Thread: "most useful" Apple II+ cards?

  1. #1

    Default "most useful" Apple II+ cards?

    Hi all,
    I've just completed and tested my replacement for the 16K Language Card:
    https://www.youtube.com/watch?v=1KPIAoO1dTU

    Now, what is the next most useful expansion card for a ][+ machine (actually an europlus)?
    I'm considering to make a PAL card, a Z80 card, an 80 column (MC6845 based) card, a generic banked RAM expansion and even a disk II controller card if I'm not going to find one cheap for sale in EU.
    What everyone thinks is more useful (besides the disk interface that I'm anyway going to either buy or re-produce)?
    Also I've seen quite a lot different disk drive interfaces that are not looking like the Apple's one clone, for example a 4 port one from Franklin (afair). Unfortunately I haven't been able to find any schematic for those alternative designs.
    The only issue (for me) to design an exact clone of the Apple disk II interface is that I can't currently program the bipolar proms. Does anyone have any alternative schematic for those interfaces?
    All suggestions are welcome.

    It is easier to convert your Apple2 to NTSC standard (and the resulting colors will be more authentic) by switching several solder junctions and adding a few passive components if missing on the motherboard and changing the crystal to 14.318 MHz. If you are using CRT you will have less flickering because NTSC framerate is 60 Hz.

    Thanks George.
    I did miss the cheap compatible floppy controller on ebay, that will probably be the best choice.
    I thought about converting my europlus to NTSC, I'm really tempted, but I have the bad habit to leave my computers as much as original as I can.

    80 column card, one with a lower-case solution.

    I have found the "videoterm" 80 column schematic, I don't know if it has a lowercase solution too.
    Any suggestion to what was the "best" or "standard" back in those days? I'm young enough to have only been playing with the IIe in the good old days.

    The original Apple2 video output is NTSC anyway. The European version is somewhat crippled to me. As a child I was not pleased by euro clones we had at schools that used to produce only B/W video signal. Anyway NTSC TV sets/monitors were unobtainable those days in my country so RGB cards were a better option. I forgot to mention that to me the Apple Super Serial Card is important these days since it allows easy transfers with the adtpro software.

    I have two original SSCs with original manual
    And by the way, I also have a working //c to transfer programs to floppies with ADTpro.
    In the good old days, I thought that IIe were monochrome, since I've never seen one with a color card. I agree that the euro versions might seem crippled, but it's not super difficult to find or make a color (PAL, RGB, whatever) card.

    Not sure. I've seen probably half a dozen different ones.

    Don't tell me that your //c is also euro version . It is much more difficult to convert //e or //c to NTSC since this usually involves a replacement of IOU. As a pupil I had been using euro apple2 clones for some 5 years until on a foreign exhibition I had a chance to see an authentic real Apple //c with original color monitor which impressed me then. Nowadays I don't have a //c and I don't plan to buy one since it has no expansion capabilities and I don't like it. Unlike you I never thought that Apple2 was monochrome because I knew that even its BASIC included color operators. Don't underestimate the RGB cards. There are a lot of differences in the quality of the image they output. I've tried the majority of commercial ones and I like the one that was not designed by me and its vintage design still amazes me because of its very clever engineering. Here is one example of what it outputs on a PC unmodified CGA CRT monitor.

    Well, of course my //c is the euro version. I have never seen colors out of it But it was free, so I don't complain.
    I could easily make a PAL adapter on the video port, but I've never really needed colors so far. Apple IIe was in my school and that was mostly for programming. At home I had a VIC-20 first then a C64, and these had colors
    What RGB card do you recommend for the ][ anyway?
