I purchased a Mega 4 ST when it came out, I took out my first loan to buy it with a megafile 30 hard drive. I sent a cashiers check to B&H photo and eventually got my computer. I also had the XT IBM emulator cartridge that I had to rob a bios chip from an old XT to get it running. It was my very favorite computer and I miss it. I still have all my floppies from back in the day. I hope to build a emulated or VM system to bring it back to life.

The internal expansion in the Mega is an VME Bus, and is compatible with (but not 100% the same as) the TT VME slots - There was an Official Atari 19" Monitor SM194, that natively displayed the 1280x960. Somewhere I read an article that said TOS detects an attached "super" HiRes Monitor via the DIN plug monitor connection (different resistance on one pin?), however ALL TOS ROMS contain the ability to use a 1280x960 (not just TT - I found that out by hacking the PCE Atari ST emulation sources, which uses TOS v1.00 by default) when used with the Nova Viking driver (by Ralf Zimmermann, available at the bottom of the Driver Software page, on the Atari Document Archive)

Nice and informative video! Haven't tried the actual version 2.4.1 of Hatari, but older versions were a bit tricky when it comes to acurate Falcon emulation. You have to fiddle around with the lower settings in System Options and especially CPU emulation parameters. Settings which work with 2.3x doesn't with newer 2.3x versions etc. Btw. the first thing to do when starting any emulation in Hatari is pressing AltGr+m for keeping the mouse cursor inside the ST screen!

Agree, great video! Thanks. For Hatari (version 1.2.0 at least) I didn't experience the same myself; It was/is excellent for Atari Falcon emulation (didn't need any special settings, it just worked great for all the scenarios I tried and had my Falcon 030 for comparison); I wanted it for running some of the great Demo's I had collected, it was a bit of a pain to have to break out the machine every time I wanted to hear the amazing tunes; Though still can't beat the audio on the original hardware IMO). The only caveat I personally found with setup was making sure I built the source code as a release (or I faced timing issues). Though, with the pre-built windows binary worked just great. Mind you, I am a Windows (7) user, so I can't speak for other platforms.

The 68000 could not work properly with a 68881/68882 coprocessor which were defined to be used with 68020/030. It was possible to use a coprocessor with the 68000 but it would have to handle the communication protocol manually. Atari proposed a coprocessor card for the Mega-ST called SFP-004 and proposed a API to use them in programs. The Mega-STE also had a socket for a 68881, but it would follow the same protocol as SFP-004. Normal programs that used $Fxxx coprocessor instructions do not work on 68000 CPU, that's why gembench and sysinfo do not show that there is a FPU. You can read all the gory details by googling "Atari SFP-004 by example"

So, I think Atari is right to desribe it as true color, as every pixel at 320x200 can be a unique color (e.g. 320x200=64,000). I also recall, as a developer, you specified the color's for the pallet using 24 bit values, 1 byte for each of R G B. So, whilst I cannot speak to how they implemented that and wether there was colour repeats in that range... I can say it was, to a consumer, a true color system. I did a basic check on the internet and the Wiki says the VIDEL chio was 18bit colour (Palette of 262,144 possible colours), so possibly there where colours it 'cheated'. Atari was a bit like that, with the whole 32 bits claim for a 16 bit bus (Not to mention the claim of the Jaguar being 64bits).

@@commodoreisnottheonlyfruit back in days "True Color" was video mode that does not have CLUT (Color Look Up Table) or Palette. It was mode where value of bytes represent a color and not position in palette. Apple called their modes like "Thousand of colors" and "Millions of colors" but I think that first time True Color was used is some graphic card for Mac that was able to display 24bit colors or 16 millions of colors. It is funny how these days we have 10bit per color or 30bit colors which we apply sticker "HDR" to these modes... Even in 90s I was quite surprised that Microsoft gave name "True Color" to 24bit mode since even then it was obvious that human eye can distinct more than 16 millions of colors.

I'm using hatari, but it doesn't emulate the MegaSTe properly. The MegaSTe had a 68010, but when setting the CPU to 68010, booting TOS 2.06 crashes. (I had a MegaSTe with built-in TOS 2.06 and it worked perfectly). -It's a good emulator, but I really wish the 68010 emulation would work (the only major difference is the RTD instruction, but I don't know if the loop-mode on the DBcc instructions and CPU cache would be emulated). [16MHz without cache would be approximately the same speed as 8MHz, but turning on CPU-cache almost doubles the speed when running 16MHz].

My debugger detects the 68010 by checking if the RTD instruction exists (and it also changes the VBR so it's invisible to any software trying to detect a debugger). On original ST/STF/STM/'STFM/STe/MegaST it reports 68000, on original MegaSTe it says 68010, on Falcon030 it says 68030. This is all by detecting the CPU from the CPUs available instructions. -Oh, and my debugger works in emulators today and when I change CPUs in the emulators, it still correctly detects the CPUs that are selected in Hatari.
