RetroChallenge 2017/10

After a few years hiatus, I'll make another attempt at the RetroChallenge. Probably I'll get very little or nothing done but the lower I raise the bar, the more likely I will succeed with something.

This time I'll try to revisit some of the projects I've previously failed. In particular, I want to crack the code to serial comms in form of installing the Super Serial Card I bought for my Apple ][+ clone Basis 108 about a year ago but has rested on a side table in the hallway. I will also make another attempt to get a serial connection to my IBM 6151 RTPC. As a friend of mine recently obtained an Olivetti PC-1, we might both be working on our Italian PC's too.

Finally there are lots of repair and solder jobs, programming jobs and more that I can waste my time on when I get stuck with the already mentioned projects. Hopefully I'll make some progress on at least one of those.

After a busy week, I finally decided to get something done with the RetroChallenge on a late Saturday evening.

I intended to start with installing the Super Serial Card into my Basis 108 (Apple ][+ clone), but as it has a female 25-pin connector just like my existing serial cables, I need a M-M gender changer to get anything done.

Instead I put up my 6151 and while I didn't plug in the serial cable, I got to poke around the file system and with help from people at the #vc IRC channel, I learned commands for dosread and doswrite as well as minidisks.

If I indeed get it to work to read and write files to 5.25" floppy disks, that will be a secondary way of software transfer if the serial doesn't work out.

And yes, this system used to belong to a travel agency so about 1/3 of the total disk capacity is used up with software associated with booking trips. There may be additional unpartitioned space, that time will tell if I discover.
