Re: Type in games?

There are Many books on Jr programs Check Ebay, most any 'basic' type book will work , you may have to tweak the basic program to fit the Jr, but usually not a problem. Also If you really want to experience the 'early Jr' get the Cassette recorder, and cable to save and load your programs, this is a...

Re: No mods, all original parts.

So nice to see a 'STOCK' Jr saved from the dumpster !!!
Especially like that the PCJr monitor is part of the package....

so many great games and software packages yet to be enjoyed...

Great job...

Re: Racore Pwr Supply Repair

Nicely done....... Is there an issue with noise, maybe let us know what the issue is! I have not heard of this, but it is not hard to believe the boards are noisy.... did it cause issues or gremlins that have been documented by the users ? even tho the Jr case does have a inside coating to capture t...

Re: NIB PCJR

Yes the good old Cassette recorder........ I think the radio shack recorder was a favorite back then.. TIDBIT: I read and article, back in the day long ago.... they talked about how the design to save 1's and 0's was (if memory serves me ) was 1200hz and 2400hz.... the gripe was that while the syste...

Racore Pwr Supply Repair

Hi Chuck, At some point I will probably upgrade my Quadram with the information you sent. I went back at the Quadram power supply and I could see the first band on the burnt resistor and it was orange. I measured the bad resistor and it measured 359 ohms so I thought maybe it only marginally change...

Re: New Monitor In Box

I bought a new 5153 with my New Eagle PC in '85... From what I remember it had a little better resolution than the Jr monitor, but heck back then COLOR computing was phenomenal... so I was not that critical... I will get aroundto unvboxing someday, when time permits and will do a side by side compar...

Re: PCJr Cluster Attachment

Yes I believe so, from what I remember, (foggy) it is a closed network with unique software for each JR to run.....

never seen one running but would be fun to watch two Jrs on an original network :)

Re: system goes bonkers during autoexec

the jr cases have a conductive coating, if you use an ohm meter you cantest this... Not sure why this would matter, but more so I am thinking the side case is keeping the JRIDE connector from properly seating and without the case it can plug in more deeply... can you see if this is a possible issue,...

Re: system goes bonkers during autoexec

Another thought, when I was using my DOM, it crashed 3 times and had to reformat and load files... Not sure why, but since I put a regular hard drive on, no problems, may be a speed timing issue, just a guess.. if you have a hard drive, that may be the answer. Note I was doing alot of Turbo Pascal a...

Re: system goes bonkers during autoexec

My first thought was the same as Rlumpy, try removing thr LPT side cars and putting the JRIDE directly next to the Jr case. let us know what happens then at boot up... Chuck Edit: I noticed you said in your last comment you put everthing back and it was still bad, what was the hardware config? Still...
