Perhaps you need to use a special SETUP utility for SMC network card. In it, allow the use of ROM and specify the starting ROM address. For example...

Tandy released Microsoft Flight Simulator for the Tandy 1000/1200/2000. The 1000/1200 version was in CGA graphics running at 4.77MHz but the T2K was...

Those .56 ohm resistors I ordered on ebay finally arrived. I wasted no time fitting a new resistor and the supply is working like a new one again.

I wouldn't have been as upset if he had just been honest. I once had a guy bid a generic 386 I was selling up to nearly $600, and then immediately...

Try reflowing the solder at some of the points. That might be your problem. Or, you might try checking if there's been some corrosion on the...

I think Neil from the Coco Crew is planning to take along his Tandy 1000 (EX / HX) with my PLUS-ISA/R adapters in it. Shame I cant attend too. :(

FYI there is already a USB to ISA adapter available. Dunno if it works with floppy controllers though.

I've broken and stripped both. But for me the norm, by far, has always been that Torx will cam out and strip, socket head will break. Or, the...

If anyone sees someone at the Tandy Assembly who has a Tandy Sensation on display and is possibly interested in selling it - send them my way please!...

I don't get throwing a Z80 and all the supporting hardware at the problem just to talk over a serial port; especially for cost sensitive...

Your red gun, on the CRT, is shorted. You'll need to replace the picture tube.

If he had just said "I've got to put money into PayPal, Please give me a day or 2" I'd believe him. It looks like he's hoping you will relist. I do...

I'm looking over the design, I will have to check out the S-100 ZFDC. So as I understand it the 16550 connects to the USB-to-Serial thing and an...

I wouldn't normally bother posting information about a buyer here, but this kid , micwal.vx2bql, deserves it. He won my auction for an IBM PC, then...

Thanks for confirming. I guess I can hook up the hard drive to a PC and check out the software. It appears I have CDs in two CD ROM drives as well....

The winning bidder on the PC flaked out, so it is available again. You can read all about it in the "Flakes to avoid on ebay" sticky.

I had the exact same epiphany and yep, backup worked. I should use that more often.

The FRU number is the same as the 20 MHz Model 80 planar so there should be zero difference between them.

Without knowing the architecture, I wasn't sure if this might be PS/2 based or possibly RISC (RS/6000) based. I guess we now know. Another weird...

The most common complaints I heard about HD disks failing with DD formats were from Mac users, especially with 400K drives. Whether those Mac users...

I use Keil's emulator to make bootable disks for myTRS-80 Model I and 4P. Have you tried to boot the physical floppy in the emulator? Why are you...

makes sense really. Why design a whole new mainboard when a stock one will do fine? The power connector is the same as my model 80. The number of...

Also, I just realised something! The power connector looks strikingly similar to the one used on a wire wrap test of the 5150 motherboard pictured...

It's huge! I forgot how big the model 80's were. I saw a guy chuck one off a balcony once about 20 years ago, I was furious with him because I wanted...

Right I'm doing that and it works for non-bootable disks like game disks, but it's not working for something that's bootable like LDOS.

I've done it previously, and it works fine. If you are using the Emulator and let's say you want to write the .DSK or .DMK image to a PHYSICAL...

I'll definitely check inside, but it seems to have developed a new problem in the mean time that makes me nervous to go poking around. I let it sit...

Thank you. This is actually the main board from an IBM 7785 better known as the "Mopar Diagnostic System". I have the "Hardware Maintenance...
