Clock and Data Signals

Open

The keyboard and system communicate over the 'clock' and 'data' lines. The source of each of these lines is an open-collector device on the keyboard that allows either the keyboard or the system to force a line to an inactive (low) level. When no communication is occurring, the 'clock' line is at an active (high) level. The state of the 'data' line is held active(high) by the keyboard. When the system sends data to the keyboard, it forces the 'data' line to an inactive level and allows the 'clock' line to go to an active level. An inactive signal will have a value of at least 0, but not greater than +0.7 volts. A signal at the inactive level is a logical O. An active signal will have a value of at least +2.4, but not greater than +5.5 volts. A signal at the active level is a logical 1. Voltages are measured between a signal source and the dc network ground. The keyboard 'clock' line provides the clocking signals used to clock serial data to and from the keyboard. If the host system forces the 'clock' line to an inactive level, keyboard transmission is inhibited. When the keyboard sends data to, or receives data from the system, it generates the 'clock' signal to time the data. The system can prevent the keyboard from sending data by forcing the 'clock' line to an inactive level; the 'data' line may be active or inactive during this time. During the BAT, the keyboard allows the 'clock' and 'data' lines to go to an active level.

Data Stream

Data transmissions to and from the keyboard consist of an 11-bit data stream (Mode 2) sent serially over the 'data' line. A logical 1 is sent at an active (high) level. The following table shows the functions of the bits.

Bit Function
1 Start bit (always 0)
2 Data bit 0 (least-significant)
3 Data bit 1
4 Data bit 2
5 Data bit 3
6 Data bit 4
7 Data bit 5
8 Data bit 6
9 Data bit 7 (most-significant)
10 Parity bit (odd parity)
11 Stop bit (always 1)

The parity bit is either 1 or 0, and the 8 data bits, plus the parity bit, always have an odd number of 1 's.

Note: Mode 1 is a 9-bit data stream that does not have a parity bit or stop bit and the start bit is always 1.

Keyboard Data Output

When the keyboard is ready to send data, it first checks for a keyboard-inhibit or system request-to-send status on the 'clock' and 'data' lines. If the 'clock' line is inactive (low), data is stored in the keyboard buffer. If the 'clock' line is active (high) and the 'data' line is inactive (request-to-send), data is stored in the keyboard buffer, and the keyboard receives system data. If the 'clock' and 'data' lines are both active, the keyboard sends the 0 start bit, 8 data bits, the parity bit, and the stop bit. Data will be valid before the trailing edge and beyond the leading edge of the clock pulse. During transmission, the keyboard checks the 'clock' line for an active level at least every 60 milliseconds. If the system lowers the 'clock' line from an active level after the keyboard starts sending data, a condition known as line contention occurs, and the keyboard stops sending data. If line contention occurs before the leading edge of the 10th clock signal (parity bit), the keyboard buffer returns the 'clock' and 'data' lines to an active level. If contention does not occur by the 10th clock signal, the keyboard completes the transmission. Following line contention, the system mayor may not request the keyboard to resend the data. Following a transmission, the system can inhibit the keyboard until the system processes the input, or until it requests that a response be sent.

Keyboard Data Input

When the system is ready to send data to the keyboard, it first checks to see if the keyboard is sending data. If the keyboard is sending, but has not reached the 10th 'clock' signal, the system can override the keyboard output by forcing the keyboard 'clock' line to an inactive (low) level. If the keyboard transmission is beyond the 10th 'clock' signal, the system must receive the transmission. If the keyboard is not sending, or if the system elects to override the keyboard's output, the system forces the keyboard 'clock' line to an inactive level for more than 60 microseconds while preparing to send data. When the system is ready to send the start bit (the 'data' line will be inactive), it allows the 'clock' line to go to an active (high) level. The keyboard checks the state of the' clock' line at intervals of no more than 10 milliseconds. If a system request-to-send (RTS) is detected, the keyboard counts 11 bits. After the 10th bit, the keyboard checks for an active level on the 'data' line, and if the line is active, forces it inactive, and counts one more bit. This action signals the system that the keyboard has received its data. Upon receipt of this signal, the system returns to a ready state, in which it can accept keyboard output, or goes to the inhibited state until it is ready.

If the keyboard 'data' line is found at an inactive level following the 10th bit, a framing error has occurred, and the keyboard continues to count until the 'data' line becomes active. The keyboard then makes the 'data' line inactive and sends a Resend. Each system command or data transmission to the keyboard requires a response from the keyboard before the system can send its next output. The keyboard will respond within 20 milliseconds unless the system prevents keyboard output. If the keyboard response is invalid or has a parity error, the system sends the command or data again. However, the two byte commands require special handling. If hex F3 (Set Typematic Rate/Delay), hex F0 (Select Alternate Scan Codes), or hex ED (Set/Reset Mode Indicators) have been sent and acknowledged, and the value byte has been sent but the response is invalid or has a parity error, the system will resend both the command and the value byte.

Error handling

When keyboard response to command and data from host has parity or other error, Resend(FE) should net be sent.

If the keyboard response is invalid or has a parity error, the system sends the command or data again.

When host receives data with prirty error, host sends Resend(FE) command.

IBM 1390876

When sent an identify command (0xF2), the keyboard returns the byte sequence 0xBF 0xBF. However, this can be changed. On the keyboard PCB is a 12-pin header, marked as 6 pairs of pins (B2-B7). These correspond to bits 5-0 of the second byte of the keyboard ID. Shorting a pair of pins sets that bit to zero. So placing a jumper on the B2 pair will change the keyboard ID to 0xBF 0x9F.

Adjacent to this header is a space on the circuit board for an identical header, marked as pins A2-A7. Presumably these would have the same effect on the first byte of the keyboard ID.

http://www.seasip.info/VintagePC/ibm_1390876.html#Identity

IBM 6110344

DIP Switch: 0000 0000

The keyboard has eight DIP switches. According to the guide to operations, they should be ignored. If you do change them, they change bits in the keyboard ID (returned by command 0xF2). If all switches are left open (or disconnected) the ID returned is 0xBF 0xBF. Closing a switch sets the corresponding bit to 0.

Switches 1-6 correspond to bits 5-0 of the first ID byte. Switches 7-8 correspond to bits 5-4 of the second ID byte. The header on the controller PCB, to which the DIP switches are connected, has 12 pairs of pins and is silkscreened "KBDID A" (on the first 6 pairs) and "KBDID B" (on the second six). The other four pairs of pins correspond to bits 3-0 of the second ID byte; these would need to be set with jumpers.

Exceptional Key Handling

Microsoft Keyboard Scan Code Specification

/*******************************************************************************
 * AT, PS/2: Scan Code Set 2
 *
 * Exceptional Handling
 * --------------------
 * Some keys should be handled exceptionally. See [b].
 *
 * Scan codes are varied or prefix/postfix'd depending on modifier key state.
 *
 * 1) Insert, Delete, Home, End, PageUp, PageDown, Up, Down, Right, Left
 *     a) when Num Lock is off
 *     modifiers | make                      | break
 *     ----------+---------------------------+----------------------
 *     Ohter     |                    <make> | <break>
 *     LShift    | E0 F0 12           <make> | <break>  E0 12
 *     RShift    | E0 F0 59           <make> | <break>  E0 59
 *     L+RShift  | E0 F0 12  E0 F0 59 <make> | <break>  E0 59 E0 12
 *
 *     b) when Num Lock is on
 *     modifiers | make                      | break
 *     ----------+---------------------------+----------------------
 *     Other     | E0 12              <make> | <break>  E0 F0 12
 *     Shift'd   |                    <make> | <break>
 *
 *     Handling: These prefix/postfix codes are ignored.
 *
 *
 * 2) Keypad /
 *     modifiers | make                      | break
 *     ----------+---------------------------+----------------------
 *     Ohter     |                    E0 4A  | E0 F0 4A
 *     LShift    | E0 F0 12           E0 4A  | E0 F0 4A E0 12
 *     RShift    | E0 F0 59           E0 4A  | E0 F0 4A E0 59
 *     L+RShift  | E0 F0 12  E0 F0 59 E0 4A  | E0 F0 4A E0 59 E0 12
 *
 *     Handling: These prefix/postfix codes are ignored.
 *
 *
 * 3) PrintScreen
 *     modifiers | make         | break
 *     ----------+--------------+-----------------------------------
 *     Other     | E0 12  E0 7C | E0 F0 7C  E0 F0 12
 *     Shift'd   |        E0 7C | E0 F0 7C
 *     Control'd |        E0 7C | E0 F0 7C
 *     Alt'd     |           84 | F0 84
 *
 *     Handling: These prefix/postfix codes are ignored, and both scan codes
 *               'E0 7C' and 84 are seen as PrintScreen.
 *
 * 4) Pause
 *     modifiers | make(no break code)
 *     ----------+--------------------------------------------------
 *     Other     | E1 14 77 E1 F0 14 F0 77
 *     Control'd | E0 7E E0 F0 7E
 *
 *     Handling: Both code sequences are treated as a whole.
 *               And we need a ad hoc 'pseudo break code' hack to get the key off
 *               because it has no break code.
 *
 * Notes:
 * 'Hangul/English'(F1) and 'Hanja'(F2) have no break code. See [a].
 * These two Korean keys need exceptional handling and are not supported for now.
 *

System Request and Print Screen

The 'System Request' key(0x84) was introduced on IBM PC/AT 84-key and integrated into 'Print Screen' key later on Enhanced 101-key. Alt + 'Print Screen' generates scan code 0x84 on Enhanced keyboard.

IBM 5576 Scan Codes Set

The 5576 keyboard series supports special code sets.

The 5576 keyboads starts up with Code Set 2 which doesn't enable Japanese specific keys and emulates US layout. Code Set 2 is not useuful in fact. TMK IBMPC converter uses Code Set 3 for 5576-001 and Code Set 82h for 5576-002 and 5576-003. Resouces says 5576-001 doesn't support Code Set 1, 3 and 81h, though, 5576-001 can work with Code Set 3 actually.

5576-A01 is completely compatible to standard Japanese PS/2 keyboard.

Code Set Description
1 without Japanese specific key support
2 without Japanese specific key support
3 All keys can be used
81h Code Set 1 with Japanese specific key support
82h Code Set 2 with Japanese specific key support
8Ah IBM 5550 compatible

Special Key Combo

These key combos are interpreted as special function on PC/AT and PC/XT computer(BIOS).

  • Ctrl+Alt+Delete -> System Reset
  • Ctrl+NumLock -> Pause
  • Ctrl+ScrollLock -> Break
  • Shift+PrtSc/* -> Print Screen
  • Alt+PrtSc/* -> System Request?

TMK converter doesn't recognize the combos, interprets them just as normal key sequence.

Weirdness

SIEMENS PCD 2 Keyboard

The keyboard requires "inhibit" time after data communications for some reason. Without the "inhibit" the keboard repeats to send the last code endlessly. https://github.com/tmk/tmk_keyboard/issues/747

Incompatibilities of Zenith Z-150 AT

It seems that the keybaord came with Zenith Z-240 AT compatible computer.

This keyboard is sometimes referred as 'white badge' or 'beige' due to its enclosure and it's compatibility with AT protocol seems to be very bad. It works somewhat with some converter or PS/2 port on PC while not at all with others.

See wafeform above. It is obviously violation of IBM AT protocol signal.

TMK IBMPC Converter can support the keyboard including Lock indicators as of 2021-10.

Open

TMK IBMPC Converter

The converter can read scan code from the keyboard without stop bit check but it fails to send commands when lock indicator is updated. and can control LED indicators now(2021-06). See below.

Send command

Z-150 AT has start bit error(ERR:11) sometimes and requires some retries. Root cause of the error is unclear.

https://github.com/tmk/tmk_keyboard/commit/67d37ef7b312ccd40e8e82c0cb1444b36b3fbcd9

https://geekhack.org/index.php?topic=103648.msg3055134#msg3055134

Lock Indicators

It seems to accept 'ED' command from some computer, LEDs can be controlled normally from host. But TMK converter and most of PS/2 ports fails to send 'Set Indicator' commands.

The lock keys of a separate keyboard do indeed turn on the corresponding indicator LED of the Zenith when connected to the HP.

https://geekhack.org/index.php?topic=103648.msg2896728#msg2896728

Over native ps/2 the lock lights will similarly fail to register with rapid presses and causes a reset. The only difference I see compared to with the converter is that the board does a "softer reset" such that the beeper on/off state is not changed.

Monoprice PS/2 Converter

http://www.newegg.com/Product/Product.aspx?Item=9SIA8SV3807929

I have a beige-label, which is the AT model. It works fine with the linked PS/2 -> USB converter, after a DIN -> PS/2 converter as well of course. I can try to find the DIN -> PS/2 converter online if that matters, it looks very generic. The only issue I've run into is that the F7 key only works over PS/2, the USB converter seems to prevent that specific key from being sent (the internal buzzer still beeps when it is pressed, the PC just never recieves the code). I have tried a BlueCube and it doesn't work at all, strangely enough.

https://deskthority.net/viewtopic.php?p=293309#p293309

Another witness: Monprice converter works with the Z-150 but it doesn't control lock indicators and doesn't handle F7 key but others.

TMK PS/2 INT doesn't work

https://deskthority.net/viewtopic.php?p=297627#p297627

Doesn't work even with PS/2 port on PC

I tried using a very generic at to ps2 adapter then a blue cube and didn't have any luck. The keyboard lights up the first time you plug it in. Edit: I was messing with the adapters and if I go from at to ps2 into my ps2 port the keyboard works during post. Edit 2: It only works for a few moments during post. Eventually it stops beeping.

https://deskthority.net/viewtopic.php?p=353558#p353558

Some computers work but others not

It had perfect function on my: HP 8200/8300 Compaq SR1920nx (yeah, that's an oldie, my first desktop computer) It had partial function by mashing the caps lock key many times on an old Dell XPS 630, in Linux Mint ... maybe 17 or so. The same trick didn't work in Windows 10. It didn't work at all on any other computer I tried.

MF2 Keyboard

The expression MF2 keyboard stands for multi-functional keyboard version 2. This type of keyboard was first developed and defined by IBM for use with all types of PC (XT, AT, PS/2). In the meantime it has become an industry standard and today nearly all PCs have an MF2 compatible keyboard.

The MF2 keyboard supports 3 different sets of make and break codes. Code set 1 is used for XT/PC and PS/2 –30 compatible computers. Code set 2 is used for AT and all other PS/2 models compatible computers and code set 3 is used for workstations and terminal emulations on the PC.
