Perhaps you should upgrade to MyBIOS 4.9, that seems more compatible. It's on the atarimax-forum, MyIDE-][ Be sure not to run programs under MyBIOS that also use the OSRAM (C000-FFFF). That will surely crash the systems since it runs from that space. You can check on the emulator if it did, but also emulate MyIDE and see where it freezes... Later, Sijmen.

Already fixed 2 dead 800XL's :-)

Thanks for checking, I really got the values I mentioned, but now all is back to normal. I checked all drives just now with ".traceser on" and all act normal..... strange.... except IndusGT. IndusGT in the pulldown-list: -the only one I can select 288RPM,68k and it comes up with 47 cycle/byte or 38k. In Altirra 2.70 I get 68k (pokey divider $06). How do I upgrade the drive from 38k to 68k ?

Can you check the diskdrive emulation? I still see strange behavior when selecting drive-speeds. Generic 57k emulation runs at 30 clock/byte (in 2.70 this is 32) and indusGT does not like to do 68k.... Thanks :-)

Quick update, IndusGT now answers in 47 cycles/bit (38080 baud). Serial trace attached as spoiler: Real Indus_GT: Sorry, I opened the box and it's not a GT..... seems to be a Rana Sytems 1000.

I have a indus GT, got it years ago in a lot found in the neighborhood, but never tried it though...... My current UHSIO tries command $3F first. On no/bad reply it tries 3 baudrates, sending status commands with bit_7 set. Pokey deviders $10, $06, $00 aka XF551, IndusGT, Mr/|\ I'll download and try the update today. Perhaps I dig out the drive I have too and try on real hardware. Curious what and how the drive response. Later and thanks for the update! (P.S. Any plans on supporting external clock?)

I found some strange behavior while testing my UHSIO-routines on serial-IO. Using Altirra 2.80-test19 Took me a while to pinpoint the problem, but I found it...... Seems that the Indus-GT drive now works on 128k, bit_7 commands. Guess this is not correct. But a nice addition to the drive firmware. This emulates Mr-/|\ speed on my homebrew SIO2Arduino :-) Phaeron, how did you know this...?.... Later! Sijmen.

Thanks for the update :-) I still have to get used to the Device-tree. Quick report: I noticed slow CF/IDE-access, so I examined the hard disk setup box. The Solid-state (fast) is now un-ticked and the Spinning platter (slow) is ticked. I can change this, but after OK and do Settings again, its ticked slow again....

Not sure if this is to much off topic, but who knows. I upload it here for those who want to try it out. This is a modded REV2-OS I use to load tapes in Altirra 2.80 (due to the baudrate-bug in the original OS). It also supports UHSIO using the external clock. The picture is taken @ 175 kbaud, please disregard the read-speed, ANTIC/NMI are disabled so RTCLOCK does not count. The Write speed is a good measurement of how fast serial IO can go :-) Tape-speed can go up to 6000 baud / 25% gap-time without problem. I use a SIO2Arduino/SD for testing on the real hardware. Cheers, Sijmen.

Just upgraded from test11 to test15. Seems Altirra does not "see" MyIDE-][ inserted. Can't test further, since the MyBIOS software won't init due to this. On 2.70 and 2.80test11 all runs fine (X=01 when TRIG3 is pulled) Note: After adding devices, shift+F5 did not start the new config. Needed to tick reload roms on coldstart to make the changes work. Oh, can this be a sticky tick for the next altirra start? Back to 2.70 for now.

Hmm, ok, that is a pitty. I use it for MyIDE-][ to switch "cf-cards" or to run the system without medium. So for now, I guess better to stay on test11? (before the new HD-interfacing) Grtz, Sijmen.

Yeah, I build an SIO2Arduino myself and implemented some code to support .CAS files in c++ Then compiled and shot the new code in my little PCB. Works as a charm. :-) The extra code must be in multiple tabs of the SDRIVE-source. I can zip and upload my code, but the pin-layout is not the same as a stock Arduino-setup..... Also my c++ knowledge is very limited (hey, I'm an Atari-guy), so my patching of the code may be worth a laugh or two.... I also added 2 jumpers to select 600 or 850 baud playback (for standard OS) or 4800 baud with/without ultra short gaps for MyBIOS. So yes, it can be done.

Thanks for the update on Altirra and ATbasic :-) Soon you will change your mind to loving tapes and supporting them..... I did..... Regarding to the "Bruce Lee Problem" It still happens that the baudrate is incorrectly set and the bootloader is aborted. Perhaps this can help. In altirra 2.70 I get a pokey-divider of a steady $5BE, where in 2.80 it's a steady $5D4. Cheers, Sijmen.

Perhaps this helps: I did a debug on changes in AUDF4 Monitor: ba w AUDF4 Boot the tape and watch each block coming in. It sets $5D4 as baudrate on each block until..... Then on 1:06.7 it sets $1011, way off. Later!

Strange, here at about 1:07 the audio changes and you can hear that the pokey is out of rate. 2nd block of data, 4th buffer-load Altrirra 2.80-test8, XL PAL / 64K. But it seems random to me now too, sometimes it loads further, but most of the times not. Seems that the OS is failing to correctly detect baud-rate. Standard OS-rev2, nothing fancy with my work Other info: Mostly I have F1 pressed down to speed-up debugging, but that does not matter in this case. I have a Atom330based-PC, windows 7, to slow for >1.79 Mhz emulation.... I have some standard .CAS-files for testing and Bruce Lee is one of them, no particular reason. Later, Sijmen.

Hi Avery, While I was working on tape-support in MyBIOS, found something with Altirra. Bruce Lee (tape) does not load with the latest 2.80 beta. (2.70 it loads fine) System set to all patches OFF, standard REV_2 Operating System. File attached. Regards, Sijmen.

No, MyIDE-][ won't work on 400/800 computers. Bus-signals are different from XL/XE, so the hardware does not respond. Cheers, Sijmen.

Hi :-) This image is, for so far as I know, one of the good versions around on the internet. Most hacked disks have scrambled graphics at some point in the game. This one is perfect. I have this disk (pirate copy from Australia) and played it since my childhood..... Later! Sijmen. P.S. Leave the disk as MD, when it's SD the copy-protection kicks in and it won't load.

Well, actually, I have build me an Arduino SIO-to-MicroSD. I changed the code and it supports CAS files obeying the headers in the file. But.... using 2 jumpers you can set speed to 1x 2x 4x or 8x So no need for actual wave-files/FSK-coding, everybody uses digital files now-a-days. Also my Atarimax SIO-to-USB supports speed overwrite on CAS files. Making loading of tapes fun. That's why I decided to have tape-support on MyBIOS with acceleration. Anyhow, it's what you like to do. Cheers, Sijmen.

Thank you :-) Downloads peaked @ 25 December. Traffic to my homepage now is back to normal. Number of downloads of the game (.zip file) is almost 200, that is more then I ever expected. You are right about the response. Mostly the 4 player part makes it a fun game. (and a simple game to play) More 4 player paddle games next year? Hit "Like This" to respond..... Grtz, Sijmen.

Ok, I tried MyBIOS with the latest altirra to load .cas files set faster then 600 baud in the header. Like 1200 and 6000 baud. But somehow the speed-detection does not compute the correct speed due to emulation-error? (I believe you have my routines Phaeron) It listens to the direct serial-in-bit and counts 15.6 Khz intervals. Just bootup into basic (atari or altirra) and do cload. All patches disabled etc. I checked on the real hardware and that runs fine. Files attached. Only baudrate changed, not the gap-times (yet). Later, Sijmen.

Cool, I give MyBIOS a go at loading tapes @ 6000 baud :-) I love tapes, there are so many tapes and nobody knows what's on them..... Later!

Very nice, thanks for the info :-) Enjoy the festive season.

Ho Ho Ho... 80+ downloads in 24 hours. and an article on commodore.ninja ! I am delighted :-) http://commodore.ninja/lost-in-space-new-game-for-atari-8-bit-computers/

Merry Christmas to everyone! The game is uploaded and ready to be used :-) Enjoy. www.mr-atari.com/lost_in_space/
