Atari 800XL Service Manual: Difference between revisions

Line 1:

The '''Service Manual for the ATARI 800XL Computer''' is published by '''Electronic Dimensions''', Post Office Box 1846, San Luis Obispo, California 93406, USA. 41 pages. '''The scan has no text layer.'''

'''This is not an Atari publication.''' Its own copyright page states that "Atari and 800XL are registered trademarks of Atari, Inc." and that reproduction is prohibited — it is a third-party service manual for the [[Atari 800XL]], and should be cited as Electronic Dimensions, not as Atari. That said, '''its parts list uses Atari's own part numbers''' throughout, so the data in it derives from Atari documentation.

== Contents ==

* '''Section 1 — Theory of operation''': user interface; mechanical theory; electrical theory; then device by device — 6502C CPU, ANTIC, GTIA, POKEY, PIA, memory (ROMs and DRAMs), '''MMU''', operating system ROM, RF modulator, monitor output, '''power supply''' — followed by the system interfaces: SIO, controller jacks, '''parallel bus interface (PBI)''', cartridge interface and keyboard interface

* '''Section 2 — Self testing''': overview, equipment needed, self-test features, and descriptions of the memory test, audio/visual test, keyboard test and all-tests mode

* '''Section 3 — Disassembly/assembly''' — 25

* '''Section 4 — Troubleshooting''': a guide to aid in the rapid diagnosis of problems — 26

* '''Section 5 — Schematic and parts list''' — 27, with the '''parts list from page 31'''

== What it settles ==

The parts list is laid out as '''location / device / Atari part number''' and covers the console assembly, the PCB assembly and every designator on the main board: capacitors C1–C112, diodes CR1–CR5, connectors J1–J8, inductors L1–L10, the ICs U6–U30 with their sockets, and '''crystal Y1 at 3.579545 MHz'''. Positions Atari did not stuff are marked "(not used)", which is why the numbering has gaps.

Its most useful single contribution is that '''the 800XL has very few electrolytic capacitors''', and this document names all of them. Read from the parts list pages:

{| class="wikitable styled-table" style="width:80%;"

| '''C98''' || Cap. Elec. Alum 10 µF (16 V) || C014371

|}

Every other capacitor in the list — the overwhelming majority — is an axial ceramic at 3.9 pF, 68 pF, 100 pF, 220 pF, .001 µF, .01 µF, .047 µF or .1 µF. A "full recap" of an 800XL therefore means replacing the ten parts above, not the whole board.

Other details from the list: '''A1 is the domestic modulator, a UM1652''' (Atari part CA061619); the keyboard is C061983; the TV switch box is CA014746 and the RF cable CA024624-001.

== What this manual does not contain ==

* '''No power supply internals.''' The parts list carries the supply as one line — Atari part '''CA024814-001''' — and §1's power supply discussion describes what the board receives, not what is inside the external brick. '''The 800XL's regulator is in the power supply, not on the board''', and no component-level data for it is published here or anywhere else on this wiki.

* '''No text layer''', so the parts list cannot be searched.

* '''No coverage of the 600XL, 1200XL, 800XE or the XE range''', and nothing on the 400 or 800.

* '''No component location map or silkscreen''' — the schematic is in section 5, but there is no board plan.

* '''No disk drive, printer or peripheral coverage.'''

* Being a third-party publication, it carries no Atari revision number and no service bulletins.
