Seems like I found a cheap PCB distributor.
If I'd take 10 boards, the price for each would be 24?.
So if you're interested, E-Mail me and I might be able to have a run done. -
4116 and 4164 chipsI've just found the following supplier for 4116 and 4164 RAM chips. about $0.80 each.. not bad. [url]http://www.jameco.com/[/url] It's a US site. I…

Postage costs very reasonable and there PCB service is great. -

Looks interesting and useful. A minor modification to the PCB allows you to select the ROM bank with OUT 127, so matching other paged ROMs such as the ZXMMC+ and the Suffolk Science interface. -

It's my intention to ultimately make at least a small run of these boards. But it's a long way off yet :-) I doubt I'll be ready to get a PCB made until some time next year so don't hold your breath! -

Have you checked the MOS and BASIC ROMs? There are also a number of configuration jumpers on the keyboard - so a BBC might not start without a good connection to the keyboard PCB.
Fortunately, the ROMs generally are socketed on a BBC Micro. -

If I were in your shoes, I'd send a PM to DEATH - I know he's made a PCB that fits in the modulator's case, so you get comp out instead of UHF. -

And to me also - possibly compatible with the ZX81 given the shorter edge connector, although a close examination of the PCB would be needed to check that is the case. -
