Thanks I have a tunix and ALL the carts for it.
interesting piece of NZ History (and global history) like the foun.tain ! same CPU etc.
Most importantly there are some real "chunky pixels" and low memory specs that I like.
Did you know half the RAM in the Tunix is disabled by the hardware design, ie the last address line is hardwired to ground, disabling half the static RAM chip. If I was in charge I would have kicked the board designers butt
Did you know the foun.tain does even have a single RAM chip ! good to purchase as you know they dont have any bad 2114's or 4116's
(The Tunix has two nibble wide Static RAM's) If you have ever tried to open one, its a mission to get through the ballast shielding (erm ok I actually meant tin sheilding, but I like to refer to my vintage stuff in terms of battle requirements and thermal nuclear fallout protection levels etc, like the Atari's are stealthy and wont show on radar, but a Tunix would kick its butt in a head butting competion! due to its ballast rated armour)
I wrote much code for the 2650 including an assembler and disassembler, it is accurate enough to disassemble the entire Tunix 40-50 cartridges and re-assemble them to 100% identical binary images.
One problem with purchasing it, That is - It will never be worth $50
saw one go for $15 dollars few weeks back, but then again, skys the limit on trademe lately, good time to cash up a collection,
Tezza and Matdawson should be worth a mint on the stock market soon
yes I am jealous much !
