Mike's PCjr Page

I already have a 40-pin wire wrap DIP socket on hand. The pins are too thick to seat in the PCjr's CPU socket. :( wet grind them down thinner with a dremel or rotary sander with a very fine grit. You might even consider doing it by hand with a decent sanding block. ... and trust me, don't try to do...

Now does the screen get corrupted like the real thing at the highest levels? (This would give me an incentive to try harder :lol: ). I don't know, I didn't test for it or plan for it -- though unlike pac-man for this to screw up you'd have to reach level 65536... since I used a word instead of a by...

I'm more referring to putting these: http://www.allelectronics.com/make-a-store/item/SHS-40/SINGLE-ROW-HEADER-1-X-40//1.html on a board one row off from a socket and then soldering across rows, or you put them next to female row headers like: http://www.allelectronics.com/make-a-store/item/SIP-40/40...

When I was doing stuff on perf-board and needed a pass-through I'd always just get a string of header pins, cut them to size and wire them in parallel to the socket I was going to use. You had to solder 'tight' and trim them down to get the socket in place over one of the rows of pins (dremel to fil...

1- I still have issues with joystick down despite proper calibration. The joystick works fine with other games. Anybody else has experienced that issue? Unable to recreate that here, could be a quirk in how the Jr. handles the joystick -- it's using the same code for left/right as it is up/down, so...

Ok, I made the assumption all voices were off when you start the sound -- apparently the Jr. starts out with the voices at a random low frequency setting. http://www.cutcodedown.com/retroGames/alphaEXE/PAKU1_34.RAR That SHOULD fix the buzzing on startup -- no guarantees though. If not, I'll set it u...

I'm going to re-read the section explaining what registers do what on the Jr as well. I made a few changes that may have gone a bit too far in trying to make it Jr. specific. -- edit -- http://www.cutcodedown.com/retroGames/alphaEXE/PAKU1_33.rar That's had a lot of the Jr. changes removed and instea...

Alright, if you come out with anything else, I won't be able to test it until tomorrow. I think my V20 died - I turn on the PCjr and I get a white screen and a buzzing noise. Same as when the CPU is removed. I think it's either that, or I've accidentally shorted something out. I've got a couple of ...

I grew up in NY, so when I choose to insult somebody they are going to know it. ;-0 I can see you and I rocking on the porch when someone drives up for directions. Me: <NH accent>"Ya cahn't geht theyah frum heeya..."</nh> You: <brooklyn>"Ya got a freaking problem with that?"</ny...

You know normally I wouldn't look too kindly on a flame war on this site. It's only a flame war when someone takes it personally - I'm not, I'm hoping you're not either... Of course being a backwoods New Englander I can insult you fifteen ways from sunday and not even be aware I'm doing it... There...
