any luck ... with HyperTerminal?

The BLU manual says:

NOTE: HyperTerminal won't work for bootstrapping as it mangles CR/LF combinations!

Which seems sufficiently specific that it might do an xmodem transfer ok, but it could also mean it was a non-starter and so wasn't considered worth testing -- sorry I don't recall.

Given no progress in either direction, I'd guess it is a handshaking issue.

In any case, trying an alternative may be informative.

Good luck!

edit:

This post from Ray implies that HyperTerminal could work, but doesn't confirm he tested it.

edit 2:

In a 2007-02-01 email exchange with Ray there is this comment:

HyperTerminal rejects the data UNLESS you wait until a couple of timeout failures pass; whence it switches from CRC to checksum; if you start sending then it works ok.

It may be that was before BLU understood CRC, but it seems worth trying.

Has anyone ever had any luck dumping diskettes and transferring them with HyperTerminal? I replaced my SCC today and while all the replacements I got all now work fine for simply bashing on the keyboard to make text pop out of either end, I cannot either end to see an Xmodem transfer.


For the curious: I suspect my original SCC is one of those infamous faulty chips sold as NOS - there's no evidence of sanding, but the legs were all suspiciously tinned. Oh well, I have a bunch of very pretty ceramic and gold SCCs now, so I'm happy.

Another interesting fact: the Desktop Calendar is assigned to tool number 140. I wonder if this has any significance or if this was just a completely arbitrary choice by Videx?

And for anyone who's curious, it looks like the original copy was serialized to the Lisa with S/N 69942.

Okay, I just deserialized the image and removed the bytes that enable serialization to begin with, so just use the copy attached to this post and it should work great!

Trying it out for the first time, this version is definitely a lot more feature-rich than the other Desktop Calendar!

Thanks so much for uploading this!

So a while ago I asked if anyone had a copy of Videx Desktop Calendar archived as it was posted to LisaList1 way back when and then lost. Bitsavers does have a copy of something called "DESKTOP CALENDAR 9/9" that I thought was Videx Desktop Calendar.

Not long after that question, I found an original copy of Videx Desktop Calendar on eBay for cheap, so I picked it up because I thought it'd be a cool trophy piece to have an original copy, even though we already have a good dump of the disk from someone else - or so I thought.

Tonight, I started reformatting my Lisa because the attendees at VCF absolutely trashed my X/Profile's filesystem. Whoops. While reloading software I thought "Hey, let's pop in this Videx disk just to make sure my Sony drive is still OK." Then I noticed the icons on the disk were completely different to the icons in the "DESKTOP CALENDAR 9/9" disk image - the icons are wayyyyy more detailed. (Calendar Comparison.png: DESKTOP CALENDAR 9/9 is the top set, Videx is the bottom set.)

So of course I had to immediately stop what I was doing and grabbed my BLU CF card and started to dump the disk... and now I think my Zilog SCC is dead. It'll receive bytes no problem, but only spews out garbage on the transmit side. Oh well, I have a 603e Mac clone running 8.6 that still works great, so I just dumped the disk there instead.

Unfortunately while it appears the disk dumped okay the software was copy protected and LisaEm with the special Serial FF00 set won't get past it. Someone can get past it I'm sure but it's late and I'm tired now. Attached is a copy of the disk image for someone to try and bust!

Here's an old ad for Videx Desktop Calendar on Applefritter. It seems the Videx calendar is way more feature-rich than DESKTOP CALENDAR 9/9 is. It's like your Outlook calendar, but in 1984... https://www.applefritter.com/content/videx-lisa-desktop-calendar-ad

I've had this happen more times than I care to admit...

Same here. I eventually got so tired of it that I just bridged the pins of both switches with a piece of wire and now there's nothing to worry about!

This problem could be as simple as the covers not being fully closed and the interlocks are not closed.

My Lisa 2/10 no longer powers up. No response anywhere when power button is depressed. Is it ok to power up the PS on the bench without anything connected (no load) to it?

No response may be due to problems other than the PSU.

Try removing the I/O Board and reassembling (without it); most Lisa's will power up immediately if power is connected and the I/O board is missing. If it does power up, then the problem is likely on the I/O Board. If it does not, then checking the PSU outside the Lisa would be a good step.

But, the PSU won't just start up outside the Lisa when plugged in.

If you plug it in with nothing connected, you should be able to measure 5.6V or so at the +5 Standby pin. If it isn't there, then I'd guess the fuse is blown, and you may be able to see some obviously damaged parts inside.

To get the PSU to start up, you'll need a test fixture that:

• Connects +5 Sense to +5.
  
• Has a modest load from +12 to Ground
  
• Has a modest load from +5 to Ground
  
• Has a switch or jumper to connect +5 Standby to ON (connect to turn on, disconnect to turn off)
  

Some terminal connections (double check against one of the PSU schematics, eg: Lisa PSU - improved Rev J Schematic). One side of the connector is numeric, the other alphabetic which skips some letters such as I and O.

• +5 Sense = N
  
• +5V = M,11, 12.
  
• +12V =  K,L,9,10
  
• Ground = 13,14,15,16,17,18,P,R,S,T,U,V
  
• +5 Standby = 20
  
• ON = X
  

One of the test fixtures I have used has a 1 ohm @ 50W load on +5 and a 15 ohms @ 15 watts load on +12. These are certainly more of a load than is necessary to just power it up, but a minimum load may conceal the ripple that can result from bad filter caps.
