--------------------------------- REQUEST REAL DOS DISKS: I now do the Australian
and New Zealand arm of the REQUEST REAL DOS DISKS feature of the US
www.trs-80.com web site. If you have
an old TRS-80 and need a DOS disk to see if it still works, drop me a line
and I'll supply a DOS disk for the cost of postage. (Applies to Model 1, 3 and 4 DOSes - Model 2/12/16 maybe in the future, but if you
have one of these 8" systems by all means contact me to source DOS boot
disks from like-minded individuals.) --------------------------------- REPAIRS TO TRS-80s: (Added on 11 Feb 2012) Some of you may have
noticed I'm on the list of TRS-80 repairers on Ira's www.trs-80.com web site
and I've had a good response from people who have sent me their
machines. Of the 3 people who have
contacted me and sent 4 systems (as at 11th Feb, 2011) only one system (a
Model 1 keyboard unit) was too far gone and needed a motherboard
replacement. This is a pretty good hit/miss
ratio considering the age and history of the equipment in question. Some people have asked me what's actually
involved. 1. First you email me and
tell me what's wrong, I may request a screen photo before taking a look so I
have some idea of the complexity of the problem. 2. You send me the
computer and I set it up on my workbench and check it for obvious problems
like corroded wires, moisture damage, physical damage etc. I power the machine up and spend up to an
hour with a logic probe, CRO, and multi-meter to try to determine why the
machine doesn't work. I don't charge
for this service, its part of the quoting process. (If I quote on repair and you think its to
high/not worthwhile, then I'll just send your computer back for the cost of
postage.) 3. I quote you for the
repair and state how long I think it will take and which parts and how much
those parts will be. The quote is not
fixed, I may find other parts needs replacing once I get to work on the
machine proper, or find it takes longer (or sometimes shorter) amount of time
to complete the job. On occasion I
find a machine that even if I think I can fix it, in might find later that
its just too far gone and can't fix it.
In this instance I just tell you No Charge, can't fix it. Due to the age of the systems this does
happen from time to time. 4. The computer is
repaired, set on a 24-hour burn in on my workbench then advised the total
cost with itemisation of parts replaced. Your computer is sent back in the
same packaging you sent it to me in. 5. I warranty all my work
for 90 days but in reality it only covers the parts I replaced, so lets say I
replaced a 74LS00, 74LS367, 4116 and a 2012 in a Model 1, if those parts fail
then I'll replace them. The age of
TRS-80 systems means it possible that other original components could fail
but in reality old TRS-80s are very robust machines and often my repaired
machines hang in their for many, many years.
(My own personal Model III, for example, needed a chip replaced in
1990, and the computer is still in use, virtually every week, and not had a
problem in the past 22 years.) -------------------------------- REPLACEMENT CHANGE-OVER ASSEMBLIES: (Added on 11 Feb 2012) Sometimes when a part is
too far gone to be repaired, then I suggest a change-over part which has been
rigorously tested by me, as a quick solution to get a non-working TRS-80 up
and running. Here are some: * Model 1 motherboard 16K
Level II $250 inc labour. * Model III motherboard
48K $200 inc labour. * Model 4 non-gate array
motherboard 64K $200 inc. labour * Model 4 and 4D
gate-array motherboard 64K $250 inc. labour * Model 4P motherboard
64K $275 inc. labour * Tandy TRS-80 Model 2000
motherboard 256K $250 inc. labour * Hard drive internal HDD
- $250 inc labour (These are the common ones,
less common ones include: M3/4/4P HT video board ($100), FDC ($100), disk
drives ($125ea), Expansion Interface board 32K ($200), Model III power supply
($65ea) and Model 4 power supply ($95). Keyboards generally can be repaired
if they are ALPS type, and I charge $10 per keyswitch.) -------------------------------- TALKING ABOUT MY REPAIR WORK...: (Added on 11 Feb 2012) "Literally blew up
my TRS-80 when I connected the power to my video port - "As a TRS-80
enthusiast, Ian’s TRS-80 restoration service has been utilised by me on
numerous occasions with outstanding success on each time. This Australian TRS-80 recycler has the
skills & knowledge to repair your TRS-80, my experience with Ian comes
highly recommended." - John
Benson, Lismore NSW. -------------------------------- PACKING AND SENDING TRS-80 COMPUTERS: There has been some discussion
on Vintage Computer Forums about the dangers of shipping poorly packed
TRS-80s - they rarely arrive in one piece if not packed properly, and this is
especially so for the Model III and 4.
Some years ago CN80 published articles on how to properly pack these
computers for transportation. Click
the links below to read the articles in their entirety before sending me your
equipment for repairs or sending machines to each other: http://ianmav.customer.netspace.net.au/trs80/Shipping
Your Computer.pdf and http://ianmav.customer.netspace.net.au/trs80/ShippingDiagram.jpg -------------------------------- NOTES ON TRS-80s FOR SALE: I now sell three
different types of TRS-80 Model I/III/4, and thought I'd take a moment to
explain the differences: 1. AUSTRALIAN DELIVERY:
these are computers originally sold by Tandy Electronics chain in Australia
and are 240V/50Hz operation, and the sticker underneath states "Tandy
Electronics" and 240V/50Hz operation.
On Model III and 4 they have a removable IEC (mains) power cord. 2. US DELIVERY: these are
computers originally sold by Radio Shack and Computer Centre chain in the
United States and are 120V/60Hz operation, and the sticker underneath states
"Radio Shack" and 120V/60Hz.
On Model III, 4, and 4D the power cord is built in and dangles out the
back - this is normal. These machines
require a cheap 120V Step-Down converter to run, and they work perfectly
well. (For other details on US
Delivery machines, see the section below "WHY BUY AN AMERICAN
COMPUTER?" 3. AUSTRALIANISED-US
DELIVERY: these are 120V US computers which I have converted internally to 240V
operation and have an Australian plug on the end of the usual US dangly power
cord. A sticker under the computer
states that the computer is now for 240V use.
They don't require a 120V Step-Down transformer. These
Australianised-US computers will be listed in with the Australian computers,
but clearly marked as such. -------------------------------- NEED MORE PICTURES? I usually only put 1 or
sometimes 2 pictures of up the systems I am selling, even when I eBay them I
only put 1 or 2 photos BUT that's not to say I don't have many more pics of
each system. If you are interested in
a machine and need more photos, by all means ask. I can normally email you photos within 12 hours
of asking. -Ian. AUSTRALIAN TRS-80s FOR SALE: -------------------------------- FOR SALE: (Added on 8th April 2012) TRS-80 Model 4

----------------------------- FOR SALE: (Added 6th May 2012) NEW 12VCMP31 green screen CRT for Model I/III/4 Is your CRT in your Model
III or 4 TRS-80 worn out? Is it full of screen burn or did you break it when
you opened your machine and don't know where to source a new one? Or are you
sick of the regular B&W television-grade tube in your TRS-80 Model 1, III
or US M4? Just arrived from the
USA, I have currently on hand NOS P31 green screen CRTs which are easy to
install, see my video: http://www.youtube.com/watch?v=9sMXSMSsCZU They work great in a
Model III or 4, and work reasonably well in a Model 1 (this is due mainly to
the very archaic video circuitry in the Model 1 monitor). If you are in Melbourne I
can even install them for a flat fee of $45 while you wait... $150ea with 90 days
warranty.
How about an amber
picture tube? I can also
source amber CRTs if you
really want a different looking TRS-80... (allow a few months delivery, I
ship goods out of the USA twice yearly - EMAIL me to place your orders). TRS-80s with Amber CRTs fitted:

4Ps become very yellow with age, and this one is no exception but
that's why I'm selling it CHEAP. Even
though its CHEAP, it still passed all my stringent tests I do to sell a good
used system. This 4P has the
traditional arrow-key arrangement rather than the later model clustered arrow
keys - so if you like to play those old TRS-80 games this computer is
great! $250 includes 90 day warranty (just like Tandy used to

from people enquiring about non-running TRS-80s they wish to buy for a repair/restoration
project or just for a supply of parts to keep their machines up and
running. Previously I've not really
entertained this idea because I'd always presumed people would want a fully
working machine they can simply take out of the box, plug in and use. From time to time I'm going to put a machine in this
WHERE-IS-AS-IS area. It will be
complete (unless noted) and a description of any noted faults and then its up
to you if you want to gamble that you can make use of it. IN MANY CASES I COULD PROBABLY JUST FIX THE
MACHINE MYSELF BUT HAVE DETERMINED THAT THE TIME (possibly 10+ HOURS) IT
WOULD TAKE ME TO DIAGNOSE AND FIX THE FAULT IS NOT WORTH MY WHILE SO THAT IS
WHY I'M LETTING IT GO. So you've been
warned, the computers which appear in this section are non-runners, aimed at
those with the technical expertise to repair them." - Ian. -----------------------------

capacities -------------------------------------------- WHY BUY AN AMERICAN COMPUTER? As you can see from this
web site, I carry a lot of equipment imported from the USA. Why would you be interested in an American
unit? Basically the rules of supply
and demand mean that I can get them more readily in the US than in Australia,
and I can sell them cheaper than comparable Australian units. "Australian Delivery" TRS-80s
(mean TRS-80s manufactured in Fort Worth, TX to Tandy Australia / InterTAN specs) sold in relatively small numbers compared
to their American brothers and are very hard for me to locate in Australia
and are usually in poor (ie. high mileage) state
requiring complete rebuilds by me in order to sell them. US units, on the other hand, have often had
much less use and need less work by me to make them ready to sell, so I can
ask less for them. Australia delivery
machines should probably be left unmodified for posterity and I encourage anyone
buying a TRS-80 to modify it with the myriad of customisations out there to
consider attacking a US machine with your soldering irons rather than local
machines. But that's just my opinion. Of course US machines can in some cases be
upgraded to Australian 240V power supplies for a cost, but I have found in my
experience that those cheap 240-120V Step Down converters you can buy on eBay
work very well. My own workshop has a
$29 300W step down connected to a TRS-80 Line Filter (basically a US 8-outlet
power board) which is connected to my Model 4D, a hard drive, and whichever
other US TRS-80s I happen to be working on with no sign of the capacity of
the cheap Step Down being overloaded. DIFFERENCES BETWEEN US and AUSTRALIAN TRS-80s: Model I: US power
supplies are smaller and fit inside the Expansion Interface, Australian power
supplies are larger and don't fit in the EI. Model I: some machines
(well, most) have an additional cable between the KB and EI making the
keyboard and EI a matched pair. The mod
is called the DIN-cable mod. Model III: virtually the
same machine in both countries except US models are fitted with twin 120V
power supplies. RS232 was always an
option on all Model IIIs. Model 4: non-gate-array
machines have B&W monitors, and keyboards by Maxi-Switch, optional RS232,
as well as a 120V power supply. By
contrast Australian non-gate-array M4s had green phosphor monitors, ALPS
keyboard, RS232 as standard, and a 240V power supply. Model 4: Gate-array
machines are virtually the same in either country, both came with a green
phosphor monitor and a cheaper membrane action keyboard, and 120V power
supply. RS232 is standard because its
built onto the motherboard now. Tandy Model 4D: never
sold in Australia but as the last and best TRS-80 it has a very high quality
monitor, ALPS keyboard, double sided disk drives, and naturally a 120V power
supply. Model 4P: non-gate-array
4Ps have a B&W monitor, but are otherwise the same as Australian non-gate
4Ps, other than the 120V power supply. Model 4P: gate-array 4Ps
in both US and Australian models feature a green phosphor monitor but
otherwise are the same machine except for the 120V power supply in the US
versions. Hard drives: TRS-80 hard
drives have a Model 4 power supply installed and an A/C powered cooling fan;
120V for the US market and 240V for the Australian market. Care must be taken to replace the fan with
a 240V one if upgrading the power supply. Color Computer 1 and 2: I never sell US Coco 1s and 2s
because they are NTSC only and don't work properly on Australian PAL
TVs. However if someone really does
want one I'm happy to do the import. Color Computer 3: I may import these occasionally because
they can be used with a monitor, but remember, like the CC1 and 2, the CC3
won't work properly on Australian PAL TVs. Next update I'll talk more about the
"other" TRS-80s Model II/12/16/16B/6000 and Tandy TRS-80 Model 2000
and Tandy 1000s and how they differ between Australia and their US
brothers. --------------------------------------------- BOOK, MANUAL, CATALOG and MAGAZINE SALE: Common books: Basic Faster and Better
