23. From: "Peter Wong" <pitz.wong@gmail.com>
I've also been making use of solid-state solutions, specifically with the
Apple IIgs.
One particular category is making use of SCSI. I use the Apple II High
Speed Card on my Apple IIgs for these solutions (though this would be
limited to ProDos and HFS disk partitions, and does not apply to DOS 3.3
disk images).
* http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD
This is the adapter that I make use of the most. A disk image(s) containing
multiple ProDos partitions can be loaded into a microSD card by mounting
the raw microSD card in modern machines (e.g., Windows) and using some
raw read/write utility like dd.exe. I use CiderPress in Windows to load and
extract files from the microSD directly.
* SCSI/IDE adapter
There are a series of SCSI-IDE adapters like those marketed as ACARD
AEC-xxxx adapters. They serve as a bridge from SCSI to IDE. With these
adapters, you just need an additional cheap $5 IDE-CF or IDE-SD adapter
to make it a true solid state solution.
* SCSI/CF adapters
An older set of SCSI/CF adapters, the Microtech PCD-xxxx set of adapters,
also work. It doesn't bridge to IDE, but bridges directly to the CF (or SD)
cards inserted in the adapters.
* SCSI CDROM or MO or ZIP?
Not exactly solid-state, but you can boot GS/OS from a CDROM (sorta like
a Live CD). There are some additional details in my blog, and this
mechanism has been around for a long time.
All the SCSI-based solutions also work with other platforms that make use
of SCSI (older Macs, NeXT). One caveat with the SCSI solutions is that with
the Apple SCSI cards, SCSI termination power is not provided by the card,
unless the card is modded to do so. Another device in the SCSI chain has
to provide SCSI termination power.
Then there's the regular direct bridge to IDE approach. The Focus card or
the MicroDrive cards offer an IDE interface. With the cheap IDE-CF or IDE-
SD adapters added, this also becomes a solid-state solution. I've
personally tried the Focus card, but not the MicroDrive cards. The CFFA
cards also work the same way -- the older version pre-CFFA3000 offers an
IDE interface aside from the direct CF slot. For several years, this has been
my preferred solid-state solution, booting my IIgs from the CF card.
The new CFFA3000 card still offers the CF slot which I boot from, but also
adds the capability to have disk images stored on a USB thumbdrive.
These disk images can be mapped to the Apple slot/drive combinations and
they appear as regular DISK II or Smartport drives. In short, this card is
awesome.
One category which is getting popular lately is to provide solid-state
solutions through the external disk interfaces (e.g., the DISK II Interface card
connectors, or through the DB-19 disk connectors). Several vendors, from
Bulgaria, to Korea, to Japan (see csa2 discussions) regularly offer these in
eBay or direct purchase. Another domestic (U.S.) one (http://
www.bigmessowires.com/2015/04/01/apple-ii-800k-3-5-disk-emulation/) is
also in the works. I've only had the experience with the UNISDISK from
Nishida Radio. It's also a great solution, but since I prefer an internal
solution over an external solution, I mostly use the SCSI2SD or the CFFA
approach.
Another (maybe a little off-topic) category is remote-booting from an
AppleShare system. AppleShare servers were initially used in Macs, but
there is a port to Linux (netatalk). Steven Hirsch and Geoff Body have
extensive backgrounds on this approach. The Linux box is essentially a file
server, and the Linux box could run off a solid state device like an SD card
or a USB thumb drive. I think Ivan Drucker has ported it to the Raspberry
Pi. The IIgs natively supports AppleShare servers; the IIe needs the Apple
Workstation card.
Those are all my thoughts on solid-state solutions. Hope it helps.

24. From: "Steve Chamberlin" <steve@bigmessowires.com>
I'm relatively new to the Apple II world, but I wanted to call your
attention to some work I've been doing recently with a disk
emulator I designed called Floppy Emu. It's an external board
with a microcontroller and a CPLD - a versatile combination that
enables it to emulate many different kinds of floppy drives with
only a firmware change. Disk images are stored on a SD card in
Disk Copy 4.2, 2MG, or other standard image formats. You can
also pop the SD card in a modern PC and open the image files
with Ciderpress or other tools.
Originally Floppy Emu emulated 800K Macintosh floppies, and
I've since added 400K and 1.44MB Mac floppies, Mac HD20
hard drive, and Lisa 400K and 800K floppies.
Then just a few weeks ago, I started looking at Apple II floppy
emulation, and ProDOS 800K disk emulation is now working on
the Apple IIgs. There are still some kinks to work out, and a
ROM 3 compatibility issue, but I'm optimistic it will all get sorted
out. I've also researched 5.25 inch 140K floppy emulation, as
well as Smart Port emulation of Apple II hard drives, and both
should be possible with a firmware update on the current
Floppy Emu hardware. In the end, my goal is to have a single
device that works on any Apple II, Lisa, or Macintosh - for
floppy emulation as well as hard disk emulation where possible
(HD20 or SmartPort).
The Floppy Emu product page is here - http://
www.bigmessowires.com/macintosh-floppy-emu/ This page
doesn't yet mention the Apple II support, since it's still "beta"
You can follow the development history in a series of a few
dozen blog posts going back 3.5 years here - http://
www.bigmessowires.com/category/macintosh-floppy-emu/ The
most recent ones are all about the Apple II work.
Best,
Steve

25. From: "Henry S. Courbis" <support@reactivemicro.com>
My name is Henry from ReActiveMicro. I am writing to you in
reference to your posting on CSA2 asking for HDD experience
with solid state storage on the Apple II.
I happen to sell the MicroDrive/Turbo card and would be glad to
answer any questions you may have regarding the device. It is
the fastest controller out there since it's the only one to use
DMA reads and writes. It allows booting to all volumes while
resetting using the Open-Apple key and the volume number or
letter (if over 9 volumes). You can even 'skip' the MDT on boot
by holding down the ESC key. This is useful if the MDT is
installed in Slot 7 and you want to boot to the Floppy Drive.
Cards are being sold on eBay for $175USD, plug-and-play
ready for the enhanced IIe and IIgs.
Any other questions, please don't hesitate to ask.

27. Apple ][ Collectors Anonymous
The Apple ][ Collector’s Twelve Step Program
1. We admit we are powerless over Apple ][ collecting – that our collection has become unmanageable.
2. We have come to believe that a power supply greatly re-capped can restore us to sanity.
3. We have made a decision to turn our will and our lives over to the care of Woz as we understand Him.
4. We will make a searching and fearless inventory of our Apple ][ collection.
5. We admit to Woz, to ourselves, and to one other Apple ][ collector the exact extent of our collection.
6. We are entirely ready to have Woz remove all defects of programming.
7. We humbly ask Woz to sign our collection.
8. We will make a list of all persons we have harmed and bored with our collecting, especially our spouses
and children.
9. We will make direct amends to such people wherever possible, except when to do so would injure our
collection.
10. We will continue to take a collection inventory, and when we are missing something, promptly bid on it.
11. We will seek through PEEKs and POKEs to improve our contact with Woz as we understood Him,
praying only for more of His signatures and a power supply with no magic smoke.
12. Having had a spiritual awakening as the result of these steps, we will try to carry this message to other
Apple ][ collectors, and to practice these principles in all our affairs.
