Intel Vintage

About Me

I started out as a Zilog Z80 machine code nut many years ago in my youth. I then migrated onto Intel 8086 MULTIBUS 1 equipment and then on to 80286 MULTIBUS 1 equipment when our software writers ran out of steam on the 5.33 MHz 8086s!

I helped develop a very large control system utilising Intel 8086 and 80286 MULTIBUS 1 products back in the mid to late 1980s and then moved on to other things. I have now moved back to the job I left 25 years ago and picked up again where I left off - with the intent of modernising the system I helped to create.

Hi people.

I have some operational iSBC 286/10A CPU cards and iSBC 012CX memory cards running in a MULTIBUS 1 chassis - but am trying to find some current information for the iSBC 012CX memory board. I believe there has been a number of updates to the board (faster DRAM chips) as the processor speeds have increased.

I notice from the Intel Vintage documentation list that the manual that went with this board was a 145158-003 (which I have) but that there was a change note (146094-001) which I haven't got. I believe the information I need may be contained within this change note.

Does anyone have a copy of this Intel change note?

The particular thing I am interested in is the optimised iLBX read timing to ensure the fastest response to the processor (resulting in at most 1 wait state on the iSBC 286/10A CPU card running at 8 MHz). The memory timing defined in document 145158-003 (from /ASTB to data valid) states that this is 305 ns. I am sure faster access time DRAM was used in later memory boards resulting in a faster time - but I am unable to locate this documentation.

Can anyone out there help?

Cheers,

Dave
