Christopher...I stand corrected. From:
The original Lisa had dual 'Twiggy' 5-1/4" floppy drives, which were quite unreliable, and which was soon replaced by the Lisa 2. The Lisa 2 and Lisa 2/5 were essentially the same machine as the original Lisa with the exception that the dual 'Twiggy' floppy drives were replaced with a single 400k 3-1/2" floppy drive made by Sony to Apple's specifications.
I'm remembering the Lisa 2 3-1/2" drives were not Twiggy drives. Turns out the Twiggy drives were famously unreliable.
Interesting bit of folklore: http://www.folklore.org/StoryView.py?project=Macintosh&story=Hide_Under_This_Desk.txt

Bummer, I guess my old Lisa will have to wait for Retrolution 5. BTW, anyone know where to purchase a replacement Twiggy drive? Oh, that's right, Lisa didn't use Twiggy.

Runtime Retrolution 4 Release
Develop Software for Platforms Past and Present
Edinburgh Scotland, April 1st 2004
Runtime Revolution today announces the release of Retrolution 4, the developer
tool for computer platforms past and present. Retrolution includes support for
a selection of platforms dating from the mid-1900's to the present day and
covers most major graphic and chip architectures.
Announcing the release, 92 year old Rt. unRev. Kevin Miller CEO of Runtime Revolution said "I can remember when the transistor was just a glint in the milkman's eye. Since then we've seen the advent of 4 bit computer systems through to the state of the art G5" While semi-drugged and undergoing a hip replacement
operation, Miller added, "Retrolution's stacks and punched card development system now make it even easier for developers of all abilities to write software for platforms big and room sized!"
Retrolution 4 adds support for the following platforms:
*Atari 8-bit, including XL and XE
*Apple I (Apple II coming soon)
*Commodore Pet and C64
*LEO: Lyon's Electronic Office (support for certain bakery products only)
*Atari ST
*Acorn Atom and Archimedes (prior to RISC OS 3 only)
*ENIAC
*Dragon 64
*Oric 1, Atmos and Stratos
*Sinclair ZX80, ZX81, Spectrum support to follow shortly.
*Texas Instruments TI99/4A
*Microsoft Windows 1
*Tandy Radioshack TRS-80 (green screen only)
*Hanimex Pencil II
*MicroBee
*Heathkit EC-1 Analogue Valve Vacuum Computer
*Seattle Computer Gazelle (Zebra and Giraffe support to follow)
*Beattie Bunion 64 Colour Computer
*Open University Hektor 2
*Dick Smith Cat
Daffid Blanket of the UK Home Office Immigration Service said "We've been using
punched cards since the year dot, This new release means we don't need to discard
our state of the art IT systems which include ENIAC, MicroBee and LEO. Instead
we can keep on using them and our trusty stack of punched cards."
Retrolution 4 makes development easy by forcing the developer to program in
binary and to manually punch the holes in the cards. This latest release adds a
whole range of features including:
*Multimedia support with up to 1 channel beep-based sound
*3D graphics, monochrome wireframe with resolutions of up to 64 by 48 pixels
*Ability to use compiled external libraries written in BASIC, 6502 and 6809
assembler
*Support for upper and lowercase letters, except for the letter P
*Support for all numbers from 0 to 9, except 6
*Databases up to 3 records in size, with one field
*Secure data encryption protocols. Each letter is encoded using the next letter
in the alphabet. Support for Z due in 2007, numbers in 2009
*Ability to build standalones in 14 days, allowing you to go on holiday while
Retrolution gets on with the job
*Sync with the Osborne 1 handheld computer
Retrolution 4 is priced at $999.95 and is available on reel-to-reel tape, pre-programmed valve
bank, cassette, punched card and 8 inch floppy disk from all good computer
stores.
