The Nascom Home PageLast update: 2018-04-02 TT
Added a (long-overdue) fantastic contribution from Thorleif Bundgaard:
"Im searching for an old NASCOM Dungeon like game, where the task is to stop a bomb from exploding, but didn't find it.
I got into contact with a guy 'Anders Hejlsberg' later to be one of the founders of BORLAND. He had made the first real compiler for the NASCOM, called 'Blue Label Pascal'. In 1984 Anders gave me the source for the floating point routines used in this Pascal. The special thing about this code is that it keeps all its computations on the stack, so you dont have to set aside some RAM areas. And the code is completely relocatable.
I also have a printed description that Anders made (In Danish), Most is just CALL descriptions, so I guess that anyone speaking English will understand our language well enough, however I also did a translation."
I found the copy of NimBot on your web, and noticed that it has incorrect graphics. This is very understandable, considering it was typed in from a printed magazine.
And due to Nascom BASIC having a bug with LIST expanding tokens within strings, this makes guessing the correct graphic for the garbage almost impossible!
When C&VG asked for permission to publish NimBot, they didn't ask for any help with the graphics - they just printed it. I laughed when I saw the copy : ``Have fun typing that in!"
Recently, I was salvaging data from my ancient Nascom floppy disks, which wasn't easy; as my disk controller died about 20 years ago.
I wrote a disk reader for my Tatung Einstein, and managed to read most of the disks. One of the disks had a NimBot file, but it was corrupt. Luckily, the sector with the graphics was intact, so I combined it with the copy from your web to recreate the original."
Thank you to Carl for the update and the backstory (I appologies for taking two month to convert the NAS to CAS).
As I was doing some research on the early format of the Level 9 adventure games I discovered your site http://www.nascomhomepage.com/ a few months back.
In particular, I noticed the entry "Colossal Adventure 16K and 32K version (Level 9)." and the files therein. I knew very well the Level 9 Colossal Adventure, but I was not that familiar with Level 9's early work on the Nascom. Assuming that the "32K" version was something Level 9 did early on, predating the work on other micros, I started to disassemble the file to understand how this differed from what I had seen on C64, the BBC etc. After hacking together a z80 trace tool I managed to re-engineer the text compression routines in C (the text compression is based on Huffman variable bit-encoding) and I could list the various texts in the game. Only to find the text "Adventure 32k copyright (c) 1982 Michael J. Evis" (message #200 of the message texts). A further look revealed that you can provoke this text in-game by entering "AUTH" for Author.
Just wanted to let you know that you should consider changing the text on your page to credit Mr. Evis instead. A qualified guess is that the "32K" code is similar to what was released for the ZX Spectrum a year later (worldofspectrum). The Spectrum version has earned a place in the Adventure Family Tree.
The "16K" code is a shortened version. As I can't find any credits in this file I am not sure who wrote it. Maybe the supplier of these files can confirm that the 16K version is also written by Michael J. Evis?
Out of historical interest it would be nice if someone in the Nascom network could identify and supply the actual "Colossal Adventure" file by Level 9, as I am unable to locate this elsewhere.
A group of members has written a DOS and CP/M 2.2 for this interface. The interface was switchable for 5 and 8 inch drives. The picture of the prototype board for this interface and an eprom programmer.
A friend of mine (Mick Waters) persuaded me to buy a Nascom 2 (I was thinking about a CompuKit UK 101, a close shave!) as he has already bought one and said it was much better than the CompuKit. Well while I was building mine we purchased this book and spend an entire night typing it into his 16K Nascom 2, only to find that it wouldn't run as there wasn't enough RAM.
Needless to say we quickly borrowed my 4116 chips from my N2 kit (I was quite nervous) to up his 16K to get 32K so we could run the game J (at least we were able to save it).
Some years later I upgraded the N2 to a CP/M system, courtesy of a Gemini Disk card and merrily converted my favourite game to CP/M. But things moved on and I bought more computers but didn't stop using my CP/M Nascom 2/Gemini hybrid system until I bought my first PC (around 1994).
However thanks to CP/M emulators and vnascom I have been able to re-convert this game back into the Nascom 2 MBASIC version. I can't guarantee that I haven't made any typos in this version given that it has been ported to and from CP/M but it seems to run just fine in vnascom. I hope that it is of some interest and include it here."
Ken Smith writes us that "I have available a nascom2
computer plus 48k memory card plus graphics card plus PIO card plus
twin 51/4 floppies with card plus power supply. Seems to be working
ok. Free gift to enthusiast.

The Nascom (1 and 2) were computer kits from the UK based Nasco, later Lucas, around the Z80 processor, sold in the early 1980s. This remarkable piece of hardware contained:

VNascom is an alternatively emulator written by Constantin for Windows. The latest version is
Virtual Nascom Version 3.1 for DOS/Win9x/ME.
The current version has bit level correct screen output and complete keyboard emulation. It run all the programs We've tried, which includes most games available. New in Version 3.1: CP/M Version 2.2 runs on standard Nascom screen as well as on the AVC.
Hans Rietveld contributed a front-end for Vnascom.
A new Nascom 2/3 emulator version 1.2 in Java written by Richard Espley is available.
One of the best Nascom games.

Interesting though that part 4 came out in Feb 1978, as this puts part 1 in about Nov 1977 - so it seems the design was being published at about the same time that the Nascom 1 was being first produced? Open source doesn't seem to be a modern invention then.
Paul provided parts 4 & 5 of the series, while John provided the remainder and converted Paul's to space saving PNG format. Thank you both.
