8085 Microprocessor card with 265 bytes of RAM and up to 6k
bytes to ROM. The card includes a timer, programmable from
200~S to 1.3 seconds, serial input and output ports, 3 x 8
bit and 5 x 1 bit buffered output ports, 1 x 8 bit and 3 x
1 bit bi-directional un-buffered ports all available on the
ren edge connector. Two additional 8 bit, 1 x 4 bit and
5 x 1 bit ports are available for connecting to switches,
lamps, test sockets etc. Power requirements 5V d.c.
Superseded by UN26/22A. OBSOLESCENT.
8085 Processing Unit. Partially equipped processor board
intended as a sub-assembly for an overall unit. This board
is an improved version of the UN26/22 with more RAMs, more
ROMs, a choice of processor speed and bi-directional ports.
Most software will be upward compatible but down
compatability is unlikely. Power requirements 5V d.c. 4U
