JiffyDOS chip arrived <sigh> no instructions
« on: October 07, 2009, 06:14:19 PM »
After spending 10 minutes searching the net (UGH!) not a single JiffyDOS resource explains what location to install the damn chip! And of course, it didn't come with instructions.

I have I.C.'s located at U3, U4 and U5. I don't really feel like playing multiple choice here! lol

Perhaps Jim Brain's JiffyDos site can help.  I found a whole list of user manuals at:

Thanks both! Didn't think Jim would have that - and his site is a pain to navigate (IMO). U4 was all I needed to know  :-)

Cheers Tone007!  I'll be sure to write how fast or not this thing is. I'm sure its old hat to you guys, but it's brand new to me. Haven't an 8-bit Commie since the 80's, nearly shat myself at how slow stuff loads into it! I thought there was something wrong with all my systems... lol

Get a manual, pronto! Either buy one or print one from the web. If you are going to use real floppy drives, you will need roms for them too.
Someone has to state the obvious and that someone is me!

I couldn't believe how long things took to load either when I went back to the 64.  Now I look at it as part of the "retro experience."  Ha!

Seriously,  I've gotten used to the load time, though a set of Jiffy's would be nice.  I've got a couple of Epyx Fast Load carts for those days I'm feeling the need for a booster.

Standard loading times were painfully slow, even worse if you were unlucky enough to be stuck with a tape drive. Amazing how much difference JiffyDOS (or even a simple Fastload cartridge) makes.

Jim is actually authorized to distribute JiffyDOS now, whereas most other "distributors" are pirating it.

JiffyDOS is definitely nice to have with one of Jim's uIEC devices.

Shoot, the one I just bought was from Basicwayne on ePay - out of MI. Hopefully he's legit. Looked like a professional enough kit. $25 shipped or thereabouts.

So, ummm, yeah.... just got through installing her and the switch. WOW! I'm floored. This little upgrade has got to be one of the more important mods you can do for the C64. Simply incredible. I'm aware of the function key calls - haven't used them yet, but damn does this thing load FAST now. I'm super happy with it.

And lastly, gotta tell you... since deciding to get back into the older systems, a year ago with the Atari 8-bit... nearly game for game; the graphics, sounds, text and overall "feel" of the Commodore experience BLOWS away the A8. There's a huge argument over on Atariage where some hardcore Atari people are getting into the nuts and bolts of the hardware - what it's capable of, etc. Totally missing the point. It doesn't matter what something (or somebody for that matter) is capable of - if it was never implemented, it doesn't mean a hill of beans! Every single arcade conversion I've seen/played yet between the two, the C64 wins hands down.

Bottom line: I can't believe it took me this long to get back into the C64. SID is even more awesome than I remember. Most A8 games look like Atari 2600 games compared to the C64. Single coloured sprites, thick, chunky/blocky graphics and unlike the 2600, the A8 has drab colours. Blech.

Anyone wanna buy a mint Atari XEGS after that fine endorsement? lol  I still like my A8's and (think) I will be keeping one, but...  lol

I adore my 64s!

I've got a 64C with a 1571,1541-II and a 1581 connected to my 1084s.  I've also got a couple of SXs and some older 64s.  One of these days I need to get the 128 set up again!

So many computers, so little time!

Don't forget to pick up a C64 video to S-Video cable (if you haven't already).  I can't believe how good my C128 looks on a 42" screen using the S-Video in.  :D

He's the biggest offender at the moment, just about everything he sells is copied/counterfeit.

Yeah, I should. And I've got a real nice 1702 with that input also. I have noticed something kinda strange about the video though on my breadbox C64. Half the time you turn it on, you can see faint vertical bars - very light striping of sorts. Other half, the picture is solid blue. What gives? During games though, the faint striping seems to go away. Plenty of heat sink compound on that chip and I've left the shielding in there. And oh, I am using the a/v out with the 1702 currently.

Another quick question: what's going on inside that chip that allows the port to act so much quicker? Ditching some verification routines or something else?  

And Tone007, shoot - was afraid of that. Just my luck  :-(

JiffyDos speeds up most disk access by 10 to 15 times by using  a replacement block of code and using all the wires in the cable.
 The story is the C64 and 1541 chips were always capable of fast operation but were slowed down because the little round DIN cable was cheap and widely available whereas the original CBM computers used a cable made only by one manufacturer who couldn't supply enough cables ,and his cables were high priced.

 If you buy nothing else for  a C64 or C128 get JiffyDos.
It is like getting a new machine.
 If you are wealthy or lucky ,get a SuperCPU and REALLY see how a C= program can fly.

Jiffydos is very quick, but if you are trying to archive or copy disks use opencbm or simular on a pc. That is fast. You do need a xm cable and a parallel port though.
