Hi Chuck, as a general guideline, I'm a big fan of the ten year rule,
though I'd generally be weary still of anything PC based that is
Pentium III and newer, and/or Win95 or newer. Thanks, David

In my hands is a floppy drive pulled from a Sun IPC: a Sony MP-F17W-F1.
Looking at Ebay, I see a floppy from a Macintosh: Sony MP-F75W-02G. Would
this IPC's drive be acceptable for a Mac?

Hello to All on the list,
I need the schematic for the ET-3400A, which is different from the original ET-3400, which I already have.
I have an ET-3400 that does not have the MCM6830A ROM. I have a ET-3400A that uses the 8316 ROM and one that uses a 2716 EPROM, which are interchangable. I want to create an interface circuit that will allow me to use a 2716 EPROM in the ET-3400.
A schematic for the ET3400A will really be appreciated.
Thanks in advance,

I've posted a photo of my Microcomputer Systems Corporation SA4000-to-
GPIB disk controller PCB here:
http://www.sydex.com/durango/msc1088.jpg
This is a large board (12"x19")that contains mostly 74LSxx logic.
The two 24-pin cerdip packages at the top left side are AM2506DC 4-
bit ALUs; the 28-pin package below them is a N8209 (Signetics) 64x9
bipolar RAM. The 40 pin package to the left of them is an Intel 8291
GPIB talker/listener. The
Just thought I'd snap a photo before it went back into its box. The
documentation for the board (just command definitions) is dated 1979.
FWIW,

Hi,
I have one of these cards that I'd like to demo at VCF East
this year. Does anyone have docs and/or software for it?
Thanks,
Bill

The web as subsumed all of this, in an inferior fashion, IMHO.
You will notice that bitsavers looks exactly the same as it did as
an anonymous ftp site on its previous host.
> Should we be working to archive large FTP software repositories?
Absolutely! And try to find old backups that you have.
Make sure to use something that can preserve file dates of the files.
The old recursive ftp programs didn't do this.

OK, I've downloaded some of them now.
They are some of the ugliest, bloated pdf's I've ever seen.
What are you doing to them to make them look so BAD.
"Control Data-Cyber 70 Computer Systems Models 72,73,74,6000 Computer Systems.PDF"
for example, appears to have a mix of six different fonts on a single line, where
there should be one.
The titles are poor.
"IBM System-360 Operating System.pdf" is a program logic manual for the Fortran IV
graphics programming services. At a minimum, you should have the document part number,
date, and the REAL title.
Y27-7152-0_F4_Graphic_Programming_Services_Program_Logic_Sep67.pdf
provides some useful metadata
Look at http://bitsavers.org/pdf for 10,000+ examples of how this SHOULD be done.

Did they 'just work' or was a driver downloaded off the net to make them work?
The curse of Windows is every vendor doing things their own way, and the need
for thousands of incompatible drivers. You can extend this to USB drivers as
well. A USB async adapter can be implemented a bunch of different ways, going
as far back as Anchorchips devices that squirted code onto the adapter, up through
the current reduced cost devices that barely offer any tech docs on how they
work.
Vendors really only care about Windows support, and grudgingly give out info
to driver writers (or they have to reverse engineer the hardware to do it).
They also want to lock you into their device, so they have no interest in common
drivers.
Getting back to the original topic, as long as the protocol for the floppy adapter
is documented so that people can write USB drivers for it for other platforms, it
should not be an issue.
