Old vs New cpu's

My trusty old pentium 100 completed a w/u in 1,983,296.00 seconds (cpu time) for its massive 138.55 credits.
The other machine which also did this w/u had a cpu time of 52.95 seconds - a tad faster.
They landed on the moon with less power than a pentium 100. So what has been done with all this extra processing power?.

Well lots I'm sure.

Anyway ..... shame I cannot get boinc to run on my window 1 machine with its cyrix fastmath co-processor.

My Intel Macs do more in one day than my PPC (601 - 604) machines did in 6 years.

There is a huge difference in how the code runs on Intel chips. The PPC versions were painfully slow.

i remember an article in "Sky and Telescope"
that said the new 386 was just as powerful as
a cray supercomputer of three years before...

i still have a 286 buried somewhere.

Don't have my old copies of DOS, but do have 6.22, COA and WFWG disks:
Old MS disks

I simply forgot - my first home computer was with IIRC Siemens 8086 (or 8088 ?) 4.77 MHz CPU, 640 KB RAM, HDD 20 MB, 5" floppy, DOS 3.30
(but I leaved this computer in another town and it was probably thrown in junk)

It was Bulgarian made ;)
(very bad and unstable - many capacitors "saved" in factory,
very bad monitor - "Black and White" (Green phosphor) flicker all the time - cold soldering)

The brand-name was Pravetz-16

" Pravets (Bulgarian: Правец, also transliterated as Pravetz or Pravec) is a town in central western Bulgaria, located approximately 60 km from the capital Sofia.
Bulgarians associate the town with its (now closed) computer manufacturing plant and with the birthplace of Bulgaria's last communist dictator, Todor Zhivkov."

(Earlier I worked on (not mine but at university) Apple II+ using 1 MHz 8-bit 6502 CPU (BASIC, 6502 Assembler), and on Mainframes (Bulgarian made) similar to IBM 360 (Fortran compiler))

Once these old cpus were kings. Then thrown away as scrap. Along with the rest of the kit - including software and winchester hard drives.

I still find it amusing to get one of these old motherboards setup and running. Often needing an ISA disk controller card etc. I have several 80286 machines with their 20 meg hard disks running CDOS or win 1/2/3/3.11. All pretty useless today.
And a machine that takes a month to do a w/u is a waste of electricity. But having said that I started up the Dual socket 7 machine. With its two P75 cpus it will race thru 2 w/u in a month.

I guess in the future boinc will evolve so that these machines will be useless too. Along with the pentium 60 machine as well. Its not much of a loss. But progress seems to leave a heap of useless rubbish behind it.

Good old dos 6.22, compaired with dos 2 or 3 it was a huge leap forward. Well a step anyway

You make me wish I'd kept my 486DX2/66 that all of a sudden one day (only a few years ago) said: ok not going to boot up to the lo-level splash screen no more.

Compared to some of the machines mentioned above it would have been like quadGTX590s...

Mmm quad GTX590s...
