V3.7 EO-X-37.zip

- Updated the emulated ZXpand firmware to V2.2 as required for 'Commander' (Supplied as menu.p)
- Now uses a sub-folder instead of a card image for SD card emulation.

The new sub-folder method is more convenient but the accuracy of the emulation is slightly impacted. With a card image I can be sure that the file-system access behaviour of EO is almost identical to that of a real ZXpand. However, the nuisance of preparing card images was beginning to irritate me, and Prime did a very good job of convincing me that a sub-folder was the way forward. (He doesn't know this, yet..!)

I may well offer a switchable approach in a future release, but this will require changes to EO itself. For this release only the ZXpand simulation DLL was updated.

Possibly bug in EO with ZX80 and 16k RAM ?

I have the version 1.0 (Test a).
When using ZX80 and 16k (with ZX80 rom) there is a strange behaviour.

Programs given with my ZX-IDE don't load anymore.
Emulator hangs after load.
When program is entered manually in emulator the statements are excepted and program can be saved and reload via tapemanager.
When trying to type NEW then error message 0/-2 appears and program is not wiped out.

Under ZX80 and 8k (or 4k, 2k) there are none of these problems.

Any idea ?

Where can I get the latest version ?
Are there any more differences between this version you posted here with ZXpand support ?

Thanks for clarifying.

Check that zxpand emulation is disabled, the ROM changes might have a bad effect on the tape routines, and the initialisation... I can't imagine why, though. I made some of the changes (but a long time ago now!) and Paul also contributed to the ROM. I believe the source is available.

It's quite possible that changes to the ZX81 code might have an ill effect on the '80 functioning. I can provide the updated EO source.

I Missed this updated version !
Well the sources could be intereseting, this update makes the AY sound work better..

There was a bug related to the setting of the coarse pitch register (i think). There is a lot of distortion in the emulation and I think perhaps there was a fix by Mike in progress which just never quire got finished. Possibly

Of course I'm happy to pass on the source code - what are you interested in particularly?

C

Well, to emulate some memory and i/o expansion for the zx81 and the Spectrum.
Also to try to port to Linux

Do they have borland c++ builder 5 on Linux? :S

That's strange. This emulator isn't 'installable'. In spite of this - it behaves like one.

I downloaded about 4 versions to check out if any of them will work with Timex Sinclair 2068 emulation. None does. They all go directly to Spectrum 48 emulation. Also this version.

What's strange, after turning-on, al the emulators go always to the last emulation machine I was using, despite the version I start. Although they're supposedly separate programs.

But all of them uses the same ini file! (ApplicationData\EightyOne\EightyOne.ini)

I was looking for the *.ini file but haven't found it in the emulator's catalogue.
Do You mean it resides in the System?
(Which I suspected so but couldn't localize it, heh).


__________EDIT______________
Yes indeed. You were right.
Thanks A LOT, Zsolt!
