Anyone ever heard of it?
Looks like a REALLY old-school floppy.

Just bought out a guy's collection, and man, what a TON of stuff.
Columbia's, Corona's, Compaq Portable I/II's, about 6-8 Kaypros, 6-8 Osbornes (O1, o1a, Execs), a few C=128D and 128DCR's, some C128's, VIC-20's, C64's, a PET of some sort (haven;t yanked it out yet) VIC1575 and MPS803 printers...the list is REALLY long... took a 14' box trailer nearly 3/4 full (volume-wise - center was packed to the ceiling over the tires!!!) to get the stuff home!!!

That's where I ran into this thing. Found a box with a 1541, 1541-II, 1571, and that C-II floppy drive. Has the data connector on the left side (when looking at it from the front)

Any info around?

Terry - I haven't even mentioned 3/4 of it yet!

Paid $700, + about $80-100 in gas driving there and back.

"Quick Glance" problem.

It's not C= - company named "Commander Electronic Systems" if I'm recalling correctly. 1985 manufacture date.

But does it have an IEC (6-pin DIN) or an IEEE (card edge or Centronics-like) connector? Single or dual floppy drive? A picture would be nice if you need some help to identify it.

By the way, 1575? Are you sure you didn't misread 1525 or even 1515? I've never heard of a 1575, whatever it should be.

It's got the DIN connectors, on the side.
Made by Commander Electronic Systems. At quick glance, I thought it was Commodore...figured out later it wasn't (in my follow-up above).

The printer is probably a 1525, then. Mis-remembering, is more like it :D

In any case, it doesn't sound like a CMD, Oceanic, Enhancer, Indus, Blue Chip. I found the Clone II disk drive from HBH Sales Corp. No pics, though.

I'll take a pic when i get home.

Got some 1541-II's, 1571's, and 1541's in the batch.

1 lonely Atari 1050 floppy drive - nothing else Atari in the WHOLE batch!!!
Poor thing! :D

I picked up a handful of Commodore-centric magazines, but I did not find the C-II. It's most likely a clone. There were many clone 1541 drives made, most I never heard of.

It is - "Commander Electronic Systems" is the manufacturer. 1985 datecode I think.

Oh, dang.

Sorry... gimme 5 minutes (well, 10 - gotta undig that box :eek: )

EDIT: OK - Pics attached. sorry about that ;)

Powered it up, but haven;t tried functional test yet.

Funky latching mechanism. Push down, it latches, push down again, it unlatches and door lock pops up.

Thanks for the pictures. It certainly doesn't look like a Commodore clone. If you wish, I could enquire information in other circles, i.e. among Commodore users and collectors if they know about this 3rd party drive. If you power it up, it would be interesting which DOS version it reports.

10 OPEN1,8,15,"UJ":REM RESET DRIVE
15 INPUT#1,E,E$,T,S:REM READ ERROR CHANNEL
20 PRINT E,E$,T,S:CLOSE 1

A standard 1541/1541-II usually reports "CBM DOS V2.6 1541". A 1570/1571 contains DOS V3.0 and so on.

As regarding the latching mechanism, isn't that one of the common types to release the latch by pushing it down once more?

I was just saying it LOOKS strange! Mebbe I need to put a better frontal shot.

I will try the basic commands you listed tomorrow, and report back the results.

I'd be interested to see what you find out about it from other folks, especially C= collectors.

That IS quite interesting... But I have never seen one like it either... I did a few casual Internet searches, but I came up with nothing on it. I, too, would be interested to know what the error channel reads. Be sure to run that BASIC program first thing when you turn the computer on, BTW. :-)

I'll do that tonight when I get home. Any preference on what to use?
C128 / 128D / C64 / Plus4 ?


Tony

Sharkonwheels

How long does it take to get a response? Is is immediate?
I get nothing - not even on a 1541-II.

I tried with:
Plus/4
C16
C64
C128

same results - nothing.

If I reset everything (just in case) I can read the floppy drives,
doing a listing with load "$",8 and then LIST

so both drives work fine when individually plugged in.
But i get absolutely NO response from either drive when I use that basic program.

OK - it works without the ,"UJ"

gives CBM DOS V2.6 1541

That's pretty much what I expected if it was a 1541 clone, which it obviously is. The 1541 clones I've used (FSD-1 and FSD-2) read the same way.

No idea. Here are a few semi-related auctions going on:

Enhancer 2000 on Tradera (Swedish) (http://www.tradera.com/Enhancer_2000_diskdrive_till_vic_20_c64_i_kartong-auktion-47257240). Currency conversion: 1 SEK = $0.15, so current bid about $30 in original box.

Oceanic OC-118 on German eBay (http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=330159947903). It ended with BuyItNow at 40 Euro, which should be about 55 USD.

Indus GT for the Atari 8-bit (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140151969864). It is not quite the same things a Commodore drive, but since the Indus existed on both systems...

I don't know if these figures help you anything at all.

Indus GT....I remember those, and the ads.
Those were the absolute COOLEST looking drives around.

Were they on any other platform besides Atari and Commodore?
Any Apple GT's for example?

Yep:


A flick of its power switch can turn an Atari into a Ferrari. Or an Apple into a Red Hot Apple.

I believe the Commodore version may have been the last one they issued. Apparently the GT contains its own Z80, so no luck in loading 6502 code into the drive memory. I don't know to which extent Atari and Apple disk drives could execute arbitrary code anyway, but the Commodore ones do.

You may be interested in the pictures from George Page's former collection, now owned by Bo Zimmerman:

One could ask yourself how Indus got away with referring to Porsche, Ferrari and other brands. Maybe trade mark owners were not quite as aware back in the days. I doubt they could do that today without striking a license deal with the other brand, like how Acer sells Ferrari branded computers.

I still have one of those sucker around for the Atari. It's beyond all hope of repair, but, you were right, they looked good just sitting there.

Am I the only one to notice the sticker that says "Laser Micro-Systems Inc."?
For some reason, that company name sounds familiar.
You might check the back pages of BYTE magazines from 1984 or 1985.

And I think there's somewhere to do a search for that FCC ID, which might yield some information.

No luck searching for "Laser Micro-Systems, Inc."... And no luck on the FCC ID number search either... FCC's website seems to only search back to 1987, so this device would pre-date that.

As for what it's worth... Well, post it on eBay and find out! ;-)

I hadn't noticed it before, but Glenn Holmer on the cbm-hackers mailing list pointed out that the drive mechanism face looks the same as the Enhancer 2000 drive. He's right! Check it out:

So, for a C= user, was that a good thing?
Were those drives reliable?

I guess they at least SORT OF were, as this one can still read!!

Late follow-up.

Been going through and separating the C= stuff out to get it out the door.
Decided to pop the C-II open, and inside are (2) Mitsubishi M5L2764K 8KB EPROMs. Isn't the 1541 a single 8K? Or 2?

Anyone want a dump of the ROMs?

The drive is strange as well - Chinon F051.
Has (1) 6502, (2) 6522's and a Toshiba TMM2016P

Drive has a 20-pin cable going to the PCB, reminiscent of the Apple cable, and an unpopulated area for a 2nd connector!
There's also 2 solder pads bridged, as well.

The 1541 has 2x8 = 16K ROM. It also has one 6502 and two 6522's, so in that respect your drive is no oddball. I don't know the model numbers of 5.25" drive mechs.

I'm sure the Commodore community would appreciate a ROM dump. It could also be used to determine how compatible it is.

Sharkonwheels

I looked, and Zimmer's site, which has the firmware, is a bit confusing.
Some of the links in the 1541 section are a bit wierd. Says 1541, links to 1540-xxxx
Stuff like that.

I dumped them, and have them with me.
PM me with who to email them to

(2) 8kb .bin files attached.

These are straight dumps, on a Logical Systems writer/reader (XPro 48?)

I'm sure they're fine. As Glenn Holmer on the cbm-hackers list pointed out, visually your drive resembles an Enhancer. It might be worthwhile to compare ROM dumps between those two drives in particular, given that someone dumped the Enhancer.
