The '''Apple Lisa 2/5''' was a configuration of the [[Apple Lisa|Lisa 2]] bundled with an external 5 MB ProFile hard drive, released in January 1984.<ref>{{cite web |url=https://apple-history.com/lisa |title=Apple Lisa |publisher=Apple History |access-date=2026-02-09}}</ref> It replaced the original Lisa (Lisa 1) with its troublesome Twiggy floppy drives, offering a more reliable 3.5-inch Sony floppy drive and lower price point.
The '''Apple Lisa 2/5''' is the [[Apple Lisa 2]] with an external ProFile hard disk. It was announced in January 1984 at US$3,495, alongside the [[Apple Lisa 2/10|Lisa 2/10]] and the Macintosh. Like every Lisa 2 it has one Sony 3.5-inch drive in place of the original Lisa's two Twiggy drives.<ref name="chm">Hansen Hsu, [https://computerhistory.org/blog/the-lisa-apples-most-influential-failure/ "The Lisa: Apple's Most Influential Failure"], Computer History Museum, January 19, 2023.</ref>


== Overview ==
Apple's service manual defines the 2/5 as "a Lisa 2 with a 5 or 10 megabyte ProFile (external hard disk) connected to the built-in parallel port in back of the Lisa 2". Once a ProFile is connected, a Lisa 2 "becomes Lisa 2/5".<ref name="lisatp">Apple Computer, ''Apple Service Technical Procedures: Lisa/Macintosh XL'' (Lisa Level I Technical Procedures, #072-0085, pages revised to June 1987).

The Lisa 2/5 represented Apple's effort to make the Lisa more affordable and reliable. The "2/5" designation indicated the Lisa 2 hardware configuration paired with a 5 MB external ProFile drive. This configuration was the more affordable option compared to the [[Apple Lisa 2/10|Lisa 2/10]], which included an internal 10 MB Widget drive.
== Hardware ==
The Lisa 2/5 uses the Lisa 2 boards: power supply 661-93108 (the same part as the Lisa 1 US supply), motherboard 661-93106 and I/O board 661-93198. The [[Apple Lisa 2/10|Lisa 2/10]] has its own power supply, motherboard and I/O board.<ref name="lisal1">Apple Computer, ''Lisa Level 1 Technical Procedures'', #072-0085, March 1985, Illustrated Parts Lists (Lisa 1.0, Lisa 2, Lisa 2/10).

The Lisa 2/5 used a single 400 KB Sony 3.5-inch floppy drive, replacing the dual Twiggy 5.25-inch drives of the Lisa 1. The Sony mechanism was more reliable and used the same format as early Macintosh computers.
 
The external ProFile drive connects to the parallel port on the rear of the unit. Apple's error code '''51''' is "Parallel port VIA", which confirms the port is driven by a VIA and points the first replacement at the I/O board.<ref name="lisal1">Apple Computer, ''Apple Lisa Level 1 Technical Procedures'' (hosted here: [[Apple Lisa Level 1 Technical Procedures Mar85]]): Lisa Set-up 2.6 "Checking the Battery Switch"; Lisa 2 Diagnostics 5 "Interpreting the Boot ROM"; Lisa Troubleshooting Guide 6 and Appendix D "Start-up Error Codes"; Video Repair Procedures; and the Lisa 1, Lisa 2, Lisa 2/5, Lisa 2/10 and Macintosh XL Illustrated Parts Lists.</ref>

'''661-73172'''.<ref name="lisal1" />
 
'''Apple publishes no rail tolerance and no power-supply adjustment procedure for the Lisa.''' The
only adjustments in the Level 1 procedures are video ones — horizontal phase, brightness and
contrast, yoke and trim magnets.<ref name="lisal1" /> Note also that Apple's video fault table lists
'''"a sizzling noise coming from Lisa"''' and '''"power supply trips (turns off and on)"''' with
'''brightness and contrast adjustment as the first two remedies''', ahead of replacing the supply
— so a Lisa that trips is not automatically a supply fault.

Apple's parts lists confirm that the Lisa 2/10 has a different power supply, motherboard and I/O
The Lisa 2 motherboard has three DB-25 connectors: two serial (Apple's "RS232 port A" and "port B") and one parallel.<ref name="lisatp" /> The I/O board carries the battery pack and no resistor at R-47; its disk controller ROM is 341-0290 rev. B at location 1-A.<ref name="lisatp" /> Apple's configuration table gives the Lisa 2 the "5 amp" power supply rated at 1.2 A AC input.<ref name="lisatp" />
board from the Lisa 1 and Lisa 2.<ref name="lisal1" /> '''Supply current ratings and a "DataPower"
designation were previously given here and could not be sourced'''; the part numbers above are
checkable and the amperages were not.
 
A row claiming the Lisa 2/5 uses "a discrete Woz Machine" disk controller and only the 2/10 an
IWM has also been removed: nothing held here supports a split between the two Lisa 2
configurations on that point, and both read the same Sony 3.5-inch mechanism.
 
== Software Compatibility ==
 
The Lisa 2/5 could run:
* '''Lisa OS''' — Original Lisa operating system
* '''Lisa Office System''' — Integrated office suite (LisaWrite, LisaCalc, LisaDraw, etc.)
* '''MacWorks''' — Macintosh compatibility environment allowing Mac software to run on Lisa hardware
* '''Xenix''' — Microsoft's UNIX variant (with appropriate configuration)
 
== General Maintenance ==
 
For detailed maintenance practices including cleaning, PRAM battery management, power supply care, and CRT handling, refer to the [[Apple Lisa General Maintenance]] page.
 
== The I/O-board battery switch ==
 
Before treating a Lisa that has lost its clock as faulty, check the switch. Apple's set-up
procedure: remove the back panel, find '''the set of four batteries on the lower right side of the
I/O board''', and '''make sure the switch next to them is set to ON (toward the left)'''.<ref name="lisal1" />
A Lisa shipped or serviced with that switch off will not keep time and is not broken.
 
The pack itself should come out of any machine being restored — see
[[Apple Lisa Troubleshooting]] and
[[Battery Explosion, Capacitor or Corrosion Damage]].
 
== Troubleshooting ==


A comprehensive troubleshooting guide addressing power issues, self-test error codes, display problems, and storage failures is available on the [[Apple Lisa Troubleshooting]] page.
Apple's owner's guide gives the micro disk drive as 400 KB formatted and the external hard disk as 5 MB formatted, and the same cabinet, power and display figures for all three Lisa 2 models.<ref name="og84">Apple Computer, ''Lisa 2 Owner's Guide'', ©1983, 1984, "Which Lisa 2 System Do You Have?" p. 3; specifications pp. 62-63. Hosted as [[Apple Lisa 2 Owners Guide 1984]].</ref>


== Capacitor Replacement ==
With one memory board the machine has 512 KB and with two, 1 MB; two boards are needed to run the diagnostic diskette and the Lisa Workshop.<ref name="lisatp" />


The Lisa 2/5 contains electrolytic capacitors and a class-X mains safety capacitor that require replacement for long-term reliability. See the [[Apple Lisa Capacitor Replacement Guide]] for detailed specifications and procedures.
== ProFile and software ==
Up to six more ProFiles can be added on optional parallel interface cards, and software boots from the micro disk drive or a ProFile.<ref name="lisatp" /> The Lisa Office System must be installed on the ProFile; Apple told technicians to upgrade every installation to version 3.1. Applications installed on the ProFile are serialised to one Lisa, so if the ProFile is moved to another Lisa the Office System starts but the applications will not open. The Office System and tools take about 2.5 MB of the ProFile. MacWorks can share the ProFile with the Office System, and on the Lisa 2/5 it supports only the built-in parallel port.<ref name="lisatp" />

The external ProFile drive included with the Lisa 2/5 was a 5 MB hard drive with its own Z8 microprocessor and error-sparing capabilities. ProFile drives were also prone to capacitor failures in their power supplies and should be recapped when servicing a Lisa system.

Modern alternatives to the ProFile include:

The Apple Lisa 2/5 is the Apple Lisa 2 with an external ProFile hard disk. It was announced in January 1984 at US$3,495, alongside the Lisa 2/10 and the Macintosh. Like every Lisa 2 it has one Sony 3.5-inch drive in place of the original Lisa's two Twiggy drives.[1]

Apple's service manual defines the 2/5 as "a Lisa 2 with a 5 or 10 megabyte ProFile (external hard disk) connected to the built-in parallel port in back of the Lisa 2". Once a ProFile is connected, a Lisa 2 "becomes Lisa 2/5".[3]

Hardware

[edit | edit source]

The Lisa 2/5 uses the Lisa 2 boards: power supply 661-93108 (the same part as the Lisa 1 US supply), motherboard 661-93106 and I/O board 661-93198. The Lisa 2/10 has its own power supply, motherboard and I/O board.[5]

Lisa models compared[5][3]
Feature Lisa 1 Lisa 2/5 Lisa 2/10
Floppy drives Two 5.25-inch Twiggy One 3.5-inch, 400 KB One 3.5-inch, 400 KB
Hard disk External ProFile External ProFile Internal 10 MB
Parallel port External External Internal only
Power supply 661-93108 (US), 661-93149 (European) 661-93108 661-73172

I/O board 661-93104 661-93198 661-93171

The Lisa 2 motherboard has three DB-25 connectors: two serial (Apple's "RS232 port A" and "port B") and one parallel.[3] The I/O board carries the battery pack and no resistor at R-47; its disk controller ROM is 341-0290 rev. B at location 1-A.[3] Apple's configuration table gives the Lisa 2 the "5 amp" power supply rated at 1.2 A AC input.[3]

Apple's owner's guide gives the micro disk drive as 400 KB formatted and the external hard disk as 5 MB formatted, and the same cabinet, power and display figures for all three Lisa 2 models.[4]

With one memory board the machine has 512 KB and with two, 1 MB; two boards are needed to run the diagnostic diskette and the Lisa Workshop.[3]

ProFile and software

[edit | edit source]

Up to six more ProFiles can be added on optional parallel interface cards, and software boots from the micro disk drive or a ProFile.[3] The Lisa Office System must be installed on the ProFile; Apple told technicians to upgrade every installation to version 3.1. Applications installed on the ProFile are serialised to one Lisa, so if the ProFile is moved to another Lisa the Office System starts but the applications will not open. The Office System and tools take about 2.5 MB of the ProFile. MacWorks can share the ProFile with the Office System, and on the Lisa 2/5 it supports only the built-in parallel port.[3]

Battery switch

[edit | edit source]

Apple's set-up procedure: remove the back panel, find the set of four batteries on the lower right side of the I/O board, and make sure the switch next to them is set to ON (toward the left).[3] The pack is a 4.8 V NiCd that keeps the clock running when the Lisa is unplugged.[6] Remove the cells from a stored machine before powering it up; see Apple Lisa Capacitor Replacement Guide and Battery Explosion, Capacitor or Corrosion Damage.

Diagnostics

[edit | edit source]

An unmodified Lisa 2/5 shows boot ROM code H and I/O ROM code A8 in the upper right corner of the screen after the start-up icons; with the Screen Modification Kit fitted it shows 3A and A8.[3] Error code 51, "Parallel port VIA", sends the technician to the I/O board first, then the CPU board and motherboard; codes 80-85 are ProFile errors.[3] The full start-up sequence and error table are on Apple Lisa 2 and Apple Lisa.

In Apple's video repair table, "power supply trips (turns off and on)" lists brightness and contrast adjustment before replacing the supply; "a sizzling noise coming from Lisa" lists replacing the supply first.[3]
