That was a pretty good deal for a Model M, actually - they're fantastic keyboards, and they're still in current production. From Unicomp; these are not copies but just re-branded, made on the same tooling as the originals. Current production ones are more than $50, so, not too bad all in all. …

Hehe you cant compare this. When I remember 100 g of chocolate cost 0,49 DM in the 80s ... now its 1,29€ ;-) Therefore it would be around 1000€. Which is still quite cheap for an up to date PC with Harddisk and Monitor. Scanned the Manual. TCI Trident Computer Inc. Oct 01 1987 Suntac TCI EMS-286.pdf …

Yes 10mbit coaxial. This is a nice card as it has Jumpers and you dont have to mess with PNP configuration or to find the manufacturers config tool. For connection of Coax to a TP network I recently got a converter (5€ incl. shipment). I also tried to install a 2nd Coax-PCI-card in my Windows 7 64 …

Thanks both for your hints! I inspected the boards, but I noticed nothing unusual. Expected to see some dark traces on a larger area. But I didnt dare to disassemble all boards for inspection. Smell..it was not sweet. Also not like burnt plastic. More like burnt electronic, dont know how to describe …

Good advice! Best to not tempt Murphy's law. I generally try to make my repairs look...well, invisible. But my German OCD is the reason for this. A functional repair is certainly more valuable than a failed attempt at a pretty one. Care must also be taken not to lift that pad. Lots of flux and …

Dear all, I am happy to still own the Monitor of my very first Computer. Its a Thomson 4570 EGA Monitor from around 1987. I also have its Manual and the wiring diagrams. After a storage period of more than 10 years I tried to power it on again about one year ago. First it displayed a good picture. …

It should work without BIOS setting. Is the message "Loading DOS..." still displayed? After the initial screen with the memory check there maybe a switch of display mode. Did you try to readjust your monitor? Have seen this with my ET3000. After connecting another monitor the image was there..

Exactly, XTIDE Universal BIOS. Its 8k in size for its Basic version. Maybe you can also use something else, dont know what is available. I assume your Board can only access the data on the Original chips, so your EEPROM with additional space might be useless. Maybe the single 8k chips contains this …

You dont need ISA. XTIDE has a feature to boot from a virtual drive via the serial port, but I never tried it. I think its a good way to move forward with a BIOS extension. I did not fully understand yet whre the message ""Boot MS-DOS from EEPROM"" appears? Is it displayed on the screen? Did you …

Nice story and nice computer! I am not familiar with this hardware. If you dont get the floppy running...what other connectors do you have (serial, parallel..?). Is there a socket for an option ROM? Maybe you can use XT-IDE with a serial drive?

That's only a minor problem assuming they weren't damaged from the coolers being roughly removed. Are any of them interesting? Also other intersting parts in the box. Unfortunately he removed all coolers from the graphics cards, therefore useless :dead: Hmmm I dont think so. They are looking intact …
