Fizzbinn’s Finds

Recommended Posts

I managed to pick up an external portable Sony 6X CD-ROM Discman PRD-650MC for my PowerBook 2400/180 setup, original box and all parts but no manual or drivers.

I did the ResEdit trick on the Apple drivers and got it to work except for eject. The disk unmounts but then quickly remounts, if I time pressing the “Open” button just right it’s good but more often I’m too late or early and get an error that I’m sure isn’t great.
 

Anyone have a copy of the original drivers? Ideas where I might find them?  I tried web.archive.org with no luck.

Nice Discman - I like how it still looks like a consumer model but is data capable.  You might need to search through .jp/Japanese sites on archive, to find the file you need.

I have a Sony PRD-250 with the Powerbook SCSI cable, but never found the Mac install disk.  There is a FWB CD-ROM toolkit that may provide the functionality that you need.  Not sure if it will work, but it was suggested in a Google groups discussion.  No idea what version(s) to try.

I spent more time on the Internet archive and think I found the drivers!

 

Device drivers for Sony's PRD-Series CD-ROM Discman Products

mac_prd20.sit (402 kB):
Version 2.0 for Apple Macintosh

 

Finding the right Sony website and year was the trick. Assuming the drivers test out okay, I'll see about uploading them somewhere (Macintosh Garden?). The bare drives seem to be fairly common on eBay, the Mac specific SCSI cable not so much though...

The driver software is actually CD Mounter Pro 3.2.0 by Software Architects. Works great, tested via my PowerBook 1400 (running 8.6) as my 2400 isn’t booting for some reason... grrr.

Opportunistically adding to my boxed Apple OS collection when I find them on eBay for a non-crazy price.

Still looking for:

 

System 5.0 - Not holding my breath, recently went for $305 on eBay...

System 7.1

Sysyem 7 Pro

Mac OS 8.0

Mac OS 8.6 - Not sure this was sold on its own...

Mac OS X 10.0 

Mac OS X 10.4 - Last one in a full size box I believe.

I'm not sure that it was.  If it wassold as a retail package, it probably wouldn't have been packaged in it's own unique box, but rather as an upgrade disk included with 8.5.

 

I think it may also had been offered as a free downloadable update to 8.5,?  Apple's FTP site was available on the Wayback Machine last I knew, so perhaps I can check....

UPDATE:  I checked, and it does look like 8.6 was offered as a downloadable updater for 8.5.x.  I'm not sure if it was shipped in a retail package, but I kinda doubt it.

I turned my attention to my IIsi over the weekend (still can’t figure out the voodoo to bring back my 2400c :-( ) and played with the Applied Engineering QuickSilver card I recently acquired with manual and floppy!

The 32k static RAM Cache is the most interesting thing about it as I have other adapters that add an FPU. I decided to run some benchmarks via Norton Utilities System Info 3.2.1 (System 7.0.1) with the original clock chip and overclocked to 25Mhz with 50Mhz clock chip, with and without the card/cache and FPU:

A neat progression in performance improvement (essentially doubling over stock). The best performance run “Macintosh IIsi/25 + FPU/Cache/D” came when I remembered the Memory Control Panel Disk Cache trick of setting it to 1024k to use up the slower soldered on motherboard 1MB of RAM with disk cache forcing the video memory, OS and all other apps to use the faster RAM in the SIMM slots. If you have the memory a pretty significant improvement on its own! :-)

 

CPU comparison with the other system in this version of Norton Utilities System Info:

Sony 6X CD-ROM Discman PRD-650MC update - So from the Internet Archive Sony product specs I was able to find out what the Sony model was for the optional internal "Rechargable Lithium-Ion Battery" mentioned on the box: Sony LIP-12

 

Surprisingly you can still get new ones (3rd party) on Amazon!

https://www.amazon.com/gp/product/B07WDW85LX/

 

Looks like it should work with the similar PRD-250MC Sony 4X CD-ROM Discman as well. If only replacement PowerBook batteries were so easy to find! (I guess being used in a bunch of other higher volume Sony products helps...)
