On the CD topics, I've seen several comments about the new Kodak photo-CD format which is not ISO9660 compatible. Does anyone know anything about this turn of events?
#83351From: Betty Clay/SYSOPDec 31, 1992 9:23 PM
CDROM drives can be made to read the Kodak PhotoCD and regular CD's as well. Their format is not the same as ISO9660, but drives that can read ISO9660 can read it. PhotoCD can be single session or multisession. All drives prior to the most recent ComDex show were either not compatible or they were single session. (This session business is brought about by the necessity to write a new directory each time new material is written to the drive, so multi-session really means it can read multiple directories.) I believe that the format is proprietary, so we probably won't be seeing it in a text file on CIS.

Somewhere I was reading about PhotoCD. I seem to recall reading that it uses CDROM-XA (like sub-directories) and that Kodak was going to sell driver packages for IBM & MACs (about $49) so that (I assume) most CDROM drives could read PhotoCD's. IF CDTV can read CDROM-XA disks then all we should need is a driver!? later!

I've been reading messages in the CDROM forum for quite a while, and they have a great deal of information about Photo CD. They have several text files about the requirements for reading it, etc. It does require CDROM-XA, but the XA drives (as best I can recall) can be single or multi-session. Only the most recent drives can handle the multiple sessions that will be required for most PhotoCD disks. I believe that Toshiba's 3301 can have a ROM upgrade that will make it compatible, but those earlier than the 3301 cannot. Wouldn't you know that I have a 3201B.
#83555From: Mark SterlingJan 2, 1993 4:12 PM
Betty, That is very close to correct. The Toshiba 3301 series is single-session Photo-CD ready and can be upgraded to multi-session. For $100 they install a new rom, new small circuit board (?) and supply a new device driver for your Mac or PeeCee ( What? You're not using either to run your CD-Rom?). Oh well, there is no software for Amy that will handle Photo-CD anyway. Call Kodak and bug them now (1-800-242-2424 ext.77) Hee-hee. Goin' AP6 …..Mark Sterling6

Mark, I called KODAK and asked about software for my C= Amiga MultiMedia computer. 'No', was their reply no plans to support it, 'as the market is a very slim one'. However, the person I spoke to did say that all calls were recorded and that that each one would help to make a decision on future plans. So, it is in our best interest that we urge everyone to call and ask for support. So to ALL that read this thread. Call Kodak and ask them now (1-800-242-2424 ext.77) for software for your Commodore Amiga Multimedia workstation. Chris

A fellow I met on another BBS works at Kodak and uses Amigas at home. At work, he says, all the Kodak tech types are Macinfreaks. He has failed several times to get his shop to bring in an Amiga for evaluation but apparently finally succeeded the other day. Meanwhile, he asked about Photo CD support for Amiga, and got the same "no plans" answer you did. So everyone phone that 800 Kodak number and let your voices be heard.
#84291From: Christopher TolmieJan 8, 1993 6:54 PM
Ron, Let's keep that Kodak number from scrolling off of here for a while. When you comment on it again, insert the number.<g> Kodak Photo-CD for Info call 1-800-242-2424 ext.77 Chris
#84349From: Ron LegroJan 9, 1993 10:28 AM
Chris: You must mean that number to call to urge Kodak to offer Photo-CD for Amiga — 800-242-2424 ext. 77. I'm pretty sure it hasn't scrolled off yet. <g>
#84358From: Christopher TolmieJan 9, 1993 11:33 AM
Ron, Yup! Kodak Photo-CD for Info call 1-800-242-2424 ext.77 That is the correct number to call if you want to ask/urge KODAK to offer Photo-CD support for the Amiga line of computers. g> Chris
#84361From: Andy FinkelJan 9, 1993 12:04 PM
Say, what was that number again ? andy
#84436From: Mark D. ManesJan 9, 1993 6:42 PM
Ron, No. I think you mean this number (800) 242-2424 Ext 77. -mark= (grin…)
#84496From: Christopher TolmieJan 9, 1993 11:53 PM
Mark, Do you think if we get KODAK to support PHOTO CDROM for the Amiga, that COMMODORE would think about adding their own support for the medium? I mean CDROM in general? Or do you think the reason they're ignoring its existence in the X000 series is because their latest and greatest model can't fit one in it's poorly dimensioned bay? The way things are going KODAK might write the drivers for PHOTO CD, and C= will ignore the whole idea. Making KODAK's original decision to ignore the Amiga a valid one. But still I'd call KODAK at (800) 242-2424 Ext 77 and ask for the drivers. Too bad we can't do the same thing with C=, but they REALLY tend to ignore us. Chris

I am definately going to call: Kodak PhotoCD at 1-800-242-2424 ext. 77 I called them during the summer and I am very glad to see that PhotoCD is getting some attention in the Amiga forums. Been thinking of getting a Kodak player but I would MUCH rather be able to import to my Amiga. Question to all: I've been thinking why not use something like CrossPC on the amiga to run PCAcess s/w from Kadak to read PhotoCD disks then convert to amiga useable format ? Problem: I think Kodak only has Windows vers. and Mac (no DOS vers.) so far.

I have no doubt at all that Kodak would love to see PhotoCD implemented on as wide a range of systems as possible … and that includes Amiga CDTV. But, PhotoCD is a combined project between Kodak and Philips … and Philips own CD-I … and, although I'd love to see it happen, I can't see Philips being too keen to let Commodore have a licence to support PhotoCD on their main rival system. Certainly not at this stage anyway.
#84685From: Carl HansenJan 11, 1993 7:03 AM
Mike- You hit the nail right on the head. I've talked with Amiga reps and that is indeed the problem. So pressure on Kodak is the only possability because they have a terrific investment in PhotoCD. Carl
#84364From: Mark SterlingJan 9, 1993 12:27 PM
That's the number I called. I too registered my vote for a port to the Amiga. They sent a developer's info pack. $795 for full developer support. Goin' AP6 …..Mark Sterling6
#84366From: Greg SeelyJan 9, 1993 12:48 PM
When CDTV first came out C= did show CDTV reading PHOTO CD.
#84390From: Alex BakerJan 9, 1993 2:54 PM
I wonder whether Kodak is more interested in selling software, or Photo CD's? If it were me, I'd almost give the reader software away, or make the specs public knowledge. After all, a person will probably only buy one driver, but plenty of Photo CD's. Their attitude sounds somewhat like saying they won't sell, or let you sell, a 10 cent plastic adapter so that you can use their film in your camera. The money is in the CD's not the software. Razor companies sell the razors cheap, so you'll buy the blades. – Alex

If I read between the lines, it means that when you want to put new pictures on the disk, they actually burn them on the same disk instead of doing a new disk. Hence the need for multiple directories. Is this correct?
#83375From: Don Curtis/SYSOPJan 1, 1993 12:48 AM
Yes, that's correct…you don't need to put all 100 pictures on the disk at once. You can put them on any number of times up to the point where you finally end up with 100 on the disk.
#83442From: John Toebes/SYSOPJan 1, 1993 3:36 PM
Is it that expensive for the CD's? I would have thought that just copying to a new CD would have been the way to go. Does the effect of actually writing to the disk in a second/third/… pass do anything to lessen the lifetime of the disk?
#83476From: Don Curtis/SYSOPJan 2, 1993 1:04 AM
I'm not sure of the end pricing of the blank CD's themselves, I'd guess that retail pricing is in the few dollars category. One local dealer is charging anywhere from $1.25/picture to $0.85/picture to add pictures to a Photo-CD, depends on how many you want to add at one time. I seem to recall they said that throw the CD in for free if you put at least 10 on it the first time (at $1.25 ea.). But, figure a typical roll of film taken by Joe(Jane) Average. Out of the 24 shots, they will only want to put about 5 or 10 on at a time. They won't want to wait until they have 100 ready to go…that could take quite a while for most folks. So at best…they'd need 10 CD's and at worst 20 CDs if the dealer simply created a new CD each time. While individually they're not that much, at 10 to 20 intermediate CD's used to get to the final product…not very cost effective I'd say. Professionals, or serious amature photographers are a different story, in several ways. They may only like one out of a roll of 36 shots, but by the same token…they may be able to come up with 100 shots they want put on a Cd fairly quickly…say less than a week. So they'd more than likely save up and get all 100 put on at once…since their per picture cost is lower if they're all done at once, and the blank CD would be throw in at no additional cost.
#83494From: Betty Clay/SYSOPJan 2, 1993 3:11 AM
That's the way I understand it, John. You can have pictures put on the disk in as many different sessions as you like, but there must be a new directory each time, because they cannot add items to the directories already on the disk. For this reason, the disk format must allow for the reading of multiple directories. Most CDROM drives currently in use read a single directory only. You might want to read a few of the files from the CDROM forum, such as KODAK.TXT. It tells a great deal about what is required for reading the disks, and was placed there by a representative from Kodak.
