- Hi Folks,
-
- Here's what's up with Executor 2.0 for all platforms. I am sending
- this e-mail to the Executor Interest mailing list and also posting
- it on comp.emulators.misc.
-
- Mat Hostetter has almost finished major modifications to our
- synthetic CPU (the original one was written by Mat too), which
- should bring the CPU performance of Executor up to where a 90 MHz
- Pentium performs integer calculations at about the speed that a 50
- MHz 68040 would. Exceedingly good, when you compare how quickly
- our emulator emulates a 68040 on a Pentium to how quickly Apple's
- emulator emulates a 68040 on a PowerPC.
-
- We have many new versions of Executor in the works. All of them
- are awaiting the new synthetic CPU. We're doing non-synthetic CPU
- work as well, but it doesn't make sense for us to release anything
- between now and next week when we think the new synthetic CPU will
- be up and running. Here are the new versions that we're working
- on. We are also rewriting our literature to document exactly what is
- available now and what will be in 2.0 and what will have to wait for
- 2.1 and beyond.
-
- Executor/DOS 1.3 Commercial
-
- This will be the the last monochrome version that we release.
- It will be sent free of charge to anyone who has previously
- purchased any version of Executor/DOS and sent in the registration
- card. This version will also be a key that can be used to
- unlock commercial versions of the color experimental versions
- of Executor. There will be no fee to use these experimental
- versions as we finish work on 2.0.
-
- Executor/DOS 1.99a Commercial
-
- As work progresses on the release of 2.0, we will be making
- experimental versions designated 1.99a, 1.99b, etc. available
- for our current customers to use and comment on.
-
- Executor/DOS 1.99a Demo
-
- In addition to allowing our current customers to see our color
- version, a time-limited demo version will also be made available.
- In addition to the time limit, the demo version will not allow
- you to access CD-ROMs or disks.
-
- Executor/Linux 1.99a
-
- Internally we're doing almost all our development under Linux.
- This version will allow people with Linux to see what Executor
- looks like under X-Windows. It will have a time-limit that
- can be removed with an activation key. The price for this
- activation key hasn't been set yet.
-
- Executor/NEXTSTEP 1.99a
-
- We haven't forgotten our original customer base, and we should soon
- have a color experimental version of Executor for our NEXTSTEP users
- to use.
-
- After these releases have come out, we will automate our experimental
- release process so that the DOS, Linux and NEXTSTEP versions are all
- released simultaneously and with little hassle over here. Less hassle
- for us turns into more frequent releases.
-
- Some of the new features that have been added into Executor between our
- last experimental DOS release and now include:
-
- Executor can now read and write SCSI disks that are not seen
- by the BIOS if you have an ASPI manager that does see them.
-
- There's a more efficient one-bit-per-pixel (i.e. black and
- white) mode of the color version of Executor.
-
- The color version of Executor works on more VESA compliant
- graphics cards than it did before.
-
- HyperCard works much better under Executor than it used to --
- it's fast enough to be usable, and many bugs have been fixed.
- There are still some major problems, and many stacks won't run
- at all, but the major impediments to HyperCard running under
- Executor have been found and fixed.
-
- In addition to all the work described above, Bill Goldman has been
- writing a Graphical User Interface to the filesystem, a filesystem
- browser, that will be released *with source* when it is a little
- more stable. Releases of it will usually not have to be timed to
- coincide with Executor releases, since it *should* just drop in
- without many hassles.
-
- For those of you who aren't familiar with the work that we've done
- on supporting color, what we've done is supported most of the calls
- in "32-bit color QuickDraw", although the number of bits per pixel
- that we support on the screen is currently limited to 1, 4 and 8.
- Our original plan for 2.0 was only to support the color model that
- was available on the first Macintosh II, so just like our synthetic
- CPU improvements, we are winding up supporting more in terms of
- color than we originally intended. The drawback is we still have
- a few routines to finish and the debugging effort is also much
- harder than debugging the original color model.
-
- On the e-mail front, our transition to a new internet provider was
- a little more rough than we realized. Apparently many sites were
- not able to send e-mail to "@ardi.com" addresses, and in addition,
- because of the bouncing, I was off the Executor Interest mailing
- list for a while. E-mail that is addressed to "question@ardi.com"
- should be responded to fairly promptly, e-mail sent to me, is
- usually examined in batches, in between major amounts of coding,
- and is frequently just forwarded to questions@ardi.com for Vaune
- Fischer, our technical support person to handle.
-
- You now know what Bill, Mat and Vaune are doing -- I'm doing almost
- everything else, which includes technical work and discussions with
- potential investors and partners. Work of the latter type temporarily
- takes me away from programming, but we would very much profit from
- having a few more engineers on the payroll, and I'm working on a
- few different ways to make this happen.
-
- Since this letter is a de-facto acknowledgement of the folks who
- have done the most work on Executor over the last few months, let
- me publicly thank Cotton Seed for his implementation of Color
- Quickdraw. Cotton is back at MIT now, but we hope to have him
- working for ARDI again in the future.
-
- BTW, ftp.cs.unm.edu is currently the location where we first make
- experimental versions of Executor available (in the pub/ardi
- directory), but since that site has severe limitations on the number
- of people that can access it simultaneously, we'll also get the
- 1.99 experimental versions onto the the appropriate sites for
- finding DOS, Linux and NEXTSTEP stuff.
