Thread: Pro-Character ROM for Kaypro 4'83

  1. #1

    Default Pro-Character ROM for Kaypro 4'83

    Hi all,

    I'd like to replace my Character ROM in my 4'83 (81-240 MB w/ Pro8 ROM). I have been searching high and low for a BIN or HEX of MicroCornucopia's Pro-Character ROM to no avail. Any pointers to where one is archived, would be greatly appreciated.

    thx

    I'm not sure if the Character ROM will work in all models. I have the Char ROM for the Kaypro II, but
    I can't locate my EPROM file. I'm sure I copied it.

    These sites have some ROMS:
    http://www.retroarchive.org/maslin/r...pro/index.html
    http://www.z80.eu/kaypro.html
    http://www.microcodeconsulting.com/z80/kayplus.htm

    But, I don't see the PRO8 Character Generator ROM.

    Larry,

    Thanks for the followup. I have been to those sites and others and could not find the Pro-Character ROM. I think my last hope is that someone replaced their stock 81-146 Char ROM with this upgrade, still has the machine, and is willing to image it for me, or let me borrow it to image the data. Maybe they were not that popular of an upgrade?

    I can't say that the stock 'y' 'p' 'g' really bother me that much, but the ad has me curious on how the improved character set would look...

    I've attached an img of what I'm looking for, just in case it jogs someone's memory.

    cheers

    Al,
    I have the Kay-Pro GREEK Pto-Char IC in my Kaypro II.

    I'll try to get it read and saved in the next couple of days.

    I thought I had saved a file of that already, but haven't located it.

    Purge your PM inbox so I can PM you.

    Al,
    This certainly was an interesting find. There are ONLY eight Characters that are different from the KAYPRO II and the
    PRO8 GREEK Character ROM. Those changes are noted below.

    I know the spacing is off for this font, but it is at least close.

    I inserted the Bits from both the Kaypro II 81-146 (same as the 81-146a from Maslin Archive) Character ROM and the PRO8 GREEK ROM
    to the standard layout Page in BMP format.

    It gives an easy way to view the characters.

    If anyone is interested I can send the Images via email. Just PM me.
