(Worldwide overseas shipping:   .00]
147 happy buyers can't be wrong.
No price inflation; same .00 price since 2007!
SPECIAL QUANTITY DISCOUNTS
Buy  THREE for .00 plus  .65  total USA shipping   (.00 each)
Buy TEN for .00 plus .65  total USA shipping  (.00 each)
It enables use of the rare white-cased Unidisk 3.5 drive!
The is a 28-pin custom ROM chip for the classic Apple IIC.
It resembles the Apple brand enhanced ROM # 342-0033.
Inside the IIC, the older  UNENHANCED ROM is # 342-0277.
The Enhanced ROM chip adds these features to your IIC:
(1)  Capability to operate the Unidisk 3.5" 800K external disk drive.
(2) The checkerboard self-test: Hold down the two Apple-keys at power-
up;
If enhanced, you will see a moving checkerboard pattern which
ends with, "SYSTEM OK." The self-test will identify any specific
RAM memory chip
that has gone bad.  Other deficiencies are also
identified. The
checkerboard self-test is shown in the fourth photo.
If you
presently
can get the checkerboard self-test  with your IIc, then
your computer is already enhanced and my ROM chip is not needed.
(3) A customized brief one-two word message at the center-top
of the opening screen. This message is displayed for three
seconds every time when the Apple IIc is powered up.
A two-sided instruction sheet to install the chip is included.
Essentially,
you just replace the existing 28-pin ROM chip
with this chip, then make two minor soldered changes
on the IIC motherboard.
A photocopy will be enclosed of Otto Linzmeyer's article in the
January 1988 issue of A+ magazine,
"
THE APPLE IIC FAMILY TREE
,"
which describes firmware/hardware differences among
the three distinct versions of Apple IIC that were released
(1984-1988).  Also enclosed will be a photocopied section from the
Apple IIc Technical Reference Manual
(1985) that describes
the Unidisk 3.5 ROM code that is contained in this chip.
The Apple IIC Plus differs totally from the three earlier IIc models.
If you bought a IIc CPU from me, then its ROM is already enhanced.
Made in USA
"PRINT PEEK" ROM TEST:
"0" ON THE SCREEN
The enclosed article, "IIc Family Tree,"
presents a keyboard test to identify
which ROM version your IIc presently
has.  First, turn on the computer. Then
press CONTROL followed by RESET. The
Basic prompt, a left-facing bracket  ]
will be displayed on the screen. Next,
type:
PRINT PEEK (64447)
followed
by RETURN. The computer's response
identifies which Apple //c you have:
255     Original (unenhanced) //c
0       Unidisk 3.5 //c
3 or 4    Memory-Expansion //c
Installing the ROM chip purchased from
this ad will upgrade your //c from the Original
version to the Unidisk 3.5 version.  It is impractical
to become a Memory-Expansion //c because the
two earlier versions lack the motherboard socket
for the one meg Ram Express memory board.
NEWS FLASH:  December 23, 2020
A IIc user who bought the ROM 0 enhanced
ROM chip from me, reported that this chip
enables the Apple IIc to operate a 32meg
hard drive, connected to the IIc at the DB-19
external floppy drive socket.  Can someone
check this for me?  I suggested to the buyer who
reported this, to prepare a KansasFest presentation
on it.  Many Apple IIc users would be enthused
to confirm that the IIc can operate an external
hard drive!
REFUND GUARANTEE  FOR
USA BUYERS AND ALSO  FOR
WORLDWIDE OVERSEAS BUYERS
The IIc ROMs are all guaranteed to work!  About
147 these ROM chips have already been sold.
All are pre-tested prior to shipping, and I
have had no complaints, so far, from buyers.
CHOICE OF SCREEN-OPENER MESSAGES
This ROM-encoded nine-character message appears at
the top of the screen when power is first turned on.
Either the standard IIc enhancement message:
Apple  //c
or this alternative message:
( New!    April 2020 ):
Canada
or this alternative message:
Enhanced!
or this alternative message:
KFEST  //c
or this alternative message:
Woz  //c
or this alternative message:
3.5" Disk
or this alternative message:
Obama  //c
or this alternative message:
Gallup NM
or this alternative message:
Bugg //c
HHHHHHHHHHHHHHHHHHHHH
Send me an Ebay message to indicate
your preference.
If no preference is stated,
then the opener message
on your ROM
chip will be the
Enhanced!
version.
TWO EPROM BURNERS
PRODUCE THE ROMs
An Apple IIe interface card,
THE SUPER EPROM MASTER,
creates the original master ROM chip.  Then, duplication
of the master chip is done with
GANGPRO-8,
made in
USA by Logical Systems Corp. of Denver CO. The
GANGPRO-8
makes perfect ROM chips every time.
SPECIAL DISCOUNT UNTIL
JULY 2, 2021
FOR THE CANADIAN
APPLE IIc ENHANCED ROM CHIP: TWO
IIc CANADA ROMS .00 + S/H
My Irish ancestors lived at New Brunswick Canada,
1850 to 1900; Then they left Canada and resettled
to Minnesota.  The enhanced opening screen message,
CANADA, at the top of the opening IIc screen, is now
available at half price:
Two Canada IIc enhanced ROMs
for .00 plus shipping.
This Canada IIc ROM special
expires after July 1, 2021, Canada's National Day
(Fete du Canada).
SHIPPING COST: ONLY
THE ACTUAL POSTAGE!
Some Ebay sellers conceal the actual postage
cost; I have the software print the postage cost
at the top of the shipping label.  If the actual
postage cost is {{detail_product_description}}.20 or more below what you
paid, I will refund the amount overpaid to your
Ebay account, as soon as the package is mailed.
QUANTITY SOLD:  ADD 95 TO NUMBER
STATED AT HEADING OF THIS AD
I sold 95 of these IIc ROM chips in the first four years.
But I completely sold out of my first batch, so
Ebay then reset my quantity number to zero.
So, my total number sold is 95 plus the
total stated at the heading of the ad.
USA shipping is .65.
The shipping cost covers the ROM, the articles and other
printed matter, and the enclosed diagnostic disks.
Shipping is WORLDWIDE.  Shipping will be via post office first class mail.

PRESERVING  FIRMWARE ON EPROMS:
A KEY TO "APPLE II FOREVER"

ABSTRACT
Most computer equipment contain EPROMs in their circuits:
CPUs, printers, interface cards, or peripherals.
The EPROM
chips contain firmware code to control
operation of the
device. An EPROM looks like a
large IC chip: It is wide, with
24 to 40 pins. There is a
small round window in the center of
the upper side of the chip, with a microlattice of fine metal
wires visible through the clear quartz-glass window.
The
EPROM chips can be erased and reconfigured by hours of
exposure to ultraviolet light, followed by software-controlled
"burning" of fresh code. The use
of EPROMs allows the periodic
upgrading of firmware.  In my
presentation, EPROMs and
related hardware will be shown and discussed. Knowledge
about EPROM technology should be shared
among Apple II
devotees because the EPROMS can go bad after years of service.
The firmware code
can be stored on floppy disks, and then
used to rejuvenate EPROMs that have gone bad. In the long
run, spanning future decades, Apple II equipment will survive only
if the firmware code on the
EPROMs has been preserved on disks;
once on disk, the code
on could be preserved for
indefinite archiving
by recopying it to other long-lasting media such as CD-ROMs or
flash drives.
Apple II users should learn EPROM-burning skills,
with the needed hardware, to
create fresh copies of the firmware
code for themselves and to be shared widely with others.

AVAILABLE NOW IN A
SEPARATE EBAY AD:
APPLE IIC BATTERY-
PORTABILITY KIT
Go to Ebay ad
# 221447214363
221447214363
The 16 ft. cord uses top quality wire:
American-made red/black insulated
stranded pure copper
AWG-16 wire
with DIN-7 female plug at one end,
and 12v cigarette
male plug (with LED and on-off push-button switch) at the other end.
Includes wires and connectors to operate your Apple IIc outdoors, off-the-
AC-power-grid!  Do Apple II computing at the beach, on a mountain top,
or at any campground, even when the campground has no AC 115v outlets!
Use your Apple IIc with a car battery from the cigarette-lighter socket,
_or_
with a jump-start DC 12v battery, _or_ with alligator clips directly from the 12v
battery terminals.  You will need to get a 12v color flat screen TV to use with your
Apple IIc, new on Ebay from 0.00.   My .00 battery portability kit supplies all
the rest!  This kit was demonstrated to Apple II experts at KansasFest, July 2014.
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
INTERNATIONAL: SALES
TO OTHER COUNTRIES
I will ship to other countries.
I retain the post office receipt as proof of mailing.
International mails in recent years have become very reliable, so I will replace
any ROM chip lost during shipping.  Buyers have told me that Ebay's "Global
Shipping Program" (GSP) is very expensive for small lightweight packages
such as this ROM chip, or for small keyboard parts such as keyswitches
or keycaps,
so international first class mailing is preferred;  even then,
U.S. postage rates
begin at .00 for most foreign countries beyond
Canada.
In mid-2020,  Ebay has launched a special international
shipping service, by which the seller ships to a trans-shipment
service in CA or KY,  from which it is carried to the foreign destination.
Look at all my
items offered for
sale; combined shipping of two or
more items costs
only slightly more than shipping a single small item.
I must guess
at the weight / postage cost. I will guess
slightly high,
but will refund any excess amount
paid for postage,
to the buyer's
Ebay account,
immediately after
the item has been shipped.
