Home Page Forums MAME MAME New dumps

I thought it might be interesting to add a generic topic like this, where new ROM dumps (either for completely new systems or new dumps for existing ones) could be posted.

I'll start with the following:

Motorola PowerStack II boot ROM
Dumped from an Am29F040.

system specs:
- PowerPC 604e(? not sure since I didn't remove the heatsink, it's supposed to be a 200 MHz CPU)
- PCI Cirrus Logic CL-GD5446-HC-A video card without BIOS
- Symbios Logic 53C825A SCSI
- DEC 21140-AF network chip, DP83840 PHY
- Winbond W83C553F-G chipset
- M4T2B-BR12SH1 RTC
- Crystal CS4236 audio
- PC87308-IBN/VUL SuperIO
- 3xISA + 3xPCI, both on a riser card
Other chips (memory controller?):
- 94G0178/IBM98 PQ/19625A5797/JAPAN
- 20H2842/IBM 98/19651E2923/JAPAN

(I have a second machine of this type where I could dump the ROM for reference as well, might have a different one)

Good call on the topic. And nice find! A real live PReP machine - those are pretty rare

Since I have two of them (one without memory though) I would be willing to part with one. I'd even split the RAM evenly between both of them... However, they have a PROM password set (for which I have not yet found a way to bypass it -- no jumper or anything near the RTC)

I could also provide some high res mainboard pictures if that's of any help

...also, I'm getting pretty good at whipping up ad-hoc EPROM dumping hardware ^^

High res mainboard pictures are always good to have.

Looks like a cool machine ...

just found that re your password woes:

Okay, here's some stuff for the (hopefully distant? ;-) future. I raided the company's archive server and found a couple of SCSI HDD and tape drive firmware files:

https://www.dropbox.com/s/7uqyfzq4n5miq7w/HDD_Firmware.zip

Contains the following firmware blobs:

Also included are various OEM firmware files with special patches/fixes for NetApp systems (the first letter after the underscore in the filename specifies the OEM vendor. H=HP, S=Seagate, W=WD, etc.)

Interesting tidbit: Some of the firmware files contain references to something called
...which seems to be an embedded RTOS for the MCS-96 line of microcontrollers.

It's a bit sad that it doesn't go further back, I think most of that is post-2000 hardware, I hope someone will find it useful anyway. I remember some of these files were quite difficult to get, you had to have special ties to the technical support team etc.

I seem to recall HDDGuru.com having most of these as an attachment on their forums or something.

Nice! Yeah, those are all a bit newer than I'd like, but firmware dumps is always > no firmware dumps

While we're (or rather: you're ) thinking about emulating low level peripherals, how about emulating modems as well?

Here's something I had lying around for a while now.

ROM Dump (128kb) + High-res pictures of the Creatix SG2834 modem (28.8k baud, Data+FAX)

Manual (German only) here: http://www.creatix.de/support/download/gruppe7/SG2834DT.PDF

And an even older one: ROM Dump (32k) + pics of the Yakumo 24-F (2400 baud, data only)

I have found nothing about this one online, it's probably a no-name clone of some better known device.

The Creatix one uses a Conexant chipset for which datasheets are easily found. The Yakumo one uses a bit more obscure chips.

I updated the above ZIP files with datasheets that I found for the various chips used (couldn't find anything for the SC11046CN though)

Anyone want to take a stab at it? ;-)
