- A real IIe will display either "Apple //e" (enhanced ROMs) or "Apple ]["
- (original ROMs).

-
- Sounds like someone did something funky to the character generator.
- Is it the standard character-generator ROM (with Roman characters) or
- is it a custom generator (altered, perhaps, to display Cyrillic
- characters)?

-
- Binary files are loaded in with BLOAD and saved with BSAVE.
-

-
- Depends on which cards you've installed. The I/O setup in the Apple
- II is a little bit hairy. :-)
-
- >5. Why when I do HGR and then LINE 1,1,2,2 it types OUT OF MEMORY ERROR?
-
- That second command doesn't sound like a BASIC command...but it should
- come back with ?SYNTAX ERROR. Try something like this:
-
- HGR:HCOLOR=3:HPLOT 0,0 TO 279,159
-
- That should put a solid diagonal line on-screen.
-
- >Why lowest part of screen remain text mode?
-
- That's the default for Hi-Res page 1. If you use HGR2 to use page 2
- instead, you'll get the full 280x192 graphics display. You can also
- POKE 49234,0 after HGR to view all of page 1.

- >7. How to copy files and system in DOS 3.3?
-
- Still using DOS 3.3...ick. Don't know if it'd be legal to send ProDOS
- 8 to you...in any case, you can copy the system software under DOS 3.3
- simply by formatting a disk; use INIT <filename> and a copy of DOS 3.3
- will be put on the disk. FID is a utility that will allow you to copy
- files under DOS 3.3.
-
- >8. How to I/O hexadecimals in BASIC? $d0 or D0H it doesn't understand.
-
- BASIC normally deals with decimal numbers exclusively. You can store
- hexadecimal numbers in strings and create your own routines for base
- conversion, input checking, etc. The coding is relatively trivial.
-
- >9. What is NOMON?
-
- Under DOS 3.3, NOMON is the start of a command that turns off disk
- monitoring. It's used when working with text files. Follow NOMON
- with I and you won't see files as they're being read. Follow it with
- O and you won't see files as they're being written. Follow it with C
- and you won't see files as they're being EXEC'd. The normal usage is
- NOMONICO, which kills all three types of monitoring. (The opposite,
- of course, is MONICO. It's all mainly a debugging feature.)
-
- >10. Is there more than 65k of memory and how can I access it with PEEK?
-
- If you have a memory card in the auxiliary slot, you have more than
- 64K. Accessing the memory under DOS 3.3 is non-trivial, however.
- ProDOS makes it a bit easier by configuring a 64K RAMdisk in auxiliary
- memory.
-
- >11. Can usual modem which I use in PC be attached, and how to manipulate?
-
- Depends...if it's an external modem, just plug it into a serial card
- and plug the serial card into your Apple. If it's an
- IBM-clone-internal modem, though, it won't work.
