Get an 80 col card (suggestions ?) Videx-compatible 80-column cards seem to be the most popular, but I never owned a II Plus, so I couldn't say for sure. I think the only company that makes 80-column cards for the II Plus anymore is Applied Engineering, with their Viewmaster 80. (Videx-compatible and everything-else-compatible, as is every- thing from AE.) > b. Modify shift key to include lower case letters (how to do this ?) Some companies sell shift-key modifications, but I have a magazine article from 1984 that tells how to do this modification yourself. You say you have a Revision 1 motherboard, so here goes: 1) Remove the cover from the computer. Remove all cards from the slots. Remove the motherboard from the case. Remove the bottom of the case from the rest of the case. Turn the case/keyboard unit upside-down. 2) At this point, the keyboard's curcuit board should be visible, with a 40- pin encoder chip in the lower left corner of the board and the keyboard cable in the upper left. Cut, strip, and solder a wire between pin 16 of the keyboard cable header (you'll see it as the upper-right corner of the header) and the leftmost contact of the three contacts on the SHIFT switch. (This switch is labeled number 53; the number is over the rightmost contact. Go over two more contacts and solder the wire to that terminal. 3) Reassemble the computer. This is probably not the best description. Again, I've never done this, so don't come crying to me if you fry the motherboard. If you're not completely confident that you can handle this, buy one of the commercial modification kits. > c. Get a SuperSerial Card (suggestions ?) > d. Get an external modem (2400 - which) If the SSC is intended to be used with an external modem, I'd get an internal modem instead. The Applied Engineering DataLink 2400 has an SSC front end and works like a Hayes Smartmodem 2400. > e. Terminal software ( I heard Kermit will run under dos 3.3) Yes, it will, but you'll need ProDOS to get a copy at all (more later). > f. Optionally, substitue d,e with an internal modem (?) As far as I'm concerned, internal modems are the only way to fly. They fit inside the computer and don't collect dust on the outside. If you ever move, all you'll have to do is disconnect the phone lines from the connectors on the back. An external modem is more hardware to pack up. Besides, an internal modem costs less than the equivalent serial-card/external-modem combination. >Is this the correct minimum for turning the above apple into a vt100 terminal? Add a 16K "language card" to the list. These cards are still available from several sources--hell, AE came out with a new design for this type of card, the Pocket Rocket, just a couple of years ago! (Their design uses only four chips.) You'll need the language card to run ProDOS. A second 5.25" drive (plenty of Disk II clones out there) and more memory beyond 64K would also be nice. The language card is an absolute must-have--no serious commercial software will work with less than 64K anymore. >Lastly, I would like to find out what is exectly 'ProDOS' (short of >being a better DOS, I guess) , is it a comercial product, what is the >most recent version of it, and what are the hardware requiraments for >running it. What are the benefits of having it ? ProDOS is, for all practical purposes, THE operating system for the Apple II today. It offers many advantages over DOS 3.3: speed, a hierarchial file structure, the ability to use 3.5" disks, hard disks, and RAMdisks, and other features too numerous to mention. The only software anymore that uses DOS 3.3 are copy-protected games that use modified versions of DOS 3.3. You can almost (but not quite) be guaranteed that ProDOS-based software will not be copy-protected and can be moved to a hard disk at a later date. ProDOS requires 64K, so you'd better get a language card (but I already said that!).
