I forgot to mention that with the program, it doesn't touch the memory between 0-FF otherwise it would overwrite itself.

Maybe the new emulator (DEmul) may work better?

Yes, but why should MPAA/RIAA get their half-assed ideas from it?

You can use your Super-80 to help you identify bad ram. First way: Type in E0 Type in C7. (note that the full stop is required) Type in G0 After about 5 secs, press the reset button. Now use the H command to examine memory, it should be filled with 0 and 1. Check out the 48k region with H8000 When you ran this little program, your screen may have filled with @A@A characters. You can display other memory pages in the same way by entering O F1 xx, for example, O F1 80 Press key to get back to normal. If this doesn't help, type in the program below which will fill memory with 55 and AA and reboot the computer. Type in E0 Type in 21 0 1 36 55 23 36 AA 2C 20 F8 24 7C FE C0 20 F2 C3 0 C0. (don't forget the full stop) Type in G0 After a moment, your screen will fill with UJUJ characters and then reboot. Then you use the Hxxxx or O F1 xx commands to examine the results. You might be able to determine a pattern of corrupt bits, and then be able to identify a faulty chip. Then, swap the chip with a good one and see if the fault moves (faulty chip) or stays (faulty socket).

Thanks!

The El-grafix kit consisted of 1x 2732 eprom, and 1x 74LS165 chip. The circuit diagram was in one of the books I brought over on my visit, the page is titled "Constructing the El Graphix Kit 4 Graphics Kit". The missing dot can only be caused by a bad socket on U23 or the 2513. U23 combines the outputs of the 2513 into a stream of dots, which appears on your monitor screen. If you're really sure you've done the memory mod properly, look for bad sockets on the RAM or the chips that address it. Have you tried using 32k or 48k of RAM to see if it changes anything?

Because it's just like an arcade game, press 5 to insert a "coin", then 1 to start the game. Usually Left-Ctrl to fire.

So is the problem solved?

Read ur PM. Yes please, better than lugging around piles of barely-readable paper! O F1 xx (where xx = page number)

The version you are trying to play is the UK version of TMNT. Therefore you will need to find and download tmnt.zip and tmntu.zip, and place these into your roms folder, which will be just under the mame32 executable. Then, start up mame32, press the F5 key to refresh the roms list, find your game in the list, and start playing!

The 8R5 requires lowercase characters, so don't plug it in until you've got lower case working. The Dick Smith board has an eprom containing 128 characters. The other 128 are simply reverse-video equivalents, and the other chips perform that function. The El Grafix is 256 unique characters, which mean a bigger eprom but the number of support chips is reduced. In my computer, you saw a special one-off, because by then the Dick Smith kit was no longer available. I'm not sure but I think it has the 128 normal characters and 128 reversed characters as if it was like the El Grafix. The Dick Smith kit plugged into 3 existing chip sockets which as you know will eventually damage them. It's better to just hard-wire something as it will be far more reliable. Whether you choose the Dick Smith or El Grafix set is up to you, as is the way you implement it. On my non-working Super-80, I have both eproms wired up, with a switch to choose which one I want to use.
