Hi! Bought some stuff at a local vintage computer meetup a week ago. Among it were the already well known VIC-Switch, and the rather known PET-Switch / MBS-100. I also bought a black "PET" datasette with black keys. I can report that the PET Switch uses 4066 analogue switches in the client modules. This came with two different client modules, one laying flat on the table and one standing up. The client modules has different number of 4066's. The horisontal one has iirc a total of 12 4066's each piggy backed in pairs. The vertical one has iirc a total of 9 4066's pigged back in triplets. Escpecially the vertical one gives a sense of being a prototype. This PET-Switch has 9 LED's, presumably for 8 client stations and one power LED. In the ads for it I've seen 16 clients mentioned and no separate LED per client. Is mine a rare version? The thing that seems really rare though is a SCIP, a device which hooks up to the IEEE-488 bus and gives a serial port, according to the ads configurable for current loop or RS232. It uses an 8748 microcontroller, and has a large row of transistors to drive the IEEE bus. (Probably cheaper to do it that way than using those specific IEEE-488 transciever chips). Do anyone have any information about the SCIP? -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination. (> <) Come join the dark side. /_|_\ We have cookies.
