Hey there, I picked up a very clean PET 2001N-32 a couple of weeks ago from an electronics disposal (it was bound for the trash!)... And it has turned out to be perfectly working. Anyway, I thought I'd had a go writing something for it, so have turned to CC65 which is working reasonably well...

I've just bought a replacement 286 motherboard for a generic Headland HT12 board which I've owned since new for the past 30 years and which has finally stopped working :( The new board is almost exactly the same as a Peaktron PA286-SMT board, as described here...

So this is the first time I've seen one of these - it's a Force SPARC-CPU-5V; according to the manual it's essentially a SS5 on a 1 to 2 slot 6U VME card. I managed to pick it up cheap from a recent Ebay auction and hit lucky - it came with the optional SBUS frame, which stacks it from a single...

I've recently acquired a nice IIci with a Daystar 040 turbo, Radius 24bit display, network card and a healthy amount of ram (80mb). I'm planning on replacing the existing 160mb SCSI-1 drive with a IDSC21 SCSI/IDE bridge and a IDE/CF adapter. I'll be installing System 7.6. I believe I need to...

I now have obtained several versions of the SCO Xenix Development system this includes: 2.2.0 2.2.1 2.3.0 It works, but won't build much modern software - for that you need to install GCC via several steps 1. Install the tarfile of gcc (1.40c) + gas + gdb 2. run fix.h.xenix 3. Install the...

I'm playing around with SCO Xenix within Virtualbox at the moment and have hit a bit of a problem with serial ports. Other than floppies, really the only way to get content in and out of the vm is via the emulated serial ports - so I'm using the well documented technique of used named pipes...

Looking for 68pin 80286 to fit in a plcc socket in order to replace a surface mount N80L286-16/S that I removed in an ill-advised attempt to fit a IBM 486SLC2 upgrade card :( Minimum of 16MHz, but if anyone has a 20Mhz part that would be even better. I'm in the UK.

Hi, I'm considering the feasibility of removing the surface mount AMD 286-16/S from my generic HT12 286 motherboard and fitting a (surface mount, not through-hole) 68-way PLCC socket to accept one of the 8550-Z 286->486SLC2 upgrade modules that are commonly seen on Ebay. However, before going...

Hi, the Headland HT12 286 chipset has hardware EMS support. There is an early version of AMI BIOS that I've downloaded and burned to eprom that adds an option to the CMOS settings to partition any on-board extended memory into expanded and extended (eg I have 4Mb - it allows me to add up to...

Hi, anyone come across an adapter that would plug on-top of a surface mount PLCC (an AMD 80286) to turn it in to a PLCC or PGA socket? Ie to make it suitable to plug in an IBM/Kingston 286 to 486SLC upgrade (which are designed to plug in to either PLCC or PGA sockets). Could such a thing be...

Hi all, I'm hoping to get larger disk access via XTIDE Universal BIOS on my no-name 286 system - I've tried Ontrack Drive Manager and while it detects, partitions and formats my drive to full capacity, I cannot boot anything via the Ontrack 'Insert a floppy and press space to boot an OS'...
