The repairs of my #Enterprise64 continue. It can run an old 32K ROM but not a newer 64K ROM. Also it fails the RAM test. Replaced the old soldered RAM chips with new socketed ones. Same result. Main suspect now is one or more of the address lines on the PCB. Unsure how to test it, as one of the ASICs does some clever memory banking, which probably means they're not directly attached to the #z80 CPU.
I'm way out of my comfort zone here, but I'm trying to diagnose and fix a 40 year old #vintagecomputer.
Trying to fix a broken vintage #Enterprise64 with limited skills. Suspecting flaky RAM.
First impressions of the #OSSC #upscaler (v1.8) connected to an #Enterprise64 through a SCART cable. Looks good so far - picture is sharper and there is a lot less color bleed than on a cheap noname device.
Firing up #PolyPascal on my 40 year old #Enterprise64 for the first time in probably 35 years. Actually, I'm not sure if I ever go PolyPascal running on it, or it was just the previous version, Compas Pascal. Glad to see an old #Danish friend from the #CPM era again though. It's been too long.
As previously mentioned, I managed to get my hands on another #Enterprise64 from the mid 80s. I disassembled it yesterday and made sure it was in working order. Nothing noteworthy, apart from cleaning it up and snipping a couple of mm's of the super thin wire tape for the keyboard, which is notorious for breaking. Also, a 1MB memory expansion was added, which is is insane for a system that was born with 64K. It's now technically an #Enterprise1088 :-)
Developed in the UK, it comes with IS-BASIC, a word processor, has 256 colors, stereo sound, runs CP/M and reads FAT floppy disks. Pretty cool for a 40 year old system, eh?
This is my third Enterprise machine. Currently two are working - my original (S/N 000828) which was gifted to me back when my dad started importing them, and this latest one (S/N 030490). The third one is unfortunately dead at the moment.

Some 40 years ago, my dad took a leap and decided to import and resell the #Enterprise64 microcomputer from the United Kingdom. This was indeed the era of the "micro", and lots of options were available like the #Spectrum, #Amstrad, #NewBrain, #Lynx and numerous others. Unfortunately competition was hard, and the Enterprise was delayed for almost a year. Eventually they went bankrupt and all stock was exported to Eastern Europe where it got a second life among some very hard core enthusiasts. Very few were actually sold in Denmark - I would assume less then a hundred - and today I managed to get my hands on the third one in my collection. Inherited from his dad, the seller had no idea what to use this for. It's very much a special item, and very far from the mainstream like the Commodore 64. It is nevertheless a fascinating machine, sporting a #Zilog #Z80 with support for up to 2MB RAM. The operating system also contained IS-BASIC, and was a bliss to work with.
And I only just found this. I didnβt realise the Flan name actually made it into production.
This means itβs a revision 4 board, from the first production run. The run with bugs in the video chip and ROM.
The Enterprise keyboard layout is coming along nicely. The photos show a printout of the design under the matrix.
I had to redo the horizontal positioning when I realised they used the same size matrix for both dimensions and the keys are 19mm x 19mm. The error was only 1mm across the width of the board but thatβs plenty enough to cause problems.
The function keys and joystick are the only things which arenβt on the matrix.
