I'd like to discuss VME boards here. VME based systems are highly modular and was introduced early 80ies as a standardized continuation of Versabus. At first only 68000 family was supported but over the years many CPU types and i/o boards were adapted and the latest standard even support 64bits aka VME64. I intend to contribute drivers for a few early ones suitable for emulation. If you sit on information or ROMs fitting this description please let me know.

First out is Force Computers CPU-1 for which I have just filed a pull request. Or you can grab it at https://github.com/JoakimLarsson/mame.git branch m0165_fccpu1_3

layout files and instructions are found here: https://drive.google.com/file/d/0B685nj_1DkdueXdLR2N4STd4RWs/view?usp=sharing

Do you have anything on Force SYS68K series? It was apparently OEM'd in Soviet Union and repackaged into a workstation product (skeleton driver -- besta.c)

edit: d'oh, it *is* the sys68k series :-) I strongly suspect that earliest models of Besta used original Force components and later models used redesigned/customized ones.

The CPU-1 is the very first SYS68K board and I think I have the first revision too super seeded by the CPU-1B/D described here: http://bitsavers.trailing-edge.com/pdf/forceComputers/1988_Force_VMEbus_Products.pdf.

I'll take a look at the Besta and see if I can merge the two drivers, I didn't know this, thanks for the pointer!

Edit: Yes, Besta seems to follow the address map and specs of the SYS68K/CPU-30 series launched in Q2/1988, I am only puzzled by the SDRAM which sits in the User EPROM area instead of in the designated SRAM area. I believe that Besta should be a clone if there was a CPU-30 driver.

There's a native SysV Unix OS for it, and a Linux port, btw -- https://github.com/shattered/linux-m68k

Plus lots of documentation, in Russian obviously, some in electronic form.

By the way, it's nice to see more new MAME developers from Sweden. Hej from Stockholm! smile

Great, maybe I just outline a CPU-30 driver then and try to include the features from Besta as a clone, however I like to have some real hardware too, I am a hands on guy smile I put it on the todo list.

Right now I am struggling with a Heurikon hk68/v10 based on 68010, and I got a Mizar 8105 and a Motorola MVME-350.

Tack detsamma JD!

I'll check if any Besta hardware is available for sale or donation (likely the former, though)...

I have just submitted a pull request for a new VME board, you can grab it at https://github.com/JoakimLarsson/mame.git branch hkv10_2

The Heurikon HK68/V10 VME CPU board

Features: - 68010 CPU @ 10 MHz, 128Kb ROM, 1Mb Dual port DRAM, 1 CIO Parallell interface, 2 serial ports,
1 SCSI interface with support for up to 8 devices, A16/A24 VME bus, Optional MMU, DMA, FPU

This is an advanced 68010 based SBC for VME based industrial applications relesed around 1985. The
intended use is in a VME cage together with VME compatible I/O cards and specifically Heurikon own series. This
manual for Herikon UNIX gives a detailed view on a industrial UNIX configuration:

http://bitsavers.informatik.uni-stuttgar...Guide_Apr87.pdf

Mame emulation currently supports:
- CPU
- 128K System ROM
- 1Mb of RAM
- System ROM Terminal interface

I just uploaded a couple more Heurikon manuals to bitsavers
