This document discusses various solid state storage solutions for retrocomputers. It begins by introducing the author and their experience with retro computing. It then categorizes and describes different types of solid state devices and interfaces that can be used, including emulators, adapters, and server-based solutions. Updates to the Floppy Emu device are highlighted. Resources for disk images, benchmarks, and other retrocomputing tools are also listed. In conclusion, it acknowledges other organizers and developers for their contributions to preserving retrocomputing.

3. My Retro Solid State Story
Semi Virtual Diskette
Focus Card with IDE to Compact
Flash
CFFA3000
SCSI Card Reader
SCSI to Compact Flash and SD
Floppy Emu
UNISDISK Air
4. Why Solid State?
Vintage magnetic media can
fail (bit rot, mould, physical
damage)
Mechanical drives can fail
Access to media from modern
computers
Difficulty sourcing new media
Convenience/flexibility
5. Types of Solid State Storage
for Retro Computers
Compact Flash
SD and its variants
USB
Servers, other devices acting as
storage devices
Custom devices
I’m technically including some
mechanical media
6. Types of Solid State Solutions
for Retro Computers
Device emulators
Interface adaptors
Server-style solutions
7. Device emulators/
controllers
Semi Virtual Diskette
CFFA/CFFA3000
UNISDISK/UNISDISK Air
Focus Card
MicroDrive/Turbo
Classic IDE
X/Profile
Smartport Virtual Hard Drive
Audio Sources
Floppy Emu
8. Semi-Virtual Diskette (SVD)
Originally designed for TRS-80
Disk drive emulator, disk
images loaded over serial link
from modern computer
256KB built-in memory
Apple ][ support through
adaptor cable
Low availability originally, no
longer available
http://www.rothfus.com/SVD/
9. CFFA3000
Hard drive, SmartPort and two-drive floppy interface emulation
On screen controls
CF and USB storage
Optional external
switches to cycle
through disk images
Difficult to get
(2017 run on the cards)
NB: CFFA1 is a version
for the Apple 1

10. UNISDISK/UNISDISK Air
Emulates 5¼" and
SmartPort devices
UNISDISK Air Series uses
Toshiba FlashAir SD card to
incorporate a web server for
image transfer and
management

11. Focus card
An early (apparently the first)
IDE controller for slotted
Apple ][s (][, ][+, //e, IIgs)
44 pin IDE connector
Block level access to media
Optional rails to hold
2.5" drive in place
Can power 2.5" drive
Not strictly solid state, but often used with an IDE to CF adaptor

12. MicroDrive/Turbo
IDE controller for the Apple IIgs
40 pin IDE connector
Dual IDE support
Block level access to media
Supports DMA
Includes a dual CF adaptor
Requires ROM1 or ROM3
Not strictly solid state, but most often used with an IDE to CF adaptor
http://www.reactivemicro.com/product_info.php?products_id=34
13. Classic IDE
IDE controller for the Apple ][,
Apple //e and Apple IIgs
40 pin IDE connector
Dual IDE support
Block level access to media
Supports DMA
Not strictly solid state, but most often used with an IDE to CF adaptor

14. X/Profile
Replaces proprietary drive interface
device in Profile drive cases with
Compact Flash or IDE drive
http://sigmasevensystems.com/xprofile
15. Smartport Virtual Hard
Drive
SmartPort device for
mounting hard drive images
from USB storage
Very hard to get a hold of
http://pcedric3.free.fr/
SmartportVHD/
16. Audio Sources
Use any audio source with
digitised cassette-style data
in place of cassette drive
Cheap and easy, but not
particularly fast
17. Floppy Emu
Originally designed as
floppy drive emulator for
early Macs
Firmware is upgradable for enhanced functionality and additional device
emulation
Emulates an HD20 on external floppy port of compatible early Mac
models (sizes larger than 20MB supported)
Emulates both 5¼" and 3½" floppy drives for the Apple ][
Emulates SmartPort hard drives on the Apple IIc/IIgs
Liron support+ProDOS 2.4.1 brings mass storage to pre-//e machines

disks
Compact Flash to IDE (40 and 44 pin)
Compact Flash to SCSI
SCSI2SD is popular
