    3. Atari 5200

      The Atari 5200 was Atari's second cartridge-based game console. Based on the Atari 8-bit computer line and labeled the "SuperSystem", the 5200 was Atari's answer to growing competition in a market they were losing control over.

    5. Atari Lynx

      Lynx was Atari's first portable game system, and world's first color handheld. It was designed by Epyx and the engineers who created the Amiga. Ahead of its time, the Lynx sported a backlit color screen, stereo sound (in model 2) and an impressive range of games.

    6. Atari Jaguar

      Atari's last game console, the Atari Jaguar represented a huge leap in technology from previous offerings. Featuring a 64-bit architecture, the Jaguar had great potential, but its power was difficult to tap. Even then, many great games were released and the Jaguar has an avid fan base today.

    • You already know how to do poke and peek in Pascal, with the dual data type. Poke the VDP read address port to the VDP, then peek the VDP read data port from the VDP. If you want to write to VDP RAM or to VDP registers, you need to set the second or first bit in the address. Remember that UCSD Pascal can do bitwise logic functions by using the odd and ord functions. So you can do VDP_address := ord(odd(16384) or odd(your_address)); where both VDP_address and your_address are integers. That will set the VDP address for a write (which you don't need for GCHAR, of course). Also note that you'll need to create a swapbyte function, but there you can do a dual data type with an integer and a packed array[0..1] of byte, where byte is 0..255, to handle that.   Note that for this to work you need to manually set the code type to M_9900, since if it's M_PSEUDO then the code usually will be loaded in VDP RAM. If you then change the read address the PME will get lost about where the code is. The PME will only set the VDP read address when performing a jump. If you link in an assembly procedure into your Pascal program the linker will set the code type automatically, since assembly can't run from VDP RAM. But the compiler can't know which memory you'll access in a Pascal program, so there it's not automatic.
    • Ah! Great to know Dopey. I really would like to see the end results towards it.    You're welcome brother man. Glad to have you aboard and always a pleasure to read your postings that you share with us here on the Neo-Geo thread and throughout AtariAge. Can't wait to see your need title you purchase soon for your unit for sure.    Thinking of adding a Neo Geo Pocket Color to your collection Dopy? Such an underrated handheld unit with fantastic games to play. Maybe @shane857 and our friend @Reloaded85x would like to add that handheld to the collection as well.    Anthony...
    • So many great options. I think I'm going to take my time and think about them and what my goal is regarding the TI. Since I can already play most of the cartridges on my https://batocera.org/  system, as I said this would only be for running disk or cassette based games. If Classic99 can run those then the actual TI unit with PBox becomes nothing more than a nostalgia machine and without the room to have it on permanent display, I'll need to think about spending a few hundred bucks on modding the TI.   I'm going to open up and examine the PBox and test it. Let me see how well it works and if I can find a place for the box on the floor, that cable solution might be best depending on the condition of the PBox.   You all have been so great with all this excellent info. I so hope to meet some of you at the Chicago TI Faire if you are able to make the trek up (or down LOL) here in October!
    • +5.23V  but nevermind, I've tested 2 of my boards with it (my rock-solid, didn't need an R4 at all one, along with the 16MB stacked chip one - both running at 266MHz) and it passed the SAMS test on both up to 1MB where I switched off the machine.  I also ran some other SAMS tests and they all passed too.  This isn't unexpected though, there's a few things about this machine which makes me think it's only ever had limited use - so is practically in brand new condition...  These are the things I know about it:   1. It came from Texas and doesn't have the V2.2 GROMs. 2. The felt strip in the GROM port is totally clean, I even left it in, which BITD I never would have done. 3. There was a hand-written 'extra' page in the manuals, clearly written by a child (pencil & large letters) with notes about TI BASIC. 4. The power board switch was broken, which I've replaced, the small metal conductors were not inside the machine, I checked before 1st power-up. 5. I've measured the master clock speed and I get repeating values of 3.030 - 3.030 - 2.941 MHz - so it's running at almost exactly 3.0MHz average.   I'd say the early 80's kid had broken the switch early on (bad design in the beige model, using the switch itself as a stopper) and it's been in storage ever since.

    • Thanks, I always be trapped by this sort of things.  
    • While it wouldn't be easy to make an acrylic 1090XL case, it wouldn't be that hard either.  You can buy acrylic rod that is concave/convex.  You would just have to 'glue' the top piece and side pieces to them. All told, it would only require six large pieces for the top, sides, front, back, and bottom, and the two 'rolled' pieces for the top edges.  You'd also need some smaller pieces for support and alignment. Plus a great deal of measuring and patience.  While I do have an acrylic case for my 1088XEL, I don't think the 1090XL would look right without the brown front/top/sides and the big 'ATARI' written on the front.

    • Well the pokeymax project, as entered to abbuc, was intended to provide a low cost simple pokey replacement that supports all features in close to the original chip footprint.   Nowadays there is more spare IO exposed from the FPGA allowing various modules to be enabled at core synthesis time, mostly mapped in a standard software discoverable way. The modules available are: i) Pokey! ii) SID including decent filter for 6581 and 8580 as used in the C64. iii) YM2149 (PSG) as used in the ST iv) Covox v) Covox extension that can play samples from internal fpga ram, compressed using adpcm. Like Paula on the Amiga but uses its own memory due to system memory constraints. vi) PS2 keyboard support with fixed Atari key positional mapping (like the EclaireXL) vii) SPDIF output viii) Analog output ix) Flash support (needed for data for some of the above, otherwise used to store settings) There all take space, so you can decide what to enable based on the size of the FPGA you fit. The 'full' setup I used on the largest 10M16 (recommended) ones is quad pokey, dual sid, dual psg, covox with sample, spdif, analog, ps2   As to what v1-v4 bring, I'll post a small table shortly.      
    • Depending on how much room there is inside the touch pad, you could try and find membrane keypad the rich size and use that instead sitting it between the PCB and original membrane. Alternatively it may be possible to create a new PCB with surface mounted membrane switches that would replace the original PCB.
