[M100] Tandy Assembly 2019 Sep 27-29, 2019 in Springfield, OH

[Randall Kindig]

 
The response to Tandy Assembly has been fabulous and we’re ecstatic that we’re 
able to continue to offer this annual show to the vintage computer community 
and Radio Shack fans everywhere!


Tandy Assembly 2019 (the third iteration!) will take place on September 27th, 
28th & 29th 2019 in Springfield, Ohio.



We are very excited to announce that we are adding a day this year to Tandy 
Assembly and will be offering a new Friday feature called Tandy Tech Track!!  
This will be a selection of highly technical topics presented by some of the 
leading figures in the Tandy Radio Shack TRS-80 vintage computing community.



Exhibitor Registration is also now open, so if you have some cool Tandy stuff 
you want to show, please sign up!  While we have some speakers lined up as 
well, we still have openings for speakers to present interesting topics, so let 
us know if you have an interest.



We are planning to have an auction again this year as well, so please plan to 
bring any items you would be willing to donate to the event to offset the cost 
of producing it.  Any donations are much appreciated!

 

Finally, we would love to have you sponsor the event, if you are able to help 
out.  Sponsorships also help cover the costs of the show and help you advertise 
your hardware, software, business or service to vintage computer community.

Re: [M100] DVI Disk Formatting

[Randall Kindig]

Funny you should ask.  At Tandy Assembly (http://www.tandyassembly.com 
) last year I found the same issue with my 
single-drive DVI.  I can boot from a disk fine, but cannot format.  It just 
crunches forever when trying to format, then eventually fails.  I didn’t try 
writing to a disk.  A second DVI I had (but sold at the show) worked fine.

I’d love to know how to deal with that too.

Re: [M100] Tandy Assembly v2

[Randall Kindig]

Hi, Peter,

Not sure why you were surprised that I’m an officer of TA, but ok :)

Based on my recent conversation with Stewart, he’s committed to coming, so I 
don’t think it likely he’ll cancel.  He knows he’s the keynote speaker.  He 
told me during the interview I did with him for Floppy Days (floppydays.com 
) that the Model 100 was one of his personal favorite 
machines.  Even though the show didn’t cover Tandy machines a lot, he 
personally had a lot of the non-IBM-compatible machines over the years 
including Tandy ones and he really enjoyed them.

We do have other speakers set.  There are more on the Website now 
(http://www.tandyassembly.com).

thanks

Randy

Re: [M100] Ask a silly question

[Randall Kindig]

I currently have 2.  Until a few months ago I didn’t have any and had never 
seen a working unit.  Now I have 2 great working units.

I allows the M100/102 to display on a monitor rather than the small LCD.  It 
also gives it one or 2 disk drives.  They are great, if finicky.

Re: [M100] M100 issues

[Randall Kindig]

Thanks, Brian.

I’m an idiot.  I didn’t put the spacer in when I installed the REX.  It’s 
definitely not working.

I would love to get the correct cable for the T102.  How can I get the 2 parts?

[M100] M100 issues

[Randall Kindig]

What’s the deal with M100’s and getting good working ones!?  Right now I have 3 
bad M100’s; all with different issues:

- one shows garbage in the date area of the boot up screen, although the rest 
of the screen looks ok; the memory amount looks correct for a 32K machine, but 
it’s locked up upon boot up and won’t do anything

- one shows a weird memory amount; just over 16K.  If it were a 16K machine 
wouldn’t it have less than 16K on boot-up?  Additionally, when you go into 
BASIC, you get weird errors such as a syntax error when you use the NEW or RUN 
commands.

- one I just bought from someone on eBay who says he replaced the caps, so I 
thought it should be good for a good long while.  However, when I got it it had 
weird power-on issues.  I would have sent it back but then I put a REX in it to 
test and destroyed the option ROM area when I attempted to remove the REX (and 
I think I ruined the REX in the process as well).

So, I don’t have a good M100 to connect to either of my DVI’s via the cable I 
have.

I have a T102 that’s in tip-top shape, but don’t have a DVI cable for it and no 
one on this list seems to want to make one to sell to me (I can’t make one; I 
don’t care how easy you say it is to make one)

Any thoughts on the bad M100’s?  Have any of you seen these issues?  Anyone 
want to sell me a T102 DVI cable?

Thanks for your help.

Randy

[M100] DVI cable for M102

[Randall Kindig]

Does anyone have or makes the DVI cable that works with an M102?  I need one.

Randy

Re: [M100] DVI help

[Randall Kindig]

Brian, you are absolutely correct.  You sent me everything I possibly needed to 
understand how this should work and I managed to ignore some of it.

I really, really appreciate all your help.

I’m just pumped that both DVI’s work when for a while I thought neither did.

I will check the disk to see if has the 200 files on it, although I don’t have 
plans to get a T200.  I had one a few years ago and sold it.

Thanks again!

This worked perfectly, Brian!  I now have a backup system disk and both have 
the write-protect tab on them.

thanks!

By the way, the system is consistently booting now.  Just had to shake the dust 
off of it, I guess.

Still would like to see if I can get the other DVI box working.

My other question is around the boot disk.  I was sent 2 boot disks with the 
cable, but now only 1 seems to work.  I’m worried now only having one working 
disk.

How do I back it up?  Is there a way to do that with the DVI?  Can I create one 
in a different disk drive, like the drive in the TRS-80 Model 4P?

thanks

Re: [M100] DVI help

[Randall Kindig]

SUCCESS!

Per John’s suggestion (and was thinking the same thing when he suggested it) I 
now have a working system.  I started trying different combinations of 
DVI/M100/cable (of which I have 2 each).

DVI #2, M100 #2, Cable #2, no luck

So I swapped out M100 #2 (32K) for M100 #1 (24K/REX), and it worked!

It’s still a little finicky and doesn’t always work, but has worked multiple 
times now.  I don’t know if there’s anything I can do to “tune” it so it’s more 
consistent, but I”m pumped that I finally got it to work.

I had tried this M100/cable combination with DVI #1, so I’m wondering if 
there’s an issue with that DVI.  There also must be an issue of some sort with 
M100 #1 as the current DVI/cable setup didn’t work with that machine, but does 
with the other.

This sure seems like a finicky setup.  I would love to see a modern DVI 
replacement, perhaps with SD card for disk and video output, that would take up 
far less desk space and be more robust.

Thanks all!  Any other suggestions for troubleshooting why the M100 (#2) 
doesn’t work with this and also why DVI #1 doesn’t work with either M100 would 
be much appreciated.

Re: [M100] DVI help

[Randall Kindig]

That is correct, sir.  That’s exactly what’s happening with any combination of 
M100’s, cables, and DVI’s.

I’ve checked and rechecked the M100 end to make sure the pins are all in the 
sockets.  I’ve been paranoid about that.

Per the manual, the red line on the ribbon is on the right coming out of the 
M100.  If you try it the other way you have to twist the cable to get the DVI 
end of the cable into its slot correctly.

yes they do and I’m able to latch the cable end into the DVI.

Re: [M100] DVI help

[Randall Kindig]

appreciate the thoughts, John.  My question is: both drives?  That’s why I 
bought a second DVI; to see if there was a problem with the first one.

Also, it seems to me, and I could be totally in left field, that the fact that 
it boots to the Microsoft screen off the disk (both of them do this) would 
indicate that the drive is able to read the disk.  Also, upon reset of the M100 
the disk drive is supposed to light up and read DVI BASIC off the disk.  The 
drive light for either DVI does not do this.  It seems to me (again, I’m not an 
expert) that this would indicate a problem with the communication from the M100 
to the DVI.  However, I have 2 cables and 2 M100’s and it doesn’t work with 
either.

[M100] DVI help

[Randall Kindig]

Ok, I’m at my wit’s end here.  I have tried everything now and can’t get the 
DVI to work.

Here’s what I have:
- 2 M100’s, 1 with 24K and and 1 with 32K
- 2 very clean DVI boxes with a single drive
- 2 DVI to M100 cables
- 2 DVI boot disks

The cables have been tested by the guy who made them.  So have the boot disks 
for the DVI.  There are 2 boot disks for backup.

The M100’s both work great.

Here’s the steps I take:
- connect the cable from the M100 to the DVI.  I’ve double and triple-checked 
that the cable connections are solid and correct on both ends
- connect a monitor to the DVI
- turn on the monitor
- turn on the M100
- turn on the DVI without a disk
- when it asks for the disk, put it in and close the drive door
- the DVI boots to the Microsoft screen
- press RESET or CNTL-BREAK-RESET on the M100
- NOTHING HAPPENS

This is extremely frustrating.  I bought 2 of everything just to rule out where 
the issue could be and yet it makes no difference.

I just bought a new DVI, thinking that was the issue because I have 2 of all 
the other pieces and couldn’t get it to work.  It acts exactly the same way as 
the first DVI.

I’ll buy a beer for anyone who can help me figure out what’s happening here :)

thanks

Randy

Re: [M100] DVI issue

[Randall Kindig]

I didn’t know the cable was different for a 102.   The one I have is supposed 
to work for a 100/102/200.

I realized you had a 102 when I saw your break key was on the left.  Mine is 
more towards the middle.  You have to contort yourself like a Hindu goddess to 
press the CNTL, BREAK and RESET keys at the same time to cold boot.

Other than that, those are the steps I’ve been following.  No luck.

Re: [M100] DVI issue

[Randall Kindig]

hey, Brian,

thanks for the video.

The very first thing I noticed is that you plugged your cable into the RS-232 
port of your T102.

My cable has a chip on the end that plugs into the area next to the option ROM. 
 All the manuals that I’ve seen say that’s supposed to be the way it works.

Where did you get your cable?  Do you have a copy of your manual?

Re: [M100] DVI issue

[Randall Kindig]

Yes, of course, you’re correct.  I’m not getting to that point anyway.

I appreciate any help you can provide, Brian.

I’m following the steps in every manual I’ve found.  If I’m missing a step it’s 
certainly not obvious in the steps as I understand them.

I assumed that if that if the DVI booted to the Microsoft screen the drive and 
disk were good.  The issue is here that when the M100 is restarted nothing 
happens on the DVI.  No reaction at all.  The drive does not light up and does 
not attempt to read the disk to load BASIC.

[M100] DVI issue

[Randall Kindig]

hi, all,

I’m having an issue with my DVI box and was hoping someone on this list could 
point me in the right direction or had suggestions.

I have a really clean DVI I recently purchased.  The picture showed that it 
booted to the initial screen off of the boot disk, so I assumed the drive and 
the DVI itself were good.  The seller did not misrepresent it.  They showed it 
booting to the initial screen and did not test it further with an M100 and DVI 
cable.

I got a cable and boot disks (with backup disk as well) from someone else that 
was tested to be good.

When I hooked up the M100 and cable to the DVI, it indeed booted off of the 
disk.  At that point, you reset the M100 and it’s then supposed to load further 
software off the disk and the screen of the M100 is now routed to the monitor, 
with more columns and rows.

However, when I reset the M100 nothing happens.  It doesn’t matter whether I 
soft reset or hard reset.

To verify this setup further, I bought a second M100 and tried it to take that 
out of the equation.  No difference.

I then got a second cable from the gentlemen who was making the cables to make 
sure the cable wasn’t the issue.  No difference.

I can only conclude that there’s some inside the DVI box.  The tests point to 
the fact that all other parts of the chain are fine: M100, cable, disks, disk 
drive.

Does anyone have any experience with the DVI box?  I have the electronic form 
of the service manual, but it gets into electronic troubleshooting for which I 
don’t have the skills or experience.

Any help would be much appreciated.

[M100] DVI cable

[Randall Kindig]

Does anyone have a cable for connecting the M100 to the DVI box (for composite 
monitor hook-up and disk drives)?

Does anyone have information for making one?  I know that Ian Mavric was 
looking into making a cable for this great M100 accessory, but I thought I 
would ask the list.

thanks

Randy

Re: [M100] Model T upgrades

[Randall Kindig]

Guys, I’m very encouraged by this discussion.  While I have both a REX (from 
the last run that Zippster did) and NADSBox (I was lucky enough to get one from 
someone about a year ago) I would most certainly order another new run NADSBox 
and a WOOLLY.  Heck, I would buy one of anything that came out!

Just wanted you to know that there definitely is interest out there.  The Model 
100 is a great little machine and these things just make it even more useful

Re: [M100] M100 upgrades

[Randall Kindig]

thank you Peter and Kurt.  I’m thinking of getting the REX and an 8K RAM.  
Sounds reasonably priced and a terrific upgrade.  Not sure I want to spend the 
$200 for the NADS box although it sounds awesome.
