68030 TK - Another accelerator card for Amiga A500/A1000/A2000 designed by Matze (aka Matthias Heinrichs)

Ok,
here is information for users who are able to update their cards by itself
(to be able to operate with 64MB expansion):

Following five resistors need to be changed from 4k7 to 1k (all resistors are 0603)
R2, R13, R15, R20, R22

R24 - need to be removed!

R3, R9 - 470R

if You have correct resistors installed - You need to update firmware on both cards:
TK itself and 4MB card too

Be aware: TK has Lattice cpld,
it can not be updated with Xilinx programmer!
Attachment 152993

firmwares for both cards (TK & 4MB) are attatched and need to be updated!

PS
thinking about acception of 4MB expansions as a partial payment for 64MB cards
(to resell them to new users)

Would be interested in the update to 64mb

Interested in upgrade 2 cards that i get from you.. tell me how to proceed.. thanks

Interested in update + I would like to order relocator board (can we ship together?).

Interested in upgrade from 4MB

I have your excellent TK68030 card, am interested in a RAM upgrade for it please :)

Did anything ever happen with this?

Hi,
sorry, had a slowdown due COVID, but all sorted now, have built 8x 64MB boards,
start to sending payment infos to interested persons.

For those, who can solder and is able to upgrade TK Part, here is the updated Resistor list:

Resistors:
​R1 -> 10R0 -> 10
R2 -> 01B -> 1k
R3 -> 471 -> 470
R4 -> 472 -> 4,7k
R5 -> 472 -> 4,7k
R6 -> 472 -> 4,7k
R7 -> 470 -> 47
R8 -> 472 -> 4,7k
R9 -> 471 -> 470
R10 -> 470 -> 47
R11 -> 470 -> 47
R12 -> 472 -> 4,7k
R13 -> 01B -> 1k
R14 -> 470 -> 47
R15 -> 01B -> 1k
R16 -> 470 -> 47
R17 -> 472 -> 4,7k
R18 -> 472 -> 4,7k
R19 -> 472 -> 4,7k
R20 -> 01B -> 1k
R21 -> 472 -> 4,7k
R22 -> 01B -> 1k
R23 -> 01B -> 1k
R24 -> nicht bestückt
R25 -> 472 -> 4,7k
R26 -> 472 -> 4,7k
R27 -> 472 -> 4,7k
RN1, RN2, RN3, RN4, RN5, RN6, RN7, RN8 -> 472 -> 4,7k

Firmware:
once resistors are sorted You'll need a Lattice cpld programmer for Firmware update
(Visit Matze's Gitlab page to obtain newest FW)

CPU:
If You use EC - it need to be of last two batches. have used original CPUs from USA, so these working fine usually, chinese reprinted CPUs doesn't work unfortunatelly
Ceramic CPUs with MMU support is also working good

Boards Price:
Unfortunately CPLD prices are riding rollercoaster, these was sky high due COVID, these are back to normal now,
so at the moment i can offer complete built 64MB expansion for 65€ shipping everywhere in the world is 8,50€
Can't ship to Australia due COVID atm... :(

Hello Amiga fellows!
im glad to report that testing and adjustig phase of 64MB RAM card is over,
and some cards are available,

Please see first post about available options,
and feel free to obtain Your card now!

Interested in One full set for A500 And another dul set for A2000. Send me pm with details. Shipping to spain. Thanks
