Hi Guys: I'm Elmer
I'm sort of a Johnny-come-lately to this forum but I have a long history with the PCjr. I worked at IBM during the time of the big PCjr sales and literally everyone and his brother was getting or already had one or more jrs. During that period, both before and after I retired, I had a small business consisting almost exclusively of the jr. I did a lot of the mods and upgrades as well as repairs. I also worked closely with two gentlemen, Louie and Phil, who headed up the Eugene PCjr club. They single-handedly prolonged the service life of the Jr by at least 50%.

I don't have any PCjr stuff currently. I've moved several times and I guess I just shed some baggage along the way. Not that jr is baggage <Grin> All I have left are a bunch of NewsLetters and some technical manuals. Would be pleased to hear from any of that era.

For the record, I've already committed to help Elmer with his PCjr deficit. ;-0

Hi.

Would you happen to still have the technical details of making the PCJr graphics Tandy compatible? I have had no luck so far locating this on the net...

I don't have the Tandy instructions in hand, but I think I will have them in a day or two. If so, I'll send or post them. If my foggy memory is correct there isn't a need for any parts, just some cuts and jumpers. I will say at the outset though, that we, I or the forum owner, are not responsible for any damage incurred during the modification process.

If memory serves me correctly, my PCJr is out of warranty he he...
I really appreciate any help you can provide here.

OOps; Looks like I won't get the Tandy mod instructions anytime soon. I thought the guys from the one-time Eugene PCjr club would have a copy but they don't have one available either. Sorry. I'll keep looking.

Don't panic - I'm sure I have the instructions in paper form somewhere in the pile here ...

OK, I found the Tandy mod on page 9 of JrNewsletter for April '89. First, let me apologize. It does require a chip 74S86. It requires 1 cut and 3 adds. The 74S86 is piggybacked. If anyone is interested I can get it to you in whatever form. The 74S86 is $.29 at BG Micro. Yes, twenty nine cents. Don't know about shipping.

Great! Would you mind emailing the instructions to me to wmaalouli@comcast.net? Better yet maybe you can have Mike post them on this site for everybody's benefit.

Thanks for taking the time to look for them.
