru9670]

Great job and impressive visualization of the computer timeline of that era. There is a small clarification about the BK-0010 - this is a real 16-bit home computer on a 16-bit K1801VM1 processor (PDP-11 compatible). The number of devices sold according to official data (all BK models - 0010, 0010-01, 0011, 0011M, etc.) is about 160 thousand; BK was produced from 1984 to 1993. Among the interesting and unusual Soviet PCs, one can also mention Electronica MS0511 (UKNC) - this is the most popular model of Soviet PCs, it was usually used as a school computer, it had two 16-bit K1801VM2 processors with frequencies of 8 MHz and 6.25 MHz (their speed in total is approximately 4 times higher than that of the BK-0010/0011M processor), 640x288 graphics with 16 colors (for each line of the screen the resolution was setting (80, 160, 320 or 640 pixels), palette and address in RAM (that is, smooth vertical scrolling was supported and stepped horizontal), RAM 192 KB (of which video memory is up to 96 KB), ROM 32 KB, single-voice sound (hardware and software), cost in the minimum configuration from 1000 to 1600 rubles (about 2 times more expensive than BK-0010 and almost identical to BK-0011M), was mass-produced from approximately November 1987 to 1993, more than 300 thousand units were produced. Another relatively widespread home PC in the USSR, close in distribution to the BK-0010 family, is the Vector-06C. It is on a regular 8-bit processor KR580VM80A (analogous to Intel 8080A) with a frequency of 3 MHz, RAM 64 KB (of which video memory is from 8 to 32 KB), ROM 0.5-2 KB (bootloader only, without BASIC), it has an excellent graphics and good sound - resolution 512x256 (2 or 4 colors) and 256x256 (2, 4, 8 or 16 colors), 256 color palette, hardware 3-voice sound, hardware vertical scrolling, video memory of 4 bitplanes, hardware overlay possible foreground to background, multiple frame buffers. Supported CP/M. Vector-06C produced from the end of 1987 to 1993. Cost 750 rubles (slightly more expensive than BK-0010-01). The exact sales volume is unknown, an approximate estimate is 100-120 thousand.

[@RetroDream]

Many thanks for your very informative precisions! I didn't know about the UKNC and the Vector but they could be part of the future update in this Timeline. Very decent sales figures, they seem quite popular indeed. Need to investigate :)

[@markenetube]

The Spectrum + was a normal spectrum stuck on an upgraded keyboard. They sold the keyboard as a it so you could DIY. I did, and also soldered on a joystick port. Those were the days.

[@oleJackBurton]

When I was first learning my PC hardware skills I built an 8086, 8080, 286 and 386 from spare parts a teacher gave me and a teach-yourself computers book. It was a tour of legends over the summer between junior and senior years in high school.

[@RemnantCult]

Some days I wish I was a young girl in the those days hanging around computer stores, trading floppies and being amazing at the newest releases. Those were the golden age of personal computing, and while I'm thankful to live in a time where I can study all of these machines and emulate them, I wouldn't mind being able to experience it in some way.

[@RetroDream]

Nostalgia...

[@gklinger]

Had you considered buying some vintage computers? Emulation is a great but it isn't a substitute for the real thing.

[@RetroDream]

Are you kidding me? :) This channel is almost exclusively about the "real thing", each and every video is telling you that emulators are OK but there's no substitute for actual vintage

[@trance_trousers]

I was there (born in 1966) and witnessed it all, it was an amazing time to be alive!

[@lovemadeinjapan]

What I like about the now, is that you can pick your options with the information and tools from now. Which makes me do different choices than our parents back in the day. A C64 for example is not a machine I would go after, as it has pretty abysmal basic and keyboard, and horrible video output, so you are having hard times using the real machine. I do have one as it is a magnet for parents on our school tours though. Back then the C64 was the best ticket to cheap game copying on a twin cassette deck, but today you get a PC Engine Mini and the gaming is covered with much more detail, nicer sound and all the colours. No I like machines for aesthetics of the original hardware, good to use BASIC, low maintanance to keep the hardware running (and its storage!), and good mods and expansion, preferably as non-destructive expansion cards inside the machine, so you can for example run a BBS server on it. Some nice machines in 2024 are the Spectrum+, the Amstrad CPC 464, the Philips P2000T, the Epson HX-20, Atari ST, Mac SE/30.

[@lambdas]

In The Netherlands there was the Philips P200t personal computer in 1981. Maybe not famous in The States but here in The Netherlands an nice and sturdy computer.

Jay Miner's 8bit machines (Atari 400/800) were the most impressive especially if you consider their date of release (1979). They were the first home machines with. -256 colors and a Display list interrupt allowing more than 60 colors on screen -Custom chips, one for Soundand two for Graphics(one of which was a CPU(ANTIC) itself with its own instructions) - Sound chip with PCM capabilities , High Pass filter in two out of four channels -Hardware scrolling , scaling and sprites - Auto boot mode across all mediums (Disk, Cassette, Cartridge). No need for cryptic commands. -USB like peripheral Port (SIO - high speed out of the box). Joe Decuir later participated in the development of the USB port. - Screen Saver -Svideo output

[@RetroDream]

Totally agree, and I didn't put enough focus on this aspect. That's right, the 400/800 had really groundbreaking specs!

[@nickolasgaspar9660]

@@RetroDream Every machine brought something new and innovative on the table so I don't know how many hours your video would end up if you had to mention every single one! The truth is that Jay Miner's work on this 8bit architecture did set standards for the whole industry of multimedia machines to adopt and improve upon them. Great video btw. I never realized how long the list of the 80s machines really was!

[@RetroDream]

Thanks for your interest!

[@TheQueueCumber]

Awesome! So many memories! Machines I had, or friends parents had, or that I lusted after because of a leap in graphics (Apple IIGS Bard’s Tale demo!)… lol. You should do one on the advent of online gaming. That was the next big surge. Late 90s into the late 2000s was another great time to be alive and on computers for gaming between the technology and faster online access. It seemed like I was beta testing a new online game or MMORPG every few weeks when not obsessing on the current best of the best!

[@user-eu9qn6bj6g]

@@RetroDream maybe I’m old but using actual machines, it engages your senses, the touch of the disks, the noises, the flashing lights, even the smell of the disk when you open the case all add up to an experience. I feel the same for cassette, cd (especially caddie ones), record players. Something so analogue about it somehow. I remember when I dad got one back in the day, I was amazed by the 100mb compared to 1.4m floppies I’d been using until then.

1. Vid says it starts with "first computers with widespread sales". But the IMSAI (1975) sold 20,000 units and the Altair (1975) sold 40,000 units, compared to the 65,000 of the Apple III which was included in the vid. No, what marks the three famous 1977 computers as being "first" was they were the first *pre-assembled* computers. IMSAI and Altair were just kits that the buyer had to solder together, though dealers would sometimes assemble them for customers, and eventually Altair itself did start selling pre-assembled units (but not very many). IMSAI, of course, is also notable for having been featured in the film War Games. 2. The term "ISA" was not appropriate for 1987. That term is a marketing term invented by the "gang of nine" EISA group, to distinguish their new slot from others. The term appropriate for 1987 was "AT bus compatible".

[@RetroDream]

Absolutely. Good points. Thanks for mentioning, noted for next time!

[@timlocke3159]

You have the TRS-80 with 128x48, which uses 3x2 custom characters to achieve that. The Commodore PET also had 2x2 custom characters which allowed it to achieve 80x50 resolution.

Nice video. I think this version already contains some bug fixes from the last time, doesn't it? I think the TRS-80 is now fixed and not confused with the later color computer. Maybe worth mentioning would be the SHARP MZ series of computers starting already in the 70's with the MZ-80K and going through MZ-80B, MZ-700, MZ-800 and X1 (since you then have the X68000).

The PC1512 has a max Resolution of 640x200 (CGA) in 16 Colors (rarely used) and the PC1640 had a maximum of 720x348 (Hercules Monitor) or 640x350 (EGA Monitor)

[@RetroDream]

That's correct! Yet the aim here was to indicate the most commonly used, and not max res

[@rubberduck4966]

@@RetroDream I had a 1640 and it mostly did 720x348 because it came with a monochrome Monitor. There is no different res on hercules possible... And with an EGA Monitor one would use 640x350 if possible (Windows, GUI Applications)

23:30 No, the Mac Plus did not have a faster processor; it was exactly the same processor as the previous Mac models. 23:44 The case design was exactly the same as before, just the ports were slightly different. The keyboard now had a built-in numeric keypad and arrow keys. Remember, Steve Jobs had already -been kicked out of- left Apple by this time, so he couldn’t stop these features going in.

28:54 Actually, the base unit came with no graphics card at all. The Apple “TFB” (“Toby Frame Buffer”) card came with base VRAM for only 16 greylevels/colours, upgradeable to 256 greylevels/colours (greylevels on a monochrome monitor, colours on colour monitor, naturally). Another thing the Mac II could was run multiple monitors (via multiple graphics cards) at once, and move/size windows across them.

I noticed an error for the Amiga 1200. It ran with a Motorola 680EC20 at 14 MHz, not 7 MHz. I would have expected to see the first home computer sold with an Intel 80386.

[@RetroDream]

Good points thanks for mentioning

[@timlocke3159]

You have the Acorn BBC Micro with 8 colors and the Acorn Electron with 16 colors. They have the same palette of 16 colors but half of them are the same color but flashing, so there are really only 8 colors on both systems. Also, you have the Acorn BBC Micro with a resolution of 640x256 but the Acorn Electron at 160x256 but the Electron could also do 640x256 the same as the BBC Micro.

[@RetroDream]

Noted for the colors.

[@timlocke3159]

I just noticed you said the Apple II had a relatively affordable price. At 2 1/2 times the price of the TRS-80 and PET, it was not relatively affordable. Also, you said it was, "the first widely popular microcomputer", which is easily falsifiable by looking at sales figures for the Apple II and the TRS-80 which vastly outsold the Apple II cumulatively by 40 to 1 in 1977, to 2 to 1 in 1982, and finally 1 to 1 after the Apple IIe came out in 1983. Interestingly, in the TRS-80 description, you admit it's sales set a record, contrary to what you said about the Apple II's popularity. As you said correctly, the Commodore PET was far behind both of them. The only benefits the PET had over the Apple II and TRS-80 was the screen and tape drive were included giving the consumer the best bang for the buck, and that it had a Microsoft BASIC from the start. In every other way the PET was inferior.

[@RetroDream]

You're certainly right. I tried my best with a very limited number of words per machine which excluded the possibility for nuances and subtleties. It's definitely not a perfect script yet but hopefully it will take a more refined shape with each iteration. By relatively affordable I meant as compared to the Apple III and Lisa for instance.

[@timlocke3159]

The Commodore PET/CBM 4000 couldn't do 640x200. It was limited to 40x25 characters on screen with 8x8 pixel characters, giving 320x200 but it wasn't a bitmap mode and the characters could not be modified. Using characters in the ROM with a 2x2 grid, a "bitmap" of 80x50 was achievable.

You have the Amstrad CPC 464 with a resolution of 160x200 and 16 colours but it could do up to 640x200 resolution, although in only 2 colours. You have the Acorn BBC Micro with a resolution of 640x256 and 8 colours, even though it can only do 2 colours in 640x256 mode. This is inconsistent. I think the best solution for consistency would be to show the highest resolution (regardless of colours) and the highest simultaneous colours (regardless of resolution).

[@RetroDream]

I don't agree. My goal is to show the most commonly used configuration

I noticed you are rounding off the MHz but the IBM PC was 4.77 MHz so it should round to 4.8 MHz, which you did for the IBM PC XT. Also, the Tandy Color Computer is 0.895 MHz so should round to 0.9 MHz. The rounding is inconsistent.

IDK if somebody already mentioned this, but you completely skipped the Atari 1200XL. Considering that it only lasted 3 or 4 months, that's not surprising, but it at least paved the way for the 600XL and 800XL. It was killed by incompatibility with 400/800 software which became a warning to Atari which ensured that the later XL and XE machines remained mostly compatible. This was also a detriment to innovation as many advanced versions of the 8-bit line never saw the light of day.

[@RetroDream]

You're right, at a time I was considering doing, but in the end I decided it was too close to the 600/800 so that it was either this or that.

[@Metastate12]

Is the price of PC-8801 $3000? It's 228,000 yen, so it's probably less than $1,000.

in money of back then it is

The Apple Macintosh ran at 7.8336 MHz so should be rounded to 7.8 MHz, not 7 MHz.

[@RetroDream]

That one is my bad.

[@lawrencedoliveiro9104]

That was the nominal speed. As I recall, 1 in 4 memory cycles were stolen by the video/audio refresh circuitry (no VRAM). So you have to deduct 25% off the effective CPU speed for that.

[@timlocke3159]

@@lawrencedoliveiro9104 It's normal for stats to show the physical speed, not the nominal speed. Almost every system loses clock cycles to other circuitry.

The Amiga 1200s 68020 ran faster than 7mhz

[@RetroDream]

That's 2 times faster yes
