Is there a folding client for this???

I've been working on resurrecting my first childhood computer. This beast is almost 30 years old and I spent many long hours typing in and programming BASIC on this machine. Lots of good memories.

For grins, I wanted to calculate what kind of folding performance it would have.

It's hard to find benchmarks for the 1.77 MHz Z-80 that powered this, but I was able to find a single precision whetstone test for both a Z-80 and Core 2 which is enough to get in the ballpark.

Of course, you have to overlook the other problems like memory (48K), storage (88K floppies), internet, etc. but we can pretend a 1.77 MHz Z-80 could fold...

The bottom line is that my 3.4 GHz C2D is approximately 22,415,384 times faster than a 1.77 GHz Z-80 :)

Comparing this to the output of the standard Windows client, this means that if you folded for 24 hours a day, 7 days a week, for 100 YEARS, you'd have completed 0.814 points.

Probably not the quickest way to the Top 100 :)


 
BTW, as crazy as 22 million times faster sounds, it's really only a 75.8% speed increase every year for 30 years which is certainly within the realm of possibility!

If only my 401k would increase at 75.8% annually :) (especially in light of the market sell-off today)
 
No doubt! Lots of memories.

It's serial #004266 of at least 50,000 that were made.

That's probably $2000-$2500 of 1979 dollar goodness sitting there. Those floppies
were close to $500 each and held 88KB. You could use a hole punch and make them
double sided though :)

I remember my Dad also had one of the very first dot-matrix printers in the
Paper Tiger. He used to program the TRS-80 to command that printer at the
single dot level to output high quality sheet music. Big-time stuff back in the day...
 
I could not afford the luxury of a trash-80 so I had to suffer with a VIC-20 with its awsome 1mhz processor, 3.4 K (yes K) of ram and a cassette tape drive. I did increase the memory with home made boards to 27.4K. Was I ever so happy when I upgraded to a commodore 64.:rolleyes:

Yep, the Commodore 64 was a very cool computer for the time. I had one of those as well. And then the natural progression to the Amiga 1000 which was mind blowing in terms of being ahead of its time technology wise.

I really enjoy firing up some of the computer emulators to explore those machines again. The C64 (and VIC-20) emulation is essentially perfect these days and the Amiga emulation isn't far behind, at least for the original graphics chipset.
 
You guys are old. :eek:

My first pc was a 60 MHz Pentium (back when Pentium was hot stuff), with a 4x CD-ROM. We played with Windows 3.11 for months before our free upgrade to 95.
 
Might want to limit cpu usage to 75% for heat concerns ya know.... :D

I'm not old. I remember when we got our first color TV just a week before Neil Armstrong walked on the moon (yes I know it was in B/W)
 
First application I ever wrote was on a Colecovision Adam.. Only took about 7000 lines of code and about 40 minutes to load from the cassette tape :). Oh and it was just a flash animation (not flash like you are thinking the image just flashed) that lasted about 30 seconds and has some really bad midi music in the background.. Ahh those were the days.. best part was that you could code for 5 hours get tired, play donkey kong and go back to coding without ever really having to get up :)
 
You know if I break out the C64 I will pass all of youz! Bow down earth beings of less than normal size and strength! The C64 is the first and only computer that anyone ever needed. Shutup or I'll fast hackem a copy of Karateka. WAYAA!!!

Yes ! But I went through 3 of those before I learned that you should NEVER touch the I/O port with your fingers ! I bought the first one in 1982 for $600 plus $350 for the Commodore 12' composite monitor. The last one I bought (can't remember what year) for $130 . My only Commodore 1950model monitor still works ! (After both kids using at college with a VCR to watch TV with :) ) I still love to PEEK & POKE -- even though it's been a while since I've done it -- :D

Yeah, I hear getting married will do that...:(

Earliest machine I had was a C64 that I used to write papers in the third grade. Black and yellow monitor, OS loaded off 3.5" floppies. The first TV my family bought was intended for use as a color monitor for that machine (but it didn't have composite input, so it sat unused in a corner for quite a while). And I'm only 21.
