And they are very nice indeed. In case you have not looked, there is an HP-87 version of the SuperROM, which includes:

Adv Programming ROM 1 & 2
Assembler ROM
Matrix ROM 1 & 2
I/O ROM
Extended Mass Storage ROM
Plotter ROM

(in truth, you can only use 7 of the above 8, but still, it's much cheaper than physical ROMs.)

Yes, thanks for the hint, I know about PRM-85.
In fact a year ago I initiated the modification of PRM-85 to match the needs of HP-86/87 users better, i.e. the preprogrammed ROM codes were adjusted.
My custom "PRM-87" hosts 10 ROM images ( 8 plus 2 in a second EPROM with individually configured ROM codes via the DIP switches).
I wonder why only 7 of 8 ROM images can be used in the PRM-87 that officially is for sale now?

I only collect HP 86/87 items, no one here who needs the HP 85 module?

I just realize that I can offer also a HP 98151a Rev. B Program Development ROM!
