Re: [M100] z88 and tandy portable disk drive

Just to be clear, I'm not suggesting you actually get all the stuff to build a Feather MounT for Z88 and get an Adafruit Feather board and run PDDuino on it, unless you actually wanted to play with something new and shakey just for the fun of it. It's neat, and it mostly works, but the code

Re: [M100] z88 and tandy portable disk drive

Ooh I can add a Z88 version of https://github.com/bkw777/MounT to use with https://github.com/bkw777/PDDuino too. Though, the 1ma power output from the DTR pin on the serial port isn't enough to power a Feather or Teensy. The Mode T's except for KC-85 all have a BCR port which provides enough

Re: [M100] z88 and tandy portable disk drive

Good grief the pin numbers for the DE9F are wrong on that drawing too. I can't make sense of that drawing at all, and so I'm ignoring it. I'm going to go by the actual user manual. That too has one slight confusion but not really. At first glance it looks like it's saying there is a 9pin male

Re: [M100] z88 and tandy portable disk drive

Also the pin numbering for the tpdd socket is wrong on that drawing. There is a standard for how pins are numbered on plain pin headers and IDC connectors, so, the visual description of which wires go to which pins may be correct, but only consider those pin numbers within that drawing itself. The

Re: [M100] z88 and tandy portable disk drive

That cable diagram doesn't show anything to translate between TTL for the drive and RS232 for the computer. Maybe it still works by luck but I wouldn't use it. The drive uses TTL voltages that range from 0 to +5v, while RS232 uses voltages that range from -N to +N, where N is anything from 5 to

Sounds like a cool experiment! I recently acquired a Z88, so maybe I'll give this a try, once I get a chance to dig into that machine a bit. On Sun, Sep 6, 2020 at 2:39 PM dano none wrote: > > Has anyone tried hooking up a Tandy Portable Disk Drive to a Cambridge Z88? > > The instructions are

Has anyone tried hooking up a Tandy Portable Disk Drive to a Cambridge Z88? The instructions are here: http://www.rakewell.com/xob/xob.shtml I think in the instructions to build a cable is says front of connector, I think that means - looking in to the cable from the front. Anyway, has
