Connect Internal Floppy drive to external port as DF1 on A500

[Rooster]

If ya can't find it, lemme know, and I'll crack my external A500 drive open and see if there's any circut boards in there..  If there is and it's simple, could always take photos/document marked parts, etc...  This being a last resort kinda thing, of course  This like a project/goal thing for ya, or do ya not wanna search ebay for external drives?

Okies - I'll crack it apart tomorrow and get some pics up on a website and link ya..  As well as the obvious mentioning in here as to whether there'a an PCB's inside!

There is in fact a board that the cable hooks up to.. I'll post a link to the pics in a few.  Pretty small/easy board, from the looks, but certainly not a straight-through connection.

I submitted the photos to the website here, in the Assorted Hardware and Monitors section, but I'm guessing they have to be approved since they aren't showing up yet..

So, check out http://www.lanfest.dyndns.org/a1010/ for a direct link to the photos (note for archival purposes this will not be a perminent link, only temporary till they get accepted here...)

There four components, not counting connectors on the PCB:

PR1:  A resistor network - The hardest to describe, so the last two shots on my website detail the writings on it.  To me, looks like:  5X102J, which I though would be a 102 (1000ohm) 5 pin network, however there's 6 pins..  Maybe the 6th is the main power into it, then 5 outs...   *Note I did not send these pics to the site here, just on my temp. location.

U1:  7300E1 (fab/datecode)
     M74LS74AP

U2:  735400
     M53238P

C1:  10.4%
     50 V

I can provide more, detailed pics of the board alone, if you are going to try and recreate one..  I don't mind one bit, just didn't do it yet as I'm lazy, and not a fan of excessive work if it's unnecessary



Interesting sidepoint..  The ribbon cable that attaches from the PCB to the floppy - There is a second header for a ribbon cable right behind the one in use..  Possibly a dual external was in their minds??
