TIIB LISA: A CASEHISTORY •PATRICIA DINES HE LISA: A CASE HISTORY by' Patricia Dines. ll.n January;.1983; Steve Jobs and John Sculley declared that Apple "~as betting the future of the company" on their new Lisa. Jn May, 1985, the mother Lisa was put to pasture, as the Mac carried on the flame. What happefied in this two and one~haljyears? And what is to become of those who believed and bought the computer? Settle down, dear reader, lo hear a most interesting tale about the computer called the Lisa. · I -:·:· 1111 :Ill price :?f: ,~,a Applo belttightening . I I ,,,,. (~ ~ 0 January 19$3: The New Baby In January of 1983, after four years of work, Apple released the baby Lisa to the world..At $9,995, this new personal computer paradigm includ~ one megabyte of internal memory, a five megabyte hard diSk drive, two 5-1/4" disk drives; and six core software programs: LisaWrite to write, LisaDraw to illustrate, LisaCalc to calculate, LisaGraph to show those numbers to others, LisaList to store and sort information, and LisaProject to · map the journey. ;All integrated; Moreover, Lisa (an acronym for "Local Integrated Software Archi~ture") was the first personal com,puter to use; a 10 mouse, and its graphic interface, reminiscent of the Xerox Star, was deemed revolutionary in its price range. And it was the first major PC to have within its "command center" a 32-bit microchip (the MC68000), the same chip now used in the Mac. Because this chip could carry twice the load of the then-current 16-bit chip, it could carry the baggage of the now-famous "userfriendly interface." After four years of work (200 person-years) and $50 million of investment, the thoughts at Apple must have included: Would they like it? Would they see its power? Would they•buy enough? Well, two out of three isn't bad. The Lisdl'alk Report• Winter Issue 1985 THE LISA: A CASE HISTORY •PATRICIA DINES (1) Hey, Mikey ~ they liked it! In March, 1983, John Eckhouse commented, "Consumer interest [in the Lisa] remains high, as evidenced by the tremendous crowds that have gathered around Lisa at the few recent trade shows where it has been exhibited." Many a user saw for the first time a computer such as they had only imagined - one they actually felt excited about using. In the six months after the introduction, Apple's stock rose from 33-5/8 to 62-5/8. (2) And - they saw its power. "The arrival of the Lisa has revealed a new dimension in the processing of research data," said Apple User magazine. Said D. R. Goodman of the Bay City Business Journal, "Apple's Lisa featured advanced 'software integration'; but more important, Lisa was innovative in 'demystifying' the technology. Apple promised to make computing ·accessible to ordinary people, no matter how technologically naive - an advance that was expected to revolutionalize the industry." "family" of 32-bit computers, seeming to add stability to the . prospects of the Lisa. Yet even then Mac's name was starting to surface. B…

To de-serialize 7/7 Applications: Clear byte 42 (hex) in each Tool directory entry. (Tools are named {T 1}0bj, {T2}obj, etc.) fuse FEdit.. These directory entries follow a condensed directory which just list file names. These are one sector per tool, with the desk-top name later in the bottom half of the sector. As you can see, LisaWrite is should be on sector 45 (2D hex).

These tests are done~ ln the Boot ROM and are· to ver1 fy that the correct data was progranmed into eacn1 ROM and that each ROM location is readable. This test calculates the checksum of each ROM, using the sarne method as the Lisa 1. o Boot RON,, and verifies that ectch ROH is correct. 1. For RON ltl. This ROM is the'one tnat contains the Startup and Diagnostic code. If this ROM is bad then a Boot ROM fatal error will occur right away. 2. For ROH #2. This ROH contains :nardware drivers and o. s. routines. If this ROH is bad then a fatal error will. occur after an other diagnosqcs have been run. viaeo MeRDry tests.· . I These tests assure~ that the sc;reen area and the data area ·for the A failure here is fatal ancJ will terminate testing . diagnostics are functioning properly. 1. stuck-at test~~~ veriffes that there ar.e no stucK-at-one or stuck-at-zero ireroory locations. 2. Address uniqueness test, verifies that eacn me100ry location is unique atld that no addresses are tied together. . 3. Meroory pattern tests, these tests looK for. ·other types of memory failures such as refreSh ·rails. , · 1 Extensive. These te~>ts are done in,the Boot ROH .. The Boot ROM uses tne video ·. memory as a data s~orage CleVice and .opetation entirely from the CPU board; with no nEroory board plugged 111, is essential for bOoting any device. · Burn-in and 178.rd tel rind problems. This ts. a set of extended meroory tests designed to be run from LisaTest. These tests run 'new and irrproved' pattern tests and are designed to catch very hard to find. memory errors. These tests may run from only minutes, to ·hOurs, or days. The only way for these tests to be accessiable are for the B1Jbt ROM• sown tests to have passed. · . ' .• _ V1de0c1rcu1try tests. This is a basic test of the Video circuit .. Both screen modes are timed to assure that the video is switching properly . 1. VRT /VID/CSVNC test. The hardware provides a two bits in the: status register which allows a program ta iooni tor the video signals :generated by the CPU board. This program tries to determine whether the CPU board video circuitry is working by looking at the VID ano CSVNC releat1onships. · The test checks ti:> see that the:re are transitions an the VRT (Vertical Retrace) bit in .the status register, and makes a rough extimate of the tirre between pulses on this signal . The CSVNC bit is tested for tran$1t1ons and tne VID bit is checked to make sure it is static for a solid black screen. The nufft)er of CSVNC pulses between vertical retraces is che~cKed. The third routit'.le 'first writes an al ternat1ng pattern of ls ano Os to the screen rrerory area, 45 words of then 45 words of 1, etc., until the area is filled. This will create a pattern on the screen of alternate white and blanK lines.…
