Re: How to transform a Disk II card to handle 13-sec?

[Toinet <antoine.vignau@laposte.net>]

Really big thanks to all of you for your answers.

Please find some close-up photos at http://www.brutaldeluxe.fr/public/switch1316/

The chips are:
pic 1: 341-0009-01 (P5 13-sec) & 341-0027-00 (P5 16-sec) / with a
switch
pic 2: 341-0009 (P5 13-sec again?) & 341-0028-01 (P6 16-sec) / no
switch
pic 3: the two parts with the ending connector (which I suppose need
to be plugged into the Disk II controller card)

If I want a functioning set, I need to purchase and solder a switch,
if the chip 341-0009 is well-placed, your thoughts?

Why did I ask?
I have plenty of Washington Apple Pi disks which are 13-sec based and
I'd like to boot them.
I do not want to use MUFFIN13 or BOOT13 but live the same experience
as my "ancestors"

The second reason is that I'd like to write a GS/OS driver for 13-sec
disks (AppleDisk5.13) and remove the code I've added on the
AppleDisk5.25 driver on brutaldeluxe.fr with the set of FSTs I
delivered to the community.
I believe it would be better to separate layers and offer a dedicated
driver instead of patching the existing driver. I already own a
working DOS 3.2 FST, it would marry well with a dedicated 13-sec disk
driver (instead of patching the 16-sec driver). That is especially
true for emulated environments. The behavior of my GS/OS driver is not
perfect on emulated machines, whereas it works well on real machines
only. So, if I want to offer the best user-experience: separate layers
(FSTs and drivers)

Thanks again,
