We know. Esp 20+ year old things with plastic tabs holding it together. We did battery mitigation before I got here, I don't want to tell them...

Plastic isn't going to last forever, that's a given. But it varies in durability, longevity. Here I am staring at any number of plastic vintage puter...

Actually, the bore in the keyboard is still OK because the bad screw couldn't get far enough into it to destroy it. I think it just pushed the...

Rebadging old chips has gotten to be an art in the far East. Rather than repainting the top, it's simply easier to abrade the markings and then...

Probably a brass insert--that's good. Get out your tap set and thread all the rest to agree then get some matching screws. With the shades drawn...

It's materials choice that is so often short sighted. I used to own a Volvo 940 turbo-brick. Great car; good mileage and lots of room,...

:D The chassis is plastic, but right at the bottom of the channel there is some black material, hard to tell what it is, that the screw...

TopBench says 8086. Yes it's an ebay purchase, a semi-local US seller. If this was rebadged they did a very good job of it, as I said the chip...

Hi lgiscl, Thanks for pointing out that issue with the manual. I didn't realize that happened. I'll send them a complete copy this weekend so we...

I found it easier to tweak settings from the PC while watching the unobstructed display. But, more importantly, you cannot save a truly complete...

Hard to tell from only one example, but it would suggest that there is a problem with PA3 from the G8 PIA, the G9 '145 or the connection between them...

>>> Updates to follow soon. We wait with interest... Dave

Plastic isn't always a bad thing. It's cheap ultra mass produced plastic that's the problem I'm guessing. To go off topic a bit, the upper intake...

It's probably a Chinese brushing scam. Chinese sellers acquire information about people in the US and send them random packages so they can make fake...

I read the article, but it gives no indication of what you're using for your serial interface.

I have one too and love it. Curious what you thought was so essential about interfacing it serially with the PC. I did update the firmware on mine...

While waiting for the Dell unit, I've taken some stainless steel wire and sheet brass and bodged a couple of brackets onto the old fan assembly. ...

If you have more CPU and memory than bandwidth, you could also get fancy and take a cue from the video compression people--just transmit the...

Let me guess--you bought it on eBay. :) Probably a relabeled 8086. Timings should be substantially different. You can always go into DEBUG...

PS/2 drives do have a "disk changed" signal. Clearly it's not making its way to the planar.

One might put the shoe on the other foot and ask why computer manufacturers persisted so long in mixing SAE and metric fasteners in the same box. ...

I see. I puted back the RLL controller inside of the tandy and it's ST-225 and it now all works as it was before.

There isn't a RLL controller anymore I changed the port as it was suggested before your comment (now sits at 280, I tried other ports that should...

Something like the Jelly of the month club?

Or it could be dust clogging something up. Did you notice the second time if the disk access light came on. It probably did not. The system...

" What happened with Computer Reset and the remnants of the Houston Computer Museum wasn't fun to follow. A few personal observations as both...
