It runs at 5 MHz MOL just like a PC.
Some 150 even
had the optional 8087. The 150 was one of those ALMOST IBM
There never was an HP 8087 card for the plain HP150, although HP do
acknowledge that 3rd party one exist in the techref.
There was an official HP 8087 card for the HP150-II. I have it. It's
Do you want another one? I left one in a scrap yard yestrday. I have a
TS II but it's working fine and I didn't feel like hacking it up to add the
8087.
strange. When you install it, you cut a jumper on the
motherboard that
disables the 8088. The add-on card contains a new 8088 configured in
'maximum mode' (so the coprocessor interface signals are available), the
8087 and enough glue logic to make it look like an 8088 in 'minimum mode'
to the rest of the system.
That's why I said "ALMOST IBM PC compatible"!!!!!!!!!!!!
OK, it runs MS-DOS, and there's an 8088 in
PC compatibles. I have at least eight or nine of
them and they're all
It's hardly PC compatible. there, but the video system is totally different, as is
the serial system
(the HP150 uses an NEC 7201 chip), the disk controller (disk drives are
interfaced using the HPIB port),
Yes and the disks aren't in a MS_DOS format unless you added a 9127 drive.
etc. Any application that hits the
hardware (or even the BIOS?) won't run on the
HP150.
Unless you get the TSR that emulates the PC BIOS. It doesn't fix all the
gotchas but it helps.
I prefer to call it (and the Apricot, Sirius, Sanyo MBC555, etc) an IBM
Incompatible. Meaning a machine that runs MS-DOS, but sure as hell
doesn't run much PC software.
Sure it will IF you buy it from HP! $$$$$$$$$$$$$$
