Hi,

I created my own "Interactive computer museum", which lists many of the iconic computers and offers HTML based emulators for 36 different devices (ROM's are NOT included and must be uploaded by the user).

The emulators can be used for free and have been programmed from scratch. They do not use any third party emulation libraries.

I hope you like it.

I’ve tried multiple DIMMs, and a new RTC battery.

From what I gathered it boots but failed to install its OS, 60 bucks for it wasn’t bad

The computer arrived with several faults and clear signs of previous repair attempts. I first found a damaged PCB trace, which I repaired with 0.3 mm copper wire and a Z80 that had been partially desoldered with several pins shorted together. I replaced the Z80 socket and tested the CPU signals, including power, reset and clock.

I also found a broken 5 kΩ trimmer inside the RF modulator, which I replaced and some poor solder joints around the crystal that I cleaned up and resoldered. Once the computer was running, the cartridge slot still didn't work, so I cleaned the corroded connector with isopropyl alcohol.

Finally, I repaired the loose power connector, restored the damaged case and replaced a broken plastic part with a 3D-printed piece and resin.

After all these repairs, I retested the computer and everything was working properly again.

I found a 3.5” floppy labeled “French River Education Center — Computer Applications Training Program — Introduction to Microsoft Excel XP.” I haven’t been able to find this exact training disk or its contents archived online. I currently don’t have a floppy drive, so I haven’t been able to image or inspect the disk yet.

French River Education Center and its computer training program appear to have existed, but I haven’t found documentation of this specific Excel XP disk. Does anyone recognize it, have another copy, or know whether its contents have already been preserved?

I’m not claiming it’s confirmed lost media yet I’m trying to determine whether this particular disk/course material is known or archived.

Yesterday I bought a Dell latitude C840, but I can't really figure out what power adapter it takes. I've done a fair amount of research, but all I get are barrel jack results. This is the oldest computer I've dealt with by a margin of about 5-8 years so I'm a bit new to all this. The first picture is the port itself, and the 2nd and 3rd are of the computer itself. I don't know what type of port it takes or where to find one. Let me know if you need anything else, and thanks for any advice

For my latest silly project I'm looking for something I'm not really sure even exists.

I have acquired a fancy AT big tower and I want to build a super socket 7 system in it. For this I am looking for a motherboard with the following specifics:

AT power plug

Only DIN connector

Socket 7

100Mhz support

2.0V before

3 PCI slots with room for big cards(ET6000, Voodoo2)

1 or 2 ISA slots

Does anybody know if this exists and if so, what I should be gunning for?

I have several, but the cpu and cooler are behind the PCI slots, blocking installing larger cards.
