Those of you that have been involved with computers for a while will probably find this site rather interesting- Computer magazine archives.

I spent quite a bit of time going through several old issues of Rainbow magazine- the first computer our family had was a Tandy Colour Computer.
I remember Dad spending most of one night (and probably will in to the early hours of the next morning) typing out a Parachute programme, then saving it. Unlike other computers, the Tandy Colour Computer made use of readily available cassette players/recorders. However you had to get the volume & tone settings just right, otherwise you couldn't read back the saved data.
And the next day, Dad had to type it out all over again, when he was unable to re-load it (again), so the next day he bought the floppy drive and controller (which from memory cost twice as much as the computer itself did).
And there was the time there was a programme we really wanted to run, but we didn't have the memory- so he bought the 64k upgrade kit (half a dozen or so RAM chips, a length of insulated wire, and some photocopied instructions for what went where.

And seeing all those old commands again-

Hi Grant,

My first "real" computer was the Tandy CoCo III. It had 128K RAM which I upgraded to 512K. I got the Multi-pak (a 4 port bus expander) which held my floppy drive and HDD controllers, plus other stuff I cannot remember anymore. I learned OS-9 Level 2, did C programming (text editor in one window, compiler in a second and tested the program in a third) and more on it. I had a plethora of the old Rainbow magazines, several boxes, until they ended publication. My first time on the Internet was on the CoCo. Photos would take a lifetime to load. lol :)

My first computer was a glorified calculator, but it could be programmed in BASIC. It came with a thermal printer unit that it plugged into to save battery and a cassette tape player/recorder for storing programs.

Those were the days... :)

Have a great day! :)

oh the memories. The coco (Tandy Color Computer) was my first machine. I used the cassette player to save programs for a while before my dad splurged for the disk drive. He did go out the next day to buy more memory for the machine though as I was soon writing programs that didn't fit in 4k. I'll have to thank my dad for that when I call him today.

If memory serves, I had a 5 1/4 and a 3 1/2 floppy drives and a 10 MB HDD. I mostly did stuff in OS-9. I was able to read and write directly to a disk; I believe that had to be done to the file descriptors for the 640x400 windowing I used. That was the highest resolution that the GIMI chip could do, but one had to have 512 MB of RAM to achieve it. No, that can't be right. I seem to remember a resolution of 800 x 600. Perhaps that was the reason for the file descriptor hack. Been so long... lol :) Google is your friend, use it (talking to myself). ;)

Have a great day! :)

I had an Atari 400, the 1st computer with a chipset, this version of the computer had 2 slots, the 800 had 4 slots.
The cpu in one slot, memory in the rest, Corvus made a hdd for the 800 as I remember.
Sorry it's so big, this is the only available size I could find.

Those four DB9 type ports are joystick ports, the 13pin SIO port is not shown here.
SIO is Serial Input Output, serial ports were on a daisy chained device called the 850, each device was essentially a computer unto itself.

Except for the red button, Mine looked like this one and I had 48K, yep My computer was modded before anyone ever heard of the term.

The original cpu card, also the CTIA/GTIA chip and Antic chips were here, along with the 6502 cpu, this is the PAL version, NTSC would I think be about the same maybe.

Hi Zoom,

Yep, I modded one of my CoCo3s as well. I drilled holes and installed a cooling fan for the power transformer and regulator and I replaced the original 6809 CPU with, I believe it was, a 6309 which ran slightly faster than Motorola's 6809. I had to de-solder the CPU from the MB and installed a socket for the new one. For the RAM upgrade I had to pull the original 4 RAM chips.

From Wikipedia:

The Hitachi 6309 was an enhanced version of the 6809 with extra registers and additional instructions, including block move, additional multiply instructions and hardware-implemented division. It was used in unofficially-upgraded Tandy Color Computer 3 computers and a version of OS-9 was written to take advantages of the 6309's extra features: NitrOS-9.

Something else of interest:

The design team's prediction was, in reality, incorrect, as the market for ROM modules never materialized: Motorola's only released example of a ROM'd software module was the MC6839 floating-point ROM. (The industry solved the problem of integrating code modules from multiple separate sources by using automatic relocating linkers and loaders—which is still the solution used today—instead of using relocatable ROM modules.) However, the decisions made by the design team yielded a very powerful processor and made possible advanced operating systems like OS-9 and UniFlex, which took advantage of the position-independence, re-entrancy orientated nature of the 6809 to create multi-user multitasking operating systems.

Try that with MS-DOG, er, I mean MS-DOS. ;)

Yep, those were the days! :)

Have a great day! :)

Greetings,

Step 1 and 2 are complete.

Step 1: Order a new AiO for my CPU. - Done

Step 2: Install said AiO into PC. - Done

Step 3: Swap the EVGA fans for the front mounted case fans and use the EVGA for case fans. I do not like EVGAs fan design. One of the fans blades are scraping slightly on the grill in the top of the case.

Step 4: As yet I'm undecided if I'm going to use the software from EVGA for fan control or not. I'm leaning toward letting the bios settings deal with that, they currently are anyway.
To heck with the RGB!

Step 5: Download and install SETI and start crunching!

I used CPUID CPU-Z to stress the CPU. Temps did not go above the low 50s. I only ran it for about a minute, perhaps longer testing is in order. Much satisfied with those temps though. :)

Have a great day! :)

You need to stress test longer than a minute to get steady state cpu temps. For an AIO, I would say at minimum, you need to run for 10-20 minutes to see where the system temp under full BOINC load is going to fall out.

Hi Keith,

Yeah, I decided to do that after I fix the fan situation. Thanks for the info though. :)

Have a great day! :)

[edit]
Scratch the fan swap. I need to order 2 new fans. Case fans are 120mm AiO fans are 140mm. I unplugged the noisy fan, the other is on the CPU fan connector. At idle the temps are in the mid to high 20s with just the one fan. Should be ok as long as I don't do the stress test again. ;)

I've never liked 3rd party fan control, except for SIV doing gpu fan control back in my Windows days. Most mobo BIOS have a pretty well fleshed out cpu and system fan control these days with either pre-configured speed/temp curves or the ability to set manual speed/temp curves for cpu and system fan speeds. Some of the better BIOS' have individual system fan header speed control.

Why destroy the joy of seeing how hot your CPU will really get :)

While I have no proof, I expect if you want to get some idea before you start crunching you probably should run the stress test for 15 minutes to give it a chance to both heat up and to stabilize.

Don't forget to buy high static pressure fans and not just any other 140mm fan if it is to be put on a AiO radiator (just in case you didn't know)

On the table in the living room, there lies some two connectors meant for that of external hard disks, where the cover became opened.

One is for IDE, while the other is for SATA, and I suspect I blew both of these, for only using the wrong power adapters.

These are next only small devices, being hand held, for only that of connecting disks to the power and data cables, possibly internally only.

So while the electronics for the device itself, and here the hard disk, could be found on each separate disk, it should not be any architecture either,
for just that of a card for such, and here meaning a hard disk controller, if not directly coming with the motherboard either.

Make it such a thing nowadays, and it really becomes such a thing, for that of both sound, network, and also disks, and still internally, for only the motherboard,
except for also the graphics cards as well, still needing a separate slot for each.

Perhaps it could be still "computer on a chip" for such a thing, and next also the motherboard as well, because each processor type should also need its own board.

That again becomes the separate discussion here, except for other things being said as well, and next not forgetting both temperature, and also undervolt as well,
for only that of failures of sorts, which could be still happening.

I will get back to the rest of it later on.

Hi Rick,

I did not know that, yet I chose a fan that covers static pressure thing. How do a couple of these sound? Read that the ML fans are good for both case and radiators.

Thanks for learnin' me something new! :)

Have a great day! :)

Siran

P.S.: My other fan is starting to make a clicking sound now. :(

Step 3 is done and I'm happy to say the Corsair fans I got are a dream! They are quiet even when the BIOS revs them up.

Step 4 done, left the fans to the BIOS.

Step 5: Download and install SETI. Will do that after a more thorough CPU stress test to check temps, minimum of 10 minutes, probably tomorrow morning.

After I swapped the fans out I ran a CPU stress test for 5 minutes. The temps barely climbed into the 50s; highest I saw was 52. Most temps stayed in the high 40s to very low 50s. Needless to say, at this point in time I am very happy with this upgrade. And QUIET! This PC is so much quieter now even when the fans rev up.

Have a great day everyone and thank you so much for the information and advice sent my way. :)

Yes, the Corsair ML140 fans are a good compromise between airflow and static pressure. The do get a bit loud when at full throat. The Noctua NF-A14 IPPC 2000 fans push more air at better static pressure and are much quieter at full throat mainly because their top speed is 2000 versus the ML top speed of 2400 rpm.

I'm using 2 Noctua NF-A12 IPPC 3000 fans on My Captain 240EX cpu water cooler, that'll be 3 when I put the 360EX and the E5-1650 v2 cpu into operation, 3000rpm doesn't bother Me.

Greetings,

I ran the CPU stress for 11 minutes and BAM! Started out in the mid to upper 50s then settled in to high 40s low 50s. Once again, while running, I saw no temps above 52C after the initial run in the 50s.

I have BOINC installed and running on 50% CPU. I have the GPU disabled in the settings, but...

This is weird. The way I understand it is if a discreet video card is installed the onboard video is disabled by the BIOS. My MB has onboard video. And, I have a WU running on the Intel onboard video and not the GTX 1050Ti. Yet I have the GPU computing disabled in settings. Since I initially got GPU WUs, I assume that those WUs will be crunched and I will get no more GPU WUs?

I'm also thinking that if the onboard GPU can be used even if disabled due to discreet card, I can have the Intel GPU enabled in my settings. Would that be a fair assessment?

Also, I had several (about 5 or 6) WUs done in 15-17 seconds and waiting for validation. All others are taking better than an hour to run. Any clues?

Have a great day! :)

No. The iGPU will only be disabled if you disable it in the BIOS.

I'm also thinking that if the onboard GPU can be used even if disabled due to discreet card, I can have the Intel GPU enabled in my settings.

If you disable the iGPU in the BIOS then it will cease to exist as far as the system is concerned.
If you don't have a high resolution monitor (ie 4k), it would be best to use the iGPU to drive your display & leave the discrete card for crunching. That way you can have very aggressive settings for processing GPU WUs, but it will have no impact on system responsiveness.
Just make sure "Use Intel GPU" is not selected in the Seti project settings (it will also result in more WUs processed per hour).

No. The iGPU will only be disabled if you disable it in the BIOS.

That depends. I have a couple of Dell Optiplex machines (business desktop range) where the iGPU is disabled unconditionally when you install a discrete GPU.
