I asked about www.terminal-entry.de romflash:

Quote:

i have only make some pcbs for my prototypes.... some of the projekts went to a small production batch, but the costs for 2 oder 3 pcbs and
part assembling are too high to get enough orders.... My other projets have only one pcb for one product so the costs were lower.... I will release the documentation for the ROMFlash soon, so you can make youre own pcbs

Floppyfix, mouse and external keyboard interface PCBs i have on stock, if you need some...

So I guess Amigakit etc needs to manufacture and sell those if you want ready-made ones.

Wow, simply great, now if someone wants to build&sell them, you sure count me as a buyer.

I have a bunch of 512KB 5V flash in TSOP package and also a bunch of 512KB 5V SRAM. I do not think I will use them.
Any takers ? I just ask for the postage to be paid.

TSOP' Flash and SRAM's ?

how many is a bunch ?

my GB1000 could be in your debt, as well as my A2000/600 and 500+ =)

Now is there anything Amigery your looking for? it would be nice to return the favour =)

rkauer · 10 November 2009, 07:38

Damn! Zetr0 came first.

I was thinking in another pair of projects using SRAM modules...

@ Zetro and Rkauer :

I think I have 100+ of each.
I wanted to use them for some miggy projects but I am too busy with the MCC.
Give me some time this WE to count them, pack them and maybe unbend some pins.

Regards,

Frederic

IIRC, the SRAM are 55ns or 45ns speed, maybe too slow for the GBA1000.
I am looking for an A500 (or just the mobo) so I can experiment my TG68 based accelerator on it. I am not in a hurry. Maybe next summer after my move back to France.

Funny enough.... I actually have a spare A500 motherboard as Jimmers (Jimbob005) sorted me out an A500+ motherboard.=D

its yours, whenever you want it =D

rkauer · 13 November 2009, 00:43

I have 3 A500 rev5 boards here, they are yours. But postage is outrageously expensive in my country.

Hi Zetro et al.

If you are keen on doing this you may be interested in these:
http://cgi.ebay.com.au/ws/eBayISAPI....m=220455183552

"2pcs ST-M27C322 Eproms" $4.90 + $5.50 shipping.

Datasheet to suit at:
http://www.alldatasheet.com/datashee...S/M27C322.html

DIP package, so easy to fit on normal .1" experimenter board.

By switching the high address lines you can have quite a number of kickstart images to play with at the flick of a switch.
Easy to configure 1MB image support too.

Top2048/2049 programmers will program these, though I expect you will have a programmer already

Bought myself a few sets which arrived today!

Cheers,
Red

@RedSkullDC

y'know... I actually have 4 different programmers, its a collection =D

my favourites are my Willem 4.5 *has ISP header* and Genius G540 =D
