Oceanic OC-118N what Jiffydos?

[retrobazar]

Hello, i'm new in this forum. I'm from italy and apologize for my poor english.
I'm a 128D owner, already have Jiffydos both in 128 and 64 modes and in the 1571 drive. All works fine.

Now I'd like to use an oceanic OC-118N drive as a Device 9 ... I opened it and seen that dos eprom is a 27128 28pins chip. Tested the version and it is CBM DOS 2.6 - 1541

I'd like to add a jiffydos eprom inside the OC-118N but unable to find the proper JD version. I tried several versions, 1541 - C1541 - 1541 II - X1541 (all on 27128 eprom) but nothing, the drive doesn't works.

What's the correct version? can you help me / send me the correct bin file?

Thanks in advance!!!

[Andrew Wiskow]

The correct chip you need is probably the Excellerator+Plus, FSD-2(V1), or FSD-2.  All of these, and other non-CBM drives, are listed on this page of Maurice Randall's site.  Unfortunately, as far as I know, he's the only one who has these chips, and he's not making them available. 

[Andrew Wiskow]

And by the way, don't feel bad about your English...  it's great!

After I visit some friends on Saturday and Sunday, I can dig out a few Excelerators/FSDs and check them out for JiffyDOS.

That'd be great, Robert.  And if you have any of the other non-CBM drives listed on the page I linked to earlier, check them out, too.  So far, the only non-CBM drive that I have in the JiffyDOS collection is the Indus GT.

If you need a rom image of original firmware stored in my oc-118n i can send you the binary file.
But I'm thinking:

my firm is CBM DOS 2.6, seems the same as commodore 1541 drives... why the 1541 jiffydos doesn't works?

[Golan Klinger]

So far, the only non-CBM drive that I have in the JiffyDOS collection is the Indus GT.

I have others but after the expropriation of the ROMs I previously made available, it was decided that it was best not to distribute them.

It is almost a 100% copy of the 1541's ROM which is why the manufacturers of that drive were sued by Commodore. I can confirm that JiffyDOS v5.0 for 1541 will work in that drive. Perhaps you should try burning another EPROM and then test it in a real 1541 to confirm that it works and then test it in the 118N.

[retrobazar]

I tried a jiffydos 5.0 eprom (27128) already mounted in my 1541 drive ... it works in the 1541 but doesn't works in the oc-118n ... but I need to try if the oc-118 eprom works in the 1541 ... I don't know that...

[Golan Klinger]

Trying the OC-118 ROM in the 1541 is a good idea. Just for curiosity's sake you should dump them both and do a diff. Something ain't right here.

[retrobazar]

how to do a diff? I already dumped the oc-118 rom, and have the original 1541 eprom firmware, please explain me how to make a diff thanks!

I think that horse has already been beaten to death.  I do not wish to go back there.  You can either choose to help the Commodore community at large or not.

[retrobazar]

Well, I tried the 1541 eprom in oc-118n and vice-versa, they doesn't works:

The 1541 have 901229-05 firmware, CBM DOS 2.6, it's 8kb (2364 eprom)
the oc-118n have CBM DOS 2.6 of 16KB (27128 eprom)

any comments will be appreciated

I didn't know that.  I have an Indus GT in my CommodoreOne.

Hey guys, what does this mean? What happened in the past?

[Golan Klinger]

Hey guys, what does this mean? What happened in the past?

Andrew may not want to go back there so I'll tell you what happened. When Maurice Randall started taking people's money and not sending them the items they had paid for (quite a different matter than being incommunicado) a group effort was made to collect JiffyDOS ROM images and I made them available to the public. Andrew downloaded the archive, slapped it up on his webpage and started inviting people to download his JiffyDOS collection. This left a bad taste in more than a few people's mouths and that's why now, when new images are located, they're quietly distributed to trusted members of the community. His implying that by not distributing the new images I'm the bad guy who doesn't want to help the community is offensive.

I wish I could say it was an isolated incident but he makes a habit of expropriating the work of others, taking credit for that work and then tirelessly promoting himself as the community-minded guy who made the effort. I've talked to Andrew about the incidents but (evidently) they still irk me.

[retrobazar]

Hello Golan, have you the jiffydos for OC-118N ? Can I buy an eprom from you? already contacted Maurice but no replies... thanks!

[Andrew Wiskow]

Okay, so Golan decided to go back there anyway, so let me follow up his side of the story with my side of the story...

Golan did, indeed, have the collection of JiffyDOS ROMs available for downloading.  But they were posted in a rather obscure location that anyone who was searching for them had no hope of finding.  In an attempt to help the community at large, I merely hosted the collection on my own server.  I never "expropriated" the collection, I never took credit for the collection, and I absolutely never said that the collection was MY collection because that would be totally untrue.  I have added a few additional ROMs to the collection, but I always refer to it as "the collection of JiffyDOS ROMs", not "my collection of JiffyDOS ROMs".  The only intent of posting files on my own server is to help people find things that I, myself, had difficulty in finding.  I hope that others won't go through the same difficulty in finding things that I did, and I've had many people thank me for posting the files that I have.  I always give credit where credit is due whenever possible, and I never try to take credit for things that aren't mine.

If Golan "and others" continue to be irked by what I've done in the past in an effort to help others, I'm sorry.  It's in my nature to help others whenever possible, and I can't stop.

[RobertB]

I never "expropriated" the collection, I never took credit for the collection, and I absolutely never said that the collection was MY collection because that would be totally untrue.

Andrew is correct.  It is neither Golan's collection nor Andrew's collection.

I hope that others won't go through the same difficulty in finding things that I did, and I've had many people thank me for posting the files that I have.  I always give credit where credit is due whenever possible, and I never try to take credit for things that aren't mine.

Also very true.

It's in my nature to help others whenever possible...

Help is good.  No one should complain about that.

Thanks to a kind contribution, OC-118_JiffyDOS_5_(FSD-2_V2)_[27C128].BIN is now included in the collection of JiffyDOS ROMs...  one step closer to a complete collection. 

[retrobazar]

Hello and happy new year!!!

I tried that jiffydos in my OC-118N but unfortunately it doesn't works property, the dos was recognized but too much time to access the disk with red-green flashing led... load error troubles...

[Andrew Wiskow]

That's odd...  The guy that sent it to me said he burned it from the ROM that was in his own OC-118.  The only thing I can think of is that perhaps yours is a different version than his is.  That one's the FSD-2 V2 ROM, so maybe yours needs the FSD-2 V1 ROM.

Hey, does yours have three DIP switches on the bottom?  I had an FSD-2, and it had three switches.  Two of them were to select the drive device number, and the third was to turn JiffyDOS on or off, if it was available (which it wasn't in mine).  If I remember correctly, there was an extra ROM socket, so the standard ROM stayed in one, and the JiffyDOS ROM went in the other.  That's not the case with the OC-118 that this new ROM in the JiffyDOS collection came from, however.  He did send me a couple photos showing the board and JiffyDOS ROM in his drive.  You can see those here:

http://cottonwood.servebbs.com/wiskow/OC-118_1.jpg
http://cottonwood.servebbs.com/wiskow/OC-118_2.jpg

Take a look at these photos and see if they look identical to the drive you have.  If they don't, then chances are, you need a different version of the JiffyDOS ROM.

[retrobazar]

My oc-118 is the V2 version same as http://cottonwood.servebbs.com/wiskow/OC-118_2.jpg, the eprom was recognized as well, but the drive doesn't works properly, it faulty to load files.

I have only 2 switches for device number selection.

however I will try to burn another eprom, maybe is an eprom problem... but my willem eprommer works very fine...

[Andrew Wiskow]

I'm not sure what the problem is then.  From the photos, it appears that he has an original JiffyDOS chip.  Perhaps he made a bad burn of it?
