Quote from: wiskowI never got any thanks from him or anyone else for my efforts on this, and I never asked for anything either.

That can be changed

Thanks for all your efforts! :tummenupp:

Regards WTE

PS: You are right. No one is giving thanks to all the guys who serve the community. And no one should expect any thanks.
But it's always nice to get some

Quote from: pearsoeIs the Jiffy1571D.rom in this archive http://cottonwood.servebbs.com/JiffyDOS.zip the correct ROM for the 1571 drive or is it for the 1571 in the 128D? If it isn't is there somewhere to get the correct ROM for the 1571?

Pearsoe,

I just added the correct ROM for the 1571 to that zip file. I also renamed most of the files so they look more "orderly".

Enjoy.

*I* don't mind, no... But then again, it's not my collection.

My Jiffy Dos is on its way. $35.00 including shipping. Not a bad price?

smf · November 28, 2007, 12:45 AM

anyone got v6 roms for the 1541?

Douglas · November 28, 2007, 02:06 PM

Hello everyone!

Is it really worth it to get Jiffy Dos for the 128 and 1571 drives? I have never used a machine with it installed.

Thanks!!!

Douglas

Absolutely. It speeds up disk access and the wedge speeds you up.

and v6 for the oceanic oc 118n?

does anyone know what the differences are? I'd like to disassemble a v5 and v6, but nobody seems to have both for the same drive.

with maurice not delivering, it seems like they're just going to disappear for ever.

I have v5 and v6 for the 1571... Would that help? I haven't made a dump of the v5 chip, but if you like, I'll make one for you.

yes thank you, that would be very interesting. it might not be conclusive as there might be bugs fixed in one drive that never existed in another, but it should be possible to work out if anything in jiffydos changed significantly.

does anyone know if there was a v5 for the 1581 as well? obviously with those being a tiny bit rarer at the time, there is less chance of one turning up.

Okay... I'll try to make a dump of my v5 chip in the next few days.

On another note... I finally got around to scanning in the JiffyDOS installation instructions that Lord Ronin loaned me. There are now complete scans of the JiffyDOS installation instructions for C64 and 1571 available for downloading on my website at http://mysite.verizon.net/wiskow/ ... Does anyone have any others? Oh... I just looked, and I have the installation instructions for 1541, too... I'll have to add that later. But if anyone has any others that they could add, I'd like to try to put together as complete a set as possible.

For what it's worth. When installing the heat/RF shield on my C128, I noticed 2 heat sink "fingers' were not making good chip contact (just barely) so I removed the cover and bent the fingers for good contact. Not sure if others missed this but anyhow I thought I'd mention it.

Andrew Wiskow · December 03, 2007, 11:44 AM

OK... I made a dump of both versions of JiffyDOS that I have for the 1571 drive. These are both original chips from CMD.

The first one says V5.05 on the label with a copyright date of 1988. On the error channel, it reads as V5.0. The dump is at http://cottonwood.servebbs.com/1571jd5.rom

The second one says V6.01 on the label with a copyright date of 1989. On the error channel, it reads as V6.0. The dump is at http://cottonwood.servebbs.com/1571jd.rom

Let me know what you find as far as differences between the two.

Andrew Wiskow · December 07, 2007, 05:56 AM

The 1541 JiffyDOS installation instructions have now been added to my website.

SMF, have you had a chance to compare those versions of JiffyDOS for the 1571 yet?

I did a quick fc /b and they are quite different, so I'm going to knock up a disassembler that is geared up to the task of generating output that can be compared. With work/bad cold/xmas etc it'll probably be a weekend job.

I certainly understand... This is a very busy time of the year for me, too!

I sent the V5 and V6 JiffyDOS ROM's for the 1571 that I made dumps of to Eslapion, and he says that the V5 appears to be based on the original 1571 ROM (the buggy one, 310654-03), and the V6 appears to be based on the fixed rom (310654-05).

Also... Thanks to Eslapion's kind donations, the Collection of JiffyDOS ROM's that I'm hosting on my website is growing! I've just added the JiffyDOS ROM for NTSC Plus/4, as well as the CMD FD-2000 DOS ROM (yes, I realize that's not JiffyDOS, but it includes JiffyDOS and it's CMD, so what the hell... hehehe). Here's the complete list of everything in the collection so far:

1541
1541-II
SX1541
1571
1571D
1581
C64
C128
SX-64
VIC-20
Plus/4 (NTSC only)
Turbo Master
IndusGT
FD-2000

If anyone has any other JiffyDOS ROM's that they'd like to add to this collection, please contact me! I'd like to try to make this as complete as possible. Thanks go to Golan for the majority of these, and of course to Eslapion for adding to it. To download these, just go to my website, and click on the "Collection of JiffyDOS ROM's" link. Perhaps Lance could also update the copy that he's hosting here??

Enjoy!

Can you provide more than the ones in the zip that andrew is hosting?

StyleCHM · January 15, 2008, 09:57 PM

i havent looked, but Id think we'd have the same files.

What device do you have that isnt in his file?

or are you thinking I have more roms to add to the collection?

I do have a couple of drives that I need to check whether I have a working set for.
But from a software preservation aspect we really need to make sure that all the versions are kept and catalogued.

There are definately a few drives missing and then there are many revisions missing.

What would one set for 1571 plus shipping to the US cost?

StyleCHM · January 16, 2008, 08:29 AM

Ill pm you Michael, but let me check shipping first - it cant be that much for 1 chip plus a switch

The 1571 JiffyDOS chip is autosensing, so no switch is required. All you need is the 27256 or 27C256 EPROM. JiffyDOS for the 1571 and 1581 are the easiest to make.
