The Lynx 48 and Lynx 96 share the same main board but with a different RAM and ROM memory layout.
**(1)** Motorola 6845 display controller, in text and graphics modes\
**(2)** Rarely used I/O chip, the Intersil LM64021, compatible with the more common 6821 chipset. Manages almost all of the system ports.\
**(3)** 24 KB BASIC ROMs (3x2764). The Lynx 48 board only has 16 KB of ROM memory (2 IC and an empty socket)\
**(4)** Z80A CPU, here a Sharp version\
**(5)** Keyboard connector\
**(6)** 64 KB RAM chips (8x4164), replaced with 16 KB chips (8x4116) in the Lynx 48\
**(7)** 16 KB expansion card. A third bank of 16 KB is soldered on the main board\
**(8)** Internal connector connected in parallel with the external expansion connector.

The Lynx 128's mainboard was completely redisigned to afford larger RAM capacity.

**(3)** First 64 KB RAM bank (8x4164 chips)\

text: We had one of the first Lynx computers. My brother and father sneaked off to the NEC (without telling me) and attended one of the first ''Computer Shows'' in the UK open to the public. They spent the day (supposedly) bench testing various offerings before settling on a Camputers Lynx. Our parents had decided that a home computer would be a good investment and I was hoping that they would decided to get a ''Spectrum''! Both my brother and Dad argued that the demand for one would be huge and even then supply issues abounded,so the purchase of a Lynx was decided. They returned home that evening full of themselves, and much to my annoyance at where they had been without me, announced what they had decided over the tea table. The machine was promised for delivery in short order....... From memory I think it took Camputers at least 4 months after the specified date to get the machine to us - on its arrival my brother was delighted - I on the other hand pointed out the total lack of software
support for it, and that the majority of computer publications at the time pretty much ignored it too! We only every had one game for it, based on ''Star Trek'', it was actually pretty good, but had a stupid timer mechanism which meant you could only play the game for about 20 mins before it simply restarted! TBH I couldn''t be bothered with it, primarily because my school didn''t even have a technology department or anybody on the staff who was interested in computers enough to engage with pupils. I think my Dad ended up with about half a dozen of them and various extra''s like a bloody great monitor. The whole lot eventually went to the recycling tip, along with a BBC Model B etc.

Wow, I''m speechless.\
I owned a Lynx, my first computer.\
In fact I loved it so much I went on to do a degree in IT and have a 30 year (and hopefully more) career in IT.\
I used to live in Bradford and I wanted a TR-80 or a Spectrum but I bought a Lynx and I was delighted.\
It''s like reading about your first girlfriend, except she didn''t go on to marry your best mate, she died and went to computer haven.

I was one of the founders of the Norwegian Lynx User Group.\
We had a few members around the country and released a handfull of user magazines before Camputers went down.\
I still have some copies of the magazines.\
We also modified the ROM with some special functions which were added to the interpreter and also we put in Norwegian national letters on spare space in the character table in ROM.\
I also had to build my own floppy controller from scratch as it was impossible to get a controller at the last days of the Camputers. I hardcopied a friends controllerboard by beeping track by track.\
I managed to get the new board work in my first attempt and were pretty proud of myself on that time.\
I got a Lynx 96 and Lynx 128 w/ CPM/M today.

text: Oh happy days. We (myself and a friend) had a shed load of these at one time I think they all ended up in a skip! :-( we wrote a word processor that sat in the third eprom slot, an assembler and a dissasembler. We also finished off the CPM and had it running a treat We used to sell the Computers, hardware and our software through Pheonix software in Manchester. Although the basic graphic system was slow by using assembly routines it could be sped up significantly. also using the alternate graphics page ment you could prepare the display in the back ground and then simply switch banks for an even faster appearance. I still have much software on disk and many LUG magazines, and I would love to be able to get hold of a Lynx now for nostalgia.

I have updated the emulator significantly over the last few years.
The current (as in released on the website) Win32 (VC++ and VB) version is 8.12
Running on 2000,XP upwards or under WINE
There are also now running versions for:
DOS 32 Bit under the DOS4GW extender\
Win32 SDL + FLTK\
Linux SDL + FLTK\
Raspberry Pi SDL\
An unfinished source for a PIC 18F + Parallax Propeller combo
These will shortly be released on my website.
I''m still on the lookout for more software written for the system.
Best Regards to all

Im a computer collector from Denmark, I got a Lynx 96K and would like to add a diskdrive, and have found a schematic from camputerslynxinfo, but there are errors in the diagram. Then i saw that Peter Lenge from Norway write here in this forum, that he built his own interface, is it possible that You Peter would share Your diagram with the rest of us ? I would be very happe to get in contact with You. I got equipment to make real PCB''s - proff.

I remember that in Basic, the BEEP or SUUND commands stopped all on screen graphics movement for about 1/2 a second!!! My Lynx suffered from a row of bright dots/pixels down the left hand side of the screen. Although it went for repair on two occasions, it always came back with the same problem.\
There were virtually no good games for the Lynx and I always envied those Spectrum and BBC owners :-((

The Lynx 48 was a competitor of the [Sinclair Spectrum](/museum/sinclair-zx-spectrum/) and the [Oric 1](/museum/oric-1/). It was a good machine but its main problem was a lack of software. Several models were available with 48 KB, 96 KB or 128 KB RAM, and it was possible to reach 192 KB with on-board RAM expansions! There is even a monitor in the Lynx's ROM which allowed the user to write and edit programs written in machine code.
The 96 KB and 128 KB versions featured 4 KB of additional ROM memory (mirrored twice for obscure reasons) with lots of extra commands for sound effects, such as laser and klaxon, and for using 24 KB of dedicated RAM as data space.
The Lynx Basic has really cool features, unseen on other systems of its category, like REPEAT-UNTIL and WHILE-WEND statements, and automatic indenting of procedures! The graphic possibilities were excellent, especially with the 128 KB model, and CP/M could be used with the optional 5.25" disk-drive and 96 KB or better models.
However, the Lynx had no great success outside Great Britain. The designer of the Lynx is John Shireff, an ex-drummer.
Some hardware devices on the bus had potentially contentious outputs. This meant that you had to be quite brave if you wanted to program in assembly language - if you made a mistake, you could damage the hardware itself. This was highlighted in the user manual!
Camputers ceased trading in 1984. Several companies expressed an interest in buying the business, and in November, 1984, a firm called Anston Technology took over. A re-launch was planned but never happened, and in June, 1986 Anston sold everything - hardware, design rights and thousands of cassettes - to the National Lynx User Group. The group planned to produce a Super-Lynx but was too busy supplying spares and technical information to owners of existing models, and the project never came into being.
