Retrochallenge Update

I’ve made a fair bit of progress today, tidied up a fair amount of code, resolved a number of issues that were returning slightly odd results when the player did unexpected things.  I came across some documentation that alluded to setting parameters for the target displays  Sad I know but this was quite exciting given the limitations of the PX-8’s display and the fact that the only CP/M interpreter I have doesn’t as far as I know allow you to specify display settings.

I therefore compiled a version for the PX-8’s 80 column by 8 line display and while I was as it one for the PX-4’s 40 by 8 display.  I transferred them over and… it didn’t work.  At the moment I don’t know why it’s not working and I also don’t know why I took some video of it not working but I did.

  1. Hi
    I have just been scanning around for PX 4 – with a view to selling mine – yet I have found a bunch of people messing around with them, which I find fascinating!

    Not sure if I can help, but in 1987 my job was to support resellers of all devices (produced by the division Epson Special Products) but particularly PX4, PX4+, EHT10, PX16.

    What are you trying to do?
