The Atari 1010 Program Recorder is the cassette data recorder Atari introduced in December 1982 alongside the 1200XL, styled to match the XL computers. It shipped in spring 1983.[1] It stores programs and data at 600 bit/s on ordinary audio cassettes, using one track for data and the other for an audio track that a program can play through the television while it loads.[1]
Versions
[edit | edit source]Atari built two versions with different mechanisms and boards. Its field service manual calls them the 1010S and the 1010C.[3]
| 1010S | 1010C | |
|---|---|---|
| Mechanism maker | Sanyo | Chelco |
| FCC ID prefix (on the base) | BPA99H-1010 | BPA7YJ-1010 |
| Button order, left to right | PAUSE before STOP/EJ | STOP/EJ before PAUSE |
| Sticker inside the cassette bay | Orange | Silver |
| Data circuit | LA3160 (IC1) and MB3614 (IC2) | LM324 quad op-amp (A100) and discrete transistors |
The FCC prefixes, button order and data circuits are from Atari's manual;[3] the sticker colours are from Wikipedia;[2] the makers' names are from the FAQ.[1] Owners on AtariAge describe the Sanyo version as Japanese-built and the Chelco version as built in Hong Kong.[4]
Specifications
[edit | edit source]- Data rate: 600 bit/s.[1]
- Capacity: about 100,000 bytes per 60-minute cassette.[1]
- Tracks: four-track, two-channel, with digital data on one channel and audio on the other.[1]
- Data encoding: frequency-shift keying between 3995 Hz and 5327 Hz.[3]
- Connectors: two SIO I/O connectors, so the recorder can sit anywhere in the daisy chain, and a POWER IN jack for the adaptor.[1][5]
- Controls: REC, PLAY, REWIND, ADVANCE, STOP/EJ and PAUSE keys, a counter reset button and a power light.[5]
Hardware
[edit | edit source]Both versions take 9 V AC from an external adaptor and rectify it with a bridge on the board. On early units the power LED lights as soon as the adaptor is plugged in; on later units it lights only after PLAY, REWIND or ADVANCE is pressed.[3]
The computer starts and stops the tape through the motor control line, SIO pin 8. On the 1010C it drives Q107 and Q108, and a switch on the mechanism closes when PLAY, ADVANCE or REWIND is pressed. The 1010C's data circuit takes its +5 V from the computer.[3]
The 1010S records with maximum current at 5327 Hz; C10 tunes the record/play head to a peak near 5.5 kHz, and the limiter equalises the 3995 Hz and 5327 Hz tones before two envelope detectors and a low-pass output stage turn them into data at 600 baud.[3] In the 1010C, an LM324 limiting amplifier (A100A) feeds two active filters (A100B and A100C), whose rectified outputs drive a comparator (A100D); Q103 then drives the data line to the computer.[3]
Power adaptor
[edit | edit source]The FAQ lists the 1010's North American adaptor as 9 V AC, 4.5 VA (500 mA), Atari CO61515 or CO61516, and the UK version as 8.5 V AC, 4.25 VA, CO61516/34. The larger 9 V AC adaptors sold with the 400, 800 and 1050 also suit it.[1] Atari's service manual parts lists name C017945, the 31 VA adaptor, for both versions.[3]
Known faults
[edit | edit source]- Stretched or perished drive and counter belts.[4]
- Head out of alignment or worn; many of Atari's flowcharts end in a new head.[3][4]
- Motor speed drift, set by a trimmer on the 1010S and a screw inside the motor on the 1010C.[3]
- Loading errors 138 and 143 when the tape leader is read as data.[5]
The fixes are on the Atari 1010 Maintenance Guide and the Atari 1010 Troubleshooting page.
