Thanks for adding me to the list. (I think ) It's been a few years since I last visited, I tried to get to the events at Snibston, but I haven't been to the latest building.
It will be good to see if the Amstrad CPC Rom board I donated is working ok (I have an updated Rom with more games and an auto-start menu, if it's wanted)
I normally hang out on the Acorn Stardot forums, and you may have seen that I've been producing IDE interfaces for Archimedes era machines. I'll hopefully have a few boards with me to donate (again, if wanted), I should also have a few spare boards for sale if anyone is interested.
Link to the last batch I sold - https://stardot.org.uk/forums/viewtopic.php?f=8&t=16474 Find me on the day if interested.

Picked up an Amstrad DDI-1 and FD-1 dsk drive unit along with a ROM box for an Amstrad CPC whilst at Play Expo :)
Play Blackpool? Were they on the Rockrabilia stand? Wasn't the DDI-1 interface described as not working?

HARDWARE/SYSTEMS DISCUSSION / RCM big vectrex
« on: September 05, 2013, 10:38:37 PM »
Any one fancy having a go at building an updated deflection circuit from this web site for the vectrex with a big TV screen that has appeared at various RCM events?

http://www.e-basteln.de/asteroids/asteroids_monitor.html#deflection

The web site is talking about driving a vectrex tube from an asteroids board, but I assume that it should probably help going the other way to drive the big tv tube from the vectrex signals.

HARDWARE/SYSTEMS DISCUSSION / Re: CPC Romboard - any interest?

Would anybody be interested in a utility to put BASIC programs into ROM?

I'd be interested in taking a look at it. Not sure I can think of a use for it these days. Did it do any compression or just split it into 16K chunks (-loader overhead).

The romboard attaches to the expansion connector.

The amstrad had a similar mechanism for extra rom chips as the bbc, they could be up to 16K. It mainly got used for non-game software, utilities, editors etc. (protext, utopia and maxam from Arnor were the ones I always had plugged in).

The Amstrad supported up to 16 (8 on the 464) extra roms, Basic was in Rom 0 and Rom 7 was usually taken by the Disc Operating system. You could have more roms, but only 8(464) or 16(664,6128) would get initialised at startup.

My romboard uses a 256K flash device so it can support 16 roms (0 and 7 are mapped out in the GAL, so only 14 usable).

It was never intended as a mass-storage device, but some people have transferred a few games into ROM, they do little more than unpack themselves into RAM and start executing. Anything bigger than 16K has to be packed, or fit into multiple roms. (I just picked a few from here - http://www.cpcwiki.eu/index.php/ROM_Table)

A romboard to hold the supporting drivers and a SD card to hold the data would be a great solution.

Well, I got write support working. I had a few issues with timing to get right first.

It's very similar in concept to the MegaFlash, though it has been independantly developed.

The plan is to not need a read/write switch, I plan to use higher rom numbers to enable writing. So 0-15 will be read-only, but 64-79 (D6 set) would be writable.

Is the MegaFlash currently for sale, I couldn't see a obvious way to buy one.

HARDWARE/SYSTEMS DISCUSSION / CPC Romboard - any interest?
« on: May 11, 2012, 02:49:08 PM »
I've been planning to produce a romboard for the CPC for ages. I finally got round to producing a prototype. It's based around a 2Mb (512KB, so 16 roms) flash device. It should in theory be writable from the CPC, but I haven't got that bit working yet. It should also be possible to do a 4Mb version.

I plan to bring the prototype to the event tomorrow. Would anyone be interested in one if I decided to produce a pcb? No guarantee on timescales, as I need to get the write support working first.

(yes, the screenshot does show Bomb jack and Chuckie egg in ROM, just type |BJ1 or |EGG to play)

Got a game on a single disk to bring Saturday (unless it's already on the RCM Arc), game called Chaos, pretty decent version of Asteroids  :)

Spent many an hour playing that.

Are you still looking?

I've got an old clunker that I can bring to the event on the 17th.

All the bits are there, but it's completely disasembled, I had plans to clean it up but never got round to it.
