Updates to the ZX81 Collection

Update History

I periodically update the site with new acquisitions. Please note, the rate has slowed down not due to lack of time/interest, but due to the fact that new titles are harder and harder (and more expensive) to get hold of.

If you have enjoyed the site, please consider a donation towards preservation of more items:

A * by an entry indicates that it had been identified as MIA from magazine sources prior to being added to the collection.

22/08/2016

Special thanks go to those generous people who have recently donated to the site, this will really help with the upkeep of the site and purchasing ever harder to get items.

Also thanks to Dick Berry who sent me the assembler source and listing for Home Money Manager.

06/04/2015

Major overhaul of the web site including:

09/11/2014

Minor update to the site to sign the JAR files for BASIC listings and the Java applet version of the EightyOne emulator. Also my email address has changed. I have a stack of 20 or so new tapes to add to the site when I get time.

For the JAR files it seems that you now need a properly signed JAR file to even run in a browser which means possibly paying hundreds of pounds a year to a trusted CA. I'm looking into options but would really like to keep the ability to run the programs within the web site so may be looking at ads or donations to fund the certificate.
