    PicoRAM 6116 - RAM Emulator & SD Card Interface for the Multitech Micro-Professor

    PicoRAM 6116 is taking Microprofessor MPF-1B software development to the next level - instead of keying in hex codes with the monitor, use a comfortable state-of-the.art Z80 assembler on the PC or Mac, assemble / compile the HEX file there, put it on SD card, and feed it to the Microprofessor...

    Performance of Radio Shack's 1976 Science Fair Microcomputer Trainer

    Yeah, just not very feasible... I guess the Pico could control a relay-based switch matrix, instead of the spring wires :ROFLMAO: As for the Science Fair Microprocessor Trainer, it's not really set up for electronics experiments, as there is only one way of wiring it up, really. No GPIO is...

    Performance of Radio Shack's 1976 Science Fair Microcomputer Trainer

    So here's the catch - just got mail from Jason. And Jason said that this thing did debut in 1985 (!), not 1976. I am guilty of copying BS from the Web. He sent me this link to the 1985 RS catalog: https://web.archive.org/web/2013/http://www.radioshackcatalogs.com/html/1985/h155.html That makes...

    It's weird - he is using the Pico to push the INCR button, basically... not sure this counts as an extension or "enhancement" to the system. The Pico offers great potential for building hardware extensions for such systems though - for example, check out my PicoRAM 2090 for the Microtronic...

    Review and evaluation of some vintage educational computer systems

    Very cool: "By the 1960’s Irving Becker was developing many educational products, including the digital computer CT-650 and a cardboard kit for Bell Laboratories, called CARDIAC (a reference to its cardboard construction and the names of other kits like the popular Simon, Brainiac and Geniac of...
