I've got some questions about this system I'm hoping some of you might be able to answer:
1.) Does anyone have a scan of the Telegames Personal Arcade manual, or any paperwork associated with the DINA/Personal Arcade?
2.) The system's video processor is a TMS9918A. I'm pretty sure mine got cooked at some point (when I first power the system on, I get a black screen with a white static line or two across the middle; eventually, you can make out garbled graphics, and even more eventually, the video display will be correct...sometimes). I have some spare TI99/4a systems I could cannibalize another 9918A from, and I have a semi-working Colecovision I could pull a 9928A out of. I want to do a video mod (actually I have to; I tried to retune the RF output to Channel 3 and I think I broke the adjustor...it's stuck somewhere between Channel 6 and Channel 7 now). Would you recommend the 9918A or 9928A for this?
3.) Could the DINA's Taiwanese BIOS be swapped out for Colecovision one? I think I'd just leave it the way it is, but I'm curious. I thought the green splash screen with the Chinese logo* was odd at first, but it's kind of grown on me.
4.) Is it possible to mod the Pause button to work with Colecovision cartridges? Or would that require additional components, as with the Atari 2600 Pause Kit?
5.) There are two spaces on the board near the BIOS/ROM where it looks like ICs were designed/intended to be placed, but were not. I read somewhere that some Colecovision controller ICs could go there, allowing full use of the Colecovision controller (and, presumably, the Roller and Super Action Controllers as well) and keypad. Can anyone confirm this?
6.) What the heck is the expansion port for? Apparently no expansion devices for either the Colecovision or SG-1000 are compatible with it. Was Bit Corp. planning to release an expansion for the DINA themselves?
*I understand this to read "Chuang Zao Zhe 50," which was the original name of the DINA console as conceived by Bit Corp.
