COMPAQ Machines
|
||||
---
|
||||
|
||||
This is an evolving (and roughly chronological) list of COMPAQ machines from the 1980s, which PCjs may eventually
|
||||
support:
|
||||
|
||||
+ [COMPAQ Portable](#compaq-portable)
|
||||
+ [COMPAQ [Portable] Plus](#compaq-portable-plus-aka-compaq-plus)
|
||||
+ [COMPAQ DeskPro](#compaq-deskpro)
|
||||
+ [COMPAQ DeskPro 286](#compaq-deskpro-286)
|
||||
+ [COMPAQ Portable 286](#compaq-portable-286)
|
||||
+ [COMPAQ Portable II](#compaq-portable-ii)
|
||||
+ [COMPAQ DeskPro 386](#compaq-deskpro-386)
|
||||
+ [COMPAQ Portable III](#compaq-portable-iii)
|
||||
+ [COMPAQ Portable 386](#compaq-portable-386)
|
||||
+ [COMPAQ 386/20e](#compaq-38620e)
|
||||
+ [COMPAQ SLT Series](#compaq-slt-series) (SLT/286)
|
||||
+ [COMPAQ LTE Series](#compaq-lte-series) (LTE 286, LTE 386)
|
||||
|
||||
At the moment, only the [COMPAQ DeskPro 386](deskpro386/) is supported, but now that we have ROMs for a few other
|
||||
COMPAQ machines -- most importantly, their **first** machine, the [COMPAQ Portable](/devices/pc/rom/compaq/bios/portable/) --
|
||||
more should follow.
|
||||
|
||||
### Regarding The COMPAQ Name
|
||||
|
||||
As best I can tell, COMPAQ preferred to print its company name in all-caps, so that's my practice as well.
|
||||
|
||||
However, it seems that sometime between the release of [COMPAQ MS-DOS 3.10](/disks/pc/dos/compaq/3.10/) and
|
||||
[COMPAQ MS-DOS 3.31](/disks/pc/dos/compaq/3.31/), there may have been a shift in policy. Both products still
|
||||
called themselves `The COMPAQ Personal Computer MS-DOS`, but in 3.31, the copyright string changed to
|
||||
`Compaq Computer Corp.`
|
||||
|
||||
Their all-caps practice also extended to at least *some* product names (eg, the `COMPAQ DESKPRO`), but I'm not sure
|
||||
how strict they were, and I'm decidedly less so, which is why I use the name `COMPAQ DeskPro`.
|
||||
|
||||
The rest of this page will be used to collect information about the machines listed above.

Released in late 1986.
