I came across a performa 636cd, (i know, under 10 yrs by far.) but this
is a more generic question. It has a 68LC040 processor; I need a straight
68040 for NetBSD... is it possible to nab one of these from someplace and
just put it in? besides any clock speed issues & whatnot, are they all the
same "under the hood" ? or are they all different. I guess this applies to
several other systems I have, since I'm interested in upgrading other things
as well. any info appreciated. thanks!

Hello, all:
I made another trip to Temple University yesterday to rummage through
their storehouse of old computers and documentation. I hate to post a list,
but I don't have a working web site yet, and I want everyone to know what I
have in case someone needs something.
Here it goes...
1. Mac Portable (no HD, bad batteries)
2. Many Unibus and Q-Bus boards
3. Odd DEC single-board computer. 10" x 7" labeled DEC 54-16489, Has two
84-pin PLCC chips
with the LSI LIA 0433 and 0434 marks. Has a DB25, DB15, and DB9.
Recognizable chips
include 8051, FD1796, CDP 6402 (RCA), and D7201C (NEC) Can anyone
identify this?
4. Three Motorola 68K educational computers. Has 32k RAM, 68K, 6850,
14411 chips and a
proto area. Also has two EPROMs. Any guess?
5. Three KIM-1s!! (There are one or two more left, too). Two are
MOS-labeled, one is *brand new* from
Conversational Voice Terminal Corp. of Chicago. Need data on this
one. The MOS-labeled ones
have 1976-dated ceramic chips.
6. A S-100 backplane from Forethought Products. Has 8 slots, some glue
and regulator chips.
7. Lots of documentation. A sampling...
-- Intel: MCS80/85 User Guide (1983), Memory Handbook (83), Embedded
Controller Book (88), Component Data Book (80; looks to be full-line), OEM
Boards (87), 8080/85 Assembly Language Programming Manual, Applications
Note --implementing a floppy system (1981).
-- DEC: Logic handbook (77), Microcomputer Microprocessors (78)
-- Motorola: MC68020 User Man., MEK6800 Guide, 6809 Assembly
Language, 6800 Pgmr. Ref. Manual.
-- Full documentation set for the Rockwell AIM-65 computer (user
guide, BASIC language, Programmers Manual, Hardware Manual, Monitor Program
Listing).
-- Textbooks on microprocessors by Tocci & Laskowski, and Camp, Smay
& Triska
8. Old magazines. The guy who ran the CS department before the guy I know
saved everything. Byte's going back to 1978 (too many to get this trip),
Datamation, others that I never heard of. But, the jewel is that I came
*this* close to getting the Altair issue of Popular Electronics.
Unfortulately, this guy only had as far back as 1/76. Articles include:
Cosmal Elf construction articles, SOL construction, build a Scientific
Calculator, music with the 8080, TV Typewriter, SpeechLab, Computer Club
listings, a personal microwave communications system, various
Classic-relevant product reviews and buyer's guides.
9. DEC paper tapes: PDP-11 power fail, LPS11 tests, General Test Program,
RK05 dynamic test, RK11 utilities, exerciser, static tests.
10. Complete print sets for the following: PDP 11/34A (two copies,
complete), FP11, H960 cabinet, KSI-11, DLV-11, DL-11, H9720, ET-LSI-11,
LSI-11 power supply, MS11, PC11, LPS11, MR11, M873, KD11F, RK05 (regular, F,
and J).
My plan is to scan the articles, and have an on-line database hanging
off of a web site. I also want to implement a bar code system for my
goodies. That'll take a while, though.
Anyway, thanks for the bandwidth.

I hear Apple would give these away to dealers, salesman, and others. I
missed a newton on ebay that was clear also it went for close to $400 I think.

Hello, all:
Well, I began to clean up the spoils of my recent recovery mission, and
I'm having problems with the Mac Portable that I got.
Besides the hard drive and batteries being shot and the screen having a
small defect in it, I keep getting a Sad Mac code. It's code 0000000F with a
sub code of 00007FFF. I can't find a reference to the $0F code in any Sad
Mac code listings that I have (they skip over it, going from $0E to $10). I
get the code after inserting a known-working diskette. I've tried 400k disks
and 800k disks with the same results. I haven't tried a 1.44m disk yet,
since I don't have a recent Mac to create one. I've tried a 1.44m disk
created by HVFExplorer, but I get the "bad disk" message.
Also, there's a 4-position DIP switch on the mobo. What's this for? Any
ideas on the Sad Mac code?

the one I had had a ten meg winchester hard drive, that was some drive, I
think it was made of cast iron well, the case at any rate. It also had a
glass like cover ocovering up the iners of the harddrive.
The two 5.52 flopys wore 180 K and conected to the mother board.
It does slide out of the sleeve quite nicely, the two cards that are
conected togather are lan and mem ory combination, I think, when I removed
them I had less memory.
I found out why it wouldn't boot, it was a pin on the c p u didn't make it
in the hole, when some one tryed to plug it in, straitening the pin cracked
it off, ****! I thought about it for some time and used a peese of coper
wire to fix it, first I incerted the wire into the hole whear the broken pin
would have been once the chip was pluged in, I don't remember how I was able
to locate the hole, I don't have to tell you how tiny they are, the chip
still had a bit id the broken pin sticking out of the side of it, not enough
to solder , but enough to make a tite contact whith the coper wire, after
the chip was plugged back in I trimed itso it didn't stick up a half inchbut
just a little over the top of the chip.
It worked!
I can't remember if it booted in a wordprosesser or a menu, I think it was
a word prosessor.
I seem to remember some thing funy about the program was you couldn't quit
it , it would not let you I think it just rebooted, unless you had a flopy
in drive A:.
The not so funy thing about the monotor is the power and data cords
coming out of it both had the same plug on the end of them, and pluging the
data plug in to the power socket on the vidio card was a hasard.
Since they wore bothe the same kind of plug I tied a twist tie around the
power plug just to let me know whitch was whitch, just incase I got the ich
to use the monoter when I was writting stuff in the word prosesser.
Oh well, It was still is a great machine albeit huge!

Not entirely true. ESD does permanent damage to the device even if it
doesn't die. ALL (that I know of) drives have an internal air filter to
pick up any dust that may appear so if the media is not damaged the air will
be cleaned and reliability should be nominal (excludes the reason for first
opening it). I have several drives I've had to open all running and all
apparently living longer than average!

I have the feeling this is the early version, because mine is the later
backlit one, which has no dip switches. The sad mac code could very
easily be due to a power problem. It will sadmac if there isn't enough
power. Note that running off the portable AC adapter is _not_ enough.
You need an additional .5 amps, whereever you get it.
