Re: External board for SPonZY (and other ZX81 ROMs)

That look great. I also designed an internal board to shift between ROMs on the Lambda 8300 (Original ROM, Color ROM and ZX81 compatible ROM). However I have never tested it, as I have more ideas than time to implement them. (I need to get my ZX81 inside Minitel project finished, and I'm also workin...

Then they released a new ROM where a lot of routines were moved to other locations and they added support for color if you bought an extra Lambda Colou...

Re: ASM : Lambda speaker.

Hi. As you probably already found out, this URL has the best source for the Lambda 8300. problemkaputt.de/zxdocs.htm#lambda8300 There also exists a Lambda 8300 ROM disassemble scanned book in German. This however I cannot find at the moment. The info about TAP format sounds wrong. The Lambda 8300 fo...

Re: 2 cheap Lambda 8300 on eBay

Now there exists another very cheap Lambda 8300 on eBay, just for your information.

I am not associated with the sale.

I am interested in more people using this machine however.

Re: RAM Packs Alternatives?

Paul is correct in my opinion. The 80's edge connectors were terrible whereas the modern replacements are far better, one example is of those fitted to Charlie Robson's Zxpands. The white issue 6 I have from him has an edge connector that grips like a vice and like all my other spands suffers no wo...
