Atari 1050 Documentation
The Atari 1050 documentation below comprises Atari's field service manual for the Atari 1050 disk drive, Howard W. Sams & Co.'s Computerfacts service data for it, and Atari's owner's guide.
Atari 1050 Disk Drive Field Service Manual
[edit | edit source]The 1050 Disk Drive Field Service Manual is Atari's service manual for the drive, part number FD100330. A separate scan of the Rev. 03 edition, dated October 1985, carries that part number on its cover.[1] The copy hosted here is a 77-page rebuilt scan without the cover, with the original schematic sheets and cleaner redrawn copies of them; its contents and page numbers match the Rev. 03 scan, which lacks many pages of sections 1 to 3.[2]
Contents
[edit | edit source]| Section | Title | Pages |
|---|---|---|
| Introduction | v | |
| 1 | Theory of operation: front and back panels, mechanical theory (case, drive mechanism, head carriage, drive and stepper motors), power supply and power-up logic, electronics theory (clock, 6507, ROM, RAM, 6532, 2793, write/erase, write protect and read logic, heads), serial bus line assignments, electrical specification and protocol | 1-1 to 1-21 |
| 2 | Test equipment and diagnostic tests: equipment, hook-up, mechanical checks, power-up test, diagnostic diskette, speed calibration, alignment tests, burn-in, error printout, track zero sensor calibration | 2-1 to 2-11 |
| 3 | Disassembly and assembly, including plug polarity (figure 3-1) | 3-1 to 3-2 |
| 4 | Symptom checklist, then signal waveforms for the motor, tachometer, stepper, diskette enable, track 00, read, write, erase, clock, write protect, power supply and data lines | 4-1 to 4-17 |
| 5 | Drawings and parts list: schematics (Tandon, four sheets), silkscreen, 1050 parts list (Tandon) | 5-1 to 5-11 |
| 6 | Appendix 6A, 1050 specifications | 6A-1 to 6A-3 |
| 7 | Service bulletins: Tech Tip 21, 30 September 1983 (ROM revision E or F) |
What this manual does not contain
[edit | edit source]- Capacitor values in the parts list. The list gives mechanical assemblies, semiconductors, inductors, the trimmers and the variable capacitor; capacitor values and ratings appear only on the four schematic sheets.
- Parts for the World Storage Technology mechanism. The parts list and schematics are for the Tandon TM50-1 version.
- A head azimuth adjustment. Atari replaces the mechanism if azimuth is out of specification.
- Any lubrication procedure.

Sams Computerfacts CD13, Atari Model 1050 Disk Drive
[edit | edit source]Computerfacts CD13 is Howard W. Sams & Co.'s technical service data for the 1050, dated February 1987, 22 pages including a fold-out schematic and an enclosed set of preliminary service checks.[3]
Contents
[edit | edit source]From the index (printed page numbers): schematic, 2; main board photographs, 3, 4, 13 and 14; grid location guide for the main board, 5; test equipment and troubleshooting, 6; parts list, 7 to 9; logic chart, 10 and 11; line definitions and schematic notes, 11; chassis top view, 12; IC pinouts and terminal guides, 16 and 17; general operating instructions, 17. The enclosed preliminary service checks (pages i to viii) cover disassembly, a numbered list of service checks keyed to photographs, and general preventive maintenance.[3]
What this document does not contain
[edit | edit source]- Voltage ratings for most electrolytic capacitors. The parts list rates only C2 (0.68 µF 35 V) and C41 (4.7 µF 16 V); the schematic gives values only.
- Atari part numbers. Sams lists replacement parts by description and gives no Atari numbers.

Atari 1050 Disk Drive Owner's Guide
[edit | edit source]The Atari 1050 Disk Drive Owner's Guide (Atari, 1982) is the 8-page guide packed with the drive. It covers connecting the drive and its adaptor, daisy-chaining up to four drives, the drive select switches, the DOS manuals supplied with the drive and the care of diskettes. It contains no specifications and no service information.
