Apple //e : “Early PAL”

I was looking for suitable Apple //e with atleast: case, lid, bottompan and keyboard for the Apple //e->IIgs upgrade project.. and this one was offered to me and the first pictures looked that it was really reasonably clean and nice non enhanced //e. Perfect candidate for the hack!

received_the_early_e_s
After receiving more pictures of it, it was clearly notiseable that it was “early model” with similar case used with Apple II/II+’s, that is totally different material and the good thing with it is that it doesn’t yellow. So no retr0bright process is needed. I had one of these early //e’s before but that was North American NTSC model. I never had or seen these early PAL models before so i got more interested. I actually never thought there were this “early” PAL model been manufactured in Europe but when you think of it surely they must have. I don’t know why but it had flied under my radar the whole matter. Glad to realize and learn new things.

I received the unit after a week and cleaned it up, took closer look of it and did some repair work as it was needed to get it running.

THE CASE:

compare_cases_s
Early model vs. later //e cases.

compare_cases_top_s
from top.

compare_cases_sideways_s
from side

 

compare_cases_back_s
from backside

date_on_case_s
These painted II+ styled cases are nice as they do not yellow. So it was easy to just put the unit in parts and washed the case, the lid and the bottompan. Notised it had stamped date inside of the case when it was made: “JUN 30 1982”.

serial_number_bottompan_s2
Serial label from the bottompan. Not the missing A2S2064 T – model number as it appeared soon after. Also the label had it’s own code 825-0472-A.

THE MOTHERBOARD:

removing_rust_fiberglass_pen_s
There were quite a bit rust on the screws that held the case and the motherboard in the basepan. I used some Coca-Cola to remove the rust, it worked somehow. Also the connectors on back were quite rusty a well, specially the paddle/joystick port and video output. The fiberglass pen is good tool for removing surface rust so i used that (it’s good idea to use respirator).

cleaning_the_rust_s
The result was quite good actually.

board_codes_s
The board revision : 820-0073-A | B-607-0664 (C) 1982.

colorkiller_modification_s
That had Color killer switch soldered to vacant oscillator position on PCB. All chips are socketed. I had never seen this early version before.

serial_number_board_s
The date on it was “1083” (10th week of 1983, March 7-13,1983). 

board_dates_s
..and stamped date of “R8308” so it’s even earlier than what’s those dates would indicate at wiki, if they mean the week they started to implement those changes?

board_closeup_s
There’s also a signature and some number where the an another label with numbers should be.

wiki:
Early : week 26 1983: 820-0073-A (c) 1982 / B-607-0664 Color killer switch soldered to vacant oscillator position on PCB. 
Normal : week 38 1983: 820-0073-B (c) 1982 / B-607-0264 Color killer switch near RHS of PCB. All chips socketed. 
65C02 : week 07 1985: 820-0073   (c) 1984 / B-607-0264 PCB marked for enhanced ROMs & 65C02 (may have old ROMs and 6502). RAM & some TTL soldered in. Layout same as above. 

week 38 1983: 820-0073-B (c) 1982 / B-607-0264 Color killer switch near RHS of PCB. All chips socketed.
-I have few of these revisions but mine doesn’t have ALL chips socketed. Only few sockets.

There were also the Platinum model made in Ireland with “International NTSC”-board on it (these are from my collection):

Platinum : week ?? 1986: 820-0188-C (c) 1986 / 607-0288-C / 8653
Platinum : week ?? 1988: 820-0188-E (c) 1986/87 607-0288-D / 8820
Platinum : week ?? 1988: 820-0188-E (c) 1986/87  / S-607-288-D / 8809

There isn’t any information actually, WHEN, they started the production of the Apple //e in Ireland. This would be really interesting to know. What day/week in 1983 ?

Fixing and diagnostics the board:

white_bars_at_beginning_s2
Some repairing was needed as it would not power up without giving vertical white bars on screen at first. I swapped first chip-by-chip starting from CPU, IOU and MMU but it didn’t make any difference.

random_chars_at_screen_1_s2
Next i swapped the EF-ROM chip (to date code: “8325”) and i got rid of the vertical bars but got screen full of random characters instead. That would usually indicate the board having issue with the RAM chips but i could not figure out what chip at what location was actually bad so i installed the “Apple //e Diagnostic card” and fired that away.

testing_with_diagnostic_card_s
Apple //e Diagnostic card:

error_at_f09_s
It showed that it had error at board location: F09, that’s RAM chip location, so i replaced that.  It’s nice to have such board with all chips socketed.. but no change!  Ah!.. it assumes the NTSC board layout?! I compared to NTSC and PAL board chip locations and realized: F09 = F06 in PAL board. Tried again and got error in board location F12. There’s NO RAM in F12 location in PAL board but comparing the NTSC board again, F12 = F09 in PAL board. I got an another RAM chip and swapped that and everything worked fine.

PROCESSOR:

The main processor was supposed to be regular 6502 but it was clearly replaced with R65C02P3 (450-13 8439). Swapped this to regular 6502 from date code “8309” so it was period perfect fit for the manufacturing date era.

ROM-CHIPS:

rom_chips_s

The Keyboard ROM : 341-0152 REV.A Apple 82 (eprom)
Video ROM : 341-0162 REV.B Apple 82 (eprom)
EF ROM : 342-0134-A Apple 82 ( > swapped to 342-0134-A “8325” Apple 1982)
CD ROM : 342-0135-A Apple 82 “8313”

So all look period perfect for this unit been made in early 1983. If i’d aim for more accuracy i would swap the EF-ROM “8325” bit earlier one from 1983 but that was what i had available.

THE KEYBOARD:

Few of the switches got easily stuck so i cleaned it with electronics cleaner spray and tried to twiggle and press repeatly the switches to get them working. The keyboard was the regular //e keyboard and there is the switch underneath the case for switching the character sets. What made me wonder, when the //e was released they used different keyboard in the beginning, atleast in North America. That keyboard had white letters and looked quite different to this common, later model. I have not however seen any early PAL model keyboards so i am not certain if there were this earlier style keyboard used in Ireland. 

keyboard_pcb_differences_s
The keyboard PCB was clearly different than the later one. The traces were much thinner. Maybe just different keyboard manufacturer.

keyboard_diagnose_errors_s
After cleaning it up i tested the keyboard. The keys “7” and “Open Apple” had issues even all traces seem to be OK – checked that with multimeter. The “7” occationally get’s stuck so hopefully more cleaning and pressing the switch will resolve that matter but for the “Open Apple”, it was all dead. So i swapped the switch (luckily i had one spare left) for it and it worked.

The Keyboard ROM : 341-0152 (REV.A Apple 82) did give me correct versions, Swedish/Finnish and English characters when flipped the switch underneath the keyboard. That was nice it was all original and working.

 

THE POWERSUPPLY:

psu_original_s
The powersupply was the regular, short, gold colored, Astec AA 11040C, 230v 50Hz 0.5 Amp model. Opened it and it looked clean and no caps leaking or bulging. I made the initial testing first with good known recapped //e (longer model) powersupply and tested the original one later. I should have either recapped it or removed the RIFA’s from it.. but this ones goes to collection not for daily use.

DETAILS:
(i like details collected, so this is mainly for safekeeping this information)

Case serial : A2AS2-100190 (Assembled in Ireland)
Case date : JUN 30 1982
Powersupply : Astec AA 11040C, 230v 50Hz 0.5 Amp
Board code : 820-0073-A | B-607-0664 (C) 1982
Board date code : 1083
Keyboard ROM : 341-0152 (REV.A Apple 82)
Video ROM : 341-0162 (REV.B Apple 82)
EF ROM : 342-0134-A (Apple 82) > broken > swapped to 342-0134-A “8325” Apple 1982
CD ROM : 342-0135-A (Apple 82) “8313”
CPU : R65C02P3 (450-13 “8439”)  (>swapped to 6502 “8309”)

Cards : 
-Disk II card (Apple, Made in Ireland)
-Apple //e 80col-64k card (Apple 1985, 607-0103-I)
-Printer Interface card (Taiwanese clone)

80col64kcard_earlier_revision_s
I swapped in an earlier model of the 64k/80-col card : 607-0103-I/820-0067-C (1985) to 607-0103-E/820-0067-B (1981) so it looks more period perfect.

case_early_3_s
All done.

What about my “//e->IIgs upgrade hack project” then? .. looks like this is all too good unit to be sacrificed for the IIe>IIgs upgrade hack project so it goes to my collection directly.. so need to find an another //e for this.
