Microflex 65 is the name given to the range of Eurocard modules made by Rockwell to be both an extension to the AIM 65 and a stand alone modular Eurocard rack mounted computer. The 64-line bus offers memory addressing up to 128K bytes, and allows any card in any slot. A range of cages (4, 8 and 16 way) permit a variety of packaging configurations.
166 RM65-1000E Microflex single board computer £121 Integrates a 6502 CPU, 2K bytes of static RAM, 16K bytes ROM capacity, 6522 VIA onto a Eurocard. Selectable memory map compatibility with AIM 65 allows programs developed on AIM 65 to be installed on this SBC. 165 RM65-3108E Microflex 8K static RAM card £171 Carries 8K bytes RAM in 2114 devices in two 4K blocks. Starting addresses of each block is selectable by switch, and a further switch allocates the block to one of two 64K banks, allowing the CPU to select from 128K bytes. 171 RM65-3132E Microflex 32K bytes dynamic RAM £171 Arranged in eight 4K blocks which can be selected in 4K blocks, and assigned to one of two 64K banks. The entire module can be write tested by a switch. Refreshing is automatic and transparent to the CPU. 170 RM65-3216 Microflex 16K PROM/ROM module £58 Eight 24 pin sockets each allowing a RAM or ROM of up to 8K bytes. Switches allow independent setting of the start addresses of 4K memory blocks. Choice of 2, 4 or 8K byte memory device is by jumper. 167 RM65-5101 Microflex Floppy Disk Controller £246 Controls up to four 8" or 5.25" drives, single or double sided soft sectored. Single or double density nay be selected under software control. Price includes ROM firmware for Disk, File and Directory functions. 168 RM65-5102E Microflex CRT controller (VDU card) £118 Monochrome output to monitor or TV (via on board RF modulator). 5x7 matrix in a 7x10 field provides alphanumerics and symbols from on-board character generator. 172 RM65-5222E Microflex General Purpose I/O and Timer (GPIO) £118 Provides two 6522 VIA devices offering a total of 40 i/o lines plus 4 timers. Can be assigned to one or both of the two 64K memory banks 200 RM65-5451E Asynchronous Communications Interface Adaptor (ACIA) £136 Interfaces two independent asynchronous serial i/o channels onto the bus, each of which may operate as a data terminal or data set, selectable by jumpers. Both RS232C and 20mA TTY current loop are provided on channel 1; RS232C on channel 2. Uses 6551 ACIA device. RM65-7004E Microflex 4 slot card cage £86 RM65-7O04NE Microflex 4 slot PCB only £12 RM65-7O08E Microflex 8 slot card cage £142 RM65-7O08E Microflex 8 slot PCB only £19 RM65-7016E Microflex 16 slot card cage £216 RM65-7016NE Microflex 16 slot PCB only £34 Cages have integral card guides. Allows extension to AIM 65 through a buffer module (code 180). May be mounted in a variety of orientations. Accepts axial module cooling fan. Screw terminals provided for power connection. 175 RM65-7101 Single Card Adaptor for AIM 65 to one Microflex module £36 One end plugs directly onto the AIM 65 expansion connector, and the other onto the Microflex module to be used. 173 RM65-7102E IEEE 488 Bus Controller module £177 ROM-resident firmware implements all the bus functions specified in the IEEE 488, 1978. A TI 9914 GPIB adaptor interfaces the 16-bit GPIB to the 8-bit Microflex bus. Address, data and control lines are buffered. 180 RM65-7104E Adaptor/Buffer Module for AIM 65 to multiple modules £52 Consists of an adaptor, two cables and buffer module that connects an AIM 65 to the expansion cages. The adaptor plugs onto the AIM expansion connector. 190 RM65-72O1E Design Prototyping module £25 Plain card with pre-routed power and return lines, and connector pattern, with holes for wire-wrapping prototype circuits. 195 RM65-7211E Extender Module £27 Allows a module to be accessible by an engineer while remaining plugged in to the bus. 191 RM65-7116E Microflex Cable Driver module £68 As code 180, allows AIM 65 to be connected to multiple Microflex modules, but in this case the cage may be up to 6 feet away, where the standard unit is limited to 16 inches.
