Unlocking SWRAM

In EUG #6, S. Treasurer of Birmingham asks about an old Commodore disk drive. I have a C64C and 1541 MkII disk drive which isn't very helpful but a friend of mine used to own a Commodore Pet which did use the 8050 drive. According to him, the 8050 works through a GPIB (General Purpose Interface Bus) which operates according to the IEEE488 standard, and I believe this is used in a lot of industrial applications. A local Commodore User Group may be able to help more.

I recently purchased and fitted Slogger's Electron Expansion 2.0 (Actually 2.02) into my Plus 1 then puzzled a while as to why *RLOAD would not work with Pres' ADVANCED SIDEWAYS RAM. The Sideways RAM worked perfectly when I loaded ROM images with *ASR. But I found that, with *RLOAD, it is necessary to unlock the RAM and then relock it. Once I had done this, it worked well.

Can anyone let me have a copy of the instructions for the BBC disk copier CYKLONE?

I do agree with J.D. - Assembler or Assembly Language.

On caring for one's data recorder, may I add that is is good sense to clean the pinch wheel and capstan whenever the head is cleaned (or more often). Iron oxide can build up on the pinch wheel and it is possible for a spot to be deposited onto the tape. This explains why a tape that works well one time will not load the next. Quite frustrating but checking with a magnifying glass may enable one to find and remove the offending particle and render the tape readable again.

I do hope we are going to get listings on disk as well as the mag's articles. I was intrigued by the article on printing at full speed until I found that my printer only prints at 100 cps!

Finally, I'd like to know whether there has even been accounting and genelogical software written for the Elk and, if so, can I get hold of the programs? And finally finally, is there an expert out there on colour printing with the Okimate 20?

I think the newsletter is super, and much better value than the big glossies that don't support the Electron.
