Any way of dumping the EPROM contents to see if there are any text strings that might give a clue? Also there's what looks like a bit of text along the top of the card that I can't make out, does that give any hints?placa1_PCB_Text.jpg I'm at work right now, but I'm assuming you're talking about …

Thanks for the feedback. I won't have a chance to take pictures of the PC until later today or tomorrow, but the place where I salvaged it from is near the local hospital - maybe that system was used to drive some medical equipment of sorts? Sadly the HDD, 3.5'' floppy and PSU were taken out before …

Good evening all. Here's an 8bit ISA card that came with a computer rescued from the scrapyard that I'm really curious about. placa1.jpg IMG_20210713_230217-01.jpeg IMG_20210713_230210-01.jpeg I'll post more info about the computer it came with, but so far it appears to be a 486 overdrive with a …

I've got it fully working at last. How can I dump the BIOS and where should I send it to? Easiest way to do this is with a software utility - one like Navrátil System Information (NSSI 0.60). It has an option to save your BIOS ROM contents. Just make sure that, in your BIOS settings, Shadow RAM is …

If you're in the Lisbon area, there's a computer shop with a nice museum in the Odivelas area. https://goo.gl/maps/BnxYDSDcKP1ycLwq7 There's also a full-fledged Spectrum-dedicated museum in Cantanhede, catchily called Load"". https://g.page/museu-load-zx-spectrum?share

In short: no. I know some nice British folk, and I know there are a bunch of British assholes. But then again, that can be said about just any country/nationality/ethnicity/whatever. About soccer, I don't enjoy it. So I was glad when my country was eliminated, that lowered the talk about it to a …

Running Stunts/4DS on a 386SX40 was surprisingly fluid, as my computer at the time was a 486SX25 and I was expecting it to by jerky. Was pleasantly surprised!

You're right, it's this one : http://www.win3x.org/uh19/motherboard/show/5482 But I think it's still an ECS 8517, just not the same rev. Can you turn it on and show us the POST string (and eventually make a BIOS dump and share it with us ?) It's working now - I (wrongly) assumed the pin 1 of the …

More precisely, it's an ECS 8517 http://www.win3x.org/uh19/motherboard/show/6803 Hello. If you're refering to the board I got, no it's not - the one you mentioned has one 8-bit slot, and the one I have has none - they're all 16-bit. Luckybob seems to have nailed it right, though...
