| Mar 3, 2018 at 5:07 | comment | added | Jamie Hanrahan | As with Raffz - I wasn't saying you were wrong. I was only providing additional info (since, as you say, there is not room in one reply). Not surprising they weren't mentioned previously as they're not as historically interesting to most as the 6600 and later. (Really beautiful consoles though!) I happened to work on some of the 3000 series so I have some personal interest and just thought I'd toss in that detail. That is all. | |
| Mar 3, 2018 at 4:18 | comment | added | KJ Seefried | @JamieHanrahan If you read beyond the first sentence, I did say that CDC made 24 & 48 bit machines. You aren't allowed enough characters in a reply to explicitly name every machine they made, and I assume anyone interested can use google. | |
| Mar 3, 2018 at 1:48 | comment | added | Jamie Hanrahan | I was adding information. I didn't say you were wrong. | |
| Mar 3, 2018 at 0:01 | comment | added | Raffzahn | Check again, @JamieHanrahan, I did refer the 6000 series. | |
| Mar 2, 2018 at 23:51 | comment | added | Jamie Hanrahan | CDC was not all 60 bit - the "lower 3000" and "upper 3000" series were 24 and 48 bit, resp. | |

| Mar 2, 2018 at 1:49 | comment | added | Raffzahn | @KJSeefried You're right, wrong wording. IBM (and some other) used 36 Bit, CDC was 60 - BTW all 6000s, including the 6700. Changed it. | |
| Mar 2, 2018 at 1:42 | comment | added | KJ Seefried | What CDC machine was 36-bit? The 6600 thru Cybers were 60-bit until the 64-bit 180/200/205 series. They also made 48, 24, 16 and 12 bit machines. The Cyber PPUs were 12-bit. Cybers packed 10 6-bit chars to the word as 'display code' (CDCs almost-ASCII-with-crazy-warts) on NOS. There was a 12-bit encoding that allowed lower case that Plato used. Cybers had a dedicated shift unit that helped access characters. You could also push a lot of user interface out to the PPUs, so for some programs the PPU offloaded character handling (like block mode 3270 terminals, but with more smarts). | |

| Mar 1, 2018 at 20:26 | comment | added | Raffzahn | @JamieHanrahan Word Processing: While the machine wasn't realy designed for it, it's still a computer and can be programmed to do much it wasn't optimal for. I once did real time sound/voice procesing on a /370. Also not exactly the machine designed for such, stillm, ge got it working :). For the 'number crunching', did you note the little remark about that? | |
| Mar 1, 2018 at 20:23 | comment | added | Raffzahn | @Jules You're right. sorry. | |

| Mar 1, 2018 at 19:29 | comment | added | Jamie Hanrahan | Using the -8 for text processing was not all that unheard-of. A whole lot of PDP-8's were used by newspapers for typesetting, using the 6-bit TTS (TeleTypeSetting) code. DEC had a software package for this and sold a bundled -8 configuration. WPS-8 came later when Diablo printers and floppy disks became cheap enough, and was very popular. I would also comment that the "real number crunching" ability of a PDP-8 was pretty darn limited, even for its day. | |
| Mar 1, 2018 at 15:29 | comment | added | Jules | "Word processing was the application the PDP-8 was designed for" -- I assume, given the context of the rest of your answer, that you mean wasn't rather than was. | |
