Build A 8085 Computer

The 8085 is the descendent of the 8080 arguably the microprocessor that kickstarted the personal computer revolution. This time it is the 8-bit 8085 from Intel although second sourcedcopied by a number of other manufacturers.

Its binary-compatible with the 8080 but requires only a single supply a crystal and an address latch to operate the 8080 requires three supplies a system controller IC and a clock.

Build a 8085 computer. Mint Container not included. This is my 2nd version of the MTK-85 Microprocessor Training Kit. Before building an 8-bit computer it is extremely useful to have a grasp on the elemental properties of electricity and analog circuitry.

Version 10 of the SBC-85 CPU board has been uploaded to PCBWAY and OSHPARK as a shared project. 20082018 I built a vehicle performance monitor around a 8085 UV EEPROM SRAM a floating point math coprocessor those dot matrix displays and a commercial 3 axis accelerometer. An Intel 8085-based computer Project Owner Contributor Bentendo 6004.

13042017 Glitch Works 8085 project didnt have an on-board UART. Build a Pocket-Sized Altair Computer. Build your own Microprocessor training kit with the Intel 8085 Microprocessor.

I documented the whole project in a series of YouTube videos and on this web site. 13032020 Decades ago I wirewrapped my first 8085 3-chip system with an 8085 8155 8755 and I was hooked forever. 01032020 We build a 8085 Single Board Computer.

The 8085 Microprocessor is a first and perfect design microprocessor among all who was having all the operation features to use on a computer. Building a minimal 8-bit computer. If you want to relive the early days of computing with a small 8085 computer board go out and build your own Altaids Computer.

The resulting design includes 8085 CPU 8251 USART 32 KiB SRAM 32 KiB or 16 KiB ROM. 16042017 The Glitch Works 8085-based Single Board Computer is another one of those cool little projects using ancient technology. I decided to rekindle my fondness for the 8085 by updating and creating an 8085 single board computer with an eye towards expansion.

The new gpio LED is. There are many electronics self teaching guides available for a minimal cost that provide a crash-course in electrical engineering. The platform is now the same as Z80 kit170 x170mm.

The Altaids Computer shows that retro-computing doesnt need to take up a lot of space. Watch this video for an introduction. Combining the LCD and Interrupts.

Read the full article at. 13092010 Having found an 8085 CPU in an old ATT PBX module given to me by a teacher in middle school Id decided that would be the processor Id use when I eventually got around to building one. I built a programmable 8-bit computer from scratch on breadboards using only simple logic gates.

02092010 In December 2009 I finally decided to build a prototype 8085 single-board computer as my IO needs were outgrowing the midrange PICs. The 8085 Microprocessor was designed by Intel in 1977 using NMOS technology. If you are interested in building your own Intel 8085 based single board computer the SBC-85 is a great educational platform.

29k 23 6 Project to try to figure out and do something with an Intel P8085 processor that I salvaged. The main operation 8085 Microprocessor ALU is arithmetic as well as logical which includes addition subtraction. Contribute to SensorsIot8085-Computer development by creating an account on GitHub.

The display is changed with the super bright LED LITEON LTC4727JR. Project Owner Contributor. Step by Step construction just as I did it.

The Free Run Circuit. There are parts on the computer you will build will need analog components. The prototype consisted of a Vector protoboard with all of the ICs mounted in sockets and soldered down to the traces.

Fairly heady stuff for 1988. It uses a GAL16V8ATF16V8 simple programmable logic device SPLD instead of discrete logic ICs for the address decode and the frequency divider for USART. Sure there are better processors but arguably none held onto their mostly industrial market share for so long.
