WISH LISTS OF TANDY TRS-80 ITEMS

(Added 22nd Dec, 2012)

It's come to my attention from a few of my regulars that a lot of people watch this site looking for newly-listed items hoping that something they have been looking for for a long time shows up.While this may happen, its also possible that I already have the item on hand and just have never thought it list it here.I have literally hundreds of small items, software, spare parts and accessories for TRS-80s, not just what is listed here.In fact if I were to try to list everything on this site and update it as things come in and go out it would be more than a full-time job.

So by all means, if you are after some weird accessory for your Model III or a special game tape for your Coco, or anything in between, then ask me.If I don't have it I may suggest you go on a waiting list here for said item, you never know when I might see it in my travels.This also goes for systems not listed on this site and hard drives.

NOTES ON SHIPPING TO OTHER COUNTRIES

(Added 24th June, 2012)

More and more people from outside Australia have been finding my little web site here and have been asking me about the possibility of sending my items to them in other countries?The short answer is YES, anything is possible.

 

The longer answer is that please bear in mind that Australia is a long l-o-n-g way away from most other countries (except perhaps New Zealand) and so shipping even small items will cost a considerable amount.Blame Australia Post, or Fedex, or UPS or whoever you choose to use - they set the shipping rates not me - I merely quote what they tell me the cost to send is... that is to say, I make no money on shipping.

 

In recent times people from Japan and France have asked me about sending a Model III to them, Fedex quotes me $A470 to Europe or $A430 to Asia.Someone asked about sending a Model 4D to the UK and it was also $A470 with Fedex.Needless to say none of these people went ahead with the purchase.People from the USA often ask me about buying and sending items to their country which makes my mind boggle; this is where all the Tandy/TRS-80 hardware originated from so wouldn't it be far more plentiful in the US than here?Any savings made by buying from me would surely be eaten up by the postage costs?

 

However if you are in the US and are really desperate for a computer or partthereof, I'm happy to help out, but just be mindful of the shipping costs, as I say, its a long l-o-n-g way my stuff has to go.

---------------------------------

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.)

---------------------------------

USE SOFTWARE OFF THE WEB ON A REAL TRS-80 VIA YOUR WINDOWS PC:

(Added 28 July 2012)

I just saw a great video on YouTube the other day in which a gentleman who goes by the name of Vintage Volts, and shows a method of connecting his Tandy TRS-80 Model 4D to a PC via its RS232 serial port and transfer software downloaded from the Web to use on a real TRS-80.I thought this was a very handy video as one of the most popular questions I am asked is how to get software from the Web onto a real TRS-80.This method applies to any TRS-80 model fitted with a serial board, and works pretty well.I've tried it with my Model I and 4P and it does work if you follow all the steps.

NOTE: the video is long (over 38 minutes), and extremely detailed, and aimed at a non-technical audience.The flip side is that technical type people may need to skip through various parts but do that at your own peril lest you miss an important point which prevents successful transfer of software to your TRS-80.Enjoy the video, and if you need an RS232 serial board for your Model I/III or early Model 4, drop me a line.

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 2102 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.)

--------------------------------

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 -
snap, crackle, pop and smoke! But Ian was able to fix it.  Another Model I
saved and restored to working order - many thanks!" - Ian Robertson, Adelaide SA.

"As a TRS-80 enthusiast, Ianís 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.

(Added on 16 December 2012)

"dear ian. I've now got three packages. trsdos and other disk are OK. I thank you again, am very happy that everything works. I now try wede, small write programs (basic II). thanks for the games. love greetings walter" - Walter Shrauder, Wien, Austria.

 

"There arenít many individuals on the planet who could have pulled this off.Thank you again for repairing my hard drive.It was worth getting out of bed this morning. Bob B." - Bob Boyd, PA, USA.

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:

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.

----------------------------------

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.

As a serious collector, I follow the Classic Computer Collector's Code of Conduct. The Code of Conduct is listed here for your reference:

 

The Classic Computer Collector's Code of Conduct

 

I do my best to find a home for any classic or unwanted computer.
 

I will return or destroy any personal or commercially sensitive data I find on a machine I acquire, and will keep it in the strictest confidence, should I find it necessary to view it.
 

I will aid users in the decommissioning of their old machines, should they require assistance.
 

I respect active software and publication copyrights.
 

I will, whenever possible, repair the computers in my collection and maintain them in working order, and will assist others in doing the same, to the best of my ability.

 

I actively encourage the repair, maintenance, and use of older computers, in preference to the irreversible alteration of machines and parts for non-computer applications.
 

I actively promote the exchange of computers, parts, and information among collectors, and will refrain from hoarding multiple examples of any item.
 

I actively promote ethical collecting.
