Your Grand daughter can play ZORK I online: https://textadventures.co.uk/games/view/5zyoqrsugeopel3ffhz_vq/zork A rubber mat saying 'Welcome to Zork!' lies by the door. >take mat Taken. >eat mat I don't think that the welcome mat would agree with you. Edit: Zork 2 and 3 are available here. http://www.play.vg/games/153-Zork0Trilogy.html

Also. . . If you find that all the chips won't fit on Mini-ITX, then Flex ATX is the next size up. Size is 229mm x 191mm And a lot of the cases that fit an ITX will also house a Flex ATX case (but not all obviously!) Best of luck with the project.

Regarding the layout -- and this is just a suggestion, as I've never created a complex PCB myself. Since you are using the mini-ITX we can assume that anyone using the board will put it into an ITX case of their choice. The size of the External PBI and SIO cause the problem that they take up most of the space along the back of the PCB. [Those not familiar with mini-ITX should know that where Michael has put the PBI and SIO are the back and would always be accessible on a ITX case. So. . . that means that the 2 joystick ports and the PS2 ports would not be accessible unless you open up the case. It seems to me that one should put the ports that would get the most plugging and unplugging action at the back (always accessible). And in my opinion, the joystick ports would get a lot of the plugging and unplugging action (removed when not in use). Whereas the SIO port would have something constantly plugged in. [Legacy floppy drive or printer.] Or at least one could always have the floppy drive connected and route the cable out the front or the side of the case (may require modifying the case). One final comment/ question: could you stack the 2 joystick ports? And stack the 2 PS2 ports? similar to the image in this link? I realize it would be harder to do but would give you more space to work with along the edges of the board. https://www.google.com/imgres?imgurl=http%3A%2F%2Ftechreport.com%2Fr.x%2Fam3-chipsets%2F790fx-ports.jpg&imgrefurl=http%3A%2F%2Ftechreport.com%2Freview%2F17061%2Fhigh-end-socket-am3-chipsets-under-the-microscope%2F2&docid=MPSfMSOw_0RyMM&tbnid=DOlHlAEJOH1zCM%3A&vet=1&w=600&h=255&bih=662&biw=1366&q=stacked%20ps2%20ports&ved=0ahUKEwjnu82rzNnRAhVl0oMKHdDDDNsQMwhEKB4wHg&iact=mrc&uact=8

Looks like a great project! Very exciting Since ITX form factor is new to some - note that the mounting hole placement is critical to being able to mount the board in these cases. Please refer to http://formfactors.org/developer%5Cspecs%5Cmini_itx_spec_V1_1.pdf and see pages 8-9 form the mounting hole placement. Some Mini-ITX cases to consider for this board. http://www.newegg.com/Product/Product.aspx?Item=N82E16811163287 Small case with a handle for portability. http://www.newegg.com/Product/Product.aspx?Item=9SIA66Z3NV0593 Gold case with plenty of space inside and ATX power supply. Many people already have the ATX power supply. https://www.newegg.com/Product/Product.aspx?Item=9SIA66Z3NV0591 Same as above but in silver. I think some people could get really creative here and give this silver case a 600XL/800XL theme to it.

The Return of Heracles had to be my favorite. Combination adventure/combat and if you knew some Greek mythology, it helped you move along the storyline quicker. I would love to play it again.

I was reminded of this thread when I read http://www.theregister.co.uk/2013/11/06/why_your_kids_cant_program_part_1/ on The Register website (which everyone should read regularly). A good read -- many of you will enjoy it -- and some will disagree I am sure.

A few suggestions: Judging from the size of the microcontroller, it looks like the board is about 3 inches by 3 inches. Would it be possible to bring this down to 2" x 3" (while still including room for the buttons)? Based on some empty space, it looks like it can be shrunk down some. However, I have never designed a PCB, so I don't know anything about this. You mention debugging. Do you think it needs much? If so, I might wire it up on a breadboard as you suggested. But, having other "projects" as I mentioned in the PM, might be a while before I do this. Otherwise, it looks great! I think some people would want to put in a project box -- which is why I suggested a bit smaller. A "simple" way of creating a project box would be to have a "top" and "bottom" of clear acrylic. I saw a Raspberry Pi encased in a simple box (see image) which, looks nice, yet is probably not too expensive. Others -- please chime in, even if you have enough SIO devices (Just an example of a clean looking, finished project) I guess buttons would either need to be mounted (making it more complex) or be at the very edge of the board.

Hi Don, Happy New Year! Knowing what little I know about experimenting on the Arduino, I think I can use any 28-pin Arduino compatible chip with your board, right? I have an extra ATMega328 that I ordered with my last order from Jameco. I would be interested in an extra PCB and the bill of materials or an order of parts if you can get enough people for discounted components. Are you located in the US? I am in North Carolina. Thanks.

atari8warez and candle, Thanks for the replies. I will put the cable back to the way I had it in picture 1, then continue on. Thanks again!

Sorry to dig up an old thread, but I know other people are still purchasing U1MB and installing these. I purchased the U1MB and the adapter board for the original when Ultimate 1MB board first was introduced by Candle, and am now installing it. I have a socketed 65XE, so I didn't need to desolder the MMU or the OS ROM. My question pertains to the cable on the OS ROM. It seems to me that Pin 1 should be as pictured in my first image. [both ends of Pin 1 are labeled in yellow.] However, if one refers to the image on page 12 of http://www.atari8war...nstallation.pdf it seems that the pins are different. Picture 2 shows me reversing the cable -- I realize Pin 1 on the system board must always be Pin 1, but I was labeling this picture as if the red line on the ribbon cable always indicates pin 1. Since I have the adapter board from Lenore, I didn't need to modify the ribbon cable to the MMU. I still need to add the last 4 wires, so I won't be finishing this right now -- thus I figured I would consult the Experts and make sure I'm not doing this wrong. Thanks for the help from any recent installers or from candle!! Hitch

[This project is not mine, just something I found that others may be interested in...] Yesterday I found this Kickstarter project http://www.kickstart...hem-al?ref=live When finished, it will play POKEY music, sounds, as well as sounds from other 8-bit consoles that we need not mention here. The kickstarter campaign is actually done, but if you are interested in purchasing one, go to: http://store.gadgetf...&products_id=59 and there is a pre-order link with more information. Development is not yet done, but I asked Jack, the developer about POKEY and he said that it was one of the two most popular add-ins, so he is working on that. To quote his email Anyway, for those that are interested in that sort of thing....

Interesting, I agree. For those out there that have never seen the Ultima V disks that Rob is referring to....what state are they in? Is it only maps and straight data? Waiting to hear more of this story..... Hitchcock
