16MB SIMM possibilities?

Open hexbus opened this issue 4 years ago • 5 comments

Would it be possible to get a PCB for the 16MB SIMMS? Thanks for your work on these!

Hello. Was asking also if changing for 4096kword x 4bit could work for a 16Mb simm ?

I'd like to design a 16MB SIMM, but I don't have any way of testing it. In principle it should be relatively simple.

Please do, my javs2 and Combo040 desperately need them :)

If any of you know someone who owns a 16MB SIMM, it would be helpful to get a scan of the front and back.

Is there a 16mb sims version available?

Nobody has sent any photos, and since I don't have any GVP devices that use the 16MB SIMMS, there's no way I can deduce the pin connections.

Let me help you with some pictures of gvp 64pin 16mb sim. The ram used on this board is HYB5116400BJ-60. If you need more detailed scans, please advise. I look forward to you response.

16MB version (beta) is now available.

schlae avatar Apr 29 '25 06:04 schlae

@schlae - I did find a 16MB one a while back - and wanted to give you some more close ups for the cause in case you wanted them. :)
