oh, and this isn't me. I just had a really bad experience with them where they "lost" 2 of the 5 Priam disk drives I bought from them, so I guess local pickup in Rochester NY is a good thing. On 7/18/18 4:01 PM, Al Kossow via cctalk wrote: > > https://www.ebay.com/itm/292646012304 > > local pi

SMUFDDV4@1104

I asked this in the GOTEK thread but I think it got lost in the chatter. Does any of this apply to the equivalent devices with the board labeled SMUFDDV4@1104? I have a few of them and would love to make them work with non-PCs as well. bill

I would think that any interpreted BASIC would do this or for that matter any interpreted language except maybe for APL which is pretty much written with tokens anyway.  One other exception I can think of is perl  which is stored as source text.  Saving in tokenized form was good for to reasons
