Hello John:
Yes, I described how to test the microprocessor within a Portable Disk Drive (TPPD1 or TPPD2) without any mounted diskette or reliance upon the mechanical condition of the disk drive. The URL is below. [ http://www.club100.org/library/doc/testtdd.html ] is the link to the Club 100 website, Documentation, "Test Portable Disk Drive via TELCOM".

Hogerhuis Sent: Thursday, January 14, 2016 18:41 To: Model 100 Discussion Subject: [M100] TPDD2 Data cable pinout? I don't really remember but I don't think anything happens when you turn on the drive. It just sits there. Ron Wiesen may be able to help you... I have a vague recollection of some short BASIC code to send a test command and get a response. I know I've seen it and I thought it was Ron's. You there Ron? -- John.
