MAME cabinet, system upgrade part 1

The Esprimo P5916

Heh, just a little over month gone by, since I announced the hardware of my MAME project complete and I already find myself working on it again. But.. as it happens, I managed to get my hands on a Core2Duo PC (E6320 CPU @ 1.86GHz) for next to nothing. Decent performance upgrade and possibly the end of motherboard-related-video-problems?? Sure, sign me up!

The PC I got is a Fujitsu Esprimo 5916 and summing up its specs, well.. Most importantly, the mobo has a serial port! Never thought I’d say this, but it’s actually a much needed legacy feature, as the spinner I have is built around a serial mouse. Little less upgrades this way, perhaps :).

C64 keyboard, wrapping up

Busy “Bee” me, project complete! Not much further work stage photos to present (thanks to yours truly forgetting to pack the camera along), so let’s roll with some photos of the completed keyboard.

Nice contrast between the case and the keyboard.

Ports gone!

C64 keyboard, chop it

Lemming / Orange was kind enough to donate me a Keyrah he no longer had use for. Figured it might be a good subject for a round 2 of ‘playing with epoxy‘.. This time around though, I decided to that I’ll skip the sorry attempts at heating/forming plastic :)

Lower half cut into two and a piece sliced out.

MAME cabinet, software

Finally dropping fiddling with the video hardware, I was able to move on to the actual emulator configuration. This task also swiftly turned out a far more bigger one than I had expected.  Maybe just a little bit of history repeating to make my day with this project? Whereas it seemed, at a glance, something in the lines of “install frontend + emulator + ROMs, do a bit of config“, actually getting down to it proved out more something like “install frontend and get stuck in a myriad of config options and fine-tuning“. Despite having worked on the configuration quite a lot, it’s still pretty much “in progress”. But since the cabinet is up and running, I figured I might just as well do this post. Nailing things down to the last bit of detail isn’t of importance here anyway.

ZXDSL 931WII hacking

The stock 931WII

Recently, I decided to upgrade my ADSL subscription to VDSL, and the deal included a ZTE ZXDSL 931WII CPE box (VDSL2 modem + NAT + WLAN AP). Attached with the box were instructions stating that configuration settings could be managed from a private web page provided by the ISP. And was one able to do so? Of course not. Much to my annoyance, it also turned out that all ‘outside the box’ local configuration had been disabled in the firmware (no response to LAN http, ssh or telnet). So, a quick call to the ISP helpdesk:

Hi! I upgraded to blablabla and would like to configure it but there’s nothing else on the remote admin panel than a save -button”

“Ok let me check”

“It doesn’t accept any http or telnet connections to the local admin interface either..”

“What would you like to configure?”

“Well you know, the usual stuff people configure on their home router; static IPs, port forwarding, admin password etc..”

“Hmm well I can see that implementing the feature is pending, but I can check details about this with someone. Is it ok if I text you shortly? Kthxbye!” *CLICK*

Some minutes later, there’s a text on my mobile saying “There is no known schedule for adding remote configurability for the current firmware at this time”. W-T-F and thanks a fucking bunch! :D

Seriously: Do they think that I’m going to run this box in my home without having any access to feature configuration?

Sure I can understand that, given the increasingly technical times we live in, the need might arise for the ISP to be able to remotely check the CPE configuration of some less-technically-inclined subscriber using their ACS server. But why-oh-why disable all local configuration options? Surely, the option of configuring the hardware could be kept available to those who wish to do so?

Not happy with the situation at all, I decided it was time to take a look whether local configuration could be performed from inside the box.. I’d rather have a bit of my own fun with the box instead of paying xx€ for queuing +15 minutes on the phone just to be walked through a “Did you check cable connections” check list (or whatever). Should my “playtime” result with a bricked box, no problem. The ISP can then have the box back accompanied with a “the lights just went out” fault description and I’ll go buy something more decent :)
