FOR SALE / WANTED / M5 Multi II - New version of Sord M5 multicart
« on: October 13, 2016, 10:32:59 PM »
How many years has it been? Too many. Anyhow, I've finally done what I should have done years ago and re-designed the cart.

The original was hard to build and overly complex. The new version has simplified the construction and the user experience. Game selection is by menu, no DIP switches or button presses  8)  Just switch on, press a key and you're away.

Carts come with all the currently available (working) ROM images as well as BASICs -I and -G, which benefit from an additional 32K of RAM.

Carts are lovingly hand built to order. Price is £40. UK postage £3 1st class signed for. I'll ship anywhere, but I insist on tracked/signed for service when sending overseas.

Facebook usually gets the first pictures over at the Sord Computers group.

PM me for further details!

I've made a kind-of 'norton commander' for managing files on your zxpand.

You can grab the binary and source over at the ZX81 forums: http://www.sinclairzxworld.com/zxpand-commander-v1-0-t956.html-st=0&sk=t&sd=a

With this program you can:

Browse directories and files
Execute programs
Create subdirectories
Delete files and empty subdirectories
Rename files and directories
Move and copy files

Hope you find it useful!

HARDWARE/SYSTEMS DISCUSSION / 32X auto-region switch
« on: September 18, 2012, 10:34:19 AM »
I've been thinking about this for a long time and seeing as the Sega box was out I got to work.

I have both a PAL and an NTSC 32X and the PAL one only works with my unmodified Megadrive 1. My modded MD1 - which has a hacked version of Seb's Saturn switchless region changer in it - produces glitches when producing PAL output. I don't know if it's because of the hacks or if there's simply a core incompatibility. The modded MD is a very early model with the AUX port so perhaps this is significant anyhow I digress.

The MD cart socket has H and V sync signals. Scoping around shows these as TTL level signals and woohoo! the vsync signal changes in response to jumper changes without a reset. I wrote a little PIC program to time the sync pulses and output either 5V or 0V to the region select pin on the appropriate 32X chip.

So now my 32Xs automatically adapt to whatever machine they're plugged into (I guess, I don't have a US genny - does anyone have a spare I can have/borrow?) without flipping switches or any of that nonsense. Flipping refresh rates on the modded MD also switches the 32x.

Now all I have to do is work out if I can run the 32x without an external power supply by tapping off the MD's rails on the cartridge slot. No-one seems to have done this so I wonder if it's even possible...

HARDWARE/SYSTEMS DISCUSSION / Dreamcast & SD card adapters
« on: September 04, 2012, 02:12:32 PM »
I'm sure I saw a topic on here relating to this subject but I can't find it now, so here goes anyway:

What are the options for booting dreamcast games from SD card, and has anyone got any experience of this??

Ta!

I've heard that this may be a useful addition to a collection; someone over at the Einstein forums has had some success with it. Has anyone had a play?

HARDWARE/SYSTEMS DISCUSSION / DivIDE resets speccy :(
« on: June 12, 2012, 02:17:57 PM »
Hi all,

I'm looking at a rubber key Speccy 48k/divide combo owned by a colleague. Pressing the button results in the machine resetting, with no DiVide splash shown. Straight to the sinclair banner, no messing. I've tried the interface  on my trusty Spectrum+ and it works fine. So the problem is definitely with the original 48k which otherwise works fine.

Where should I start looking, d'you think?

Ta!

GENERAL RETRO CHIT CHAT / Please help identify my joystick!
« on: February 10, 2012, 11:23:05 AM »
Matron!

It's a competition pro. Black. With a 15 pin D on the end. I did think it was the BBC micro version, except (as far as I can tell) the pinout is different, and it's not cream. I also don't think that it's a PC stick according to the wiring.

There is a picture of its internals here:

Can anyone think of any other computer system that used a 15 way D as its analogue input?

Of course there's always a possibility that this was a user hack...

Thanks!

GAMING . . . / Best game to use with Sidewinder Precision Pro joystick?
« on: February 01, 2012, 01:19:37 PM »
I've modded my stick to connect via USB and now I want to try it out - If you're not familiar with the device it has a stick which twists, pov hat and a dial-like thingy with about 170 degree movement.

I'm sure there are plently of flight sims which might do the trick but I was thinking something more mame-like. Arcadey, y'know.

The z rotation and slider produce a linear value. Aah sod it - here's a picture of the properties page...

GENERAL RETRO CHIT CHAT / hidkeys 0 - mame panel 100
« on: December 11, 2011, 09:21:50 PM »
So if you've been following my efforts on FB you'll have seen I made a usb twin joystick adapter based on the brilliant v-usb stack. It didn't track multiple keypresses so it was useless for anything other than very awkward typing.

The best thing about the v-usb code however is that it's been used by _loads_ of projects and they're all open source. I found this one:

http://vusb.wikidot.com/project:mamepanel

which was nice. It does exactly what I wanted and as the hardware for all the projects is pretty similar it was a simple case of re-flashing the controller's program. I made a couple of changes to the firmware's controller mapping and POW!

When you plug it in the PC recognises two HID joysticks with 8 buttons each. No drivers required. Go to the game controller control panel and there they are. MAME recognises them, and once joysticks are enabled for a particular game you can configure the controls and away you go.

Awesome stuff!

RCM GAMING EVENTS - OPEN DAYS 2011 / See you on the Saturday I hope..!
« on: November 16, 2011, 02:58:31 PM »
Hi all,

I'm hoping to get to see you all on the 26th! One thing I'd like to do is make sure people's ZXpands have up-to date firmware. I'll be bringing some V5 EPROMs with me and if you'd like to upgrade I'll be happy to swap your old 'prom for a new one.

If you're thinking of using your ZXpand with a ZX80 then there are a couple of changes needed, one of which is to the memory decoder GAL, so I'll have a supply of those too. Again, either just bring your board or the chips and I'll do a swaperoo.

It's possible I could bring some AY boards - would that be good for anyone?

Charlie
