All of this talk about the apple ][ emulation board for the LC has lead me to ask a question. What about the third party software package called ][_in_a_mac which is suppose to emulate an apple ][ entirely in software. I havn't seen this product so much as mentioned in the discussions. Even in those asking about apple ][ emulation for macs other than LCs. Has anyone had any experience with ][ in a mac? Is it any good? Does it emulate a ][ well? What kind of ][ will it emulate up to (ie a ][+, ][e, double hiRes?) Seems funney to me. ====== == ###### ###### == == .................. == .. ### ### .................... ====== == == === ===== == ==== ### ### ...................... == ... == == == == == == ====== #### .purplex@nacjack.gen.nz. == .... ===== == ===== == ==== ### ### ...................... ................... == ......... ### ### .................... == ###### ######

(Re: II in a Mac) II in a Mac is a fun little toy to play with, but if you want serious Apple II emulation, forget it. First off, you have to convert disks, through a null-modem cable hooked between a II and a Mac, before you can use them. You can, however, mount an 800k-formatted 3.5" floppy directly, if you're using a SuperDrive. (the new 1.44M floppys that are in the newer machines) The emulator itself is extremely slow, because it emulates a 6502 (not 65C02), entirely through software. On a Plus or Classic, it crawls. On an SE/30, it's a little better. The program maps slots to their Mac equivalent; slot 1 is the printer port, slot 2 is the modem port, slot 5 and 6 are disk drives, etc. It has 80-colum and graphics emulation built-in (lo-res and hi-res). I ported several AppleSoft baSICK programs onto it, and ran them, success- fully, but they crawled. I even ran a BBS system on it, which was written half in ML, half in BASIC, AND IT ACTUALLY WORKED!! slow as molasses however. If you just wnat something to fool around with, then II in a Mac is ok. But if you want to do some serious application running, like AppleWorks or the like, then forget it. ______________________________________________________________________________ Donald Burr, Univ of California, Berkeley | "I have a seperate mail-address INTERNET: c60a-cz@danube.Berkeley.edu | for flames and other such nega- or: 72540.3071@compuserve.COM | tive msgs; it's called /dev/null."

The ][ in a mac software runs fairly well on an si range machine. It does not support color and supports 80column text but not DHGR. It runs pretty good in 1 bit video but not at 8 bits. It emulates a non- enhanced apple//e I believe. (ie cannot run stock appleworks) It also double buffers by redrawing the screen completely instead of having screen ready bitmaps of both HGR screens and just using copybits. The result is that in programs which use page flipping for smoother animation the emulation really slows down. I also found some bugs in its emulation. I could not run some graphics programs under it (read: some games hung up the emulation). Alternatives: The UNIX //e emulator (ftp isca.icaen.uiowa.edu) will emulate an Apple//e enhanced (ie runs appleworks) under AUX. It only emulates text modes but it is FREE. There is a standard MAC version in the works (probably TEXT, GR, and HGR) hopefully done early 1991 and it should be FREE (or at a very minimal cost). -- rjf.

I wish they could implement something like the file sharing architecture in SoftPC Anyhow I remember playing around with II in a Mac (don't have the program) and remember that it does emulate a 65C02 (the monitor actually disassembled 65C02 instructions). On the SE/30, it seems to be faster than the II Plus that I have. U dont need a SuperDrive to read ProDOS disks... that's a joke since both ProDOS and HFS use the same GCR formatting. I did hear that this is a very poorly supported program.. and wonder if it really works on a Mac II. +-----------------------------------------------------------------------+ | Calvin Cheng | | calvinc@ocf.berkeley The Best is Yet to Be! | +-----------------------------------------------------------------------+

Before I get into this, I should warn people that I'm not exactly impartial on this topic. I'm part of the development team for LC's Apple IIe Card.

There is no way to convert copy protected software, which includes probably 90% of all published software for the IIe. >The emulator itself is extremely slow, because it emulates a 6502 (not >65C02), entirely through software.

Programs that rely on a different configuration are out of luck. It's also missing a few potentially useful "cards" like the Memory Expansion Card and an AppleShare Workstation Card. >It has 80-colum and graphics emulation built-in (lo-res and hi-res). It also does 40-column text, but not double hi-res. It is also limited to black and white graphics. >I ported several AppleSoft baSICK programs onto it, and ran them, success- >fully, but they crawled.

"II in a Mac" does work, albeit slowly. It also has the advantage that it will run on any Mac, not just an LC with a card. >______________________________________________________________________________ >Donald Burr, Univ of California, Berkeley | "I have a seperate mail-address >INTERNET: c60a-cz@danube.Berkeley.edu | for flames and other such nega- > or: 72540.3071@compuserve.COM | tive msgs; it's called /dev/null." ========================================================================= Paul Wenker UUCP: prw@apple.com Apple Computer, Inc.
