Hi All,

Title says it all. I have built a budget 1mb chipmem board for the A600. It will be ready in about 3 weeks. there will be 2 prices for it, with/without the RTC circuit

79719

Price will be $34 US with clock circuit and $29 without the clock circuit components. The battery is a CR1220 and cannot be included due to mail restrictions.

Sounds good, however both my 600s already have chipmem expansions in them so I won't be getting one of these (at least for the moment). One of them I even paid big bucks for on ebay, but that was before I knew Amibay existed and that you could actually get stuff for Amigas at reasonable prices. :)

Since shipping can be expensive it is always nice that you can offer multiple products for future customers.

I was just about to order your old model, right this minute! I'm new to Amiga, so I have to ask: What is the RTC/Clockport good for?

I also read that the 4mb ram expansion would speed up the Amiga by 30%. So what about the 8mb expansion? Would that speed up the Amiga600 even more?

RTC means real time clock. Mean your Amiga's clock will keep running even while it is off. Useful if you are running from HDD and care about time stamps on your files. Otherwise it does not make a difference.
Clockport is for attaching peripherals like the RapidRoad USB controller. The clockport is standard on the 1200 motherboard.

The reason the fast mem expansion will speed up the Amiga is because chip mem is slow as it is shared with all the custom chips. The custom chips cannot access fast mem so the CPU will be able to work faster when the program is running from fast mem. Whether you have 4MB or 8MB does not make a difference here, however if you are using WHDLoad, 4MB might not be enough for some larger games to enable preload of the game (much faster than swapping out and loading during the game).

I think my A600 is on the way soon and this board is candidate for extension. Can someone explain me how much Chip and how much Fast for best ECS software compatibility?

kipper2k

the a600 comes with 1mb chipmem and can support an extra 1mb chipmem and 8mb fastmem. For best WHDload compatability you need at least 2mb chipmem and minimum 4mb fastmem, 8mb recommended

Hi All,


I finally got the 1mb chipmem board for the A600 finished. I decided to call it the K601MB.


The board has a few features that i hope people like,


- 1mb chipmem
- RTC clock (optional) with clock disable jumper
- Yulquen74's multiROM select option (optional, need permission to use it first)
- clockport (nothing to try it with)


Here are some piccies :)




first of the board itself...


http://www.kipper2k.com/k601mb/k601mb.jpg






Show the memory available (the extra 1MB chipmem is located at $100000 - $1fffff)...


http://www.kipper2k.com/k601mb/memory.jpg




Next shows the K601MB hooked up to control the rom select. This
A600 has KS1.3 and KS 3.1 on a 27F800 EPROM that can now be
controlled via the K601MB board. 1 wire has to be connected from
the K601MB board to pin 1 of the ROM chip. You can also use a
27F160 for 4 Roms by hooking up a second wire from the board to
pin 42 of the 27F160

withdraw interest. Think brian is too busy cranking out vampires v2 now, to make any chip ram modules.
