superHermes

superHermes from TF Services includes all the features of the Hermes IPC replacement chip and adds IBM AT keyboard interface, high speed 2-way RS232 at up to 460,800 baud, serial mouse port and 2 other RS232 inputs (i.e. 3 low speed RS232 serial inputs) plus 3 spare I/O lines. It will also handle a PS/2 keyboard with a standard PS/2 - AT adaptor.

It has a keylock connector (which locks QL/IBM keyboard and superHermes mouse), a Turbo connector (256 speed factors) and 1.5K of non-volatile memory EEPROM. It also has a connector for capslock/scroll-lock LED and a keyclick function which can be toggled on or off. superHermes is a plug in circuit board not much more than twice the size of the 8049 coprocessor it replaces on the QL or Aurora motherboard.

superHERMES uses a high speed RISC co-processor, a PIC 17C44. The maximum throughput is achieved when used with a Super Gold Card - with the high speed serial port set to a baud rate of 115,200, this gives a little under 80kbps.

Advertised features include:

Fixes serial input and serial overrun problems on the Sinclair QL serial ports.
Fixes keybounce (including for the Schön and Keyboards Products.
Provides independent baud input rates for ser1 and ser2.
Fully reliable serial input up to 19,200bps - allowing you to use any modem without the QConnect module from the Tandata Modem stack (this assumes that the input/output buffers (ICs 25/ 26) are fully functional, and that handshaking is enabled at both ends and connected).
Additional serial ports - 3 low speed serial ports (allowing use of a serial mouse) and a high speed 2-way industry standard serial port at up to 57600bps. Maximum throughput with Super Gold Card/qtpi zmodem into ram is 4800cps
Two key rollover, even with SHIFT.
Improved sound - 'fuzzy' and 'random' parameters on BEEP no longer change the underlying pitch. Duration of sounds are no longer dependent on the pitch.
Keyclick can be toggled on or off.
IBM AT keyboard interface with all major country layouts
Keylock connector (locks QL/IBM keyboards and sH mouse)
Turbo connector (256 speed factors)
1.5K non-volatile memory (EEPROM)
Connector for capslock/scrollock LED
3 spare input/output lines with +5v/GND
