TRAMsoft Gmbh, Swiss know-how ! (part 2)

On the last page of TRAMsoft advert we see “SRS Ing. R.W. Fankhauser” which was one of the best reseller for their modules.
One other was “GEWA COMPUTERS”.
(If some of you have informations about GEWA then please contact me)
Here is an extract from the GEWA catalog 2/84 :
(You can watch the prices on the red page.)



TRAMsoht TOOLs were very well known in Germany as showed by the following article :



Remember that you can have more informations about TOOLS on TRAMsoft website. And you can buy some available extensions too.
Manuals are available for download.

Next time i will show you their storage solution…

TRAMsoft Gmbh, Swiss know-how ! (part 1)

In the 80s we saw a lot of things appear for the Sharp PC-1500. Listings, tapes, memory modules and Eprom … and rare extensions.
In 1983 a company was established in Switzerland by two young graduates of technical high school “Technikum Winterthur” Reto Ambühler and Thomas Müller. With their initials they named their company TRAMsoft.

There are some months I contacted them and Reto was kind enough to answer me. He also agreed to give me a few things which I will soon. I hope Thomas will say us a few words and tell us this wonderful time of the arrival of the PC-1500.

But back to their company and their products … that still exist !
And you can order their last items for PC-1500 and PC-1600 😉

They were interested in the PC-1500 and managed to overcome its limitations both in terms of the Basic language as its features.

Thus users are able to “open” their machines to the environment.
Their best-known products are the TOOLS.
There are 4 TOOLS organized by theme.

TOOL1: Editing utilities
TOOL2: Fast tape operations
TOOL3: Additional BASIC-functions
TOOL4: Statistics and synthetic programming

TOOLS on TRAMsoft website

But unlike the EC-50xA/B Sharp modules, the TOOLS do not come onto the memory port on your machine but in an external box. You can continue to use your extensions CE-151, CE-155, CE-159 and CE-161 and the program modules from Sharp.
All these TOOLS can all be integrated into the same housing. Great, right?

Here is their flyer from 1986:

Reto sent me other versions of their commercials :

Thanks to trade with other people I acquired a catalog of “Ingenieurbüro Walter Speidel” dated 1984. Their tools are already on the market but we can see that at that time the TOOLS have yet no box. It is printed with EPROM circuit, address decoding and a connector.

The prices are quoted in Deutschmark.
At that time I was living in Germany and remember that conversion to Franc had a ratio close to 3 This gives us about 150 euro for each TOOLS.

Ah, perhaps you noticed the initials “Ingenieurbüro Walter Speidel”? This will be the topic of another article by the end of the year …;)

For now I leave you to discover the site TRAMsoft.

Holtkötter PC-Software (RVS)

Do you remember RVS Gmbh ?
RVS means Rasso Von Schlichtegroll.
Everyone using PC-1500 in Germany know RVS, isn’t it ?
The RVS Macroassembler was a major tool for the PC-1500.

But do you remember the software suite sold by Holtkötter ?


The suite PC-SOFT include 7 titles :
– PC-CALC : Make calculations easy
– PC-WORK : All to work with memory modules and tapes
– PC-LEARN : Everything to learn machine language programming with the LH-5801
– PC-PROFI : The function’s library !
– PC-MACRO : The professional Macro Assembler
– PC-BASIC ’84 : The structured Basic like Pascal
– PC-FORTH : The Forth language from the “Forth Interest Group”


Do you need something else to get ready with your Sharp PC-1500 ?
A big memory module ! 🙂

Here is the catalog describing (In german language) each module of the PC-SOFT suite :

Donation ?

Hello dear visitors,

My site tries to gather all the information on the fantastic machine that was the handheld Sharp PC-1500 and its various versions.

To advance this work I need your help.
I’m not talking about donations “money” but documentation, books, hardware, software, plug-ins, accessories Sharp, Tandy … etc to complement this collection and also serve me for trade.

For example, Tandy sold a lot of software for the TRS-80 PC2 (Radioshack Tandy) but I found only rarely.
Besides my Tandy PC2 is not the best form and if someone has one to offer I agree 🙂

There is also the original boxes that I miss. Perhaps you have in your attic?
User manuals?

As you understand, anything can interest me and use me to advance this site.

I listen to your suggestions 🙂

Thank you to you.
