CUBIT is a Eurocard sized (100 x 160 mm) microprocessor module with four main functions.
As an extension card to 6502-based computers, particularly the Rockwell AIM 65, adds 4K bytes of RAM memory plus a socket for a 2K or 4K byte ROM or EPROM. This socket can be arranged to take a further 2K bytes of RAM memory. It also provides a VIA (6522) input/output chip giving 20 i/o lines via a 26 way ribbon cable connector, and a 64-way DIN connector (which can take a 64-way ribbon cable) for connection on to the Acorn standard computer bus. This gives the user access to all the Acorn and Control Universal computer cards.
As a interface between 6502-based computers and the Acorn and Control Universal range of computer cards, which includes VDU cards, memory cards, PROM programmer, floppy disk controller and many more.
As a stand-alone single board computer. All the facilities described above are available, and the CU-KEY QWERTY keyboard and CUBOS operating systom, described separately in this catalogue, complete its usefulness as an independent computer. See also the section on the industrial Control Unit which allows the use of BASIC with CUBIT.
As a memory and i/o extension. When plugged into the data bus without a 6502 on board, all the facilities of and i/o can be accessed from the host computer.
The mark 5 version of CUBIT, which is the current issue, incorporates a 555 timer chip which provides power-on restart. This improves the usefulness of the card, especially as a single board controller. Fuller details can be found in the user manual on CUBIT, available without charge from Control Universal or your CUBIT dealer.
This version has wire-wrap tails on the microprocessor socket to allow it to be plugged into the micro socket of the host computer. No 6502 or crystal is supplied, but in place of the crystal a capacitive oscillator is fitted, which allows the card to operate as a stand-alone computer simply by fitting the 6502 chip. This arrangment runs nominally at 1MHz, but does not have the accuracy of a crystal.

Cubit and Acorn compatible graphics card, 8 colours in 512 x 256 pixels.
Uses the EF9366 graphics processor chip. Each plane of colour (red, green, blue) displays 16K bytes of memory, giving 512 x 256 resolution; each pixel can be red, blue, green, white, yellow, cyan, magenta or black.
Only 256 bytes of the host computer memory are used, all 48K bytes of screen memory being on the memory map of the EF9366 only.
Text display can be superimposed on graphics, and can be up to 85 columns by 32 rows, using an on board generator of 96 standard characters. Each character can be scaled for height, width, slope, and orientation, all independently.
The user can define his own character set without restriction and can also, by defining a picture display unit as something larger than a single pixel (eg. 4 pixels wide by 2 pixels high) obtain a vastly increased palette of available colours, although at reduced resolution.
The EF9366 also permits fast hardware vector generation and light pen user input. The CU-GRAPH memory can be interrogated by the computer for output to monochrome or colour printers.
Outputs are provided as RGB and sync. CU-GRAPH is constructed as two boards called CU-GRAPH-mono and CU-GRAPH-extension, together they are referred to as CU-GRAPH-full colour. CU-GRAPH-mono is a Eurocard using the standard Acorn data bus and carries the EF9366 processor, address decoding and the 16K bytes of dynamic RAM required for full graphics resolution in monochrome. There is also an output suitable for driving a bleeper to provide a BELL signal so completing the use of CU-GRAPH as a terminal. CU-GRAPH-extension is a similar sized board mounted piggy-back on CU-GRAPH-mono. It carries the further 32K bytes of dynamic RAM necessary for 3 planes of colour at full resolution, plus a centronics type printer interface and 26 way ribbon cable connector.
Driver software for use on Acorn and Cubit systems is available now, together with a high resolution graphics version of Acorn Atom BASIC.

CUBAN was developed jointly between Control Universal and MEDC, Paisley College, and appeared in a series of articles written by Peter Williams, John Ferguson and Jake Stewart in Wireless World, under the series title of "Interfacing Microcomputers'.
CUBAN is a Eurocard with the standard Acorn microprocessor bus, and so can be used with all Acorn and Control Universal processor cards, and via an interface card with a range of other microcomputers such as PET, Apple, TRS80, ZX81 etc. It is particularly relevant to educational uses as it combines digital input and outputs, analogue inputs and outputs, and a means of simulating digital inputs and outputs on board.
The National ADCO817CCN has a conversion speed of 100 microseconds per channel, and can have time constants applied to each of the 16 channels individually, or to all at once, or both, and there is on-board provision to do this. The accuracy is plus/minus one bit, or, with the alternative ADCO816CCN device, is plus/minus half bit.
The Ferranti ZN425E has a conversion speed of 1 millisecond. There is provision for fitting an LM317T regulator on board, which allows the user to regulate the board supply of 5V to exactly 2.55V, thus arranging for each bit to represent 0.01V.

CU-MEM is a Eurocard using the standard Acorn bus, with eight 28 pin sockets,
each of which can take the industry standard range of 24 and 28 pin memory
devices, offering RAM, ROM and PROM options. The sockets are arranged in two
banks, which can be individually selected for their position in memory (in 8K
divisions) and for the type of memory device used. This allows the popular
option of a bank of RAM (up to 8K) and a bank of PROM (up to 16K using the 2564
or similar).
All CU-MEMs are sold with automatic power-on reset, which both helps protect the battery-backed RAM from corruption, and gives automatic power-on start for Acorn systems which do not otherwise self-start.
Every CU-MEM also has a battery for preserving data when CMOS RAM type 5516 is used. Note that 6116 type can be used in the CU-MEM, but does not permit battery backup. The battery is trickle charged at all times that the board is supplied with its normal operating voltage of 5V, and, when fully charged, can be expected to hold up the memory for several months, The length of time of data retention is influenced by temperature, battery age, manufacturing tolerance variations of the memory chips' consumption and the number of charge/discharge cycles that the battery has gone through. When the power is lost at the mains, the voltage decays over a short period of time from 5V to 0V. As the value passes 4.5V, the CU-MEM generates a RESET on the microprocessor, thereby preventing random writing cycles which could corrupt the data.
The following are some of the types of memory that can be used on CU-MEM, many of which are offered for sale in the integrated circuit section of this catalogue, section 14.
RAM Mostek 4802 (2K bytes) Toshiba 2016 (2K bytes), 5516 (CMOS 2K bytes, suitable for battery back-up) Hitachi 6116 (CMOS 2K bytes, not suitable for battery back-up) Intel 2816 (2K bytes) ROM Rockwell 2316 (4K), 2332 (4K), 2364 (8K) EPROM Texas 2516 (2K), 2532 (4K), 2564 (8K) Intel/Mostek 2716 (2K), 2732 (4K), 2764 (8K) EEPROM Hitachi 48016 (2K)

CUBIO carries four 40 pin sockets and is an exceptionally versatile unit that allows the use of either the cheaper Peripheral Interface Adaptor (PIA), which is sold as either the Rockwell 6520 or the Motorola 6821, or the more expensive but higher performance Versatile Interface daptor (VIA), which is sold as the Rockwell 6522. PIAs have 16 i/O lines, as has the VIA, but the VIA has in addition 4 control lines, which can be used as i/o, two timers, serial/parallel and parallel/serial shift registers and interrupt handling facilities.

CU-DRAM is a new development by Control Universal scheduled for deliveries in August 1982. It utilises eight 64K bit dynamic RAM chips to give 64K bytes. Since most microcomputers require part of their memory map to be reserved for an operating system ROM and input/output devices the card is provided with 16 switches which allow the user to de-select those areas of memory which are used for other purposes. This can be done in blocks of 4K, and may be in any combination of selected and de-selected 4K blocks. A block is defined as starting from X000 to XFFF in hexadecimal, where X is the code selected from 0 to F.
The devices used require a 5V supply only and are rated at 280ns. The board design allows the RAM to be used at more than 1MHz, and when the faster RAMs become available, the board will be able to operate at 2MHz.
In addition, CU-DRAMs can be used together, up to 16 at a time, by writing to their their board select register, which will select one out of 16 to be active. Each CU-DRAM is defined as being bank number 0 to 15 by links. By this means, CU-DRAMs can provide up to 1MByte of RAM.
There is also a 28-pin PROM/ROM socket for a 4K or 8K device into which is plugged a replacement for the host computer's firmware resident at hex F000 to FFFF. This prevents memory address clash when the board select facility is used.

CU-PRINT is a new development by Control Universal scheduled for deliveries in August 1982. It employs a 6522 i/o chip (VIA) with two 16 position rotary switches to provide decoding down to page (256 bytes). It can be used with all CUBE/Acorn bus systems to provide connection between the processor and a printer with a Centronics type parallel printer interface.
This card is especially useful with graphics printers as all eight bit are valid and controllable.

53 key non encoded keyboard (keys are decoded by polling from the operating system, each key has a place on the cross matrix) designed to plug into CUBIT, CUNINE or CUMOT single board computers. The new CUBOS operating system for the 6502-based CUBIT supports this keyboard, which, together with CU-MEM, Acorn 40 column video card and Acorn Atom BASIC make up the Industrial Control Unit described on page 1.5.
The RESET key is protected by a time delay from accidental operation. To use the RESET the key should be held down for longer than 1 second.
CU-KEY is currently sold unenclosed. A case has been commissioned and should be ready in the third quarter of 1982. It will include provision for a 25 key numeric and function keypad.

Control Universal backplanes are designed for mounting standard Eurocard DIN sockets on 1" spacing. The DIN type code is 41612, and the version is 64-way using rows a and b.
The backplane PCB provides bus connections between all of the A row pins, and between all of the b28 (IRQ), b29 (NMI) and b30 (sync) pins. Pin 19 is regarded as committed to supplying the EPROM programming voltage of 26V for use with the EPROM programmer.

The first socket on the backplane has long wire wrap tails, and so allows a 64 way ribbon cable to be plugged onto the back of it without the use of a bus extender card. The cable is shown on page 17.1 and allows a rack extension to be used with the AIM 65 and the Atom.
The module illustrated fits a standard 5.25" mini-floppy disk drive into a Eurorack. See the sections on Acorn System 3 and 4 for illustrations of fitting one drive into a single height rack, and two drives into a double height rack.

The following Control Universal software represents "application routines", ie. those pieces of operating software, or "Firmware" which permit the user to employ Control Universal products in a particular computer system.
CUMEX AIM 65 monitor extension for driving video display and external Centronics type printer. It is 835 bytes long, and is specific to either the Acorn 40 or 80 column VDU interface cards, for which this is a full solution including properly executed delete routine. Execution of this program (ie. type *=GHJK {return} G {space} ) causes the CUMEX program held at hex GHJK to alter the AIM 65 ouput vector so that the output stream goes to the video and to the expansion connector for the external printer as well as to the built-in 20 column led dispay and thermal printer.
PROMER is the program for using an Acorn EPROM programer with the AIM 65. For convenience, this program is included in the same chip as the video and printer driver, which is then supplied in the same form whether for video and printer, or for the PROM programmer, or for both.
